A Study on the Optimal Plant Mix of Pump Storage in the Competitive Power Markets

경쟁시장에서의 양수발전 적정 규모 산정에 관한 연구

In the past, pumping-storage generator pumped the water from the lower part storage to the upper part storage during the base load periods. And, it generated during the peak load or when other generator was outage. However, pumping-storage generator will operate different ways in the competitive power markets. It will pump during lower price periods and generate at higher price periods. This paper presents economic analysis of pumping-storage generator using price (or SMP) duration curve.
