Embodiment Construction

[0030] figure 1 Schematic diagram of the structure of the solar power storage system. In one embodiment, the system includes a solar panel 10 , a first capacitor 20 , a DC / DC converter 30 , a logic controller 40 , and a second capacitor 50 .

[0031] The solar panel 10 is a light energy and electric energy conversion component, which can be connected in parallel or in series according to requirements.

[0032] One end of the first capacitor 20 is electrically connected to the solar panel 10 and the DC / DC converter 30 , and the other end is grounded. The first capacitor 20 is a low-resistance, high-capacity instantaneous power supercapacitor, which can be used as a temporary storage of electric energy. The first capacitor 10 can be a metal oxide electrode supercapacitor, a carbon supercapacitor, a polymer supercapacitor, a hybrid supercapacitor, an aluminum electrolytic capacitor or similar high-capacity capacitors. In a steady state of dynamic balance, the first capacitor 2...

Abstract

The invention relates to a solar energy power generation and storage system and a method. The solar energy power generation and storage system comprises a solar panel, a first capacitor, a direct-current/direct-current converter, a controller and a second capacitor, wherein the first capacitor is used for receiving the output electric energy of the solar panel and outputting the electric energy to the direct-current/direct-current converter, the direct-current/direct-current converter is used for adjusting the output voltage of the solar panel and the first capacitor, the controller is used for adjusting the work cycle value of the direct-current/direct-current converter, and the second capacitor is connected with the direct-current/direct-current converter and the controller and used for storing the electric energy generated by the solar panel. The solar energy power generation and storage method comprises the steps as follows: converting the solar energy into electric energy, providing the first capacitor for storing the electric energy converted from the solar energy temporarily, adjusting the voltage of two ends of the first capacitor by the direct-current/direct-current converter, providing the controller for adjusting the work cycle of the direct-current/direct-current converter, and providing the second capacitor for storing the electric power output by the direct-current/direct-current converter.

Description

【Technical field】 [0001] The invention relates to a solar power generation system, in particular to a solar power generation energy storage system and method. 【Background technique】 [0002] Solar energy is the most common energy source that can be miniaturized. However, the voltage and current of solar panels are not linear, which is a non-ideal renewable energy source. The power generated varies significantly with the sunshine environment, angle and temperature. In order to obtain the maximum power efficiency, the maximum power tracking method is used to realize the real-time detection of the output power of the solar panel. The current maximum power tracking is to check the voltage and current of the solar system, and compare the power through the product or processing calculation to confirm the maximum power adjustment. Direction, the process is too complex and time-consuming, and the sun's illuminance or temperature changes rapidly, making it difficult for the system to...
