摘要
储能可以平滑分布式电源出力的波动性,挖掘其提升配电系统供电可靠性的潜力。为了定量评估储能装置的这种效果,提出了一种含分布式风机、光伏阵列和蓄电池的配电系统准序贯蒙特卡洛可靠性评估方法。在建立了风光蓄元件的时序模型和状态转移模型的基础上,对系统中的非电源元件进行序贯抽样,而对风光蓄元件进行非序贯抽样。讨论了含风光蓄配电系统的故障效果影响分析过程,给出了相应的可靠性评估流程。以改造的IEEE RBTS系统为例,对不同情境下的系统可靠性水平进行了对比分析,验证了所述方法的有效性。
Energy storage can smooth out the output power fluctuation of distributed generations and potentially improve the supply reliability of distribution system.To quantitatively assess the effect of energy storage,this paper proposes a pseudo-sequential Monte Carlo simulation method for reliability evaluation of distribution system including distributed wind turbines,photovoltaic arrays and batteries.The hourly sequential models and state variation models of wind turbines,photovoltaic arrays and batteries are established.On this basis,the non-power components are sampled sequentially and the components of wind turbines,photovoltaic arrays and batteries are sampled non-sequentially.The failure modes and effects analysis procedure of distribution system is discussed and the reliability evaluation flow is illustrated.Taking the modified IEEE RBTS as an example,system reliability indices in different situations are compared and analyzed,and the effectiveness of the proposed method is verified.
