An Adaptive Dynamic Reference Control for Power Converters in a Microgrid

This article proposes an adaptive dynamic reference (ADR) control for power converters in a microgrid. Conventionally, two separate controllers are required to the input current and dc bus voltage. The proposed ADR eliminates need additional controller by utilizing simple discrete-time model generate appropriate voltage regulation. technique is easy design guarantees convergence of its nominal even during nonidealities system, such as parameter uncertainties, sensor imperfections, unmodeled dynamics. A procedure parameters desired converter response also provided based on theoretical analysis. Unlike traditional linear controllers, independent converter’s operating point. Finally, performance validated experimentally using finite set predictive typical grid-connected application compared with both conventional controller.
