Abstract: [Introduction] The monitoring system and control strategy of micro-grid has been considered as one of the difficulties to be solved in the micro-grid design process. [Method] Based on project exssperience, the design method of the micro-gird monitoring system and its control strategy were described in the paper. And then, the functional framework, the network structure and the control strategies of monitoring system in the micro-grid were proposed, at the same time, the paper gave the concrete process of PCC switching strategy. [Result] Finally, a project example was given in the paper,the network structure and the control strategies of the example were proposed. [Conclusion] The example shows the effectiveness of the program,it has guiding significance for practical project.
