Special Issue on Dispatchable RES and Flexibility in High RES Penetration Scenarios: Solutions for Further Deployment
Although the contribution of renewable energy sources (RES) in the electricity mix has significantly increased, the focus has been on intermittent RETs, whereas the required system flexibility is (mainly) provided by conventional power plants. In a decarbonised power system, this flexibility would have to be provided by RES-electricity (RES-e), increasing significantly the market value of dispatchable RES. Such currently available RETs include (among others) Concentrated Solar Power (CSP) with storage, hydropower, hybrid power systems and biomass. All these technologies can provide dispatchable power, as they have some kind of energy storage, e.g. dam, battery or thermal storage.
