Abstract

See full text

Operating a renewable energy generator forming part of a renewable energy power plant. During a fault experienced by a power network: determining an active current set point to enable a reactive current supply boost at the point of connection between the plant and the network, the active current set point being based on a voltage level associated with the generator and on operational characteristics of the generator, plant, power network and/or connecting network; calculating a time period for the reactive current boost, the time period being the maximum time that the active current set point can be maintained for; and controlling the generator during the calculated time period to alter active current output to the determined active current set point, thereby providing the reactive current supply boost at the point of connection.
