Abstract: The field of power systems includes a switching control method for a converter apparatus in a power supply system and the apparatus. This solution may be applied to a power conversion system in scenarios such as a new energy microgrid or an electrochemical energy storage station. In the method, a voltage of the converter apparatus at a control switching moment is stored, the voltage is used as an initial value after switching is performed, and the voltage is transited to a rated voltage in a first time period.

Abstract: A power supply system includes N distributed generations and at least one detection control unit. The N distributed generations are connected in parallel or in series and then connected to a power grid, and N is an integer greater than 1. The detection control unit is configured to: when detecting that oscillation of the power supply system exceeds a preset threshold range, obtain a power compensation control proportion of each distributed generation based on impedance from each distributed generation to a point of common coupling of the power supply system. The power compensation control proportion is a proportion of power output by each distributed generation to total power output by the power supply system. The detection control unit is further configured to control a power output proportion of each distributed generation based on the power compensation control proportion.
