This study focuses on hybridization hybridizationPV_CSP that exploit the low cost production from Photovoltaic (PV) and high dispatchability from concentrating solar power (CSP) plant coupled with a thermal energy storage (TES) system. This study presents a comparison between two dispatching strategies which are used to manage the energy produced in a hybrid PV_CSP plant to satisfy a 100MW baseload. The first dispatching strategy (DS1) prioritizes the operation of PV to satisfy the load while the CSP production is used to cover the missing load in daytime and evening, the second dispatching strategy (DS2) consists on operate PV in daytime and CSP in the evening. Results show the efficiency of DS1 compared to DS2 in term of annual energy, levelized cost of electricity (LCOE), number of hours satisfaction of load and energy dumped for an optimal value of storage size and solar multiple. The DS1 is the optimal choice to maximize annual energy and to minimize cost for hybrid PV_CSP plant in Ouarzazate for the case of study.
