Problems solved by technology

[0003] (1) The traditional way of connecting loads to the power system is only the transmission of energy without the exchange of information, resulting in the lack of necessary information interaction between connected equipment and systems
[0004] (2) The connection and withdrawal of power equipment fails to achieve soft switching, and the voltage and current impact at the moment of connection has an impact on system stability
[0005] (3) The power equipment connection process requires pre-configuration of the energy router, and the cost of operation and maintenance is high

Abstract

The invention discloses a power energy router interface plug-and-play realization method, which relates to the field of use of power energy routers and aims at ensuring reliable connection and stableenergy exchange of a power device and reducing the impacts of hard connection of the power device on an energy router system. The power device is connected to a 360V DC bus through a power converter,and a signal coupler is connected across two ends of the power converter; the information of the power device is collected, and a load characteristic library of the power device is established; and the currently connected power device type is identified and the current operation state information of the power device is acquired; a power device model is extracted from the load characteristic library, whether the power device is in a fault state is judged, and the operation state information of the power device at the next moment is predicted; in a non fault state, the power converter port parameters are adjusted to enable the power converter and the connected power device to realize no-error connection; and in a fault state, teh power converter is controlled to stop energy transmission.

Description

technical field [0001] The invention belongs to the communication field, and in particular relates to the use of a power energy router. Background technique [0002] With the development of social economy and the change of energy structure, the application of renewable energy, energy storage, electric vehicles, etc. in people's life is growing rapidly. In order to adapt to the development of the power system, people put forward the concept of power energy router (hereinafter referred to as energy router) to solve the problems caused by the access of renewable energy and new loads to the power system. The energy router is an open and integrated system that needs to support the access and exit of various types of power equipment. Therefore, the energy router needs to provide flexible and diverse interfaces for various types of power equipment. The current energy router technology has the following problems: [0003] (1) The traditional way of connecting loads to the power sy...
