Demand Response Unit Commitment using Modified Hybrid Method in Power System

Abstract

Abstract: This paper presents a new modified hybrid method in predicting the optimal value of the demand response unit commitment optimization problem. Overloading the operation of generators during peak loads is cumbersome. Demand-side management is employed to smoothen the peak loads incorporated with unit commitment followed by dispatching of committed units for minimization of cost and emission. The modified hybrid method makes use of a modified non-dominant sorting genetic algorithm (MNSGA-II) and modified population variant differential evolution (MPVDE) techniques. In price-based demand response, customers are awarded incentives based on their contribution to the demand response program. The proposed modified hybrid method is effectively applied to two test systems.
