Multi-agent Cooperative Optical Storage Operation Strategy Based on Demand Response

With the advancement of market-oriented reform in distribution networks, optical storage aggregators have gradually become the main market participant. In this context, to ensure the economy and security of distribution grid operation and mitigate issues such as incentive shifting triggered by time-of-use prices under high penetration rates, a multi-body synergistic optical storage operation strategy is proposed with demand response taken into account. Firstly, a shadow price theory and corresponding model are developed by introducing a bootstrap price on the basis of time-of-use prices. This theory and model have the ability of more accurately reflecting the actual situation of the power market and improving the adaptability of the optical storage operation strategy. The introduction of the bootstrap price enables better market participation for the optical storage aggregator. On this basis, a two-layer optimization model for the distribution network operation and the optical storage aggregator is established with the objective of the optimal economy of each subject. Using this model, the balance between both the operation demand of the distribution network and the economic objectives of the optical storage aggregator can be effectively achieved to realize the synergistic operation of multiple subjects. Finally, the effectiveness of the proposed model is verified through arithmetic examples.
