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.
