Considering the interconnection and supply–demand coupling between generation and consumption in the grid, ESS is used to flexibly regulate the flow of electrical energy between
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.
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.
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 .
However, in the actual operation process, if DESs in the aggregation group fail to complete the charge and discharge regulation because of the shutdown failures, the DES aggregation group will bear huge losses (the market will charge double the penalty cost according to the energy deviation).
Based on the principles of the economic access cost to the power dispatch centre, a three-layer architecture for the DES aggregation group is established. And the DESs, commonly distributed in different industrial parks, are aggregated together to form aggregation groups that connect to the power dispatch centre through the data network.
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.
