Active filtering, load balancing, and voltage regulation (sag/swell). Major Compensating Devices 1. Dynamic Voltage Restorer (DVR) Mitigating voltage sags and swells , which are

Available with or without energy storage; storage-based models use batteries or capacitors to provide the necessary active power for compensation. 2. Distribution Static Compensator (DSTATCOM) Mitigating voltage sags and swells

DSTATCOM is a voltage source inverter (VSI) that maintains bus voltage at required levels.

Static Transfer Switch (STS), Static Current Limiter (SCL), Static Circuit Breaker Fast switching for fault isolation and rapid load transfer.
