基于区块链的微电网电力交易匹配机制

Power transaction matching mechanism of microgrid based on block chain

针对分布式微电网新能源电力交易问题,基于主体的历史交易完成比提出一种适用于交易的匹配策略。将匹配度量化为对实体信用与电力售价的考察,并借助区块链实现信用数据的有效共享与周期评估。当消费者在进行购电行为收到不同生产者的电价信息时,可从区块链账本中得知该生产者的交易信用值,并筛选出合适的交易方。算例分析表明:所提策略能够有效量化信用,结合售电价格匹配到最适合的交易方。

Aiming at power transaction problem of renewable energy in microgrid,a matching strategy suitable for transaction is proposed based on historical transaction completion degree.The matching degree is quantified into the investigation of entity credit and power selling price,and the block chain is used to realize effective sharing and cycle assessment of credit data.When the consumer receives power price information of different producers when buying power,he can know the producers’transaction credit from block chain account book and select suitable transaction party.Example analysis shows that the proposed strategy can effectively quantify credit,and match the most suitable transaction party combing with power selling price.
