摘　　要：引入分流系数矩阵,用于推导得到少环配电网扩容成本的计算方法。目标函数综合考虑DG接入带来的电量、扩容成本和网损效益,在约束条件中限制环保型DG接入的容量比例,建立考虑风-光-负荷时序相关性的DG规划模型。运用考虑相关性的变区间改进拉丁超立方采样法和粒子群算法求解DG规划模型。通过算例结果对比,验证运用变区间改进拉丁超立方采样法进行模型求解以及DG规划的合理性和有效性。The calculation method of expansion cost for the weakly meshed distribution network was derived by introducing the shunt coefficient matrix. The electricity energy, expansion cost and power loss produced by DG integration were considered by the objective function and the capacity proportion of environment-friendly DG integration was required in the constraints. Based on the above analysis, a DG programming model in view of time series correlation of wind-light-load was established. The Improved Latin hypercube sampling method taking into account intervals of correlation （CI-LHS） and the particle swarm optimization algorithm were utilized to solve programming model. Compared to different scenarios, the rationality and validity of the model for DG planning of CI-LHS were demonstrated. changing the DG in terms
