A Dynamic Coordination Control Architecture for Reactive Power Capability Enhancement of the DFIG-based Wind Power Generation

Project Code :TEPGPS161


The main objective of this project is to enhance the reactive power capability of wind power plants (WPPs) which deploy doubly-fed induction generator based wind turbines (DFIG-WTs).


In this project, dynamic coordination control strategy is used to enhance the reactive power capability of Wind Power Plants (WPPs) which deploy Doubly-Fed Induction Generator Based Wind Turbines (DFIG-WTs). The proposed control architecture seeks to maximize reactive power availability during grid faults without violating the stable and thermal operational limits of the generator. The proposed control topology calculates the maximum available reactive power that can be provided by the DFIG-based WPP under any disturbed operation of a power system. 

The reference value of the required reactive power compensation is there after calculated using an adaptive Proportional-Integral (PI) regulator which out performs the traditional PI controller. The computed reference value is directly applied to the outer control of the Rotor Side Converter (RSC) to regulate reactive power generation of the stator circuit. Furthermore, the P -V droop characteristics of the induction generator is employed to adjust the active power reference of the RSC converter to increase the reactive power capability during grid faults. 

Meanwhile, de-rating the active power generation of the DFIG-based WT is accompanied with modifying the pitch angle of the rotor blades to balance the mechanical and electromagnetic torques and to avoid any stresses excreted on the mechanical parts of the WT. If rotor current limits are reached and more reactive power support is still required, the responsible control loop of the Grid Side Converter (GSC) will be activated and augmented to enhance the overall reactive power capability of the DFIG-based WPP. Finally, the proposed control strategy is verified using Two area four machines test systems using MATLAB/SIMULINK software.
