摘要：
The access of photovoltaic (PV) power to the distribution network will affect the power flow and voltage distribution of the distribution network. A large number of PV accesses may cause the voltage fluctuation or even the voltage exceeding, which will affect the safety and operation reliability of the power grid. In view of the voltage exceeding caused by PV access, the influence of energy storage system on PV capacity in distribution network is studied in this paper. First, a distributed PV consumption model is established based on the constraints of voltage and power flow. Secondly, the influence of adding energy storage system on the capacity of distributed PV is analyzed. Finally, the maximum PV access capacity before and after adding energy storage is solved by trial method. Taking IEEE 30 node distribution system as a simulation example, the reasons for limiting the increase of PV capacity of each node are analyzed. The simulation results show that the energy storage system can effectively improve the capacity of distributed PV and avoid the occurrence of voltage exceeding.
