Optimization analysis for pumped energy storage systems in small isolated power systems

Andreas Poullikkas


In this work, a technical and economic analysis concerning the integration of pumped energy storage plants in small island power systems and in particular in the Cyprus power system is carried out. For the simulation of the current and future Cyprus generation system, the WASP IV software package is employed, which is a specialized simulation software used widely for the selection of the optimum expansion planning of the generation system. The electricity unit cost of the generation system for various investigated scenarios is then calculated. The simulation results indicate that under certain parameters the use of pumped energy storage systems can be beneficial for the large scale integration of renewable energy sources.
