摘　　要：针对由光伏电池、储能电池和负载组成的孤岛模式下的直流微电网中,光伏发电单元因为自身易受外界环境影响会出现微电网功率不平衡,而传统的微电网协调控制策略使得储能电池电能质量波动较大,导致其协调控制模式切换的频率较高,为此提出采用非对称模糊控制策略跟踪最大功率点,充分利用光能,同时将直流微电网母线电压进行分段式协调控制,使得系统间协同效率较高。最终通过Matlab/Simulink建模仿真,验证所提协调控制策略的可行性与有效性。In the islanded mode of micro grid composed by photovoltaic battery,storage battery and DC load,photovoltaic power generation unit itself is easily affected by the environment,so there will be micro grid power imbalance,while the traditional coordinated control strategy of micro grid energy storage battery which makes the power quality fluctuation,causes higher frequency coordination control mode switch. The asymmetric fuzzy control strategy of maximum power point tracking was proposed to make full use of solar energy,while the DC micro grid voltage busbar sectional coordination control was proposed to make higher the efficiency of collaborative systems. After the modeling and simulationofMatlab/Simulink,the feasibility and effectiveness of the proposed coordinated control strategy were verified.
