Abstract
A computer-implemented method for controlling provision of reactive power services by inverter-connected devices in an electric power network is provided, the inverter providing a maximum allowable apparent power S max This method is based on the inequality S where P is the active power and Q is the reactive power. max 2 ≧P 2 +Q 2 by approximating the circle defined by said inequality as an n-sided polygon. The method may also be used to control the system frequency of an electric power network. Also provided is a reactive power device for a power supply network, the device having an inverter, the inverter deriving a maximum allowable apparent power S max and operatively connected to a computing arrangement configured to execute a mixed integer linear programming model that implements the method.
