摘要

This paper presents a real approach for thermal unit commitment(UC)problem solution in Niamey(Niger).The proposed methodology consists of four conventional thermal generating units and imported power(IMP)from a neighboring country as the existing grid in addition to the inclusion of Photovoltaic(PV)power,Wind Turbine Generators(WTGs),and Battery Energy Storage System(BESS).Minimization of the total daily operating cost is considered as the objective function in two cases.In the first case,UC with thermal units considering the IMP,PV and BESS is described.In the second case,WTGs are introduced beside high penetration of PV and BESS and the IMP is removed in order to get rid of its economical and mostly political problems.MILP(Mixed-Integer Linear Programming)is used here as the optimization technique to obtain an optimal unit commitment problem solution with consideration of PV,WTGs and BESS.The effectiveness and robustness of the proposed scheme is verified by numerical simulations using MATLAB environment.
