Simultaneous Operation of Personal Computers and Mathematical Assessment of Their Harmonic Impact on the Grid

In the smart grids environment, non-linear electronic devices are present to a great extent. Since these devices generate higher harmonics in the current spectrum and require high voltage quality in order to operate properly, the power quality issue becomes very important. This study deals with mathematical modelling of parameters of current and voltage harmonic distortion due to operation of PC cluster. The proposed models are developed using measurements and simulation results. Model parameters are derived in the least squares manner. The models are convenient for practical engineering application.
