PEMODELAN DAN OPTIMASI SISTEM HIBRIDA PLTS–PLTB–GRID BERDASARKAN POTENSI ENERGI LOKAL MENGGUNAKAN HOMER PRO DI DESA GILI GEDE INDAH

This study develops and optimizes a PV–wind–grid hybrid energy system based on local renewable energy potential in Gili Gede Indah Village, West Lombok, Indonesia, using HOMER Pro. The analysis considers solar and wind resources, electricity demand, and techno-economic parameters to identify an appropriate system configuration for the study area. The simulation results show that the selected configuration consists of a 1,200 kW PV system, five 10 kW wind turbines, a grid connection with a capacity of 999.99 kW, and an 800 kW converter. The system produces 2,053,522 kWh/year from PV and 50,333 kWh/year from wind, while the grid supplies 649,741 kWh/year. The modeled annual electricity demand is 1,149,524 kWh, with zero unmet electrical load. The resulting NPC and COE are IDR 5,501,519,000 and IDR 165.86/kWh, respectively, while the Renewable Fraction is 74.7%. The results indicate that the modeled PV–wind–grid configuration can meet the simulated electricity demand and provide the evaluated technical and economic performance under the assumptions applied in HOMER Pro.
