摘　　要：针对含可再生能源的配电网动态重构,提出一种基于期望值模型的启发式配电网动态重构方法。构造了可再生能源出力的混合高斯分布模型,基于七步概率近似方法提取典型场景,对场景建立配电网动态重构的期望值模型。在基于场景采用最优流模式算法求解各时段静态重构方案的基础上,提出网损增量与开关动作次数变化量比值启发式规则,减少开关动作次数,获得最优或近似最优的动态重构方案。最后,以含有可再生能源系统的IEEE-33节点系统为例验证了所提方法的有效性。Aiming at the dynamic reconfiguration of the distribution network with renewable energy,a heuristic method for the dynamic reconfiguration of the distribution network based on the expected value model is proposed.A mixed Gaussian distribution model of renewable energy output is constructed,typical scenes are extracted based on the seven-step probability approximation method,and the expected value model of the dynamic reconstruction of the distribution network is established for the scenes.Based on the static reconfiguration of the optimal flow method at each time period based on the scene,a heuristic rule of the ratio of the network loss increment to the number of switching actions is proposed to reduce the number of switching actions and obtain the optimal or nearly optimal dynamic reconfiguration scheme.The IEEE-33 bus system with renewable energy system verifies the effectiveness of the method proposed in this paper.
