Decentralized wind-PV-diesel based hybrid power generation

This paper proposed a new wind-PV-diesel based hybrid power system to determine the economic viability of a stand-alone renewable energy system for remote area. The main target of the current analysis is to identify the optimum size of the hybrid system, that is able to meet all the energy demand of 51 MWh/day primary load with 4.3 MW peak load for the village with the lowest cost of energy (COE) and the operating cost. In this study we have considered the village Rawdat Ben Habbas in Saudi Arabia, currently the electricity is supplying to the village from a diesel power plant consisting of eight diesel generating units. The proposed hybrid model with 54% renewable energy integration has the ability to fulfill the energy requirements of the village under investigation with COE 0.176 $/KWh and the operating cost 1980,659 $/yr., that is economically cost effective rather than the diesel generator only system. The proposed hybrid system consists of three wind turbines each of 1650KW, PV panels of 500 KW, three diesel generating units of 1120 KW and one diesel generating units of 800 KW. According to the result, by using the proposed hybrid model with 54% renewable fraction, it is possible to reduce CO2 emissions about 41.44% as compared to the diesel generators only system. The well-known energy modeling software for renewable energy based hybrid power systems; HOMER is used to complete the present analysis.
