Stand-alone hybrid renewable energy system — An alternative to increased energy demand

This paper presents the feasibility and technical insights of hybrid renewable energy system as an alternative energy to the existing conventional energy for the isolated load demand. The system is initially modeled with solar PV, battery and diesel generator and then optimized for a certain local load demand with HOMER simulation tool. Cycle charging dispatch strategy is adopted for the simulation and the feasibility analysis is also carried out with respect to its net present cost and levelized cost of energy. The cost of energy is comparable with the existing cost of energy and it is feasible to use the hybrid system keeping in mind the fact of detrimental effect of coal based energy to the environment and cost of electrification through the extension of existing grid.
