摘　　要：研究了以光伏组件为主体的分布式发电系统的汇流并网结构。主要包括:实现光伏电池工程模型、电导增量法的MPPT方法,基于电网电压定向的矢量控制并网方法和最大功率点的热斑效应;研究微电网控制中常用的PQ控制策略、V/f控制策略,用Simulink实现仿真;仿真分析了主要的几种光伏汇流系统的结构:直流模块式结构、交流模块式结构,并在Simulink上对它们的性能进行测试,验证其可行性。This paper studied the structure of parallel operation of distributed generation systems with PV as the main part. The main aspects of the work are as follows： The engineering model of photovohaic cells, the incremental conductance MPPT method, the grid voltage oriented vector control parallel method and the hot spot effect of the maximum power point; The PQ control strategy, the V/f control strategy used in micro-grid control implemented by Simulink simulation; The simulation analysis of the main structure of the confluence of several photovohaic systems： DC modular structure, AC module structure, and the test for their performance in Simulink, to verify its feasibility.
