[0002] A multi-energy intelligent power distribution system is a smart power system that integrates advanced information and communication technologies, control technologies, and energy technologies. It is based on a robust grid structure, supported by an information platform, and utilizes intelligent control. It enables optimized resource allocation and effectively supports the large-scale development and utilization of renewable energy, as well as the "plug-and-play" functionality of various energy-consuming facilities. Currently, the State Grid Corporation of China has established comprehensive demonstration zones for first-class multi-energy intelligent power distribution systems in cities such as Xiong'an New Area, Tongzhou District of Beijing, and Nanjing, Jiangsu Province. The large-scale integration of distributed generation (DG), the flexible and adaptable network structure, the aggregation of highly sensitive loads, and the optimized allocation and efficient utilization of integrated energy sources present new challenges to the refined analysis and coordinated control of power generation, grid, load, and storage; real-time monitoring of power equipment operating status; and power supply security and reliability.

[0003] Against the backdrop of the construction and development of intelligent power distribution systems incorporating multiple energy sources, the primary challenges facing the development of such systems are: how to verify the effectiveness and rationality of planning and construction schemes; how to validate the applicability and effectiveness of advanced intelligent control equipment and advanced operation control technologies; and how to verify the rationality and practicality of coordinated optimization scheduling schemes for power generation, grid, load, and storage. There is an urgent need to construct a comprehensive experimental platform for energy generation, management, optimization, coordinated control, and real-time monitoring of intelligent power distribution systems incorporating multiple energy sources, possessing stability, compatibility, and scalability. This platform would provide a digital-in-the-loop simulation and practical verification platform for the verification of new theories, the application of new technologies, and the research and development of new products in intelligent power distribution systems incorporating multiple energy sources.
