Renewable energy excess consumption voucher distribution method, system and device and medium

The invention relates to the technical field of energy utilization, in particular to a renewable energy excess consumption voucher distribution method, system and device and a medium. The method comprises the following steps: firstly, establishing a renewable energy excess consumption voucher distribution model according to acquired to-be-distributed order information and to-be-distributed voucher information; then calling a particle swarm algorithm, and solving the renewable energy excess consumption voucher distribution model to obtain a voucher distribution scheme; and finally, according to a greedy strategy method and a voucher splitting method, adjusting the voucher distribution scheme to obtain a corrected voucher distribution scheme. The problem of excessive consumption voucher distribution in large-scale high-concurrency transactions is solved, the system operation pressure is reduced, and the system response speed and the operation efficiency are improved. 本发明涉及能源利用技术领域，具体地说，涉及一种可再生能源超额消纳凭证分配方法、系统、设备
