Emerging Signal Processing Techniques for Power Quality Applications

The use of signal processing for power quality applications is not a new idea, as several researchers have used signal processing for more than a couple of decades. In the past few years, however, there has been a renewed interest in exploiting signal processing techniques for power quality measurements and analysis. The rationale for such enthusiasm is that signal processing techniques, indeed, provide meaningful and valuable information about voltage and current signals. As a result, a better understanding of time-varying, time-invariant, and transient behavior of power systems can be obtained.
