摘要:

泛在电力物联网的建设，推进电能的生产消费进一步向分布式发展，出现了更多电力自由双边交易。中心化电力交易模式中，市场主体互信度不够，数据安全性不高。提出基于联盟链技术的电力交易方法以解决这些问题，确保交易高透明度、可追溯性与不可篡改性。联盟链分布式存储与数据共识机制确保电力交易系统安全性。保留交易中心的监管权限、将调度中心安全校核与电网输送电能环节纳入电力交易，提升联盟链技术应用于电力交易业务的可行性。最后设计交易平台中发、用电多方合作博弈交易情景，多发电方共同完成电力需求。该方法有利于灵活调整交易电量，增加合作收益，避免单个发电方无法满足规定时间内过大电力需求的隐患，为未来的弱中心化电力交易模式提供新思路。

Abstract:

With the construction of ubiquitous power internet of things, there will be more free bilateral energy trading in the future. In the centralized electricity trading mode, the mutual trust of market participants is insufficient, and the data security is not enough. Consortium blockchain is expected to solve these problems. This paper proposes a power trading method based on consortium blockchain technology to ensure high transparency, traceability and irreversible modification of power trading. The regulatory authority of the trading center is retained, the security check of the dispatching center and the power transmission of the power grid are integrated into the power transaction, and the system application feasibility is improved. Finally, a multi-party cooperative game trading scenario is designed, and a single power demand can be completed by multiple power generation parties. It is conducive to the flexible adjustment of trading power and the increase of cooperation revenue, avoiding the hidden dangers that a single power generator cannot meet the excessive power demand within a specified time. It provides new ideas for establishing of a weak centralized power trading model for the power market. This work is supported by National Key Research and Development Program of China (No. 2017YFB1201002).

Key words: ubiquitous power internet of things power trading consortium blockchain weakly centralized distributed storage
