INTRODUCTION.
This is because in the proposed hybridization, the ESS provides highly fluctuating power most of the time, and this operation is not energy-intensive (large spikes of power). However, to avoid the shutdown of the hydro generator and for the prevention of operation in the low part load region, energy requirements become much higher.
