Distributed Optimal Dispatch of Integrated Energy System Considering Privacy-Preserving

Abstract— To solve the problem of information privacy between integrated energy systems (IES) for unified operation, a cross-regional distributed coordination control strategy under incomplete information conditions is proposed. Firstly, the incomplete information conditions are explained based on the types and characteristics of cross-regional multi-energy coordination, and the coupling port can be used to exchange part of the information for multi-agent autonomous coordination. The implementation method adopts the alternating direction method of multipliers (ADMM) and optimizes iterative method. Secondly, combined with the principle of decentralized consistency, the ADMM global consistency framework is constructed, and the system is decomposed at inter-regional connection lines and pipelines in combination with boundary replication. Then, the objective function and constraint conditions are decomposed according to the region, and the convergence speed of the calculation process is further accelerated from the two aspects of model linearization and variable penalty parameters. Finally, the feasibility of the algorithm and the effectiveness of the proposed strategy are analyzed and verified with a simulation case.
Index Terms— integrated energy system (IES), alternating direction method of multipliers (ADMM), distributed optimal dispatch, information privacy.
