Abstract

In this paper, an energy dispatching model for hierarchical management of multi-microgrid architecture with electricity-to-gas in low-carbon background is established under the condition of considering the uncertainty of wind and solar. In the upper layer, a hybrid energy operator model is constructed, and the improved snake algorithm is used to seek the optimal internal electricity price between the operator and the microgrid group, and the power and hydrogen transfer is realized under the condition of power exchange and time-of-use electricity price applied to the main network, and the dispatch of the main network and the microgrid group is coordinated respectively. The lower layer uses the solver to construct a mutual cooperative scheduling model between microgrid groups, and introduces the gradient carbon trading mechanism into the dispatching stage of each microgrid. Through simulation verification, the model finally realizes the role of peak shaving and valley filling of the main grid through time-of-use electricity price and energy storage and hydrogen storage by operators, and at the same time, reduces carbon emissions in the stepped carbon trading mode, considers the environmental cost, and realizes the cooperation alliance between the microgrid group and the cooperative operator.
