Problems solved by technology

[0003] Under the large-scale application of electric vehicles, their charging demand will have an adverse impact on the power grid. For example, the charging demand of electric vehicles may increase the peak load of the power grid, and even exceed the capacity of the local distribution network. The power grid needs to a

Embodiment Construction

[0091] The present invention will be further introduced below in conjunction with the accompanying drawings and specific embodiments.

[0092] The invention starts with the influence of the electric vehicle on the power grid, and analyzes the interaction relationship between the electric vehicle and the power grid. On this basis, in the context of demand response technology, combined with the charging scenarios and control modes of electric vehicles, the interactive control objectives of electric vehicles and power grids are proposed. According to the control objectives, the interaction architecture of electric vehicles and power grids is established, and the Electric vehicle users, intermediate management platforms, and distribution network management platforms have established information models and designed control strategies at each level.

[0093] The system hierarchical structure of the present invention is as figure 1 As shown, it involves three types of electric vehic...

Abstract

The invention discloses an electric automobile and grid interacted and coordinated orderly charging control method. Multi-level multi-object control strategies are adopted, and electric automobile orderly charging and charging and discharging control strategies are divided into multiple levels according to different control main bodies and control objects. When an electric automobile is under the control of a plurality of main bodies to realize the control object at each level, each level is constrained by the control objects at an upper level and a lower level. When all control levels exist at the same time, the control ranges and the control objects of all levels have a mutually constrained relationship. The orderly charging control method disclosed by the invention can realize electric automobile orderly charging and grid interaction, reduce the adverse influence of the electric automobile to the grid and can promote the popularization and application of electric automobile charging facilities by supporting the operation of the grid by using the charging flexibility and adjustability features and the energy storage capacity of the electric automobile. The method is simple to operate, is convenient to manage, has excellent performance and is convenient and practical to use for electric automobile and grid interacted and coordinated orderly charging control.

Description

technical field [0001] The invention relates to an orderly charging control method for interactive coordination between an electric vehicle and a power grid. Background technique [0002] Large-scale application of electric vehicles will have a profound impact on the power grid. On the one hand, uncontrolled charging of electric vehicles will increase the peak load of the power grid, reducing the reliability and operating efficiency of the power grid. resource. At present, my country's power distribution network structure is weak, the degree of automation is low, and the dispatching methods are backward. The management of electric vehicles that are widely distributed on the power consumption side and have strong randomness will pose challenges to the monitoring, communication and control capabilities of the power grid. Recognize the impact of electric vehicles on the grid, use smart grid technology to make electric vehicles an integral part of the grid, and consider the in...
