Flexibility for Power Systems
Flexibility is the ability of a power system to manage variability of demand and generation. Flexibility includes power regulation and operational reserves, which have historically depended on thermal power plants. On top of dispatchable power generators, there are new sources of flexibility increasingly used, like energy storage, interconnectors and demand side management. The optimal combination of flexibility is a key issue for grid operation under large amounts of wind and solar.
