Abstract
The unconstrained access of distributed photovoltaic or the extensive use of distributed photovoltaic grid connection leads to the change of system power flow and voltage distribution, voltage out-of-limit, and other problems. In this paper, the relationship between the distributed photovoltaic capacity ratio and the output power of the inverter AC side is analyzed. Considering the constraints between energy storage and distributed photovoltaic capacity, the energy storage control strategy is proposed. Then, the distribution photovoltaic consumption constraints, the line limit transmission capacity constraint, and voltage constraint are considered. The objective function of the maximum capacity of configurable distributed photovoltaic capacity on the inverter DC side is established. The calculation method of access capacity of distributed photovoltaic considering the capacity ratio is proposed. Finally, a distribution network example is given to verify the effectiveness and adaptability of the proposed method.
