As a means to increase the consumption rate of clean energy, the park-level multi-energy system (MES) is being paid more and more attention by scholars. This paper proposes a day-ahead economic dispatch of park-level multi-energy system with gas-heat energy storages and high penetration of renewable generation. In this paper, the objective function of the MES is established, and the related constraints are described. The operation of the MES when there are gas storage equipment and heat storage equipment, as well as power-to-gas equipment is also discussed. The proposed mathematical model is established using MATLAB and solved by Gurobi. We also observe the operation mode and the cost of the MES under different renewable energy penetration rates. It is concluded that the presence of energy storage and energy storage capacity help to increase the consumption ratio of wind and solar energy.
