[Audio] On the 4th to 29th of September 2023, Sittinan Muanchaona of the Metropolitan Electricity Authority's Power System Research and Innovation Department will introduce a photovoltaic system, a MEA grid requirement, and the modernization of the power distribution system. This can positively affect the global energy system and provide the ASEAN countries with more efficient and reliable electricity. Our research and innovation department has put significant resources and attention into this project. With the help of the ASEAN countries, we are optimistic that this period will be successful. Let us collaborate to modernize the power distribution system and create a better future for the ASEAN region..

[Audio] Over the past century, the world primary energy resource has increased by a factor of 10. Traditional sources such as coal and biomass still make up a sizeable portion of the resource, but renewable sources have increasingly become a major factor. This September, the Metropolitan Electricity Authority's Power System Research and Innovation Department, led by SITTINAN MUANCHAONA, will roll out PV Systems, MEA Grid Requirements and modernize Power Distribution Systems in ASEAN countries. This highlights the rapid progress we have made towards renewable sources, and we can only look forward to the potential these sources offer..

[Audio] The global electricity capacity and generation figures show that renewable energy is playing an increasingly significant role in the global electricity infrastructure. To further this progress, from September 4th to 29th 2023, the Metropolitan Electricity Authority's Power System Research and Innovation Department, led by SITTINAN MUANCHAONA, will introduce a photovoltaic system, MEA grid requirements and modernize power distribution systems in ASEAN countries. This initiative is meant to enhance accessibility to energy in the region while also encouraging a switch to a green economy. Our current data is a testament to our effort to promote the use of clean energy and expedite the transition to a sustainable future..

[Audio] ASEAN countries are set to embark on a significant development from 4th to 29th September 2023, with the introduction of the PV System, MEA Grid Requirements and modernization of the Power Distribution System. Spearheaded by SITTINAN MUANCHAONA from the Metropolitan Electricity Authority's Power System Research and Innovation Department, this project is poised to be a major milestone in creating a more secure and sustainable energy system and distribution grid. It serves as an important step in the global energy market, demonstrating how collaboration between experts from different fields can have a significant impact..

[Audio] In ASEAN countries, it is important to understand the two factors for energy resource usage before discussing the introduction of PV Systems, MEA Grid Requirement, and the modernization of Power Distribution System. In terms of quantity, renewable energy sources such as Solar and Wind account for the highest quantity with 3,850000 and 2,250 EJ yearly, followed by Coal with 32000 EJ in 130 years and Oil and Natural Gas with 11000 and 7,144 EJ in 50 and 52 years. In terms of quality, combustible fuels may vary in calorific value, moisture content, ash content or other factors, whereas non-combustible resources may differ based on radiation per sq.m. per day, and wind velocity, and so on. Fossil fuels, such as Coal from specific coal mines, or Gasoline from Algerian oil fields, come with the benefit of an identifiable location and stable properties, making them easy to design energy conversion devices for use in any place and any time. On the other hand, Solar and Wind energy depend on variables such as daytime or nighttime, season, location, the orientation of the receiving surface as well as the presence or absence of clouds..

[Audio] Solar energy has been around for billions of years and is one of the most abundant sources of energy in the world. On average, 4x10^26 joules of energy is produced by the sun and arrives on earth, where it's intercepted by solar panels. Most of this energy strikes the equator directly, while the rest is diffused across the Northern and Southern hemispheres. This energy is then used to power homes and businesses across ASEAN countries, an effort started in September 2023 spearheaded by SITTINATON MUANCHAONA from the Metropolitan Electricity Authority's Power System Research and Innovation Department. In conclusion, solar energy is a clean and sustainable energy source since its production does not generate any pollution..

