Energetic Complementarity with Hydropower and the Possibility of Storage in Batteries and Water Reservoirs

The complementarity of energy resources used in hybrid systems can open new perspectives for the design of energy systems. Complementarity may be important as a tool for decision makers can sort projects and may be important for an energy system can overcome periods of energy scarcity. This chapter proposes a way to assess the complementarity of energy resources with a dimensionless index and study the effect of different degrees of complementarity on the performance of PV hydro hybrid systems. This chapter also presents some case studies, discussing consequences of complementarity in real systems.
