电力系统应急服务多点最优选址规划

合理规划电力系统应急服务点对于保证应急资源及时运送,进而降低停电损失具有重要意义。现有电力系统应急方面的研究多侧重于应急平台建设和相关指标体系构建,而对应急服务点选址优化问题则研究较少。在此背景下,通过综合考虑用户停电损失、停电时限约束及应急服务点的服务成本,建立了以电力应急总成本最小为优化目标的应急服务多点选址的优化模型,并采用Floyd算法求解该优化模型。最后,用算例说明了所构建模型的正确性与所采用算法的有效性。

Optimal Siting of Power Emergency Multi-point Service Provisions

Reasonable siting of power emergency multi-point service provisions is very demanding for ensuring timely delivery of power emergency service resources, and hence reduces the outage costs of power supply. The existing research work on power emergency service provisions is mainly focused on the establishment of a power emergency service platform and the associate evaluation system. Up to now, the optimal siting of power emergency service provisions has not yet been systematically addressed. Given this background, with the minimization of the overall cost of power emergency service provisions as the objective and the permitted outage durations of all loads as constraints, an optimization model is presented for the optimal multi-point siting problem of power emergency service provisions. The overall cost is composed of the annual construction and service cost of each service point, as well as power supply interruption costs of all important loads. Then, the well-established Floyd algorithm is employed to solve the developed optimization model. Finally, a sample system is served for demonstrating the developed optimization model and solving algorithm.