[Audio] The sun is the primary source of energy on Earth. This energy can be harvested and utilized within electricity systems, which is known as solar energy. Solar energy is free, clean, and abundant. Electromagnetic waves from the sun are collected by photovoltaic cells, then transformed into electricity which can be used in homes and industries. SITTINAN MUANCHAONA of the Metropolitan Electricity Authority's Power System Research and Innovation Department will oversee a project aiming to introduce photovoltaic systems, modify the MEA grid requirements, and modernize the power distribution system in ASEAN countries from September 4th to 29th, 2023. This project provides a great opportunity for solar energy to contribute to electricity systems..

[Audio] The graph we are looking at shows the spectral distribution of solar radiation at the top of the atmosphere, with the range of wavelengths shown on the x-axis and the amount of power in each wavelength falling on earth in square metre on the y-axis. Most of the energy coming from the sun is in the visible region of the electromagnetic spectrum. In September 2023, SITTINAN MUANCHAONA of the Metropolitan Electricity Authority's Power System Research and Innovation Department will lead the introduction of PV System, MEA Grid Requirement and the modernization of Power Distribution System in ASEAN countries..

[Audio] SITTINAN MUANCHAONA of the Metropolitan Electricity Authority's Power System Research and Innovation Department will lead an important effort from the 4th to 29th of September 2023, focused on the introduction of PV System, MEA Grid Requirement and the modernization of Power Distribution System in ASEAN Countries. Data shows solar insolation in the region is measured at 12 kWh/m2/day, indicating solar energy has great potential for energy production in this region..

[Audio] Solar energy is the main source of energy and the three types of terrestrial solar radiation contribute to the total solar radiation amount that reaches us. Direct radiation is sunlight coming directly from the sun. Diffuse radiation is radiation that has been scattered by the atmosphere and reflected radiation is radiation that has been reflected off the ground or any other surface on earth..

[Audio] Solar radiation significantly impacts the Earth's surface and measuring it is important for a sustainable future. An image showing the changes in solar radiation received on the Earth's surface between September 4 and 29, 2023 is part of SITTINAN MUANCHAONA's modernization project. This data will be used to find which areas of ASEAN countries are most suitable for installing PV systems. The Metropolitan Electricity Authority is working to reduce the dependence on non-renewable sources of energy through renewable energy..

[Audio] We will now look at the definitions of some important terms related to PV Systems, MEA Grid Requirement and modernization of Power Distribution Systems in ASEAN countries. Beam Radiation is solar radiation intercepted by a surface with minimal direction change and reduced scattering in the atmosphere. It is also known as Direct Radiation. Diffuse Radiation is solar radiation scattered by aerosols, dust and does not have a unique direction. Total radiation is the combination of both beam and diffuse radiation and is also known as Global Radiation. Irradiance is the rate at which the radiant, in terms of power, is incident on a unit surface, measured in W/m2. Irradiation is the incident energy per unit area of a surface, found by integration of irradiance over time, measured in Wh/m2, kWh/m2, or J/m2. That concludes this part. Let's move on to the next slide..

[Audio] People in ASEAN countries can look forward to an important period from the 4th to 29th of September 2023. SITTINAN MUANCHAONA from the Power System Research and Innovation Department of the Metropolitan Electricity Authority will introduce PV System, MEA Grid Requirements and a modernized Power Distribution System. The implementation will use various sources such as the Global Solar Atlas, Global Wind Atlas, EnergyDataInfo, Map sites, PV Study, Download, Site Area, Region, Distance, etc. On top of that, Specific Photovoltaic Power Output, Direct Normal Irradiation, Global Horizontal Irradiation, Diffuse Horizontal Irradiation, Global Tilted Irradiation at Optimum Angle, Optimum Tilt of PV Modules, Air Temperature, Terrain Elevation, Reports, OpenStreetMap, Satellite Tiles, Esri, World Bank Group, ESMAP and Contact will all be taken into account..

