Consortium Blockchain-Based Microgrid Market Transaction Research

Abstract

The microgrid trading market can effectively solve the problem of in-situ consumption of distributed energy and reduce the impact of distributed generation (DG) on the grid. However, the traditional microgrid trading model has some shortcomings, such as high operation cost and poor security. Therefore, in this paper, a microgrid market trading model was developed using consortium blockchain technology and Nash game equilibrium theory. Firstly, blockchain container is used to authenticate the users who want to participate in the transaction. Then, the pricing system collects and integrates transaction requests submitted by users, then formulates transaction pricing strategy of microgrid using Nash equilibrium theory. Finally, the price, trading volume, and user information are submitted to the blockchain container for transaction matching to achieve the transaction. After the transaction is completed, its related information is recorded in the hyperledger and the dispatch system is called. The scene simulation was implemented on Fabric 1.1 platform and the results analyzed. Results show that the trading model proposed in this paper greatly reduces the cost of electricity purchase and improves the benefits of electricity sales. Besides, the model is far more capable of handling transactions than the models based on Bitcoin and Ethereum.

Ring signature and improved multi‐transaction mode consortium blockchain‐based private information retrieval for privacy‐preserving smart parking system

“…In addition, they also have the risk of remote hijacking attacks and distributed denial‐of‐service (DDoS) attacks that have the possibility of converting the parking services unavailable 13 . At this juncture, a potential blockchain technology with the merits of trust, security, and decentralization needs to be utilized for different applications in order to resolve the limitations existing in the centralized solutions of conventional smart parking systems 14 . In specific, blockchain is essential for facilitating significant smart parking systems as it possesses the characteristics of transparent, distributed, and immutable public ledger structured as the blockchain with a managed collection of miners or validators 2 …”

An Improved Retrieval Method for Multi-Transaction Mode Consortium Blockchain

“…The consortium blockchain is one of the three forms of blockchain, which is characterized by a weak centralized network. It has been widely used in many fields, such as asset, credit, time proof of key events, existence proof, and trading market [1][2][3]. The Multi-Transaction Mode Consortium Blockchain [4] was developed on the basis of retaining some original characteristics of the blockchain, realizing transaction type diversification, virtual nodes, and block cloud storage, allowing attached transaction data, etc., which makes the application of blockchain technology more flexible.…”

“…According to the problem that the retrieval efficiency will decline with the increase of "Block Name File", combined with the excellent read-write performance of the Redis memory database, a fast retrieval method of "block name collection" under Redis cache is proposed. 3.…”
