摘　　要：分布式电池的大规模随机无序接入给电网运行安全带来了新挑战。为了充分刻画分布式电池无序充电对电网运行的影响,文章基于正态分布和Weibull数学分布,建立了日行驶里程与最后一次出行结束时刻的分布式电池充电概率分布模型,并以算例仿真验证了所建模型的有效性和可行性。Large-scale random and disorderly access of distributed batteries brings new challenges to the security of power grid operation.In order to fully characterize the impact of disorderly charging of distributed batteries on power grid operation,based on the normal distribution and Weibull mathematical distribution,a distributed battery charging probability distribution model was established for the daily driving mileage and the end of the last trip.Numerical cases were tested to demonstrate the effectiveness and feasibility of the proposed model.
