Blockchain-Enabled Transactive Method In Distributed Systems Considering Security Constraints

With the power system reform and the increase of distributed energy penetration, effective dispatch of distributed energy faces opportunities and challenges. Traditionally, the centralized power transaction mode has high maintenance cost, low efficiency and untimely settlement. Therefore, it is hard to adapt to the high-frequency and small-scale distributed energy trading scenarios. To this end, this paper mainly proposes a distributed power trading method based on blockchain considering security constraints. The paper first reviews the development history of blockchain technology, and explores the theory of blockchain technology. At the same time, it combines the analysis of distributed energy features and summarizes some requirements for building a distributed energy trading market. Then the mechanism and model of distributed power trading considering security constraints are constructed. Finally, a distributed power trading method based on blockchain is proposed to ensure the transparency of transactions, and to provide smart contracts for distributed power multilateral transactions. Through the example of the Ethereum blockchain, the distributed power trading method based on blockchain proposed in this paper can realize the over-limit correction of power flow and the multilateral trading of power, and realize the digital management of electric energy.
