Analysis of Solar and Wind-Based Hybrid Power Plant Using HOMER Software (Case Study: EMAS BAYU Hybrid Power Plant in Bondan, Cilacap)

Abstract

Solar energy is an energy source that is widely used because it is free energy, eco-friendly and very abundant, especially in tropical countries. However, the energy obtained from solar energy is inconsistent and is heavily influenced by environmental factors. Recently, many researchers have developed hybrid power plants which combine two or more different energy sources in the same system. In this research, we develop a hybrid power plant with an off-grid system (not connected to the national electricity company) that utilizes solar and wind energy. The hybrid power plant being developed is installed in Bondan hamlet, Kampung Laut District, Cilacap Regency. The installed power plant is determined for its performance by analyzing several parameters such as total energy production, net present cost (NPC) and cost of energy (COE). These parameters are analyzed using software which called hybrid optimization of multiple energy resources (HOMER). The simulation results show that the total energy generated from photovoltaics (PV) is 5.8 times higher than that of the wind turbine, with details being 10,480 kWh/year from PV and 1,805 kWh/year from the wind turbine. For the COE and NPC values are Rp. 14,266/kWh and Rp. 1,190,000,000, respectively.
