ABSTRACT
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.
