A vehicle-network interconnection optimization control method based on a market clearing price auction mechanism

Abstract

The invention discloses a vehicle network interconnection optimization control method based on a market clearing price auction mechanism. The method includes: S1, submitting the initial auction information set b<n><(0)>; S2, the grid transaction control center determining the initial electricity price set p (0) according to the auction information set and the optimization objective; S3, accordingto the determined electricity price, adjusting respective auction information, and reporting auction information b<n><(k)>again;; S4:, according to the re-submitted auction information set and the optimization objective, the grid transaction control center determining the k-th electricity price set p (k); S5, judging whether p (k)-p (k-1)>epsilon stop, if yes, updating times k=k+1, and returning to step S3; otherwise, proceeding to step S6; S6, obtaining a charging strategy b<n><*>. The present invention utilizes a power price incentive mechanism to guide the electric vehicle user to arrange the charging time and charge quantity reasonably, which has good grid compatibility. Electric vehicle users do not need to provide their own sensitive parameters to the power grid system through the auction mechanism, the privacy of the users is protected, and the electricity price is determined through auction information to ensure the rationality of the electricity price.

Description

technical field [0001] The invention relates to the technical field of electric vehicles, in particular to a vehicle-network interconnection optimization control method based on a market clearing price auction mechanism. Background technique [0002] With the rapid development and popularization of electric vehicles, a large number of electric vehicles are connected to the power grid as new loads, which will inevitably have an impact on the current power grid, and even affect the stability, safety and reliability of the entire power grid. At present, the operation of charging electric vehicles connected to the grid is disordered and uncontrolled, that is, the charging service is carried out according to the electricity sales price stipulated by the government. When electric vehicle users need to charge, they only need to connect to the charging pile to carry out the charging operation. The charging amount and charging time are determined by electric vehicle users themselves,...

AI Technical Summary

Problems solved by technology

The power increment of this part was not considered in the design and construction of the original power grid, and the centralized and disorderly charging operation will cause the regional power grid to run overloaded

If the traditional expansion method is adopted, there will be disadvantages such as high investment cost and difficult transformation

[0005] In addition, large-scale electric vehicles are connected to the grid for disorderly and uncontrolled charging operations. For grid managers and electricity sales companies, they only complete the behavior of passive electricity sales, and do not obtain more valuable, Meaningful information, data, etc.

Compared with the intelligent development of the grid, the disorderly and uncontrolled charging of large-scale electric vehicles is not conducive to the intelligent development of the grid, and at the same time increases the workload of grid operation and maintenance.

[0006] In the traditional charging mode, electricity retail companies can read various private information of electric vehicle users, such as the user's driving route, driving preference, frequented places, etc., which is not conducive to privacy protection and information security
