Abstract

This paper deals with transient stability augmentation using fuzzy coordinator in power systems with high penetration of wind turbines. The wind turbines are disconnected from the grid by their protection systems in severe fault situations. The disconnection may strike the power system by jeopardizing its transient stability due to reduction of active power. In this paper a fuzzy-based controller has been designed, that works as a coordinator between Automatic Voltage Regulator (AVR) and Power System Stabilizer (PSS). A salient feature of this work is that, the transient stability of power system is improved without any disconnection of wind turbines at the time of fault. Simulation results demonstrate that, the fuzzy coordinator ensures the transient stability of 11-bus power system with 20% penetration of wind turbines after outage of generator number 3.
