Abstract

The invention discloses an electric automobile charging optimization system for the automatic regulation and control and compensation of a power grid, and the system comprises an electric automobile;a charging station which is used for charging the electric automobile; the power grid which is connected between the charging station and the electric automobile, wherein the power grid is connected with the charging station through a real-time information interaction system; a PID regulator which is connected between the power grid and the real-time information interaction system, and is used forachieving the output compensation; and a two-stage bidirectional DC/DC converter which is connected between the electric automobile and the power grid. The system meets the excellent power supply demands of a user, and achieves the reliable and continuous power supply through the ordered discharging of an electric automobile group in a station during an emergency fault of the power grid.

Description

technical field [0001] The invention belongs to the field of power grid regulation and management, and in particular relates to an electric vehicle charging optimization system and method thereof for automatically regulating and compensating power grids. Background technique [0002] The global energy crisis is happening, the non-renewable energy such as oil is exhausted day by day, the greenhouse effect and air pollution are getting worse day by day, and the issue of sustainable utilization of resources has become the focus of governments of all countries. The government and automobile companies also realize that energy issues are an important criterion for the development of future automobile technology, and the idea of ​​developing electric vehicles driven by new energy came into being. Among them, pure electric vehicles have opened up a new century for the automobile industry. Electric vehicles (Electric Vehicle, EV) are highly regarded for their excellent characteristic...
