Advanced Control of FACTS Devices for Improving Power Quality Regarding to Wind Farms

In recent years, there has been a worldwide development in the utilization of wind farms. Because of enlarging wind generation, growing non-liner loads and competitive electricity markets the operation mechanism of power systems are facing some problems like voltage regulation, damping of power oscillation, etc. in shunt FACTS devices STATCOM and SVC have been identified as a good device and perfect compensators to solve these troubles. So control strategies for STATCOM are sequentially changing. The proposed paper is shown that the use of advanced control methods, such as the standard robust control method, in the control system of FACTS could improve their performance.
