Distributed Energy Management Strategy for Integrated Electric-heat System Considering Building Height

To realize the flexible operation of an integrated electric-heat system (IEHS) with building clusters, a distributed energy management strategy for IEHS that considers building height is proposed in this paper. First, based on the building's thermal inertia and vertical heating structures, a detailed thermal dynamic model of the building considering building height is established, and it is integrated into the IEHS operational model by comprehensively considering the constraints of electrical and thermal systems. Then, to minimize the total cost of energy consumption, an energy management method for IEHS that considers building height is proposed by using the thermal storage properties of buildings and complementary properties of heat sources. Finally, to increase the solution efficiency and ensure the privacy of information between different subjects, a three-stage accelerated alternating direction method of multipliers (TSA-ADMM) is proposed, which decomposes the original problem into sub-problems of distribution network and heat network for the distributed solution. The results show that the proposed strategy can reflect the vertical imbalance in the building heating process and achieve the globally optimal energy management of IEHS with building clusters while guaranteeing the user's comfort with temperature demand and the privacy of different subjects' information.
