Widely distributed type electric vehicle control method

Abstract

Disclosed is a widely distributed type electric vehicle control method. The control method comprises a widely distributed type electric vehicle cluster of an integrated vehicle-mounted intelligent EV matrix control system in an application layer, multiple regional active type EV matrix distribution and monitoring systems in a service layer, power distribution automatic sub stations which are corresponding to the regional active type EV matrix distribution and monitoring systems for communication and coordination control, a power distribution automatic main station which is used for managing and controlling the regional active type EV matrix distribution and monitoring systems and the power distribution automatic sub stations, and a power distribution dispatching automatic system and a power transmission dispatching automatic system in a platform layer. The system has the distributed calculation characteristic, and supports the plug and play function; the system is based on open and interconnecting, free and equal principles; a charge-discharge requirement can be directly issued or responded between any one point and any other one or more points in the electric vehicle cluster under a normal condition without requiring intervention from the power supply side; when the requirements in the application layer in the system are subjected to an extreme condition, and all the application layer requirements in the region cannot be satisfied mutually, the regional active type EV matrix distribution and monitoring systems participate in the coordination and allocation; and furthermore, coordination, control and dispatching can be applied to the higher power distribution automatic main station, the power distribution dispatching automatic system and the power transmission dispatching automatic system.

Description

technical field [0001] The invention is a widely distributed electric vehicle control method, which belongs to the application of intelligent control technology in power systems, and is especially suitable for the field of access, control and utilization of widely distributed electric vehicles in smart grids. Background technique [0002] Against the backdrop of rising fuel prices, the gradual depletion of fossil energy, and the intensification of global warming, electric vehicles replace oil with electricity, and as an important means to solve transportation, energy, and environmental problems, they have gradually attracted international attention. Form large-scale markets in North America, Europe, Japan and other regions or countries. A large number of electric vehicles put into operation will have a great impact on the power system. The harmonics generated by the electric vehicle charging and discharging machine will deteriorate the power quality of the local grid; at th...

Problems solved by technology

However, in the above methods, there are deficiencies: that is, neither of them can obtain the demand information of electric vehicles in advance, and all the scheduling, allocation, and control are based on the demand of electric vehicles, or using specific mathematical methods to predict or estimate The demand for electric vehicles; the information flow direction of electric vehicles is simplex mode, that is, from a single electric vehicle node to the power supply side to the dispatching side, then from the dispatching side to the power supply side to a single electric vehicle node, between each node, and From each node to the power supply side, the demand information between each other is isolated and closed
