摘　　要：作为消纳新能源发电的一种手段,微电网以其灵活性和经济性,日益受到各国重视。为了研究微电网的运行特性,文中首先研究各分布式电源数学模型,并基于MATLAB/Simulink仿真系统,分别搭建光伏、蓄电池储能系统、柴油发电机的仿真模型,结合系统自带模块,构建了交流微电网的整体性仿真模型。对该系统在多种工况下,各分布式电源出力对系统运行特性的影响进行仿真试验,结果表明,文中所建的交流微电网模型能够准确模拟系统的实际运行情况,为微电网的运行与规划提供了技术支持。To investigate the operation characteristics of the microgrid, mathematical models of photovoltaic system, energy storage system, and diesel generator are established based on the simulation software MATLAB/Simulink. Further, a complete model of microgrid system is built with the modules in MATLAB/Simulink. The microgrid system is simulated to reveal the effect of distributed power output on its operation characteristics in different operation conditions. Simulation shows that the proposed model of microgrid system accurately reflects the state of real microgrid system, and may provide a technical support for the microgrid planning and operation.
