Electric energy router with plug-and-play function

Abstract

The invention discloses an electric energy router with a plug-and-play function. The electric energy router comprises: a plug-and-play interface which comprises a power port and a communication port; a unit layer which adopts a droop control mode with a plug-and-play characteristic, wherein a rectifier cabinet and each direct-current transformer are main control units, and each main control unit carries out bus voltage regulation and control only by injecting alternating-current and direct-current bus power, output port voltage and other signals into the main control unit; and a system layer which adopts droop control based on active power and reactive power signals in the flexible interconnection switch, droop control based on active current and reactive current in the flexible interconnection switch, and droop control based on port output impedance in the flexible interconnection switch. According to the invention, active power and reactive power output by the power supply are respectively controlled, communication coordination among units is not needed, plug-and-play of the power supply and stable control of AC / DC bus voltage are realized, and power balance and frequency unification in the interregional interconnected micro-grid are ensured.

Description

technical field [0001] The invention relates to the technical field of power routers, in particular to a power router with a plug-and-play function. Background technique [0002] By adopting the concept of open peer-to-peer, the Internet of Information provides a variety of information services on the basis of innovative service models, making the Internet an infrastructure supporting current social development; The efficient transmission, sharing and utilization of energy provides a solid energy infrastructure for economic and social development. Therefore, the development model of the information Internet has a good reference for the development of the energy Internet. [0003] IP technology used to be an important driving force for the rapid development of the information Internet, but with the increasingly rich content of network services, the communication efficiency of the information Internet based on the IP mechanism is becoming more and more difficult to support peo...
