A Fault Level-Based System to Control Voltage and Enhance Power Factor Through an On-Load Tap Changer and Distributed Generators

The on-load tap changer is critical for voltage regulation, however, its regulation philosophy suitable one-directional power flow systems. Since distributed generators introduce bidirectional flow, the conventional operation of will be highly impacted, resulting in high magnitudes that exceed acceptable limits, frequent magnitude fluctuations, and increase overall reactive supply when start absorbing/injecting power. Therefore, an adaptive control system proposed on this paper alters existing also coordinate capabilities with those optimal reduction flows through system, enhancing factor thereof. change centralized, single-variable busbar monitoring technique a decentralized, multi-variable strategy controls based average entire distribution network. calculate setpoints network voltage, deviation from nominal points connection total transformer. was tested 22kV modelled MATLAB SIMULINK results attained revealed multi-stage can successfully simultaneously improve factor.
