OPERATING A POWER CONVERTER

A method of operating a power converter (104) is provided. The power converter may be electrically coupled to a power grid (108) and outputs to the power grid converted electrical power. The power converter may be operable in a first operating mode in which the converter is operated based on a first reference (ε1*) generated by a virtual synchronous machine control scheme (201) and the power converter may be further operable in a second operating mode in which the converter is operated based on a second reference (i2*) that is not generated by the virtual synchronous machine control scheme. The method (500) may comprise switching the operation of the converter from the second operating mode into the first operating mode, wherein switching the operation may comprise obtaining (S10) one or more operating parameters while operating in the second operating mode and estimating (S15) from the one or more operating parameters a parameterization for the virtual synchronous machine control scheme. The switching the operation may further comprise parameterizing (S20) the virtual synchronous machine control scheme with the estimated parameterization and switching (S25) to the first operating mode by operating the virtual synchronous machine control scheme with the parametrization to generate the first reference (ε1*) and operating the converter based on the generated first reference.
