China's Electric Power Research Institute took a breakthrough in the renewable energy microgrid control technology project On May 22nd, China National Electric Power Research Institute Co., Ltd. took the lead to undertake the key technology and application of high-reliability power supply operation control of renewable energy microgrids through the technical appraisal organized by the Chinese Society for Electrical Engineering. At present, a large number of demonstration projects for renewable energy microgrids have been built at home and abroad, which has become an important way to solve technical difficulties in remote areas and islands. The renewable energy microgrid system is dominated by new energy sources. The proportion of power electronic devices is high, there is no system inertia or system inertia is small, and the construction process is faced with poor scalability, weak anti-interference ability, difficulty in dispatch control, and difficulties in operation and maintenance. Other issues hinder the development of renewable energy microgrids. China National Electric Power Research Institute, Jiangsu University of Science and Technology, Southeast University, and other organizations, focused on building a renewable, energy-efficient, dispatchable, and easily maintainable renewable energy microgrid power supply system to develop key technologies for high-reliability power supply operation control Develop energy storage converters that can be expanded in parallel to support multi-source networks to solve the problems of large-scale microgrid and multi-type power supply networking. The maximum capacity of microgrids has been increased from hundreds of kilowatts to several tens of megawatts, making renewable energy The power supply radius of the micro-grid is extended to several tens of kilometers; an intelligent, integrated, modular optical storage integrated machine is developed, which greatly improves the micro-grid's power supply immunity and reliability, and realizes the high-quality power supply of the renewable energy microgrid. Carry out research on multi-time scale power and energy combined optimization dispatching technology for renewable energy microgrid systems to achieve multi-temporal multi-objective optimization scheduling and control of renewable energy microgrid systems in multiple time scales; develop panoramic visualization monitoring and maintenance of renewable energy microgrid systems The management platform realizes panoramic monitoring, remote diagnosis and early warning analysis of the renewable energy microgrid system. The project's achievements have been popularized and applied in micro-grid demonstration projects in different scenes in industrial and mining enterprises, non-electric regions, islands, etc., and exported to India, Pakistan, Cambodia, and other countries, to promote micro-grid system equipment upgrades and industrial scientific and technological progress, to provide micro-grid development Technical support.
