Day-ahead Energy Management of Energy HUB with Coupling of Heat and Electricity Considering Gas Distribution Coefficient

Realizing multi-energy optimization management is very important for the microgrids (MGs) with different forms of multi-energy. This paper proposes a community-level energy system (CES) which consists of community-level energy hub (CEH) and the users with electric and thermal demand. Firstly, the optimization model of users is designed, where the users can adjust the shiftable load and thermal demand spontaneously according to the internal electricity price and heat price. Secondly, the CEH achieves heat and electricity coupled energy management considering the gas distribution coefficient, and gets optimal strategies according to the best response of users. Then the Stackelberg game model is applied, where the CEH acts as the leader and the users act as the followers. Finally, the case study shows the effectiveness of the proposed model.
