Design and Management of Renewable Energy Systems for Isolated Communities with No Grid Connection

The growing demand for energy and the need to reduce dependence on non-renewable sources have driven the research and application of sustainable technologies. In this context, an integrated solution that combines distributed energy generation from renewable sources, such as wind and hydro, with efficient management of household energy consumption is proposed. This study focuses on the hybrid renewable energy system simulation analysis designed to meet the demand of an off-grid household in a self-consumption mode. This combination of technologies allows adaptation to geographical location, resource availability, and consumer-specific needs, where only renewable resources are available to power non-grid-connected local communities in less developed areas. Given that wind and hydroelectric energy are variable resources over time, either seasonally or hourly, the aim is to find an optimal balance that maximizes electricity demand coverage for the longest possible time. A system is designed to integrate both energy sources, with one acting as a backup source, if necessary, thus ensuring a constant supply of electricity without oversizing the systems. This approach aims to maximize energy efficiency and contributes to closing the electricity access gap in communities not connected to the conventional electricity grid. The detailed analysis of this hybrid system provides valuable information for designing and implementing decentralized energy solutions in isolated communities. The paper represents a unique contribution to the state of the art in wind energy and hydropower hybrid renewable energy systems for isolated communities. It represents an advanced study on managing this type of installation by applying energy efficiency protocols and methods to optimize the system’s performance.
