The DVR is a device that acts as a controlled voltage source.
It injects a synchronized voltage into the distribution feeder to maintain a constant load voltage during source disturbances.

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)
DSTATCOM, Dynamic Voltage Restorer (DVR), Unified Power Quality Conditioner (UPQC) The DVR is a device that acts as a controlled voltage source
Power factor correction, load balancing, and mitigating current-related harmonics. 3. Unified Power Quality Conditioner (UPQC)
The UPQC is considered the most powerful CPD as it combines both converters via a common DC link. Available with or without energy storage
are a new generation of power electronic controllers designed for medium to low voltage levels (typically 1 KV through 32 KV) to ensure high-quality power delivery. Unlike Flexible AC Transmission Systems (FACTS) which focus on high-voltage transmission, CPDs are specifically applied at the distribution level to protect sensitive consumer equipment.
