Project Introduction：

As the core infrastructure for flexible and efficient space-time translation of energy, battery energy storage plays an irreplaceable role in the current global energy low-carbon transformation revolution. Its application scale is huge and continues to develop rapidly. However, large-scale battery energy storage systems have long been faced with problems such as massive differentiated battery management, coordinated control and safe operation. The fundamental reason is the short board effect brought about by the fixed series-parallel battery grouping structure. Through information-energy cross-fusion technology and innovative module technology, the innovation of battery grouping mode and energy control mechanism is an important way to solve the above problems. In view of the pain points of energy storage system efficiency, safety, economy, and compatibility caused by the fixed series-parallel grouping of batteries, the project intends to innovate the energy information processing mechanism that essentially eliminates the short board effect of battery energy storage system, clarify the coupling law of the intrinsic properties and operating characteristics of the dynamic reconfigurable battery energy storage system, propose an intrinsically safe energy control method, overcome a series of key technologies such as efficient system integration, optimized operation, and intelligent operation and maintenance, develop 100MWh dynamically reconfigurable battery energy storage system equipment, build 100MWh dynamically reconfigurable battery energy storage system demonstration projects on the power supply side, grid side and user side, and complete application verification and comprehensive performance evaluation.
