Chemical reaction optimization applied in economic dispatch problems

This paper proposes an effective algorithm called chemical reaction optimization (CRO) in the field of power system to solve economic load dispatch (ELD) problems involving different equality and inequality constraints. Complex constraints like prohibited operating zone and ramp rate limit are also considered. System transmission loss has also been considered in the test system. Chemical Reaction Optimization (CRO) imitates the interaction of molecules in a chemical reaction to reach from a higher energy unstable state to a low energy stable state. Simulation results reveal that the proposed approach does better than modern existing optimization techniques in terms quality of solution obtained and computational efficiency. Results also establish the robustness of the proposed methodology to solve ELD problems.
