in step S3-4, the EIDA algorithm includes the following steps:
s3-4-1: inputting the energy states and energy bids of the charging PHEV and the power supply PHEV into an energy fog node;
s3-4-2: initializing iteration parameters, and initializing optimal energy bidding according to initial energy bidding;
s3-4-3: calculating optimal energy distribution according to the current optimal energy bidding, and matching energy demands and supplies of the charging PHEV and the power supply PHEV;
s3-4-4: updating the optimal energy bidding of the charging PHEV and the power supply PHEV according to the current optimal energy distribution, and updating the iteration times;
s3-4-5: judging whether the updated current optimal energy bidding convergence meets the requirement, if so, entering a step S3-4-7, otherwise, entering a step S3-4-6;
s3-4-6: judging whether the current iteration number is larger than the maximum iteration number, if so, entering a step S3-4-7, otherwise, entering a step S3-4-3;
s3-4-7: and combining the current optimal energy allocation and the current optimal energy bidding into a decision and outputting the decision.
3. The transaction method according to claim 2, wherein in step S3-4-5, the convergence criterion is formulated as:
in the formula, CB and CS are convergence judgment criteria;
bidding for charging the energy of the PHEV;
bidding on energy for powering the PHEV; epsilon is a convergence condition constant; and t is the iteration number.
