Transactive control and coordination of multiple integrated energy systems

Abstract

This paper proposes an energy management and coordination method based on transactive control for multiple integrated energy systems. The method applies a hierarchical architecture. In the lower level, each integrated energy system is modelled using energy hub, and an autonomous optimization is implemented locally. In the upper level, all integrated energy systems are coordinated using transactive control, realizing a distributed optimization. Then, the two-stage energy management method is adopted for the day-ahead and real-time stage. At last, a case study validates the advantage of coordination and proves the proposed method to be able to deal with the prediction error of loads and renewable energy resources and other unexpected events. Compared with the centralized method, this method has advantages in scalability, flexibility and privacy preserving.