[Audio] From September 4th to 29th 2023, SITTINAN MUANCHAONA, from the Power System Research and Innovation Department of the Metropolitan Electricity Authority, will endeavor to introduce PV System, MEA Grid Requirement, and modernization of Power Distribution System into ASEAN countries. To do so, they will make use of Global Solar Atlas, Global Wind Atlas, and Energy Data Info to increase the region's PV power output by studying PV systems with a capacity of 100 kWp, and their monthly and yearly PV electricity and solar radiation. Moreover, the World Bank Group has lent their support to this venture..

[Audio] Studies have revealed that Thailand has a high potential for solar energy. The monthly distribution of solar radiation intensity has been investigated and found to be influenced by Northeast and Southwest Monsoons. It was found that most of Thailand receives the highest solar radiation in April and May, ranging from 5.56 to 6.67 kWh/m2.day. The highest solar radiation is located in the northeastern part and some areas of the central region, accounting for 14.3 percent of the country. Additionally, 50 percent of the total areas recorded an annual average of 5.00 to 5.28 kWh/m2.day, which is considered relatively high. This data is important to consider when modernizing the power distribution system in ASEAN countries in September 2023..

[Audio] PV Systems, MEA Grid Requirements and the modernization of Power Distribution Systems are topics of great importance in ASEAN countries currently. This slide explains some of the technologies used to convert solar energy into electricity and the applications in which it can be employed. Solar Thermal Conversion and Solar Cells, also known as Photovoltaic, are among the most popular technologies used to generate energy from the sun. These systems can be used to power different types of applications including buildings, public lighting, etc..

[Audio] From the 4th to the 29th of September 2023, SITTINAN MUANCHAONA of the Metropolitan Electricity Authority's Power System Research and Innovation Department will spearhead a significant milestone for the energy industry in Southeast Asia. This groundbreaking feat will focus on introducing PV systems, MEA Grid Requirements, and modernizing power distribution systems. PV cells, otherwise known as photovoltaic or solar cells, are utilized in a variety of uses ranging from calculators to reservoirs and even space crafts. Invented in the 1950s for US satellites, solar cells have since been successfully used to provide off the grid and grid connected systems with energy. During this month, the governments and businesses of Southeast Asia will strive to guarantee the region with renewable energy in the future..

[Audio] For the period of the fourth to the twenty-ninth of September, 2023, Sittinan Muanchaona of the Metropolitan Electricity Authority's Power System Research and Innovation Department will spearhead the implementation of PV System, MEA Grid Requirements and the modernization of Power Distribution System in ASEAN countries. To properly understand the system, one must consider the amount of sunshine, solar irradiance, temperature, and the number of cells or cell area in the module that are integral components of the system..

[Audio] From fourth to twenty-ninth of September, twenty-twenty-three, Sittinan Muanchaona from the Metropolitan Electricity Authority's Power System Research and Innovation Department will lead a major initiative to introduce a photovoltaic system, the MEA grid requirement, and the modernization of power distribution systems across the ASEAN countries. During this period, attendees will be informed of solar cells arranged together in PV modules, as well as groups of modules being put together in strings and arrays. They will also be taught about the standard size of photovoltaic cells (156mm by 156mm) and the average size of solar panels (typically 1600mm by 1000mm) used in rooftop installs, with most panels weighing around 20kg. This is an occasion to gain knowledge of the photovoltaic system and its components, as well as benefit from the industry experts present..

Generation 1 Generation 4 Generation 2 Generation 3.

[Audio] Solar energy is one of the most advantageous and convenient sources of energy in the ASEAN countries. There are three types of photovoltaic technologies: monocrystalline, polycrystalline and thin-film. Monocrystalline solar panels are the most efficient but also have the highest prices. Polycrystalline and thin-film panels are less efficient and have shorter lifespans compared to monocrystalline panels but are less expensive. From the fourth until the twenty-ninth of September in 2023, SITTINAN MUANCHAONA of the Metropolitan Electricity Authority's Power System Research and Innovation Department will lead a project to introduce photovoltaic systems, modify the power distribution system, and upgrade the MEA grid. This project will be a great step forward in the development and sustainability of renewable energy in the ASEAN region..

