Trilateral control for LCL filter‐based system with single grid current sensor in weak grid

IET Energy Systems Integration, 2023
A trilateral control for LCL filter‐based system is introduced by the authors with a single grid current sensor in weak grid conditions. The LCL filter increases the complexity when the uncertain nature of the grid comes into the picture.

Power Quality Assessment in Railway Traction Supply Systems [PDF]

IEEE Transactions on Instrumentation and Measurement, 2020
The assessment of the power quality (PQ) could be a valuable tool to foster the efficiency of the railway systems. PQ is a well-addressed topic in conventional ac 50/60 Hz power systems, and many procedures, algorithms and measurement systems were presented in the international standards and widely discussed in the scientific literature.
