Power excess consumption voucher transaction method, system and device and medium

The invention relates to the technical field of electricity market transaction, in particular to an electricity excess consumption voucher transaction method, system and device and a medium. Asynchronous processing is performed by introducing a message queue, so that the data volume of uplink evidence storage is reduced while the throughput is improved, and the transaction success rate is improved; through an asynchronous decoupling mode in advance, the response time is shortened, a transaction result is obtained in advance of concentrated bidding or listing transaction in time, the transaction result is confirmed more timely, when the transaction fails, the data rollback efficiency is higher, meanwhile, the legal and equal rights and interests of a market subject are guaranteed, and the user experience is improved. And autonomy and flexibility of market transaction are enhanced. 本发明涉及电力市场交易技术领域，具体地说，涉及一种电力超额消纳凭证交易方法、系统、设备及介质；通过引入消息队列进行异步处理，提升了吞吐量的同时，减少了上链存证的数据量，提高了事务成功率；并通过提前异步解耦的方式，缩短了响应时间，不仅在时效上提前于集中竞价或者挂牌
