Can distributed energy storages participate in energy trading through aggregation?However, individually accessing every distributed energy storage to the dispatch centre results in a high cost and low efficiency, which needs to be improved by connecting through the aggregator. To this end, this paper proposes a regulation mode and strategy for distributed energy storages participating in energy trading through aggregation.
What are the key features of a energy distribution system?Methodology/results: We employ a stylized model that captures essential features of an energy distribution system, including convex costs, stochastic demand, storage efficiency, and line losses. Using dynamic programming, we optimize storage operations and derive value function properties that are key to analyzing the storage investment decisions.
Can power spot market regulation guarantee economic profits of distributed energy storages?Finally, case studies under multiple scenarios of power spot market verify that the regulation mode and strategy can effectively guarantee the economic profits of distributed energy storages by setting aggregation groups and reasonable risk preference coefficients.
How do we find optimal energy storage aggregation centres?First, the optimal centres of distributed energy storages are searched as the aggregation centres according to the electrical distance distributed by the energy storage, and the model of each distributed energy storage aggregation group is established.
What is real-time arbitrage of distributed energy storage (des)?This is especially true for the distributed energy storage (DES), which can use its fast adjustment characteristic to carry out real-time arbitrage for improving its own economic profits [4, 5]. At present, the real-time arbitrage of DES through the power spot market is mainly concentrated in places such as the USA, Europe and Australia .
How des aggregation can improve power spot market in China?In the future development, as power spot market is gradually opened to the user side in China, the DES aggregation group can participate in market competition and peer-to-peer transactions, which can further take advantage of the flexible adjustment characteristics of DESs and support the balance of power supply and dema
