Abstract

Background

The coupling of multiple heterogeneous energy sources in an integrated energy system has led to difficulties in coordinating the optimal scheduling of various energy sources. As a typical cyber-physical system, the development scale of an integrated energy system is limited by the communication bandwidth.

Objective

A coordinated optimal scheduling method for integrated energy system based on finite-time event-triggered consensus algorithm is proposed in this paper to achieve the optimal operation of an integrated energy system and lower the burden on the communication network.

Methods

In this paper, the optimal scheduling model of integrated energy system is established, and the finite-time consensus algorithm is applied to solve the model, so that the operating costs of various energy sources can reach the optimal solution within a finite time. Then, a discrete system communication scheme is established so that neighbor nodes exchange state information only at the triggering instants. The stability of the system is analyzed using the Lyapunov stability theory, and it is verified that the system does not exhibit the Zeno phenomenon. Finally, the effectiveness of the proposed optimal scheduling method is verified by case analysis.

Results

The results show that the method can achieve the optimal operation of integrated energy system and effectively reduce the number of communications between neighbor nodes, lowering the burden on the communication network.

Conclusion

An integrated energy system composed of electric-heating-gas-cooling is given to verify the feasibility and effectiveness of the proposed method.
