This paper presents a formulation and simulation of unit commitment for thermal units integrated with wind energy systems by emphasizing on demand response management in smart grids. The renewable energy resources are included in this model due to their low electricity cost and positive effect on environment. The proposed method is solved using MGWO algorithm in MATLAB software. The problem is finding a solution which satisfies the constraints and minimizes the objective cost function. As a case study, results on IEEE ten-unit system are presented in this paper. The demand elasticity pertaining matrix to electricity price is defined in different conditions and applied to cost-function to investigate their effectiveness. The numerical tests and results show that their inclusion with the conventional power generating sources reduces the operational cost
