Unit Commitment in Dual Generation Systems Using Grey Wolf Algorithm

This paper has developed a metaheuristic-based methodology to commit and allocate the load demand among the running dual heat and power sources. The proposed two-stage process using Grey Wolf Algorithm (GWA) engages suitable heat and power units and performs the combined dispatch. The method was tested and compared to demonstrate its effectiveness with the support of test systems containing 11, 22, 66 and 88 and a large system containing 110 units. The numerical results revealed that the proposed method can find a solution to the best fit in the Feasible Operating Region (FOR), and moreover, it is cost-effective with respect to other algorithm results.
