TAILIEUCHUNG - Effect of wind power on power system stability

This paper focuses on the wind turbine technology influences on the power system voltage stability and on the power system quality. Because of lacking controls on active and reactive power, this wind turbine technology is considered the poorest power quality when harmonics problems are not concerned. | ISSN:2249-5789 Meenakshi Mataray ,, International Journal of Computer Science & Communication Networks,Vol 2(4), 506-511 Effect of Wind Power on Power System Stability Meenakshi Mataray ,AP Department of Electrical Engineering Inderprastha Engineering college (IPEC) Ghaziabad Sahibabad India Email: Abstract: This paper focuses on the wind turbine technology influences on the power system voltage stability and on the power system quality. Because of lacking controls on active and reactive power, this wind turbine technology is considered the poorest power quality when harmonics problems are not concerned. It includes analysis of the wind power influences on the voltage stability, power system stability and power quality characteristics.

INTRODUCTION In the present power scenario, the demand for electrical power is increasing and conventional resources are depleting fast. Recent studies indicate that there are substantial improvements in the utilization of renewable energy sources especially in the developing countries. This is because of the recent technological developments and also due to environmental and social considerations. Wind energy has experienced remarkable growth over the last decade due to renewed public support and maturing turbine technologies. Many wind turbines use a squirrel cage induction generator to produce electricity. These generators allow small variations in rotor speed thus reducing torque shocks caused by wind gusts. However they absorb large amounts of reactive power and cause severe voltage stability problems on the grid. Traditional shunt compensation using fixed capacitors, due to varying load conditions on the grid and sudden wind gust, sometimes leads to large voltage fluctuations in the grid as the reactive power consumed by the WEG varies widely. .So, FACTS .
