Influence of the wind farm integration on load flow and voltage in electrical power system

• The behavior of a wind farm integrated into the electrical power system.
• The impact of the wind turbine on the voltage, load flow and the frequency.
• The capability of the unified power flow controller UPFC to solve the power system complications.

The present paper describes the behavior of a wind farm integrated into the electrical power system and the effect of this energy on the different grid parameters such as the voltage, the load flow and the frequency. A proposed solution for these kind of complications whilst inserting the wind farm is discussed also.Initially in this work a simple five nodes grid are studied, this network containing two power plants, feeding a load over a distribution system, then one of these power plants is replaced by a wind farm. Finally a UPFC is inserted at the transmission system trying to improve the electrical system profile.The main aim of this study is to get an idea about the impact of the wind turbine on the voltage, load flow and the frequency and to find the solution. Furthermore, a comparison between the simulations results is carried out at the end of this paper.
