Impacts of Nonlinear Loads on the Power Quality of Solar Microgrids and Proposed Mitigation Strategies

Energy Science &Engineering, Volume 13, Issue 4, Page 1960-1982, April 2025.
Nonlinear loads in solar microgrids introduce power quality issues such as harmonics, voltage distortions, and reduced system efficiency. These disturbances negatively impact the stability and performance of microgrid components, leading to increased losses and potential equipment damage.

PZS‐Net: Incorporating of Frame Sequence and Multi‐Scale Priors for Prostate Zonal Segmentation in Transrectal Ultrasound

Advanced Intelligent Systems, Volume 7, Issue 1, January 2025.
A deep‐learning‐based segmentation method that aimed to segment prostate zones in transrectal ultrasound videos shows results similar to the labels annotated by expert urologists in a prospectively acquired test database. The method is demonstrated to significantly improve prostate zonal segmentation compared with popular segmentation methods.

Constrained FCS‐MPC‐Based Current Controller for Voltage Source Converters: Application to Shunt Active Power Filters

IET Electric Power Applications, Volume 19, Issue 1, January/December 2025.
In this paper, a constrained FCS‐MPC based current controller is introduced for controlling shunt active power filters. In the proposed current controller, the objective function is same as used in the conventional FCS‐MPC and a switching frequency constraint is considered to reduce the average switching frequency. The results obtained from FPGA in the
