Domestic energy local area network energy router and control strategy thereof

Abstract

The present invention relates to a domestic energy local area network energy router. The router comprises a controller, a solid state transformer and a plurality of interfaces. The interfaces are respectively connected with a major network and a distributed power supply, an energy storage device and a load in a domestic energy local area network, the controller regulates the voltage of the solid state transformer which is a dual-way structure and comprise an input-level high-voltage three-phase rectifier, an isolated DC / DC convertor and an output-level low-voltage three-phase inverter which are connected in order, the DC / DC convertor is a dual-way symmetrical structure and comprises a single-phase full-bridge inversion circuit, a high-frequency transformer and a one-way bridge total control rectifying circuit, the single-phase full-bridge inversion circuit converts the high-voltage direct current of the major network to high frequency square wave to realize secondary side voltage reduction through the high-frequency transformer and output to the low-voltage direct current bus through the single-phase full-bridge inversion circuit, and the low-voltage direct current bus is connected with the domestic energy local area network through the low-voltage three-phase inverter. Compared to the prior art, the domestic energy local area network energy router and the control strategy thereof optimize the energy configuration, enrich the electric energy flow and has good application prospect.

Description

technical field [0001] The invention relates to an energy router oriented to the energy Internet, in particular to an energy router and a control strategy for a household energy local area network. Background technique [0002] The depletion of fossil energy, the rapid deterioration of the global environment, the rapid changes in the world's climate, and the rapid development of power electronics and computer information technology have led to the vigorous development of renewable energy, such as wind energy, solar energy, and tidal energy. In order to maximize the utilization of renewable energy, distributed power generation technology based on power electronic converters, micro-grid technology, and smart grid technology have been deeply studied and widely used. Renewable energy will become the main energy source of human society in the future. . And because the fossil energy whose storage capacity continues to decrease can no longer meet the rapidly growing energy demand,...
