摘　　要：使用可再生能源可大大减少发电的燃料消耗,从而减少温室气体的排放。由分布式电源、储能装置、能量转换装置、负荷、监控和保护装置等组成的小型发配电系统又称为微电网,它和智能电网的概念是从可再生能源的发电厂的部署演变而来的,它们融入了现有的公用事业电网。本文对单机直流微电网进行了仿真分析,太阳能光伏系统是电网的主要来源,蓄电池作为储能系统。在MATLAB/Simulink中建立了直流微电网的仿真模型。对所设计的系统在各种输入条件和负载变化下进行仿真,研究和分析整个系统的性能,给出并讨论了直流微电网各阶段不同工况下的仿真结果。The use of renewable energy can greatly reduce the fuel consumption of electricity generation and thus reduce greenhouse gas emissions.Microgrid is a small power generation and distribution system composed of distributed power sources,energy storage devices,energy conversion devices,loads,monitoring and protection devices,etc.It and the concept of smart grids are evolved from the deployment of renewable energy power plants.Both have been applied to the existing utility grid.In this paper,the simulation analysis of single DC microgrid is carried out.The Solar Photovoltaic System is the main source of the power grid,and the battery is the Energy Storage System.The simulation model of DC microgrid is established in MATLAB/Simulink.The system is simulated under various input conditions and load changes,the performance of the whole system is studied and analyzed,and the simulation results under different working conditions at different stages of DC microgrid are given and discussed.
