Optimal Pumped Storage Operation with Interconnected Power Systems

This paper deals with the problem of obtaining the optimal scheduling of a pumped storage hydroelectric plant in combination with, several interconnected power systems. A special case of interest is the scheduling of pumped storage when the plant is jointly owned by several electric utilities. A mnathematical model is developed in order to determine the power flows between the different power systems and the pumped storage plant as well as the water flows inside the plant.
