Abstract
A harmonic suppression method, system and device using active power filtering based on a Virtual Oscillator Control (VOC) inverter are provided. The method includes the following steps: firstly, the basic structure and control of VOC and its parameter design are given; then the parameters of VOC are designed; then the active filtering harmonic suppression strategy based on VOC is proposed; finally, the suppression strategy is applied in the grid-connected inverter system and its effectiveness is verified by simulation.
