This paper presents a detailed review of the existing literature on peer-to-peer (P2P) energy trading considering market architectures, trading strategies, and enabling technologies. P2P energy trading enables individual
The transaction process of energy storage participating in auxiliary services can be divided into four stages: initialization stage, pre-submission stage, P2P transaction stage and payment delivery stage.
Conclusion The market-oriented trading mode and mechanism of shared energy storage on the grid side based on block chain is studied in this paper. Through the complete transaction framework, mode and process, energy storage participating in peak regulation and frequency modulation is deployed on the block chain.
In the aspect of key technology, block chain can be used to improve the computing power and slow response speed that may exist in power transaction. Table 1. Blockchain-based power trading advantage table. 3. Application of energy storage in auxiliary service market transaction 3.1. Domestic policy support
As an emerging technology, energy storage can improve the flexibility and security of power system, promote the consumption of clean energy and reduce the cost of energy use. There are still some problems such as information asymmetry and jumbled transaction mechanism when energy storage participates in auxiliary service transactions.
Status of participation of energy storage in ancillary services The application of energy storage in auxiliary service of power system is mainly reflected in five aspects: peak regulation, frequency modulation, reactive power compensation, standby and black start.
Shenzhen Shekou uses the alliance chain to build the energy block chain project, which is composed of clean energy providers at the power generation side and clean energy recipients at the power side, and uses the block chain to realize microgrid energy trading . 2.3.
