Design of demand response trading platform with security and mutual trust based on blockchain and end-edge-cloud architecture

With high penetration of renewable energy in power system, the demand side response is gradually considered to be an important flexible resource, leading to active participation in electricity market. This article provides a design of demand response trading platform for load aggregators, with integration of end-edge-cloud collaboration and blockchain. Firstly, the end-edge-cloud collaborative architecture enables distributed resources entering electricity market efficiently and realizes the privacy protection of users’ production and operation data, by hierarchical decomposition and coordination of computing and data storage tasks. Meanwhile, certifying and accounting the transaction results through Consortium Blockchain technology can improve security and credibility of transaction on the Platform. Secondly, credit evaluation is taken into account when distributed resources aggregation and instructions decomposition, which encourages the user to strictly execute the contract, thus, mitigate the negative impact for aggregators. Credit evaluation is only carried out with the help of consortium blockchain, providing a secure, efficient and mutually trusted trading ecosystem.
