Abstract
A voltage regulation method for a multi-converter parallel connection system is provided. The multi-converter parallel connection system includes N converters. Alternating-current sides of the N converters are connected to an alternating-current bus. N is an integer greater than or equal to 2. M converters among the N converters are switched from a current-source operation mode to a voltage-source operation mode to form an alternating-current bus voltage, when the N converters are disconnected from a power grid or the power grid fails. M is an integer less than or equal to N. Remaining N-M converters among the N converters are switched from the current-source operation mode to the voltage-source operation mode after the alternating-current bus voltage is formed.