[Audio] It is imperative for the MEA Grid Requirements to be met and the modernization of Power Distribution Systems in ASEAN Countries is the means to do this. We have set the goal to accomplish this by the 4th of September 2023 and SITTINAN MUANCHAONA of the Metropolitan Electricity Authority's Power System Research and Innovation Department will be leading the charge. Introducing a well-thought-out PV System is key to the success of modernization and will provide ASEAN Countries with an infrastructure to support a modern, reliable, and efficient power distribution system. We must remain committed to this cause in order for our goal to be achieved. Only with the introduction of the new system will ASEAN Countries be able to protect their investments and ensure their long-term stability. Therefore, let us join forces to guarantee that the goal is met by the 4th of September 2023..

[Audio] As we move closer to September 2023, the ASEAN countries are on the cusp of a landmark transition as SITTINAN MUANCHAONA, from the Metropolitan Electricity Authority's Power System Research and Innovation Department, introduces PV System, MEA Grid Requirement and the modernization of Power Distribution System. These PV systems provide clean and renewable energy, harnessing the power of the sun to generate electricity. It is important to be aware of the watt peak, which is a measure of the output power of the solar module, as this will affect the power production of the system. With the proper knowledge and understanding of these various components and requirements, the ASEAN countries can effectively use these PV systems to help improve energy access and reduce their reliance on other sources..

[Audio] The graph illustrates the I-V curve, demonstrating the correlation between current and voltage in a component, commonly a solar cell. It is noticeable that when the voltage rises, so too does the current, and eventually the current reaches a maximum point - the maximum power point of the system..

[Audio] Understanding the current-voltage properties of solar cells, known as the I-V Curve, is important in order to monitor and manage the output of the cells. In September 2023, SITTINAN MUANCHAONA of the Metropolitan Electricity Authority's Power System Research and Innovation Department will be leading the introduction of photovoltaic systems in ASEAN countries. This will help to modernize the power distribution system in the region and bring benefit to the people..

[Audio] Solar power is gaining more and more recognition as an invaluable energy source. For furthering our knowledge of the science behind it, I-V curves must be examined. They are affected by temperature of the cell and the amount of sunlight the cell is exposed to. With regards to crystalline PV systems, when the cell temperature increases, the voltage and power of the system decreases, while the current output is slightly increased. This information is essential when considering the introduction of PV systems, as well as how MEA Grid Requirements and power distribution systems in ASEAN countries should be modernized - a task taken up by Sittinan Muanchaona from the Metropolitan Electricity Authority's Power System Research and Innovation Department..

[Audio] When examining photovoltaic systems, it is important to consider the temperature and efficiency levels. As temperatures increase, so does the decrease in efficiency. Therefore, an efficient cooling system for the modules should be implemented to ensure that efficiency does not drop. This can be achieved by ventilation, or other methods. Furthermore, it is critical to be aware of the I-V curve for photovoltaic systems, which affects the system performance and efficiency..

[Audio] Providing a reliable electrical power supply in ASEAN countries is increasingly complex due to the influx of solar PV systems. From September 4th to 29th 2023, SITTINAN MUANCHAONA, from the Metropolitan Electricity Authority's Power System Research and Innovation Department, will lead a project to modernize power distribution systems. One of the project's main focuses is to address the issue of shading of solar PV cells and its effect on the system's power output. While solar PV cells come with differing capabilities, cells that are shaded typically produce much less power than those that are not. In most cases, the highest voltage strings that are unshaded provide the bulk of the power, while strings that are shaded provide very little..

[Audio] ASEAN countries are modernizing their power distribution systems with the introduction of PV systems. From 4th to 29th September 2023, SITTINAN MUANCHAONA from the Metropolitan Electricity Authority's Power System Research and Innovation Department will take the lead. Standard 60 cell PV modules, protected by bypass diodes, will be used. The modules are composed of 3 substrings, with each substring producing an approximate voltage of 0.5V when exposed to uniform solar light. Additionally, solar PV cell shading will be taken into account..

