Heat-electricity joint bidding strategies for intelligent buildings in intelligent building cluster

Abstract With the improvement of intelligent buildings (IBs), the problem of energy consumption in IB integrated energy system is becoming more and more serious. Multiple IBs form an intelligent building cluster (IBC) through energy coordination and complementation and energy mutual gathering. How to promote the sustainability and flexibility of energy trading and improve the initiative of IBs to participate in energy trading in the IBC is very challenging. It is necessary to study the operation framework of energy trading in IBC and the bidding strategies of IBs. To this end, this paper proposes a heat-electricity joint bidding strategy for IBs in IBC. First, we put forward an operating framework of heat-electricity joint trading for IBC, including the basic operation structure and the organization process of heat-electricity joint trading. Secondly, a heat-electricity joint bidding model for IBs in IBC is established. Finally, the effectiveness of the trading mode and the impact of joint and independent heat-electricity trading on the trading results are analyzed. The results show that the proposed method can improve the overall operating economy of IBC by 2.4% comparing to the heat-electricity independent bidding.
