The Control of DFIG for MPPT and application of STATCOM for grid stability

Abstract

Themodeling, analysis, control and simulation of DFIG based WECS along with STATCOM implementation to the grid is presented in this paper. To maintain DC bus voltage the GVO control method is adopted in GSC for reactive power is provided. The efficient control of active and reactive power is provided through SVO scheme in RSC. The MPPT is achieved by keeping TSR to the optimum value.In this project implementation of STATCOM to grid system is shown in order to improve voltage stability during the grid disturbances. The three phase symmetrical fault is created in the distribution system and STATCOM which is connected to distribution system regulates the voltage drop and overcurrent to normal condition. The developed system is simulated for different wind speeds and allows power distribution system to be in-service during faults. The hardware prototype consists of voltage source converter and its controls are developed to verify the results.
