摘要：
The integrated energy system and energy hub ( EH) can not only implement energy complementary coordination, but also improve power quality. In this paper, an integrated energy system considering power to gas (PtG) is composed of electric power distribution system, district heating system, natural gas distribution system and energy hub. In order to realize the optimal allocation of resources, we have constructed an optimization model oftwo layers. By constructing a Lagrange function, the model is transformed into a mixed integer linear program (MILP) combined with Karush-Kuhn-Tucker (KKT) optimality conditions, and then common commercial software CPLEX is used to solve this model. Finally, a case study is used to prove the effectiveness ofthe proposed model and method. The performances of PtG promoting the overall economic benefits and enhancingthe reliability level of electrical loads are also analyzed.
