The following graph was obtained using the MATLAB Doubly-Fed Induction Generator (DFIG) wind turbine model.

I'm confused about why spikes occur at the points A to B and C to D.

If you have any reference books related to the graph please let me know.

The system is controlled to follow this so-called "ABCD" curve, it is the Maximum Power Point Tracking (MPPT) curve for the Doubly-Fed Induction Generator (DFIG).

To get started, read the paragraphs about "ABCD" in the following:

  • Xinshou Tian, Weisheng Wang, Yongning Chi, Yan Li, Chao Liu, "Virtual inertia optimisation control of DFIG and assessment of equivalent inertia time constant of power grid", Selected Papers from the 6th IET Renewable Power Generation Conference (RPG 2017), online
  • Moulay Tahar Lamchich, Nora Lachguer, "Matlab Simulink as Simulation Tool for Wind Generation Systems Based on Doubly Fed Induction Machines", in MATLAB: A Fundamental Tool for Scientific Computing and Engineering Applications - Volume 2, ed Vasilios Katsikis, 2012. online.
