Title:
PHOTOVOLTAIC DIRECT-CURRENT DIRECT-FEED POWER GENERATION METHOD AND APPARATUS BASED ON CONTROLLABLE POWER SUPPLY
Document Type and Number:
WIPO Patent Application WO/2022/057363
Kind Code:
A1
Abstract:
Disclosed are a photovoltaic direct-current direct-feed power generation method and apparatus based on a controllable power supply. In the present invention, a photovoltaic cell is directly connected to a direct-current micro-grid, and the voltage of a direct-current bus is flexibly regulated and controlled by means of the controllable power supply in the direct-current micro-grid, such that the photovoltaic cell operates at the maximum power. Therefore, a direct-current interface converter required when the photovoltaic cell is connected to the direct-current bus is omitted, thereby reducing the cost and volume of a distributed photovoltaic power generation system.
