Abstract
A power converter can be controlled to generate a target output power based on a reactive power reference and an active power reference. The control process may include monitoring a time-varying power signal (e.g., a power grid voltage signal from a power grid), and filtering the time-varying power signal to derive a filtered sine component of the time-varying power signal and a filtered cosine component of the time-varying power signal. A sine coefficient and cosine coefficient each based on at least the reactive power reference and the active power reference can be determined, and applied to the filtered sine component and filtered cosine component of the time-varying power signal, respectively. A target current reference of the power converter can then be set to include a sum of the current reference sine component and the current reference cosine component.
