Abstract

A grid frequency dynamic response device of an electric car charging equipment comprises a frequency detection module and a response control module, wherein the frequency detection module is electrically connected with an accessed grid, the response control module is electrically connected with an electric car an electric car, the frequency detection module is used for detecting the abnormal frequency of the accessed grid, and after receiving the data which are sent by the frequency detection module and are abnormal in frequency, the response control module carries out frequency response according to a response control strategy through data processing. The grid frequency dynamic response device of the electric car charging equipment is simple in structure, low in manufacturing cost, high in response speed, capable of achieving bi-directional regulation of energy and information, and high in comprehensive energy efficiency, the charging and discharging efficiency of the batteries can reach 80%, and the grid frequency dynamic response device of the electric car charging equipment can achieve alternation between up regulation and down regulation without limitation in the frequency response process, and is high in reliability of motions.

Description

technical field [0001] The invention relates to the electrical field, in particular to a device for dynamically responding to grid frequency for electric vehicle charging equipment. Background technique [0002] The birth of V2G technology realizes the two-way exchange of energy and information between electric vehicles and the grid, making electric vehicles no longer just a power user, but an active participant. Through a reasonable control strategy, the charging and discharging of electric vehicles can be properly adjusted and controlled to realize the two-way interaction of energy between the grid and users, making the power supply system more stable and reliable, and improving the power quality of the grid and its operating economy. [0003] There is following defective in prior art: [0004] 1) The response speed is slow. Due to the influence of the life of the mechanical components of the power unit, the response speed is generally the fastest at the second level; ...
