Abstract— With the development of energy Internet, the energy coupling relationship between multiple regions is increasingly strengthened. How to guarantee the safety of the information between regions to realize the distributed optimal scheduling of multi-region system has become a crucial problem. In this paper, a completely distributed optimal scheduling method of multi-region integrated energy system (IES) based on alternating direction method of multipliers (ADMM) is proposed to solve the problems of information exchange obstacles and data leakage in centralized scheduling method. Firstly, a typical distributed scheduling model consisting of three park-level IESs is established to analyze inter-regional coordination optimization mechanism. Then, using a distributed solution method based on ADMM that can cancel the upper scheduling center to protect the safety of the data information of each region. Furthermore, this method assigns the calculation work of multipliers to interconnected regions to replace the data processing center. Before each region starts the next iteration, the interconnected regions are responsible for updating the multipliers, thus realizing the completely distributed scheduling strategy. Finally, the proposed method is adopted to solve the optimization problem of the three interconnected IESs and compared with the traditional centralized scheduling method to verify its effectiveness and correctness.

Index Terms— Alternating direction method of multiplier, multi-region, integrated energy system, completely distributed optimal scheduling.
