Integrating Wind Energy into Weak Power Grid Using Fuzzy Controlled TSC compensator

Abstract

Wind energy has been developed significantly over

last decade and has been noted as the most rapidly growing

technology and most cost-effective ways to generate electricity

from renewable sources. On the other hand, the voltage of wind

turbine driven generator is variable due to intermittent nature of

wind energy. Therefore, the integration of large wind scheme

can pose inherent security problems such as voltage fluctuations

and power quality.

Voltage control, power quality and reactive power

compensation in a distribution network with embedded wind

energy conversion system represent the main goal of this paper.

The dynamic simulation of the proposed voltage stabilization

TSC scheme is presented using fuzzy logic based controller.

The Wind Energy Scheme comprises three key parts. The wind

energy system, induction generator, TSC compensator with the

associated fuzzy logic controller and the distribution wind-grid

integrated AC system feeding the hybrid load.

The integrated wind-grid scheme with all subsystems has been

digitally simulated using the Matlab Simulink/Sim-Power

software environment. The fuzzy logic controlled TSC scheme

was fully validated to ensure voltage stabilization and efficient

wind energy utilization
