This paper presents a novel real multi-objective approach for thermal unit commitment (UC) problem solution in Niamey (Niger). The proposed methodology consists of four conventional thermal generating units and imported power from a neighboring country in addition to future inclusion of Photovoltaic (PV) power, Wind Turbine Generators (WTGs), and Pumped Hydro Energy Storage (PHES). Minimization of total daily operating cost and decreasing the maximum daily mismatch between load demand and generation are considered as two objective functions in two cases. In the first case, UC with thermal units considering the imported power (IMP), PV and PHES is determined. In the second case, WTGs are introduced and the IMP is removed in order to get rid of its economical and political problems. ε-MOGA (epsilon Multi-Objective Genetic Algorithm) is used to obtain an optimal unit commitment problem solution with consideration of PV, WTGs and PHES. The effectiveness and robustness of the proposed scheme is verified by numerical simulations using MATLAB environment.
