In the coming decades, proportion of wind–solar energy in power system significantly increases, resulting to uncertainties fluctuation abundant regions. The flexibility operation Pumped Storage Power Plants (PSPPs) has already been widely recognized regulate fluctuations; however, less is known about regulation reliability PSPP affected by them. It a challenge, since various exist during this p...

Energy storage is a key issue when integrating large amounts of intermittent and nondispatchable renewable energy sources into electric power systems. To be able to maintain the instantaneous power balance and to compensate for the influence of power fluctuations that might result from renewable sources, flexible capability for power control is needed. Therefore, sufficient energy storage with ...

Due to electricity market deregulation, the contribution of hydroelectric power plants to secondary control becomes of major interest regarding the electrical grid stability. Besides the grid stability improvements obtained with secondary control, the power utilities are more and more concerned by the influence of the constantly changing power set point on the lifetime of the power plant compon...
