Description:
An advanced modulation technique-based harmonic control approach, known as hysteresis inverter control, in an inverter-connected renewable energy source (RES)-based islanded microgrid system is proposed in this paper. An LC low-pass filter is also used with the feedback control scheme in order to ascertain the control of harmonics in a desired manner. With a view to understanding both the fundamental and harmonic components of the output wave-shapes, fast fourier transform (FFT) analysis is carried out in this paper. MATLAB software is used to simulate the inverter performance within a microgrid system with the proposed feedback control. It has been found that system wave-shapes are sinusoidal and the total harmonic distortion (THD) is less than 0.5%, meaning the proposed method is effective.
