Impact of Wind Integration on National Transmission Network

Abstract

Due to the scarcity of fossil fuels and their increasing prices, adoption of renewable resources has become inevitable. Wind energy is being recognized as a potential renewable source of bulk power generation in Pakistan, just as across the world. The wind corridor located from Hyderabad to Keti Bandar has an immense potential for power generation, with two windfarms already in operation and many more planned. A stability analysis of installed and potential Wind Turbines Generators (WTG) type needs to be performed, to analyse the impact of power injection from wind turbines on the voltage level and grid stability of the power network. This analysis can further help to identify appropriate integration location and suitable wind turbine generator for AC network support. This paper presents the analysis of network strength at the point of wind the turbine generator’s connection and a comparison of wind turbine generators to support the AC network, which will be useful for identification of suitable type of WTG for reliable operation of integrated system.
