Distributed energy transaction matching method based on energy network constraints and multiple knapsack problems

The invention belongs to the field of distributed energy transaction. The distributed energy transaction matching method based on energy network constraints and multiple knapsack problems comprises the following steps: 1) by designing an augmented optimization model of energy scheduling, constraining the transaction volume of a user to be a relatively small value of a declaration volume and an energy network limit volume, and adding a safety check link for distributed transaction; and 2) based on a traditional single knapsack model, designing a multi-knapsack model which is more consistent with point-to-point transaction by taking the maximum market transaction value as a target, and performing transaction matching on a plurality of buyers and sellers. According to the method, an idea is provided for connection of energy distributed transaction and actual physical scheduling, a universal and efficient matching model is provided for a point-to-point distributed transaction market, and the method has relatively
