project introduction:
as the core infrastructure for energy flexibility and efficient spatiotemporal translation, battery energy storage plays an irreplaceable role in the current global energy low-carbon transformation revolution, with a huge application scale and continuous rapid development. however, large-scale battery energy storage systems have long faced problems such as massive differentiated battery management, coordinated control, and safe operation, which are essentially due to the shortcomings brought about by the fixed series-parallel battery grouping structure. through information-energy integration technology and innovative module technology, innovating the battery grouping mode and energy control mechanism is an important way to solve the above problems. in view of the pain points such as the efficiency, safety, economy, and compatibility of the battery fixed series-parallel grouping method, the project plans to innovate the energy informatization processing mechanism to eliminate the shortcomings of the battery energy storage system, elucidate the coupling laws of the intrinsic properties and operation characteristics of the dynamic reconfigurable battery energy storage system, propose intrinsic safe energy control methods, overcome a series of key technologies such as efficient system integration, optimized operation, and intelligent operation and maintenance, develop hundred-megawatt-hour dynamic reconfigurable battery energy storage system equipment, construct demonstration projects of hundred-megawatt-hour dynamic reconfigurable battery energy storage systems on the power supply side, grid side, and user side, and complete application verification and comprehensive performance evaluation.
