As the underlying terminal of multi-energy system

integrated community energy system(ICES)is featured with multi-energy complementary and integrated optimization operation. It is important to study its market operation mechanism for the development of integrated energy system and the consumption of renewable energy. Firstly

a model of ICES is established

including energy operator

user with distributed photovoltaic(PV)and electric vehicle(EV)charging agent. A trading mechanism in ICES is also proposed

in which the energy operator is the market leader. Secondly

a tripartite non-cooperative game is proposed

in which the three types of market entities rationally pursuit their own maximized interests. Finally

the proposed game model is solved in a typical winter scenario of the business ICES. Results demonstrate that the energy operator can get a certain profit by selling energy to the others. User with distributed PV participating in the market competition is able to increase the utilization of PV resource and reduce the cost of energy consumption by selling its remaining PV resource. By choosing the bids of other market entities and setting the best charging strategy

EV charging agent can not only reduce the cost of energy consumption

but also help users to consume the excessive PV power and reduce the peak load of distribution network in early peak hours.
