摘　　要：随着分布式电源的逐渐发展,愈来愈多的分布式电源接入电网中,在给电网带来机遇的同时也带来了一定的挑战。风机、光伏等分布式电源受周围环境的影响较大,当其接入配电网后,会给配电网带来一定的影响。为此,本文首先介绍了分布式电源的类型,然后阐述了前推回代潮流计算法的计算原理,最后通过算例分析了分布式电源功率及接入位置对配电网电压的影响,为后续分布式电源并网研究奠定了基础。With the gradual development of distributed generation,more and more distributed generation are connected to the power grid,which brings opportunities and challenges to the power grid.Distributed power supply,such as wind turbine and photovoltaic,is greatly affected by the surrounding environment.When it is connected to the distribution network,it will bring certain impact to the distribution network.Therefore,this paper first introduces the types of distributed generation,then expounds the calculation principle of forward backward power flow calculation method,and finally analyzes and calculates the influence of distributed generation power and access location on distribution network voltage through calculation example,it lays a foundation for the research of distributed generation grid connection.
