Abstract: With the development of integrated energy systems, the penetration of large-scale renewable energy gradually changes the energy structure of power systems. To solve the increasing random load disturbances faced by integrated energy systems and reduce power fluctuation, the optimal power regulation method of multiarea integrated energy systems is studied in this paper. Meanwhile, the intervention of communication network brings uncertainties to integrated energy systems. For example, time-delays and packages loss affect the stability and dynamic performance of integrated energy systems. Considering the above factor, a novel modeling approach for multiarea integrated energy systems based on distributed collaborative event-triggering mechanism is put forward. The stability of integrated energy systems is analyzed by Lyapunov stability theory, and a design method for distributed collaborative optimization regulator of multiarea integrated energy systems is derived. This method integrates transmission mechanism with physical system design to achieve real-time perception and dynamic control. Numerical simulation verifies that the co-design method smooths the fluctuation of system power under random load disturbances, improves the dynamic performance of multiarea integrated energy systems, and enhances data transmission efficiency.
