Optimal Design of a Pumped-Hydro Energy Storage System
Abstract
En este proyecto se analiza la manera correcta de optimizar la generación y consumo de energía eléctrica así como el diseño de una central de bombeo atendiendo a la energía eléctrica demandada a cada momento, potencia instalada y capacidad de embalses. Energy storage systems are a step forward for renewable energy generation. These systems cover energy shortages at peak demand by storing energy generated at times of low demand. Reversible pumping systems are the perfect solution for energy generation regulation with respect to demand. This article discusses the optimal design of a reversible pumping station in terms of power input/output and mass of water capacity, as well as its way of generating/consuming electricity from the grid with a Model Predictive Control. In this design two cases are analyzed; an ideal case where there are no losses in the plant other than the performance of the equipment, and another case where friction losses exist depending on the design of the pipes.
