Document Type and Number:
WIPO Patent Application WO/2022/166537
Kind Code:
A1
Abstract:
Provided are a photovoltaic system and a power supply current control method therefor. The photovoltaic system comprises a direct-current bus, and at least two power supply units, which are connected to the direct-current bus in parallel. The power supply current control method for the photovoltaic system comprises: acquiring the current power supply state parameter of each of at least two power supply units; determining a reference power supply current value of each power supply unit according to the current power supply state parameter of each power supply unit; and adjusting the current power supply power of each power supply unit according to the reference power supply current value of each power supply unit. By means of the present application, rational load allocation between power supply units can be ensured, and the present application has strong applicability.
