    Abstract

    Hybrid power plants based on diesel generator and renewable energy sources, like photovoltaic and wind energy, are an effective option to solve the power supply problem for remote and isolated areas far from the grids. Homer, a micropower optimization modelling software is used to analyze data for both wind speed and solar radiation in Sebesi Island. The software optimize the system configuration of the hybrid system by calculating energy balance on an hourly basis for each of the yearly 8760 hours, simulating system configurations at once and rank them according to its net present cost [1]. in this paper, configuration design optimization of the hybrid system is analyzed to fulfill the electricity demand in Sebesi Island taken into account the issue of CO2 emission reduction due to utilizaton of fossil fuel during diesel generator operation. Optimization is done with three conditions, a first condition with 2 diesel generating unit 40 kW and 50 kW each, secong condition a hybrid system with 25% maximum renewable fraction and a third condition a hybrid system with more than 25% minimum renewable fraction. The result obtained for the PV-wind-diesel hybrid are with 30% renewable fraction : 25% reduced CO2 emissions or 48 tons/year or 25% from the first condition with 2 diesel generating unit, and the cost of eletricity is the highest at $ 0.786/kWh, the net present cost of $ 1,503.710, the initial capital cost of $ 738.010 and excess power reaching 85.212 kWh or 31.4%. Keywords : Simulation, Hybrid Power Plant, Renewable fraction, Cost of Electricity, CO2 emission.
