With the high development of energysystem interconnection and energy transaction marketization

the regional interconnection of Multi-Integrated Energy System（MIES）makes the energy utilization efficiency of Integrated Energy System （IES）more efficient and the economic benefits more considerable.Firstly

this paper constructs the energy sharing architecture of MIES cooperation alliance under the background of multi-energy market

and establishes the power and backup point to point （P2P）transaction model between MIES.Secondly

the uncertainty of new energy output

the risk of electricity price and reserve price fluctuation are analyzed.In this paper

the conditional value-at-risk （CVaR）theory is used to construct the risk cost function and incorporate it into the comprehensive operation cost model.Finally

the Alternating Direction Method of Multipliers （ADMM）is selected for distributed solution

and the correctness and rationality of the model are verified by an example analysis.The minimization of MIES operating cost and the maximization of payment income are realized

which reflects the influence of different conditional risk aversion coefficients on MIES.
