| Abstract | Power grid code can differ according to the type of electricity generation technology and the type of connection used when power generation conditions vary. The power grid code has been in effect in member states of the European Union for a long time when it comes to variable renewable energy. One of the nations with extremely high goals for grid integration of renewable energy is Germany, for instance. Germany is prepared for grid coding and intends to produce between 40 and 45 percent of renewable energy by 2025. Furthermore, the Nordic grid code is robust, and Denmark, one of the EU members, has used renewable energy significantly since 1985. In addition, Thailand's grid code was first established in 1994 and has since undergone three changes, the most recent of which was in 2019. Within the Association of Southeast Asian Nations (ASEAN), Thailand has the greatest prevalence of VRE. Technically, Thailand's power grid is flexible enough to incorporate up to 0.15% of VRE by 2030. (19GW solar, 6GW wind). In Germany, Denmark, and Thailand, the grid codes for VRE integration are reliable. The lack of suitable grid code, technical rules, and documentation, however, has resulted in a relatively low degree of VRE integration in Cambodia at the moment. Cambodia needs to integrate more VRE, however the country's grid coding standard is unsatisfactory. Technical requirements for VRE integration are also present in Cambodia. Therefore, we must research how to increase VRE from the best worldwide experiences countries. An overview of the technical grid code requirements for VRE integration into the electricity system is given in this paper. This study focuses on the key technical specifications for VRE power plants that are present in the majority of grid codes, including active and reactive power regulation, voltage and frequency operating limitations, frequency control, power quality, and fault ride-through capabilities. Cambodia could adopt VRE integration based on other nations' grid code development after researching the finest worldwide experiences with technical grid code needs. |
