Microgrids have emerged as a key interface for tying the power generated by localized generators based on renewable energy sources to the power grid. The conventional power grids are now obsolete since it is difficult to secure and operate numerous linked independent generators. However, given that they depend on unplanned environmental factors, these systems have an unstable generation. . The study explores heuristic, mathematical, and hybrid methods for microgrid sizing and optimization-based energy management approaches, addressing the need for detailed energy planning and seamless integration between these stages. Key findings emphasize the importance of optimal sizing to. .

From sustainability to economics, microgrids offer benefits for many businesses. A microgrid is a small electricity grid where electricity is produced, distributed and consumed. Microgrids can be independent from the main grid or connected to it.
Solar energy, while underexplored in Costa Rica compared to hydro and geothermal, has gained attention in recent literature. Smith and Paladino (2021) argue that solar photovoltaic (PV) systems offer a decentralized solution to complement hydro-heavy grids, reducing vulnerability to seasonal fluctuations.
While hydroelectric power dominates the energy mix at approximately 80% of electricity production, solar energy, though currently a smaller contributor, holds significant potential to diversify and stabilize the grid. This paper investigates Costa Rica's renewable energy journey, emphasizing solar power's evolving role.
