Assistant Research Scientist Dr. Wesam Rohouma and Postdoctoral Researcher Dr. Morcos Metry presented their research on improving the reliability of the Capacitorless D-STATCOM in the distribution networks on November 10, 2020. The workshop, which was held virtually, was originally scheduled to be in-person in Aalborg, DENMARK.
This paper presents a method based on Model Predictive Control (MPC) to reduce switching losses in the converter by controlling the error margin size (aka penalizing fidelity) while maintaining acceptable operation within IEEE harmonics standards. This work results show a reduction in switching frequency by over 30%, which results in reducing switching losses and improving the reliability of the system.
