| Abstract: | In order to improve weak local search and low convergence speed of differential evolution algorithm, this paper proposes the method with great global search and high convergence speed for the economic optimization of micro grid, a method which combines different variation characteristics with annealing strategy. In the paper, it also establishes the model of environmental-protective and economic optimization of micro grid based on costs of fuel, oper- ation and maintenance, pollutant emission, and constraints on pollutant gas or greenhouse gas emission. The example proves that the model with great convergence and high calculation speed is feasible in economic optimization of mi- cro grid and improvement of DE algorithm. |
