Energy Storage
Explain what is meant by intermittent power generation.
Generation in which the real power output is a function of some uncontrollable variable. For example, wind generation being dictated by wind speed and availability. PV, tidal are also included. Unplanned maintenance of fossil-fuelled systems are not part of intermittent generation.
Explain why intermittent power generation imposes additional complexities on the electricity system.
Adding to cost because of:
Additional balancing: short term variations in power generation add to supply-demand imbalance. Requires additional responsive plants to be contracted for part-load duty.
System security: plants retained to meet peak demand/ difficulty in quantifying.
