To address this issue, this study explores the synergistic optimization of wind and solar photovoltaic resources to mitigate power output variability, reducing the strain on local grids and lessening the reliance on balancing power in high-penetration renewable energy systems. This critical role of providing stability can be effectively fulfilled by run-of-river hydropower plants, which can complement fluctuations without compromising their standard operational capabilities. In this research, we employ a straightforward energy balance model to analyze the feasibility of a 100 MW virtual hybrid power plant, focusing on the northern region of Portugal as a case study. Leveraging actual consumption and conceptual production data, our investigation identifies a specific run-of-river plant that aligns with the proposed strategy, demonstrating the practical applicability of this approach.<\/jats:p>","DOI":"10.3390\/en18030585","type":"journal-article","created":{"date-parts":[[2025,1,27]],"date-time":"2025-01-27T11:38:49Z","timestamp":1737977929000},"page":"585","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Hybrid Variable Renewable Power Plants: A Case Study of ROR Hydro Arbitrage"],"prefix":"10.3390","volume":"18","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-1562-7821","authenticated-orcid":false,"given":"Isabel","family":"Catarino","sequence":"first","affiliation":[{"name":"LIBPhys-UNL, Department of Physics, NOVA School of Science and Technology, NOVA University Lisbon, 2829-516 Caparica, Portugal"}]},{"given":"In\u00eas","family":"Rom\u00e3o","sequence":"additional","affiliation":[{"name":"LIBPhys-UNL, Department of Physics, NOVA School of Science and Technology, NOVA University Lisbon, 2829-516 Caparica, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0476-2526","authenticated-orcid":false,"given":"Ana","family":"Estanqueiro","sequence":"additional","affiliation":[{"name":"LNEG\u2014Laborat\u00f3rio Nacional de Energia e Geologia, 1649-038 Lisboa, Portugal"}]}],"member":"1968","published-online":{"date-parts":[[2025,1,26]]},"reference":[{"key":"ref_1","unstructured":"European Union (2022, December 20).
