【摘要】：为准确、快速地获取配电网故障恢复最优策略,提出基于节点状态优化的故障恢复混合整数线性规划方法。首先提出节点状态变量概念及其节点属性和电源属性,在此基础上建立节点状态变量-开关状态变量的线性函数关系,即开关状态线性模型;然后运用恒功率负荷线性化方法,建立基于基尔霍夫定律的电流及电压线性等式,等式中节点电压及支路电流等状态变量受节点状态变量及开关状态变量的约束;最后形成以切负荷及开关操作次数最少为目标的故障配电网最优潮流混合整数线性规划模型,即故障恢复模型。算例仿真验证了所提模型的合理性及有效性。
[Abstract]:In order to obtain the optimal strategy for fault recovery of distribution network accurately and quickly, a hybrid integer linear programming method for fault recovery based on node state optimization is proposed. Firstly, the concept of node state variable, its node attribute and power supply attribute are proposed, and then the linear function relationship between node state variable and switching state variable is established, which is called switching state linear model, and then the method of constant power load linearization is used. A linear equation of current and voltage based on Kirchhoff's law is established in which the state variables such as node voltage and branch current are constrained by node state variables and switching state variables. Finally, a hybrid integer linear programming model for optimal power flow in a fault distribution network, i.e., a fault recovery model, is developed, which aims at minimizing the load cutting and switching operation times. The simulation results show that the proposed model is reasonable and effective.
