Abstract

Methods, systems, and computer readable media are disclosed for maintaining photovoltaic power plant reactive power capability, e.g., through the manipulation of direct current (DC) voltage. In some examples, A control system includes a monitor input for receiving a monitor signal indicative of an input voltage of an inverter system and a control output for outputting a control signal to a voltage-clipping device of a solar panel system supplying a solar output voltage to the inverter system. The control system includes a control circuit configured to perform operations comprising: determining, using the monitor signal, that the input voltage of the inverter system exceeds a threshold voltage; and in response to determining that the input voltage of the inverter system exceeds the threshold voltage, causing, using the control signal, the voltage-clipping device to reduce the solar output voltage by shorting out one or more photovoltaic solar cells of the solar panel system.
