| 摘要: |
| 动态网络重构能有效降低配电网的网络损耗以及分布式电源的弃风弃光量，为此提出了基于双层动态时段划分的配电网重构方法。上层优化中以网损成本与弃风弃光惩罚费用之和最小为优化目标，决策变量为主动管理元素的出力；下层优化中则以网损最小为目标函数来确定各时段开关状态量。为了减小模型的规模与复杂度，提出了将割集法作为辐射状约束的表示方法。同时，将该模型转化为混合整数二阶锥规划模型，并结合和声搜索算法对其进行求解。通过改进IEEE 33节点系统进行仿真，验证了所提方法的实用性和有效性。 |

| Abstract: |
| Dynamic network reconfiguration can effectively reduce the network loss of distribution network and the abandoned wind power and photovoltaic output of distributed generation. Therefore, a distribution network reconfiguration method based on bi-level dynamic time division is proposed. In the upper-level optimization, taking the minimum sum of network loss cost and penalty cost of the abandoned wind power and photovoltaic as the optimization objective, and the output of active management element as the decision varia-ble. In the lower-level optimization, taking the minimum network loss as the objective function to determine the switching state of each time period. In order to reduce the scale and complexity of the model, the cut set method is proposed to represent the radial constraints. At the same time, the above model is transformed into a mixed integer second-order cone programming model and it is solved combined with harmony search algorithm. The simulation of the improved IEEE 33-bus system is carried out to verify the practicability and effectiveness of the proposed method. |
