基于区块链的园区微网分布式电力交易实现机制综述

在开放的电力市场环境下，分布式电源发展迅速。分布式电力交易迎来了前所未有的发展机遇，可有效支撑园区微网运营商实现多能源互补和协同优化，促进园区微网数字化、经济化、低碳化运营。在此背景下，首先对区块链技术和分布式电力市场的契合度进行了分析，并基于分布式电力交易和区块链的特性构建了基于区块链的园区微网分布式交易框架模型。其次，对基于区块链的多元分布式电力交易的实现机制（包括智能合约、共识机制以及跨链技术）进行了分析，最后给出了不同实现机制所面临的风险挑战。

Review on the distributed power transaction implementation mechanism of the park microgrid based on blockchain

In the open electricity market environment, distributed generation has developed rapidly. Traditional centralized transactions face great challenges in meeting the transparency, timeliness and data security of distributed power transactions, in order to help park microgrid operators to achieve multi- energy complementarity and collaborative optimization, and help campus microgrids to be digitalized, economical and low-carbon operations. In this context, model analyzes the fit between blockchain technology and distributed electricity market, and constructs a distributed transaction framework model based on blockchain-based microgrid based on distributed power trading and blockchain. Secondly, the implementation mechanism of blockchain-based multi-distributed power transaction (including smart contract, consensus mechanism and cross- chain technology) is analyzed, and the risk challenges faced by different implementation mechanisms are proposed.
