Techno-Economic Analysis of Renewable Power System for a Remote Mosque in Libya

摘要

This paper presents a study of optimizing the design of electrical supply for providing the electrical loads in a remote mosque in Libya according to its energy requirements. Typical energy consumption daily profiles for the four seasons were designed based on a medium size mosque. HOMER software was used as the sizing and optimization tool to determine the optimum size and specifications of renewable system components, estimation of system cost and corresponding produced electrical energy. The results show that In the case when the renewable resources are at their minimum values and the fuel price is maximum, The most feasible system economically is PV/Gen/Battery with a minimum total net present cost (NPC) of 184094$ and minimum cost of energy (COE) of 0.478 $/kWh, and renewable fraction of 31%. For the case when the renewable resources and the fuel prices are at average values The optimal solution is PV/Gen/Battery with total net present cost (NPC) of 147485$ and cost of energy (COE) of 0.383 $/kWh, and renewable fraction of 33%. When the renewable resources are at maximum and the fuel price is minimum the most feasible economically system of this case is PV/Gen/Battery with total net present cost (NPC) of 119311$ and cost of energy (COE) of 0.310 $/kWh, and renewable fraction of 29%. Also it is found that providing electricity to the mosque using PV system is very beneficial and economical, especially considering the decreasing prices of PV systems and their increasing efficiencies and reliability and also the diffuclaties associated with transporting the fuel to the diesl generator and its maintenance. They have also the advantage of maintaining a clean environment.
