With the development of the modern electricity market

integrated energy buildings are also gradually participating in this market.A day-ahead bidding strategy is proposed for integrated energy building clusters

taking into account electric energy sharing via electric vehicles and incorporatingthe thermal storage characteristics of buildings.Firstly

the operation mechanism and framework of the day-ahead market for the integrated energy building group are proposed.Energy management within each building is coordinated by introducing agents as a third party

and a day-ahead bidding strategy for the building group is formulated.Secondly

a model of electric vehicle(EV)clusters is established by utilizing travel chains to cluster EVs belonging to the integrated energy building

taking into account the characteristics of mobile energy storage..Then

combining the analysis of building thermal storage characteristics and resource models

the agent considers the operational constraints of each building and the revenue from the energy market to establish a day-ahead market bidding model. Finally

by solving the model

we provide the operating plan for each building and the optimal day-ahead bidding strategy for the building cluster.

Additionally

we analyze the impact of electric vehicle(EV)energy sharing on day-ahead bidding.The results show that leveraging the mobile energy storage characteristics of EVs under power sharing can effectively reduce the number of power purchase bids in the building group during periods of high electricity prices.Furthermore

it can increase the number of electricity sales bids during these times

which can reduce the total operating cost of the agents of the integrated energy building group by 13.09%.
