Effects Of Wind Farm On Low Voltage Networks

To meet up the desired demand of the electricity a lot of Wind farms are integrated with Power Networks. It has a lot of advantages over the traditional ways of generating electricity. Integration of the Wind farms to power system give rise to many problems like the predictability of wind plant output because instantaneous electrical generation and consumption must remain in balance to maintain grid stability. In almost every country of the world there is an ever-increasing wind energy penetration into power networks. In recent years the trend has been moved from installations with a few wind turbines to the planning of large wind farms with more than hundreds of MW of capacity. This increased and concentrated penetration makes the power network more dependent on, and vulnerable to, the wind energy productionDFIGs are mostly used in wind farms connected to the grid and they must meet the requirements provided by the power system. Effects of wind farms on power system is of great importance as it tells us the behavior of the power system that whether the system will be able to work in a proper manner after it is integrated with the wind farm. Several softwares are available to study the behavior of wind farm on powers system. This thesis will focus on the effects of wind farm on low voltage network.DFIG are mostly used during the installation of wind farms. In this thesis as we have to study the effects of wind farms on low voltage network so during the modeling process variable current source is used in place of the DFIG to make the work simple. A three phase current source is used to inject the current into the power system to control the active and reactive power and effects are studied in detail.
