摘要：
A power supply capability analysis method of the DC distribution network is proposed. With N-1 as the boundary condition for system operation, the power supply capacity of the DC distribution system is analyzed by considering the power supply capacity of the converter station and the power supply transfer capacity of the grid. On the basis of this analysis method, the influence of the access of the integrated photovoltaic-storage power station on the power supply capacity of the DC distribution network is studied. Then, it is studied how the energy storage capacity can be configured within a photovoltaic power station and among multiple photovoltaic power stations to maximize the power supply capacity of the DC distribution network. Finally, the validity of the analysis method in this paper is verified by the calculation of a DC distribution network topology case, and the simulation provides a theoretical basis for the planning and design of the DC distribution network with integrated photovoltaic-storage power stations.
