摘　　要：文中提出引入适量的光伏发电满足直流微电网对分布式新能源接入的需求,针对光伏发电规模化接入相应的直流微电网建立了仿真模型,并对该直流电网的储能系统和负荷的综合运行概况以及接入现有配电网的影响进行了仿真分析。仿真结果显示文中所模拟的含有光伏接入的直流微电网系统可以满足相当范围内负荷变化的需求,降低了直流电网对输配电容量的要求。该直流电网系统可以自给自足,孤岛运行,同时也能稳定并网,对现有配电网不造成较大的波动。In this paper,it is proposed that the right amount of photovoltaic power generation can meet the demand of DC microgrid for the distribution of new energy sources,the simulation model is established for the photovoltaic power generation to access the corresponding DC microgrid,and the simulation analysis of the energy storage system of the DC power grid and the general operation of the load and the influence on the access to the existing distribution network are carried out.The simulation results show that the DC micro grid system with PV access can meet the demand of load change within a considerable range,which reduces the requirement of DC transmission network for transmission and distribution capacity.The DC power system can be self-sufficient and isolated operated.At the same time,it can also stabilize the grid,the existing distribution network does not cause greater fluctuations.
