A methodological approach for assessing flexibility and capacity value in renewable-dominated power systems: A Spanish case study in 2030

Maintaining the security of supply is one of the challenges that system operators face. Variability and uncertainty increase due to the penetration of variable renewable energy sources such as solar and wind, while flexible technologies such as traditional thermal units are phased out to reduce emis...
