Multi-energy micro grid can realize integrated energy system in distribution network/client, but the combination of power system and natural gas system will make the uncertainty in system scheduling become prominent. Therefore, based on the analysis of the physical characteristics of the power/natural gas system and the analysis of the key factors of user demand response resources, renewable energy unit output and load uncertainty, a day-ahead scheduling optimization model of multi-energy micro grid is established in this paper. Based on the Matlab environment, the simulation results show that the two-stage stochastic optimization model is effective. The simulation results show that the proposed optimization model can improve the reliability and economy of multi-energy micro-grid system, and has good practical application value.
