An economic dispatch strategy of micro grid based on sequential quadratic programming is introduced and formulated in the authors’ former paper in the context of mathematical model and formulations. In this paper, a small micro grid system in Yantai City, established by Shandong Electric Power Company, is used to investigate the performance of the proposed model in more detail. The results show that: in the independent micro grid operating mode, when the load is small, the operating costs of micro grid have a large difference before and after the control. In the grid-connected operation mode, the micro grid generates as recommended is more economical than full-power generation. Therefore, this paper can achieve the optimal output of each micro source and the economic operation with satisfying the load requirements.
