Some technology with several standards has been developed to address the problems like voltage dip, sag, and swelled. These advanced techniques mitigate undesirable quality issues. Precise monitoring is done by utilising proper power electronic devices. So much research work is going on to give more focus to the microgrid...

Using an Active power filter, this work presents a novel way for balancing source side current harmonics in power systems produced by the presence of nonlinear characteristic loads (APF). Because of the advanced, nonlinear, and non-stationary nature of systems that contain a large number of diverse constraints, optimising capacity...

This work presents the application of dynamic voltage restorers (DVR) with three level inverter on power distribution systems for mitigation of voltage sags/swells at critical loads. DVR is one of the compensating types of custom power devices. An adequate modelling and simulation of DVR, including controls in MATLAB, show...

A new efficient control method for a unified power quality conditioner is created in this work, which can eliminate voltage changes such as sag and swell situations in distribution systems, as well as current and voltage harmonic isolation. The proposed control approach is utilised to model and simulate the...
