考虑用户负荷类型的含分布式电源的配电网可靠性评估

Reliability evaluation of distribution network with distributed generation considering customer sectors

该文以含分布式电源的配电网可靠性评估为主要内容,首先研究居民、商业、工业的日负荷特性,建立反映用户用电特性的时序负荷模型。根据分布式电源的出力和负荷需求,建立储能协调运行模型。在此基础上,研究分布式电源的接入以及不同分布式电源出力对各类用户负荷可靠性的影响。最后,基于时序蒙特卡洛模拟算法,对IEEE RBTS BUS6-F1馈线改进系统进行可靠性计算。算例结果表明,分布式电源的接入能有效提高配电网可靠性,且分布式电源对于不同的用户负荷可靠性影响不同。

In this paper,the reliability of distribution network with distributed generation(DG)under different customer sectors is evaluated.First of all,the daily load characteristics of residents,business and industry are studied.A time series load model is established to reflect customer sectors characteristics.The model of the coordinated operation of the energy storage is established through the output of DG and load demand.Finally,based on the sequential Monte-carlo simulation algorithm,the reliability of the IEEE RBTS BUS6 feeder one system is calculated.The results show that the access of DG can effectively improve the reliability of distribution network.The same output of DG has different effects on the reliability of different customer sectors.
