配网三相负荷不平衡自动调度方法

Automatic Scheduling Method of Three-Phase Load Imbalance in Distribution Network

受用户用电不确定性的影响,配电网三相负荷不平衡现象严重,为此,本文提出了一种考虑无功损耗和电压稳定的自动调度方法。该方法构建了无功损耗最小化和电压稳定裕度最大化的多目标调度模型,利用粒子群算法求解模型,避免陷入局部最优,以实现三相负荷不平衡的调度。实验结果表明,该方法具有较强的稳定性和较高的效率,可有效实现配网三相负荷不平衡的自动调度。

Due to the uncertainty of user electricity consumption,the phenomenon of three-phase load imbalance in the distribution network is severe.Therefore,this paper proposes an automatic scheduling method that considers reactive power loss and voltage stability.This method constructs a multi-objective scheduling model that minimizes reactive power loss and maximizes voltage stability margin.The model is solved using particle swarm optimization algorithm to avoid falling into local optima and achieve scheduling of three-phase load imbalance.The experimental results show that this method has strong stability and high efficiency,and can effectively achieve automatic scheduling of three-phase load imbalance in the distribution network.
