Power Quality Issues in Renewable Energy Systems

power quality issues

The term power quality is a measure of the purity of the AC power, including the presence of unwanted harmonics and noise on the power line and the frequency. A harmonic is a frequency that is a whole-number multiple of another basic frequency. Harmonics on the power line are multiples of the power line …
