A Priority Decision Making Based Bidding Strategy for Interactive Aggregators

This paper proposes an interactive bidding strategy for smart distribution networks with clustered aggregators to effectively coordinate the energy and profit of each entity. In the proposed one-leader n-follower bidding model, there are two levels, where the upper level stands for the distribution operator (DO) to secure the operation quality and bid with energy aggregators (EAs), and the lower level represents each EA to bid for interactive energies with the DO and other EAs. The proposed interactive bidding mechanism takes advantages of both renewable generation and energy storage system into account, where the priority-based decision making is applied to the lower level to elaborately map the bidding mechanism and lead each EA's market interaction. Case studies on the IEEE 33-bus test feeder and a practical distribution grid in China demonstrate the effectiveness of the proposed methodology.
