A coordinated operation model for multiple community integrated energy systems and hybrid distribution system based on hierarchical decentralized scheduling

With a significant increase of load type and distributed generator permeability in multiple community integrated energy systems (CIESs), a hybrid distribution system (HDS) including AC/DC power network and heat network is required to satisfy multi-energy demands. This paper presents a detailed model for CIES and HDS to realize cascade utilization of multi-energy. To overcome the profit conflicts among HDS and multiple CIESs, a coordinated operation model based on hierarchical decentralized scheduling is proposed. Furthermore, the alternating direction method of multipliers (ADMM) algorithm is used to solve this coordinated model. Finally, the proposed model and method have been verified on a test HDS, which consists of an IEEE 33-bus AC power system coupling with a 4-bus DC power system and a 6-node heat system, and multiple CIESs which locate in Jiangsu Province, China.
