Weakly-centralized Transaction Strategy of Multi-microgrid Integrated Energy System from the Perspective of Energy Market

Abstract

The research on the market transaction mechanism of the multi-microgrid integrated energy system will help promote new energy consumption and a low-carbon economy. A weakly-centralized transaction strategy for a multi-microgrid integrated energy system is proposed. First, a weakly-centralized transaction mechanism for multi-microgrid integrated energy markets is proposed under a two-layer operation framework. Second, the multi-microgrid integrated energy market subject operation optimization model, bidding model, and market clearing model under this transaction mechanism are constructed. Further, the ADMM (Alternating Direction Method of Multipliers) algorithm is used to solve the proposed market energy optimization model. The proposed strategy takes into account the characteristics of decentralized decision-making and free competition in the energy market, and the privacy of each transaction entity is further guaranteed. Finally, the effectiveness of the proposed strategy is verified by examples.
