Inertial Response and Power Oscillation Damping Using Fuzzy Controller with Pmsg-Based Wind Turbines

Abstract

- According to this paper we are analysis an improved active power control method for variable speed wind turbine which is used to enhance the inertial response with the damping capability during the transient system. Here we are implementing the fuzzy logic controller for the better performance comparing to the other controller.  According to the optimized power point tracking (OPPT) controller we can shift the turbine operating point to the maximum power point tracking (MPPT) curve which control the virtual inertia control (VIC) curves according to the frequency deviation which is used to proposed to release the “hidden” kinetic energy and provide dynamic frequency support to the grid. Fuzzy controller is the most suitable for the human decision-making mechanism, providing the operation of an electronic system with decisions of experts. According to the effects of the VIC on power oscillation damping capability which is theoretically evaluated. We are comparing the conventional supplementary derivative regulator  which  is depend upon the inertia control, during transient events it not only provide the fast inertial response but also increase the system damping capability. By using the simulation result we can analysis the inertial response and power oscillation damping function can be obtained in a single controller by the proposed control system.
