چکیده
The grid voltage modulated direct power control (GVM-DPC) is a novel regulation method for grid-connected source inverters (VSI). However, interactions between real and reactive powers still exist in GVM-DPC under unbalanced condition, which may deteriorate its transient performance. This article proposes decoupling GVM-DPC-based VSI systems based on the dynamic feedforward compensation strategy, can reduce coupling magnitudes of stages. First, mechanism positive negative sequence condition analyzed. Then, (PCM) are derived according to relationships among components power, point common (PCC) voltages. Next, PCM compensated into better Furthermore, stability analysis proposed system studied impedance model, comparison with traditional virtual conducted show superiority method. Finally, simulations, hardware-in-loop test experiment validate effectiveness

Low Voltage Ride Through Enhancement Based on Improved Direct Power Control of DFIG under Unbalanced and Harmonically Distorted Grid Voltage
In the conventional structure of the wind turbines along with the doubly-fed induction generator (DFIG), the stator is directly connected to the power grid. Therefore, voltage changes in the grid result in severe transient conditions in the stator and rotor. In cases where the changes are severe, the generator will be disconnected from the grid and consequently the grid stability will be attenu...
متن کاملA model-based PDPC method for control of BDFRG under unbalanced grid voltage condition using power compensation strategy
Brushless doubly fed reluctance generator (BDFRG) has been recently suggested as a wind generator. Different control methods are presented in literature for the BDFRG, but there is a gap on control under unbalanced grid voltage condition (UGVC). This paper presents a predictive direct power control (PDPC) method for the BDFRG under UGVC. The proposed PDPC method is based on power compensation s...
