Abstract/Description: The proliferation of semiconductor-based nonlinear devices in modern power systems has caused serious concern over the power quality problems. This dissertation proposes a control strategy to coordinate multiple active front-end converters so that harmonic currents as well as reactive power generated by the nonlinear load can be compensated. The objective of the proposed coordination strategy is to fully utilize the potential of the existing active front-end converters and minimize the space as well as the cost requirement for the power system where power quality improvement is needed. Under the proposed coordination strategy, the power quality distortion caused by a large nonlinear load is measured by a central controller and the corresponding power quality compensation task is distributed to multiple active front-end converters. The percentage of power quality compensation task assigned to an individual active converter is determined proportionally to its instantaneous power margin. The proposed coordination strategy can be a fairly flexible and economical solution for power quality improvement especially for the places where multiple active front-end converters are required and/or space-limited systems, such as manufacturing factories and/or shipboard or aircraft power systems. Both non-real-time and real-time simulation results show that the proposed coordination strategy has good performance and is both effective and promising.