[Audio] Between the 4th and 29th of September 2023, SITTINAN MUANCHAONA from the Metropolitan Electricity Authority's Power System Research and Innovation Department is heading a modernization process and the introduction of PV System and MEA Grid Requirements in ASEAN countries. In regard to the solar photovoltaic systems' power output, many factors come in play such as the string length, the number of modules connected to an inverter, the amount of light received by the cells and the use of bypass diodes. As an example, if a string of 10 modules is connected to an inverter and one of the cells receives less light, the centralized inverter can utilize a bypass diode and reach a power output of 98% of the full power or it can choose not to use one and get 80% of the full power. On the other hand, in the case of an individual MPPT system, the power output will be 98% of the full power. Overall, the Metropolitan Electricity Authority's Power System Research and Innovation Department is devoted to a successful modernization process of ASEAN countries' power distribution system, allowing for greater energy efficiency and cost-effectiveness..

[Audio] Without greetings, beginning with Today, and without thanks: As part of the introduction of PV systems, MEA Grid Requirements and the modernization of Power Distribution Systems in ASEAN countries led by SITTINAN MUANCHAONA, some information about Connection Point and Installed Capacity regulations must be mentioned. Single-phase connected DG must not exceed 5 kW, multiple single-phase connected DGs must be distributed equally in the three-phase system, and the maximum difference in installed capacity between each phase should not be more than 5 kW. For 12 or 24 kV feeders, the total capacity of DGs must not exceed 4 MW or 8 MW respectively, and the total capacity of DGs connected to the same transformer must not exceed 15% or 20%, respectively, of the transformer’s capacity. If these regulations are not met, then the DGs must be connected to the High Voltage system at 69/115kV. Lastly, for Very Small Power Producers, they have to sell power to the grid..

[Audio] For the 4th to the 29th of September 2023, a focus is placed on introducing PV Systems, MEA Grid Requirements and modernizing the Power Distribution System in ASEAN countries. To guarantee the system is dependable and secure, connection points, installed capacity regulations and communication systems must be set up. Direct Inward Dialing, Fixed Radio, and Fibre Optic systems must be linked with the SCADA system, and certain circumstances may need a Zero Export Controller and Reverse Power Relay, as well as a Power Quality Meter or Remote Terminal Unit. These precautions help to make sure the successful and reliable running of the power system..

[Audio] The Metropolitan Electricity Authority, through its Power System Research and Innovation Department, will be leading a project from the 4th to the 29th of September 2023 in ASEAN countries to promote the introduction of PV systems, the MEA grid requirements, and the modernization of the power distribution system.

A link at the bottom of the slide provides the list of approved inverters..

[Audio] I would like to discuss an exciting and revolutionary project which is taking place in the ASEAN countries in 2023. SITTINAN MUANCHAONA, from the Metropolitan Electricity Authority's Power System Research and Innovation Department, is leading the project which is devoted to the introduction of PV System, MEA Grid Requirement and the modernization of Power Distribution System. This project is aiming to improve the efficiency and safety of the power system of these countries through the implementation of Islanding Protection and Grid-connected Inverter Regulation. It is undoubtedly anticipated that this inspiring initiative will have a positive and long-lasting impact in the ASEAN countries for many years to come..

[Audio] We are going to talk about the protection devices used to ensure safe and reliable operations of a PV system. The reverse power relay is used to disconnect the grid when reverse power flow is detected. The zero export controller adjusts the produced power from solar when available power is more than the internal load power, avoiding reverse power flows. Grid-connected inverter regulation is a vital part of a sound power system, with details provided in slide 47. These protection devices are essential for SITTINAN MUANCHAONA of the Metropolitan Electricity Authority's Power System Research and Innovation Department's goal of modernizing ASEAN countries' power distribution system..
