摘　　要：针对光伏、风机等具有不受控性和波动性的分布式发电系统(DGS)大规模并入电网造成的储能单元出力不均匀和荷电状态(SOC)不均衡的问题,基于多代理系统提出了一种基于梯度补偿的改进型一致性算法。将DGS、退役动力电池储能系统(DPBESS)和电网共同组建成多代理微电网系统。在改进一致性算法基础上设计了SOC均衡控制方法,加快了无中心控制器的储能系统SOC均衡速度,保证了微电网内能量的供需平衡。通过仿真验证了所提控制方法的有效性。For the problem of uneven power output and unbalanced state of charge(SOC)of energy storage units caused by large-scale integration of distributed generation systems(DGS),such as photovoltaic and wind turbine,into the grid,an improved consistency algorithm based on gradient compensation was proposed based on a multi-agent system.The DGS,decommissioned power battery energy storage system(DPBESS)and the grid were jointly formed into a multi-agent microgrid system.The SOC equalization control method was designed based on the improved consistency algorithm,which speed up the SOC equalization of the energy storage system without central controller and ensured the balance of energy supply and demand in the microgrid.The effectiveness of the proposed control method was verified by simulation.
