This paper proposes a new direct power control (DPC) strategy for a doubly fed induction generator (DFIG)-based wind turbine system. The required rotor control voltage, which eliminates active and reactive power errors within each fixed time period, is directly calculated based on stator flux, rotor position, and active and reactive powers and their corresponding errors. No extra power or current...
This paper proposes a new direct power control (DPC) strategy for grid connected voltage source converters (VSC). Similar to an electrical machine, source and converter flux are defined as the integration of the source and converter voltage respectively. Based on the defined flux, the proposed DPC scheme directly calculates the required converter voltage to eliminate the active and reactive power...
