基于智能合约的区域能源交易模型与实验测试

区域能源交易主要通过集中式的交易服务平台提供买卖交易合同,配合电网进行电力供应与输送,存在服务成本高、交易效率低、用户隐私缺乏安全保障等问题。通过分析区域能源交易的特点,以区块链的智能合约、分布式记账、点对点交易等技术为基础,构建了基于区块链的区域能源交易基础应用结构。给出基于智能合约的区域能源交易模型,区域内部的产消者可以通过区块链网络发送交易请求,通过双向拍卖定价机制得出清算价格,回应交易请求,触发状态机执行合约,完成交易。给出了基于智能合约的区域能源交易流程,使用以太坊和超级账本等区块链网络搭建实验环境,模拟多个电能产消者参与的区域能源交易,验证上述方法的可行性。

Regional Energy Transaction Model and Experimental Test Based on Smart Contract

Regional energy trading mainly provides sales and purchase transaction contracts through a centralized trading service platform, and cooperates with power grid for power supply and transportation. There are problems in it such as high service cost, low transaction efficiency, and lack of user privacy. Based on analysis of the characteristics of regional energy trading, this paper builds a basic application structure of regional energy trading based on blockchain smart contract, distributed accounting, and peer-to-peer trading. This paper proposes a regional energy trading model based on smart contracts. The prosumer within the region can send transaction requests through blockchain network, obtain clearing price through two-way auction pricing mechanism, respond to the transaction request, and trigger state machine to execute the contract, thus completing the transaction. Taking the regional energy trading of multiple producers and consumers in the park as an example, the regional energy trading process based on smart contracts is given. This paper presents a regional energy trading process based on smart contracts, using a blockchain network such as Ethereum and Hyperledger Fabric to build an experimental env ironment to simulate regional energy transactions involving multiple energy prosumer, verifying feasibility of above method.
