This paper aims to extend knowledge about the performance of Economic load dispatch (ELD) considering renewable energy resources do with wind generation. The main objective of the ELD problems is to determine the optimal combination of power outputs of all generating units to meet the required demand at minimum cost while satisfying the constraint including the load demand balance. A General Algebraic Modeling System (GAMS) is used to minimize the objective function, while satisfying system operating constraints. General Algebraic Modeling System (GAMS) software has been utilized to solve the problem of non-smooth load dispatch by the scheduling of the active power of generators to check the capability of GAMS for non-smooth function and start-up cost based on Unit commitment (UC). The developed algorithm is tested on the IEEE-24 bus reliability test system considering variability in renewable energy sources and load demand. The results demonstrate the feasibility and effectiveness of the developed programming to minimize the total generation cost including the load demand balance.
