Abstract

Pumped storage hydroelectricity is the most natural and almost the only bulk energy storage technology available today. Due to the variability of energy demand, and recently also of the supply side of the energy market, there is a need to compensate these differences. In market reality this is usually done on the so-called balancing market where energy prices are significantly higher than on the power exchange market. In this paper we introduce a mathematical model for simulating the operation of photovoltaic-powered pumped storage hydroelectricity along with an optimization model and a procedure for operation on the balancing market. A simulation was performed based on data covering the year 2015 with an hourly time step. The results from the proposed approach were juxtaposed with an optimal solution generated from the optimization model.
