The Distributed Coordinated Operation Strategies of Distribution Network and Multi-Micro Energy Grids

With the proliferation of micro energy grids, the interactive operation issue between distribution network and micro energy grids has been a burning question. This paper proposes a coordinated operation model from the perspective of social welfare. In order to protect the privacy of each participant, the Alternating Direction Method of Multipliers (ADMM) is employed to decompose the original centralized optimization model into distributed local optimization models. A distributed interactive algorithm is also proposed to solve the optimal operation strategies. Simulation results on the modified IEEE 15-node system show that the proposed model can protect the privacy of participants and solve the operation strategies efficiently. Besides, the coordinated operation of the distribution network and micro energy grids can realize security and economic operations of the whole system.
