Topic:Wind Turbine Control for Improving Power Grid Flexibility 
Time: 9:30 a.m., Tuesday, Nov. 12th
Speaker: Prof. Yong Cheol Kang of Yonsei University
Venue: Room 201, Electric Engineering Building
Abstract:
Global penetrations of variable renewable energy (VRE) such as wind and solar have been rapidly increasing, thereby causing the severe frequency fluctuation. To secure the power grid flexibility in high penetrations of VRE, the frequency fluctuation should be maintained within a narrow band even when weather conditions are continuously varying. Otherwise, part of VRE should be curtailed to ensure the stable operation of a power grid. In this lecture, control technologies will be introduced that can mitigate the output power fluctuation of a wind turbine generator (WTG) by making use of the heavy rotating masses of a WTG as an energy storage system. These technologies help provide a promising solution to securing the flexibility in a power grid that has a high penetration level of VRE.
