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.
