本文介绍了光伏 (PV) 分布式发电 (DG) 设计的概率方法及其对低压 (LV) 馈线的影响。采用蒙特卡罗模拟来预测太阳辐射和负荷，并采用精确的方法来求解潮流。该方法在两个研究案例上进行了测试，并将结果与​​基于常用场景的确定性方法的结果进行了比较。事实证明，概率方法对于根据技术限制和不同目标获得最佳光伏评级是必要的，包括在需要时接受合理的风险。结果还表明，在实际情况下，PV-DG 最有可能改善电压分布并降低低压馈线的损耗
This paper presents the probabilistic approach to the design of photovoltaic (PV) distributed generation (DG) and its impact on low voltage (LV) feeder. Monte Carlo simulation is used to predict solar radiation and load, and an exact method is used to solve the power flow. The method is tested on two study cases, and the results are compared with those from deterministic approach based on commonly used scenarios. The probabilistic approach is shown necessary to obtain the optimum PV rating based on technical constraints and different objectives, including accepting a reasonable risk when needed. The results also indicate that PV-DG in a realistic case will most probably improve the voltage profile and decrease the losses on LV feeders
