摘要：
In the new background that load aggregators and other new demand response entities flexibly participate in power system dispatching, the blockchain smart contract technology provides new ideas for solving the problem of lack of trust among multiple entities. However, the existing smart contract deployment architecture has problems such as high operation and maintenance costs and low efficiency of distributed ledger interaction. It is difficult to be compatible with optimized operation of load aggregators with complex business logic, fast iteration speed, and frequent multi-point interaction. This paper proposes a smart contract micro-service architecture for load aggregators to solve the technical bottleneck of applying smart contracts to load aggregators to participate in demand response. Aiming at the smart contract micro-service architecture, the smart contract relay layer is built, the domain decomposition method for smart contracts based on the principle of unity is proposed, and the loosely coupled deployment mode of the smart contract micro-service architecture is designed. Finally, taking a building and an apartment in Zhejiang, China as an example, it is verified that the proposed smart contract micro-service architecture can empower the load aggregator with safe, efficient, flexible and credible aggregation control. © 2022 Automation of Electric Power Systems Press.
