Domestic power router

Abstract

The present invention discloses a domestic power router. The domestic power router comprises a direct current bus and an alternating current bus in the router; the direct current bus and the alternating current bus are connected through a bidirectional DC / AC converter; the router is provided with a plurality of interfaces; the direct current bus is connected with a DC / DC voltage boosting unit, a bidirectional DC / DC unit and a DC / DC voltage reduction unit; the DC / DC voltage boosting unit, the bidirectional DC / DC unit and the DC / DC voltage reduction unit are respectively connected with a photovoltaic array, an energy storage battery and a direct current load through the interfaces; the alternating current bus is directly connected with a large power grid, an important load and a heat storageload through the interfaces; each interface on the router is connected with one input-output power detection module; the interfaces are in communication connection with a system energy management controller through WiFi; and the system energy management controller is in signal connection with a microcontroller and a human-computer interaction interface in a wired mode. The domestic power router can achieve self generation and self use, networking by employing residual power and power grid regulation, and can convert residual electric energy to heat energy for storage through heating water orheating supply, and therefore, the storage battery capacity cost is reduced.

Description

technical field [0001] The invention relates to the technical field of routers, in particular to a household power router. Background technique [0002] As the Chinese government attaches great importance to the field of distributed photovoltaic power generation, the trend of miniaturization of the photovoltaic inverter industry is obvious. There are also some problems in the integration of a large number of household distributed renewable energy power generation devices into the grid. These new energy power generation methods are often geographically dispersed, intermittent, random, and uncontrollable. At the same time, a large number of distributed rooftop photovoltaic grid-connected in the low-voltage distribution network will lead to an increase in feeder voltage, excessive occupation of low-voltage transformer capacity, and occurrence of Issues such as reverse power flow and grid stability cannot be ignored. [0003] In order to meet the complexity and diversity requi...
