Novel household electric energy router system and control method

Abstract

The invention discloses a novel household electric energy router system and a control method. The system comprises a photovoltaic battery pack, a photovoltaic module, a charging pile module, an electric vehicle storage battery and a grid-connected converter module,the four modules are connected in parallel, and the photovoltaic battery pack is used for obtaining light energy and converting the light energy into output electric energy. The control method comprises the following steps that: in a normal mode, the four modules are controlled to be in a full operation state; and in an emergency mode, the grid-connected converter module converts electric energy stored in the storage battery of an electric vehicle into alternating-current electric energy from direct-current electric energy so as to supply power to an emergency load. An existing electric energy router only provides electric energy for an electric vehicle by utilizing photovoltaic power and does not have an emergency standby function, that is, when a power grid breaks down, the existing electric energy router cannot solve the problem of household emergency load power supply. With the novel household electric energy router system and the control method of the invention adopted, the above problem can be solved,the power utilization under the emergency condition is ensured, and the electric energy cost is saved.

Description

technical field [0001] The present application relates to the technical field of power electronic equipment, and in particular to a novel household power router system and control method. Background technique [0002] With the gradual depletion of fossil energy such as coal and oil, new energy will become the main force in the future energy utilization system. Solar energy is inexhaustible, inexhaustible, and environmentally friendly and non-polluting. In addition, my country's rural areas have a vast territory, a large population, and a single energy structure, which is conducive to the large-scale development of household photovoltaics, which can reduce long-distance The power loss generated by power transmission can also promote the power market reform to a certain extent. However, single photovoltaic power generation has the potential disadvantages of unstable output power and great weather influence. Therefore, the combination of photovoltaic power generation and energy...
