Manegement of pumped storage hydro plant coupled with wind farm

Abstract

Renewable energy sources, particularly wind turbine generators, are considered an important generation alternatives in electric power systems due to their lesser environmental impact. However, due to the variation of wind speed, wind energy is a fluctuated source and remains uncertain. It has an impact in grid stability. In this context, in order to improve the output characteristics of wind farms, several operators are going to develop new solutions. In this study, we propose a solution that allows limiting the wind power fluctuated and increasing wind energy penetration into power network. Then, we focus our attention on the cooperation between a wind farms and hydro-storage station with a given pumping capacity. In this paper, we propose method of management based on strategy that allows using the storage system in the best position.
