面向负荷聚合商的智能合约微服务架构设计及实现

Design and Implementation of Smart Contract Micro-service Architecture for Load Aggregator

在负荷聚合商等需求响应新主体灵活参与电力系统调度的新背景下,区块链智能合约技术为解决多主体间信任缺失问题提供了新思路。然而,现有智能合约部署架构存在运维成本高以及分布式账本交互效率低等问题,与业务逻辑复杂、迭代速度快、多点交互频繁的负荷聚合商优化运行难以兼容。文中提出面向负荷聚合商的智能合约微服务架构,解决将智能合约应用于负荷聚合商参与需求响应的技术瓶颈。针对智能合约微服务架构,搭建了智能合约中继层,提出了基于单一性原则的智能合约领域分解方法,设计了智能合约微服务架构松耦合部署模式。最后,以中国浙江省某大厦和某公寓为例,验证了所提出的智能合约微服务架构可以为负荷聚合商安全、高效、灵活、可信的聚合调控赋能。

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 microservice 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.
