Wind Oscillatory and Gusting Torque Effect on a Power System

Abstract

The dynamics of a wind turbine driven induction machine and the power system to which it is connected in a dispersed mode are described. The sources of disturbances are identified as ramp and low frequency cyclic turbine torque variations as a consequence of sharp fronted wind gusts and tower shadow, rotor unbalance, etc. Studies have been performed for two levels of wind energy penetration in a single area power system and in a multiarea interconnected power system. Results show that substantial wind energy penetration levels can be handled in a multiarea power system.
