Abstract
A method for providing primary frequency response for a renewable energy plant coupled to an electric power grid, the renewable energy plant having an intermittent energy source coupled thereto by an inverter, the method comprising: using a renewable energy plant control system, measuring frequency and determining a first difference signal between the measured frequency and a frequency reference; measuring power output from the renewable energy plant and determining a second difference signal between the measured power output and a power reference; generating an error signal from a sum of the first and second difference signals; generating a control signal by applying the error signal to a controller; limiting the control signal output from the controller to between predetermined minimum and maximum power limits for the inverter; while the control signal is limited by the predetermined minimum power limit for the inverter, disabling an integral function of the controller; and, applying the control signal to the inverter to control the power output from the intermittent energy source.
