Wind-PV Based Microgrid Assisted EV Charging Infrastructure Control

This work entails a multilevel reorientated generalized integrator (MRGI) based control strategy for microgrid assisted electric vehicle charging infrastructure. The microgrid consists of permanent magnet synchronous generator (PMSG) based wind energy conversion system and solar photovoltaic (PV) array. The converter is synchronized in a three phase two stage configuration through the PV side. The MRGI satisfies the EV charging infrastructure requirements as well as its demand dynamics and transfers the perennial power to the grid side. Power is taken from the photovoltaic module and wind side and transferred to the grid side while fulfilling the EV charging demand. The filter works towards extracting the fundamental component from the local nonlinear currents and distorted voltages. The fundamental positive sequence component is then utilized directly to synchronize the converter. maximum power point tracking (MPPT) algorithms are used for wind and PV array to extract peak power. Even during extremely polluted grid conditions, the system works according to the required grid codes. The results are obtained on developed hardware prototype to validate design and control.
