Abstract
Connecting renewable sources in parallel to the grid with conventional sources is a challenging task. As the output of renewable sources is unstable, it needs to be stabilized using several passive and active elements to share power with the grid. The circuit system needs to be more efficient and stable with reduced ripple and harmonic content. In this paper, a three-phase transformer-less boost MLI topology is introduced with a PV array and PMSG wind farm renewable sources connected to the input. The MLI is connected to the grid through an LC passive filter to mitigate harmonic content. The proposed MLI has voltage-dividing capacitors to create voltage levels. The inverter comprises two stages, which include a voltage-level generator circuit and an inverting circuit. The voltage level generator circuit creates multilevel voltages only in a positive direction. The multilevel DC voltage is converted to AC by the inverting circuit, sharing power with the grid. The reference signal to the multilevel inverter pulse modulation technique controller is generated by modified fuzzy MPPT-based p-q control theory for efficient renewable power sharing to the grid. The boost converter at the input of the multilevel inverter ensures maximum power extraction controlled by the MPPT technique. The multilevel inverter ensures reduced harmonic AC voltage generation for sharing PV array power with low THD value to the grid.
