Using general synchronous machine theory to integrate PLL controller dynamics into a static power electronic converter model Universiteit Antwerpen Universiteit Gent
Many distributed generators generate DC power, which needs to be inverted into AC active power to deliver power to the utility grid. In power electronic inverters the PLL algorithm synchronizes the injected current with the voltage. As a PLL is integrated in to a control loop, a multiplication is integrated in the controller, disabling classical analytical dynamic control theory. There are different types of inverters but in this paper it will ...
