Virtual power plant transaction mechanism based on main-side chain structure

The invention discloses a virtual power plant transaction mechanism based on a main-side chain structure, and relates to the technical field of electric power management, comprising the following steps: 1, a pre-transaction stage; 2, in a side chain transaction stage, aggregator nodes in a side chain comprise a complete agent type aggregator and an autonomous transaction type aggregator; the complete proxy aggregator realizes internal pricing according to the internal load prediction information and the power generation prediction information, and an internal distributed resource main body responds to a price signal of the complete proxy aggregator through an intelligent electric meter; the side chain transaction participated by the autonomous transaction type aggregator performs continuous two-way auction transaction; 3, in a main chain transaction stage, when electric quantity surplus or electric quantity shortage exists after the transaction in the side chain is completed, participating in main chain trans
