Exploring backup requirements to complement wind, solar and hydro generation in a highly renewable Spanish power system

A weather-driven model is used to investigate the requirements for the backup generation (annual energy, power capacity and flexibility) in a power system with different penetrations of wind, solar photovoltaics, and hydroelectricity. The impact of interannual variability is assessed by using 26 yea...
