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. Classification of Custom Power Devices
It injects a synchronized voltage into the distribution feeder to maintain a constant load voltage during source disturbances. power quality enhancement using custom power de...
DSTATCOM, Dynamic Voltage Restorer (DVR), Unified Power Quality Conditioner (UPQC) are a new generation of power electronic controllers
It supplies or receives reactive power at the point of common coupling. Available with or without energy storage
DSTATCOM is a voltage source inverter (VSI) that maintains bus voltage at required levels.
Mitigating voltage sags and swells , which are the most frequent power quality issues.
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)
