A Coordinated Control Strategy of Microgrid Based on PV，BES and SC

摘要:

针对光伏系统的不足，利用蓄电池 － 超级电容对光伏发电系统出力的互补特性，构成蓄电池 － 超级电容和光 伏发电的微电网系统，并提出采用基于直流母线电压平衡的控制策略实现蓄电池 － 超级电容的快速响应。基于 Matlab /Simulink 搭建微电网模型，仿真验证了控制策略的优越性和正确性。

Abstract:

For the shorts of the output of photovoltaic power generation system，the complementary characteristics of battery and supercapacitor energy storage system to photovoltaic power generation system is utilized to composed the microgrid system with photovoltaic power generation，battery and supercapacitor． A control strategy based on DC bus voltage balance is proposed to achieve the fast response of battery and supercapacitor． Finally，the simulation model of microgrid is established with Matlab /Simulink simulation software，and the simulation results verify the superiority and validity of the proposed control strategy．
