Technical FAQs 4

Which energy storage devices and power converters are used in DVR?

Use of energy storage devices and bi-directional DC-DC converter helps to deliver quality power to consumers. Bi-directional topologies occupy lesser system space and deliver increased efficiency and better performance. In this paper, DVR topologies, different energy storage elements and power converters used in DVR are analyzed and reported.

How does a DVR save energy?

DVR saves energy through voltage injections that can affect the phase and wave-shape of the power being supplied. Devices used for DVR include static var devices, which are series compensation devices that use voltage source converters (VSC).

What is a DVR with energy storage topology?

DVR with energy storage topology include energy storage element, inverter and injection transformer as shown in Fig. 1. During sag, the inverter connected in series with the grid draws power from energy storage element and injects the missing voltage.

Which energy storage elements are used in DVR?

From the survey, it is observed that energy storage elements such as flywheel, battery storage, SEMS, super capacitor and ultracapacitors with suitable converter are used in DVR to mitigate the power quality issues. It has been summarized in Table 4.
