2 2 1 1 improved. By analyzing micro-grid operating costs in the electricity market environment, the mathematical model of microgrid energy management, taking consideration of economic interests in contract periods, get established, where random variables get introduced. According to the concept of the confidence interval, the optimal model based on confidence interval gets proposed and the dealing methods of different random variables are illustrated. After that, the optimization ideas of changeable confidence interval get proposed. Finally, the effectiveness of the optimization method is confirmed by simulation example which proves that the method is able to solve the problem of microgrid energy management under power market environment.
