Research On Distributed Optimal Scheduling Of Smart Building Clusters Under Transactive Energy Mechanism

In recent years,the contradiction between energy demand and environment becomes increasingly prominent.All countries in the world begin to carry out energy transformation and solve the energy crisis and environmental problems by developing distributed energy.With the grid connection of a large number of distributed energy and the in-depth reform of power market,a variety of new stakeholders have been derived,among them,smart buildings actively managing their production,consumption and storage of energy,will play an increasingly important role in the future power system because they can participate in the market operation independently.Therefore,how to optimize the resource allocation of smart buildings,optimize the scheduling of smart building clusters,give full play to the resource flexibility of smart buildings,and improve the economy and reliability of the overall operation of the system has become an urgent problem to be solved.This paper considering the cooling characteristics of smart buildings,IES system is considered to meet the building cooling demand.A P2 P electric energy sharing mechanism supported by transactive energy mechanism is established in smart building clusters.and based on the mechanism,according to the energy supply and demand relationship between buildings,the transaction price model of P2 P power sharing in building clusters is established to promote P2 P power sharing.In order to realize the economy and reliability of smart building clusters operation,an economic scheduling optimization model of smart building clusters is established,and the fast ADMM is used to solve the proposed model,so as to obtain the best scheduling scheme.Taking a summer smart building clusters as the research object,the simulation analysis shows that after considering the P2 P energy sharing mechanism,reduces the operating cost of the whole smart building clusters and each building,and reduces the dependence of smart building clusters on external energy,and improves the total electricity satisfaction of the users in the smart building clusters,the flexibility of the whole operation of the building clusters and the absorption level of distributed PV.In addition,the use of IES system to meet the building cooling demand,reduce the energy demand and operation cost of smart building clusters,has good economic benefits.The feasibility and effectiveness of the proposed mechanism and model are verified.
