中文摘要：
由小容量分布式电源、储能装置和负荷组成的低压微电网,因供电方式灵活及可充分利用各种可再生能源等优点.越来越受到人们的重视.但由于微电网容量小,且大量采用电力电子装置实现组网,其运行更易受到谐波的影响.分析低压微电网中谐波的主要来源,即微电网自身的非线性负荷产生的谐波、微电源电力电子接口产生的谐波和配电网的谐波渗透,阐述其影响及微电网与传统大电网的不同之处.介绍微电网的运行方式和并网控制策略,并通过仿真分析非线性负载和配电网侧谐波电压渗透对微电网正常运行的影响.
英文摘要：
Because of advantages of flexible power supply modes, maximum utilization of varieties of renewable energy sources and so on, people pay more and more attention to LV microgrids composed by distributed energy sources, energy, storage devices and loads. For the reason that capacities of most microgrids are small and power electronic interfaces are used between micro-sources and microgrids, microgrid operation is more easily affected by harmonics. The main sources of halxnonics in microgrids were analyzed, which included non-linear loads of microgrids, power electronic interfaces of micro sources and harmonics penetration from distribution system. The operation modes and control strategies for synchronization of microgrids were introduced. Simulation results show that the operation of mierogrids is influenced by nonlinear load and harmonics penetrated from distribution system.
