摘要
为推动35 kV高压直挂电池储能系统(battery energy storage system,BESS)的实际应用,系统研究了35 kV高压直挂BESS的主电路参数设计、控制策略及相关控制参数的设计方法;并在MATLAB/Simulink中搭建了35 kV/10 MW/10 MWh系统的仿真模型,以验证所提设计方法及控制策略的正确性。研究结果表明:35 kV高压直挂BESS单机容量大,功率响应速度快,可对内部电池簇进行主动荷电状态均衡及故障冗余控制,系统效率和可靠性更高,能适应未来新能源大规模发展需求。
The design method of main circuit parameters,related control parameters and control strategy are systemati-cally studied in order to promote practical application of 35 kV high-voltage large-capacity battery energy storage system(BESS).A simulation model of the 35 kV/10 MW/10 MWh system is built in MATLAB/Simulink to verify the correct-ness of the proposed design method and control strategy.The research results show that the 35 kV high-voltage BESS has large unit capacity and fast power response and can implement active state-of-charge balance and fault redundancy con-trol of internal battery clusters.Its system efficiency and reliability are higher,which can adapt to the large-scale development of renewable energy in the future.
