This paper investigates the collaborative energy management problem for integrated energy system, where an asynchronous and dynamic event-triggering communication strategy based distributed gradient algorithm is proposed to solve this problem. By introducing external auxiliary variable and designing effective triggering mechanism, this method can enable each participant sharing information with neighbors in a discrete and asynchronous communication fashion if only necessary. In this way, the continuous algorithm can be implemented in a discrete communication fashion. Meanwhile, this method does not rely on global clock synchronization, resulting in enhanced flexibility. In addition, the global convergence of the proposed algorithm is also proved in theory. Finally, the simulation results show the effectiveness of the proposed method.
