In this paper, the main objective is the simulation of the electric supply for homes in remote areas located in Morocco (Oujda and Ouarzazate), Spain (Granada), and Algeria (Bechar). This simulation study is divided into two ideas, the first one is to optimize the hybrid system under a varied number of houses and the second part is to fix it in chosen values. This work relied on the particle swarm optimization (PSO) method to optimize and analyze the proposed stand-alone photovoltaic/wind/diesel/battery hybrid system. MATLAB software is used to run the simulations and to carry out the optimal solutions of the optimized system using a developed PSO algorithm. The PSO approach contains five principal operator axes, which are problem definition, PSO initial parameters, initialization, PSO main loop, and then run of the algorithm. Optimizing the system component sizes and reaching the minimum cost of energy (COE) were the function objectives of this optimization study. Moreover, calculation of the hydrogen production from the generated energy by PV and wind systems is performed. [ABSTRACT FROM AUTHOR]

This work is focused on the energy recovery potential of olive-oil industry wastes in the region of Tizi Ouzou (north of Algeria). A theoretical modelling and simulation study of a small-scale CHP plant fuelled with olive pomace and olive tree pruning is carried out. The power plant proposed is composed of a downdraft gasifier, an externally fired gas turbine reaching an optimum electric power of 75.8 and 170.22 kW of thermal power. The electric efficiency achieved is 18.56% and the CHP efficiency is 60.26% for olive tree pruning gasification. The simulation results showed a satisfactory syngas lower calorific value (4.12–4.39 MJ/kg) and a gasification efficiency of 78.3–79.8%. The economic analysis of the plant shows a feasible payback period between 5 and 6 years with an interesting Profitability Index and Internal Rate of Return above 20% for both biomasses considered. Finally, the electrical energy generated with the plant proposed can cover the annual consumption of more than 46,000 inhabitants in Tizi Ouzou province. [ABSTRACT FROM AUTHOR]
