Abstract: In order to ensure economic and reliable operation of micro power grid, reduce the pollution to the environment, an optimal dispatching model for microgrid is proposed, which considered the operating cost and environmental pollution of microgrid, through the adaptive weighting method weights for different fitness function are distributed, the multi-objective problem is changed to single objective problem. The improved gull algorithm is used to find the optimal configuration scheme. Gulls experiment results show that the improved algorithm has better ability for global optimization, the solving precision and convergence speed compared with the standard algorithm. The micro grid economic operation has certain advantages in solving the problem, and reducing the micro grid operation cost and the environmental pollution, improving the reliability of the micro grid operation.
