Peak to peak current minimization by differential evolution optimization

Popis výsledku v původním jazyce

This paper deals with differential evolution optimization of peak to peak current value, which consist of several harmonics with defined amplitudes. The actual amplitude of the current signal is computed as a sum of harmonics with different frequencies and depends on the harmonics amplitudes, phases and actual time. The paper presents the optimization algorithm of harmonic’s phases to reach the highest amplitude of all harmonics with the lowest absolute amplitude of resulted current (computed as a sum of all harmonics). The optimized current waveform is used as a reference signal for analogue hysteresis controller of single phase Hbridge inverter. The inverter works as a current source connected in parallel to auxiliary winding of Petersen coil. The H-bridge converter is used for injecting of selected current harmonics into power network grid. The measured converter voltage responses of injected current harmonics are used for grid resonant frequency identification. This information is used for tuning of Petersen coil.
