| 摘 要： | 采用序贯蒙特卡洛模拟方法,分析了含单相光伏和三相光伏并网系统的不对称辐射形配电网的三相随机潮流计算。其中,考虑了天气的随机变化,对太阳能辐射进行逐时模拟,计及了光伏阵列效率的逐时变化、光伏阵列的有效光照面积、最大功率点跟踪和逆变器效率及整个光伏发电系统的可靠性等,对并网光伏发电系统输出进行逐时随机模拟。采用时变负荷模型并计及其随机性,编制了含光伏并网系统的配电网三相随机潮流计算程序。实际算例验证了所述方法的可行性和实用性。

| Abstract: | A method of three-phase probabilistic power flow for distribution systems with single-phase and three-phase grid-connected photovoltaic(PV) systems is introduced using sequential Monte Carlo techniques.The hourly output power of PV system is simulated considering solar irradiance,random change of weather,efficiency and effective sunlight area of PV arrays,efficiency of maximum power point tracking(MPPT) and inverter,and the reliability of overall PV system.The time-varying load model with randomness is incorporated in the probabilistic power flow and a program is developed.Case studies verify the feasibility and applicability of the method. |
