The development of cogeneration, distributed generation, information and communication technology has facilitated the application of integrated community energy system (ICES). However, some ICESs may lack operational flexibility due to the strict constraints of community heating system (CHS), which reduce the energy efficiency of ICESs. To solve this problem, an optimal dispatch model of ICES considering energy flexibilities in pipelines and buildings is proposed, in which the thermal dynamics of pipelines and buildings are described by node method and equivalent thermal parameter (ETP) method. The objective of the proposed dispatch method is to minimize the daily operation cost of ICES. What’s more, renewable energy accommodation cost and power purchase cost are both analysed to verify the improvement of ICES flexibility. It is demonstrated that the proposed method can unlock the flexibility of CHS and improve the energy efficiency of ICES.
