The growth of these systems is essential for improving the integration of renewables and avoiding dependence on fossil fuel sources, such as gas or oil. This paper presents the modeling and application of an optimal hourly management model of grid-connected photovoltaic and wind power plants integrated with reversible pump-turbine units to maximize the monthly operating profits of the energy system and meet electricity demand. The techno-economic dispatch model is formulated as a mixed-integer optimization problem. To assess the proposed model, it is applied to a Spanish case study system, and the results are obtained for an entire year. The combination of renewable energy and pumped hydro energy storage reduces energy dependence by decreasing energy costs by 27 % compared with a system without storage to satisfy the required electricity demand. The findings confirm that storage plays a key role in energy transition to ensure the security and stability of power systems with a higher share of renewable generation. info:eu-repo/semantics/openAccess by-nc-nd http://creativecommons.org/licenses/by-nc-nd/3.0/es/ 8.9 2023 ENERGY & FUELS 29 / 171 = 0.17 2023 Q1 T1 1.595 2023 Electrical and Electronic Engineering 2023 Q1 Renewable Energy, Sustainability and the Environment 2023 Q1 Energy Engineering and Power Technology 2023 Q1 11.8 2023 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Yusta, Jose M.
