Peer-to-peer (P2P)-based market transaction method and system for load aggregator

The invention discloses a P2P-based market transaction method and system for a load aggregator, and the method comprises the steps: a load aggregator end issues an initial value of a transaction price for an affiliated consumer end, the consumer ends obtain the price information of other consumer ends through information exchange, independently formulate a power plan, and carry out the transaction of the consumer ends. And when the adjustment result meets the convergence condition, each production and consumption consumer end reports the final power plan and transaction price to the load aggregator end, so that the calculation of the load aggregator end is dispersed to the production and consumption consumer end in the day-ahead stage, and the calculation efficiency of the production and consumption consumer end is improved. Meanwhile, user privacy is protected through limited information exchange, and safety and timeliness are ensured. In the real-time stage, the load aggregator end counts the deviation elec
