摘要
为了提高储能系统功率分配的合理性,提高风力、光伏电站及微网运行的经济性和稳定性,针对大容量全钒液流电池储能系统提出了一种多目标优化功率分配策略。该策略将储能系统的运行损耗、储能单元的充放电容量折损及储能单元间的荷电状态均衡度作为多目标优化模型,构建系统目标函数,利用模拟退火粒子群算法实现储能系统的经济性和可调度性运行。所提策略以MATLAB/Simulink为仿真平台,搭建了多组并联结构的全钒液流电池模型,并进行功率分配仿真验证,研究结果表明:所提策略可有效降低系统的运行损耗和储能单元的容量折损率,且储能系统可达到一致性均衡。研究结果可为储能系统功率分配提供参考。
In order to improve the rationality of power distribution in energy storage system and improve the operational stability and economy of wind farm,photovoltaic power stations and micro-grid,we proposed a power distribution strategy based on multi-objective optimization of vanadium redox battery(VRB)energy storage systems for large-scale energy storage system.The operation loss of the energy storage system,capacity loss of the energy storage unit during charge and discharge stage,and the equilibrium degree of state-of-charge(SOC)between the energy storage units were taken as parameters of the multi-objective optimization model in the strategy,the system objective function was constructed,and the economic and schedulable operation of energy storage system was realized by using the simulated anneal-particle swarm optimization(SAPSO)algorithm.Then,the multi-parallel structure of VRBs models were built on the MATLAB/Simulink for the power distribution simulation verification.The research results prove that the proposed strategy can significantly reduce the system operation loss and the capacity loss rate with a consistent balance,and the research can provide a reference for power distribution of energy storage system.
