Techno-economic Assessement of Hybrid Energy System for a Stand-Alone Load in Morocco

The use of renewable energy is growing faster because it is green, it enables a long term energy supply, easily available and is therefore very advantageous in remote areas. However, the renewable energy sources are intermittent. This is why, a multi-source or hybrid energy system (HES), is actually widely used because it is usually more efficient than a single-source system in terms of cost, efficiency, reliability. But the hybrid energy system (HES) presents many technical challenges especially; the choice of the optimal sizing or the best combination of sources which is the most reliable, the most economical and the most sustainable. The purpose of this paper is to investigate the techno-economical feasibility of PV/WindTurbine/Battery hybrid system feeding a domestic house in seven geographical locations in Morocco. The HOMER software is used in order to compare the hybrid system cost, the cost of a PV/Battery system and the cost of a wind/battery system. The aim of this study is to assess different configurations of hybrid system in order to further promote renewable energy generation in Morocco by providing a road map for those who want to design and implement successfully renewable energy systems in different locations in Morocco. In fact, the other studies investigated the most economical hybrid system in only one location in Morocco. The simulation results from HOMER show that under different climatic conditions, the PV/Battery system is the most economically feasible configuration for powering a stand-alone domestic load in the seven selected geographical locations in Morocco. Also, a Pearson Correlation based on SPSS software was used in order to determine if there is a relationship between the cost of the PV/Battery system and the solar radiation in each city. The results show that the level and standard deviation of solar radiation impact the system cost..
