Economic Analysis of On-Grid Photovoltaic-Generator Hybrid Energy Systems for Rural Electrification in Indonesia

Abstract

The increasing demand for electrical energy is causing conventional energy supplies to become insufficient, leading to power outages especially in remote areas. Additionally, the reliance on fossil fuels for energy contributes to global warming. There is a pressing need for additional renewable energy sources to meet these energy needs. Hybrid Energy Systems (HES), which combine two or more energy sources, offer a promising solution. This study aims to analyze a PV-generator hybrid system connected to the grid in several cities in East Nusa Tenggara. The hybrid system configurations are modeled using the Hybrid Optimization Model for Electric Renewable (HOMER) software. Simulation results indicate that the performance varies across cities due to environmental parameters. Among the cities studied, Alor demonstrated the highest efficiency and best energy production according to economic analysis and energy output data.
