Desain Sistem On-Grid Energi Terbarukan Skala Rumah Tangga Menggunakan Perangkat Lunak HOMER

Abstract

Electricity demand increases along with an increasing population. Renewable energy power plants are experiencing an increase in their use. This increase occurred because the world's electricity needs are rising every year, so the development of renewable energy power plants continues. Indonesia's state-owned power plants supply electricity more from non-renewable energy sources than renewable energy sources. Therefore, there is a need for renewable energy sources that can supply electricity in Indonesia. This research discusses an efficient renewable energy system for residential and the total installation costs for on-grid systems in Bandung, Indonesia. The research method used is collecting solar radiation data, equipment specifications and other data needed and then optimized. The simulation model uses HOMER software. HOMER is used to determine the best technically estimated cost, payback period, and NPC. Based on the optimization results, the system configuration can supply the electricity load 45.5% of daily load consumption with a total NPC cost is 75,300,000 million with a payback period of 7 years. In addition, the on-grid system produces 1400 kg of carbon dioxide (CO2) emissions per year from diesel generators, lower than the CO2 emissions from systems that only comprise diesel generators reaching 114 tons per year.
