Controller Design of an Active Front-End Converter Keeping in Consideration Grid Dynamic Interaction

This article presents a systematic control design procedure for an active front-end (AFE) converter connected to a power electronics embedded grid. A parametric model of the grid is first identified using the AFE itself to excite the system. This model is then integrated with the AFE one in order to obtain a global system representation. Subsequently, a globally optimized local controller is synth...
