摘要 本文针对整县分布式光伏建设导致的配电网投资规模剧增、电网调峰和调压困难的问题展开研究,基于规划分布式光伏装机规模与县域电网负荷匹配度,提出综合考虑消纳与电网调节能力的储能配置策略,一方面解决配电网超承载能力的问题,另一方面缓解调峰压力并抑制分布式光伏反送导致的过电压问题。最后,通过案例验证了方法的有效性,为整县分布式光伏规划和有源配电网调节能力建设提供参考。

Abstract:To solve the increasing gird investment, difficulties in peak load regulation and gird voltage regulation caused by distributed photovoltaic (DPV) construction in county, an energy storage allocation strategy that comprehensively considers the consumption and grid regulation capacity is proposed based on the planned distributed photovoltaic installed capacity and the load matching degree. The proposed method solves the problem of overload capacity of distribution gird. On the other hand, it relieves the pressure of peak load regulation and suppresses the overvoltage caused by power flow reversal. Finally, the validity of the method is verified through a case, which provides reference for the DPV planning of the county and the adjustment capacity building of the active distribution gird.
