Variable speed pumped storage hydropower for integration of wind energy in isolated grids : case description and control strategies
This paper presents the use of variable speed pumped storage hydropower plants for balancing power fluctuations from wind power in an isolated grid. A topology based on a synchronous machine and a full scale back-to-back voltage source converter is suggested for obtaining variable speed operation of...
