    • L1 Adaptive Speed Control of a Small Wind Energy Conversion System for Maximum Power Point Tracking 

      Zhao, Haoran; Wu, Qiuwei; Rasmussen, Claus Nygaard; Blanke, Mogens (Journal article; Peer reviewed, 2014)
      This paper presents the design of an L1 adaptive controller for maximum power point tracking (MPPT) of a small variable speed wind energy conversion system (WECS). The proposed controller generates the optimal torque command ...

    • Stability Boundaries for Offshore Wind Park Distributed Voltage Control 

      Gryning, Mikkel P. S.; Wu, Qiuwei; Kocewiak, Lukaz; Niemann, Hans Henrik; Andersen, Karsten H.P.; Blanke, Mogens (Journal article; Peer reviewed, 2016)
      In order to identify mechanisms causing slow reactive power oscillations observed in an existing offshore wind power plant, and be able to avoid similar events in the future, voltage control is studied in this paper for a ...
