Aiming at the economic optimal scheduling problem of microgrid,a multiobjective optimal scheduling strategy of microgrid based on improved ant colony optimization is proposed.Combined with the power generation characteristics of each power generation unit in the microgrid,a multiobjective optimal scheduling model of the microgrid is constructed to improve the shortcomings of the ant colony optimization,and the proposed optimization strategy is verified by Matlab.The results show that the optimization performance and convergence performance of the improved ant colony optimization are significantly better than those of the ant colony optimization,and the number of optimization iterations is reduced by 87%.The improved ant colony optimization can significantly reduce the total operating cost of the microgrid,and the output of each micro power supply is also in line with its working characteristics.This strategy has certain reference value and guiding role for the actual optimal dispatching of microgrid.
