Distributed Energy Storage System Siting and Sizing Method Considering Photovoltaic Hosting Capacity Enhancement

The large-scale integration of renewable energy sources has imposed more stringent requirements on the hosting capacity of distribution networks. This paper proposes a distributed energy storage siting and sizing method considering the enhancement in photovoltaic hosting capacity. The method comprehensively considers the operational state of the distribution network and the increased PV hosting capacity following the integration of distributed energy storage. The distributed energy storage planning model is established to determine the optimal DESS planning scheme and enhance the PV hosting capacity of distribution networks. Finally, the effectiveness of the proposed method is verified based on a modified IEEE 33-bus test case. Results show that the proposed method can maximize the PV hosting capacity of distribution networks while ensuring economic benefits and security.
