Household energy router

Abstract

A household energy router includes a grid-connected module, a photovoltaic power generation module, a storage battery energy storage module, a diesel power generation module, and a household electrical AC load module. Respective modules are connected to a DC bus through a routing port. The routing port includes a power electronic converter that can interconnect electrical energy with other energysources (such as lighting illumination, oil and the like) and that can achieve rectification, inversion, isolation, and voltage boosting and reduction. The household energy router is oriented to household AC loads and achieves energy management and information interaction by using a grid-connected port as a master control via controllers and communication circuits of respective ports. The energy router has multiple ports, can get access to multiple power generation apparatuses, energy storage apparatuses, and household electric loads simultaneously, can flexibly control the magnitude and the flow direction of different energy according to the peaks and valleys of an AC grid and actual load requirements in a grid-connected state, can achieve energy flow between different apparatuses in an island state, and can achieve comprehensive energy use.

Description

technical field [0001] The invention relates to the field of power electronic converters and information technology, in particular to an energy router for household loads. Background technique [0002] In recent years, in order to alleviate the energy crisis and environmental pollution, distributed renewable energy has been widely used in the power grid, but these renewable energy are often geographically dispersed and intermittent. This requires adding a large number of energy storage devices to the grid to buffer these fluctuating energy. On the other hand, the traditional single centralized power generation network is gradually installed into a centralized and distributed power generation mode, and the one-way flow of electric energy has also begun to change into a multi-directional flow. [0003] In order to meet the complexity and diversity requirements of the future power grid for power control, some scholars have proposed that the future power grid will use microgrid...

Problems solved by technology

However, the system is an off-grid system, which can only supply power to local loads and cannot be connected to the grid.

CN102780267A discloses a power router that uses switch arrays to form energy channels. The control is complicated. If a single switch fails, it will affect the overall situation
