Research on calling sequence of peaking regulation means in power system with pumped hydro power (PHP) station

In this paper, the pumped storage power station and other conventional power sources will be considered to participate in the peaking regulation of power system, and the adjustment order to obey has been studied. Based on the key concepts including continuous ramping events and unit capacity adjustment cost, an comprehensive cost optimization model for the adjustment order of different peaking-regulation measures is proposed, in which the characteristics of the system load ramping, pumped storage power station characteristics, all kinds of peak adjustment means cost have been taken into consideration. The example has shown that the method can effectively realize the sorting of many kinds of peaking regulation measures in the power system. It also has shown that the calling order of the pumped storage power station not always takes the first place as the conventional consideration, which is necessary to combine with the specific conditions of the system.
