    摘要:

    全能型供电所的科学选址,对于提升抢修效率,减少用户损失具有重要意义。为体现失负荷等级对供电所选址的影响,在分析全能型供电所业务特性的基础上,比较考虑失负荷等级2种情况下对应的抢修距离与成本的变化,建立供电所应急抢修多目标模型。采用 Pareto支配的多目标粒子群算法进行模型求解,利用拥挤距离排序以更新非劣解集,并确定最终优化方案。最后,通过算例得出计及失负荷等级情况下加权距离与综合成本均优于未考虑负荷等级情况。仿真结果显示,该文构建的应急抢修多目标选址模型和提出的求解方法对全能型供电所抢修策略具有一定的指导意义。

    Abstract:

    The scientific location of the VPSS is of great significance to improve the efficiency of emergency repair and reduce the loss of users. To reflect the impact of the load-loss level on the selected location of the power supply, this paper analyzes the service characteristics of the VPSS and compares whether the corresponding repair distance and cost change when the two conditions of the load-loss level are considered to establish the power substation emergency repair multi-objective model. After that, the pareto-dominated multi-objective particle swarm optimization algorithm is adopted to solve the model and the crowd distance sorting is utilized to update the non-inferior solution set and determine the final optimization scheme. Finally, the calculation example shows that the weighted distance and the comprehensive cost are better than the case of not considering the load level when the load level is taken into account. The results show that the multi-objective site selection model for emergency repairs constructed and the proposed solution method have certain guiding significance for the emergency repair strategies of the VPSS.
