Wind energy penetration into distributed generation and its static and dynamic features

Abstract

Wind Energy Conversion Systems (WECS) are penetrating into Microgrids as they fit well to the concept of Distributed Generation. The variable speed Doubly Fed Induction Generators (DFIG) are most frequently used. Changing the speed (DFIG) according to the aerodynamic law, maximum wind power can be harvested. The paper investigates the way of speed change by rotor voltage in steady-state and in transient. Steady state characteristics and simulation results for dynamic behavior are included.
