Design and Sizing of Energy Storage for Grid Connected PV Power Plants

By their nature PV power generation can be considered static. This means they do not have inertia as rotating machines do, and thus, they cannot handle transient load demands that go over their instantaneous maximum power point. In addition, when compared to traditional generators their power ramp rate is much steeper, being able to reach values of 90% per minute and higher. Both characteristics have an impact on power system operation,...
