Abstract

Disclosed is a method for complementary power supplying of solar-energy photoelectric-conversion power generation and storage batteries. The method includes the following steps: 1. a solar-energy photoelectric-conversion assembly is connected with a storage-battery group and a charging and discharging controller and the solar-energy photoelectric-conversion assembly converts solar energy into electrical energy and charges the storage-battery group through the charging and discharging controller; 2. the charging and discharging controller detects the amount of electricity stored in each storage battery of the storage-battery group and controls a solar-energy cell to charges storage batteries which are low in electricity; 3. the charging and discharging controller extracts electrical energy from storage batteries which are high in electricity respectively in the storage-battery group and the electrical energy is converted into AC through an inverter and then power is supplied to a power grid or a load; 4. when the solar-energy photoelectric-conversion assembly is low in photoelectric-conversion quantity or does not perform photoelectric conversion, the charging and discharging controller extracts electrical energy from the storage batteries which are high in electricity from the storage-battery group and the electrical energy is converted into AC through the inverter and then the electrical energy is continued to be supplied to the power grid or the load so that stability of the power grid or the load is maintained.

Description

[0001] Technical field: method and device for solar photoelectric conversion power generation and storage battery complementary power supply. Background technique: [0002] Existing solar photoelectric conversion power generation can only perform photoelectric conversion and supply power to the grid or loads when there is light. When there is no light, solar photoelectric conversion power generation cannot be performed, resulting in instability of the power grid. Invention content: [0003] The purpose of the present invention is to combine solar photoelectric conversion power generation and storage battery to form a power supply system, store solar photoelectric conversion power generation in the storage battery, charge and discharge controller extracts electric energy from the storage battery according to a preset program to supply power to the grid or load, when When the solar photoelectric conversion module does not perform photoelectric conversion, the charge and dischar...
