Abstract
Unit commitment is an important aspect of optimal operation of power system. In this paper, the wind power accommodation and flexible load response are proposed to evaluate unit commitment problems. Based on the evaluation functions, the optimization of unit commitment problems is translated into constraints multi-objective optimization problem. These objectives are modeled with a differential evolution algorithm with self-adaptive improved strategies method to evaluate their imprecise nature. The model and algorithms are applied to calculate a case of 10 units. It is shown that the system needs to have more spinning reserve and increase the peak regulation capacity of each time period. The results show that the proposed modeling method can provide a useful guidance for unit commitment problems
