Embodiment Construction

[0028] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0029] In order to enable those skilled in the art to better understand the solutions of the embodiments of the present invention, the embodiments of the present invention will be further described in detail below in conjunction with the drawings and implementations.

[0030] The invention proposes a consistency-based LVSM distributed cooperative control strategy for electric vehicle groups connected to a distribution network, and the control strategy includes two parts: local control and distributed secondary control. Local control uses LVSM technology to control electric vehicles, providing electric vehicles with a grid-friendly interface and realizing interaction with the grid. In the distributed secondary control, the voltage and reactive power information of each node is updated in real time based on the consensus algorithm, and the deviation between the...

Abstract

The invention discloses a distributed cooperative control method for load virtual synchronous machine based on consistency. The method comprises the steps of: controlling an electric vehicle by adopting a load virtual synchronous machine technology to supply a grid-friendly interface for the electric vehicle to achieve interaction with the power grid; then, constructing a distributed communicationnetwork to update the voltage and the reactive information of each node in real time based on the dynamic consistency algorithm, achieving information interaction between adjacent electric vehicle type LVSMs in a low-bandwidth communication mode to obtain a global average voltage estimation value the reactive output reference value of each electric vehicle type LVSM and achieve the purpose of reasonably distributing the reactive output of the electric vehicle type LVSMs while compensating the voltage of the power grid. The method provided by the invention achieves interaction of the electricvehicle participating in the power grid and can reasonably distribute the reactive output of the LVSMs while compensating the voltage of the power grid when the voltage drop of the power grid occurs.

Description

technical field [0001] The invention belongs to the technical field of power grid demand side response, and in particular relates to a distributed collaborative control method for load virtual synchronous machines based on consistency. Background technique [0002] The large-scale access of renewable energy and controllable loads (electric vehicles) has improved the level of power electronics in the power grid, and has also led to a continuous decline in the overall damping and inertia levels of the power system, posing challenges to the stable and reliable operation of the system. In order to meet the challenges and fully tap the potential of the load side, some scholars have proposed to make the controllable load equivalent to the traditional synchronous motor in terms of operating mechanism and external characteristics by simulating the characteristics of the synchronous generator's body model, active power frequency regulation, and reactive power voltage regulation. Load...
