Abstract: The significant usage of power semi-conductor devices in modern single or multi-feeder distribution system is increasing a lot in present situation. The non-linear characterization of power distribution is highly responsible for degradation of power-quality standards. The usage of large-sized non-linear loads provokes the harmonic pollution, voltage interruptions, voltage sag/swell issues are the key problems faced by distribution systems. Over the various compensation methodologies, the highly validated universal device is Unified-Power Quality Compensator. The multi-feeder universal devices play a prominent role and provide the attractive performance with improved characteristics in multi-feeder distribution system. In this work, Multi-Feeder UPQC device is used to compensate all voltage and current related PQ issues in multi-feeder distribution systems and also furnishes load-sharing between adjacent feeders, reduce the power-shortages, maximizes the stable performance. The performance evaluation of proposed MF-UPQC is verified under various case studies with the help of Computer-Simulation tool, results are validated with improved PQ features.
