In order to provide support for the voltage, the energy-storage power source inverter needs an method to control the voltage source. Therefore, this paper has proposed the active damping control of a voltage source inverter (VSI) based on virtual compensation.
The buck nature of the VSI output voltage necessitates the use of a boost converter between the energy storage and the inverter, which adds more switches, controls, and complexity. By using a multilevel inverter in place of VSI partly or entirely, the need for filters can be eliminated, resulting in fewer switching losses.
The inverter is controlled by the pulses generated by the PWM pulse generator. The magnitude and phase angle of the reference voltage are generated using a correction approach and are fed into the multilayer inverter. This data are derived using phase-locked loops (PLLs). Rotating DQ reference frame controller.
The error signal and change in error signal drive the PI controller, which analyses the input and generates controller output. The PWM receives the controller output as a reference voltage. The inverter is controlled by the pulses generated by the PWM pulse generator.
TCHB inverter [ 259] was used to mitigate the voltage sag using two voltage compensation schemes, in-phase and presag compensation. In [ 260 ], the authors proposed an S4L inverter-based DVR with a single DC power source and reduced switch count; thus, it is more cost-effective.
The depth of the sag and duration of the sag determines the storage capacity. If there is a long-term sag, the energy storage capacity declines and the DVR’s compensating property gets reduced.
Studies reviewing the DVR include many areas, but specifically, power quality issues, energy-storage topology, absence of energy, and controlled strategies are covered in this paper. DVR configurations based on power converters and control units at different stages are described in detail based on the latest literature.
