Modeling and Analysis of Wind Farms Connected to the Egyptian Power System
Journal Title: IOSR Journals (IOSR Journal of Electrical and Electronics Engineering) - Year 2018, Vol 13, Issue 5
Abstract
It has been observed in the past few years that wind, as a source of energy, has been growing worldwide. Its penetration in the power system has increased dramatically. At the present time, wind turbines are seen to be connected to both transmission and distribution systems. These connected turbines incorporate different technologies. The most dominating technology is the variable speed technology. Doubly Fed Induction Generator (DFIG), one of the generators utilizing this technology is the most used generator type today. This is because it has many advantages that makes it superior over other types of generators. Among these are, the presence of power electronic equipment which facilitates the process of control. In this paper, the various DFIG models are described.A case study was then conducted on an area of the Egyptian grid. This area has two wind farms; one wind farm utilizing the fixed speed induction generator concept whereas the other wind farm utilizing the doubly fed induction generator concept. A fault was simulated at one of the two lines connecting the two wind farms to the external grid. The wind farm interaction with the power system was evaluated and it was shown that the doubly fed induction generator wind farm had the ability to support the fixed speed induction generator wind farm during the fault and also support the process of voltage reestablishment.
