Abstract
Hybrid renewable energy systems (HRES) have emerged as an alternative to single-source systems. With the advantage of combining different energy profiles and exploiting the complementarity of sources, HRES have demonstrated to be a good option for increasing the adoption of renewable energy (RE) technologies, ensuring a stable energy supply, and making the system more cost-effective by sharing operations and maintenance activities, electrical infrastructure, and space leasing. Efficiently designing HRES is essential to ensure stable energy production while maintaining cost-effectiveness. When designing an HRES, the goal is to identify the optimal combination of RE sources and determine their respective sizes and types of equipment. Furthermore, the design process must consider the availability of the system and the operational plan with the most effective maintenance strategies for each unique combination of energy sources. This study aims to analyse the cost competitiveness of an HRES, assessing the economic feasibility of: new HRES or transitioning existing installations into HRES with the addition of new RE sources (e.g. complement an existent wind farm with photovoltaic panels). A cost model is integrated into the optimization approach to estimate lifelong farm costs and maximize an economic indicator. The farm's availability is modelled using a Markov chain. In addition, this study seeks to identify cost-saving opportunities by integrating different energy sources.
