An EV (Electric Vehicle) could play a prominent role in transport sector in terms of cost benefit and environment issues. A battery charger must have high efficiency and dependability with a unity power factor current drawn at its input AC mains since it is directly going to affect the charging time and life of the battery used in EV. Conventional AC-DC converter uses a diode bridge rectifier at the...
In this paper, a renewable energy based wind-PV microgrid is investigated for seamless transfer between the grid connected and isolated modes according to the grid availability. The VSC (Voltage Source Converter) based voltage and current controls are used to provide smoothness in both the operations. A battery bank is connected at the DC bus of VSC for load leveling during low power generations or...
This paper proposes an islanded hybrid microgrid system with dual voltage source inverter (DVSI) using instantaneous symmetrical component theory (ISCT) for reference current generation and power management. In this work a reduced DC link voltage has been achieved and efficient, simple power management algorithm (PMA) which takes account of load shedding and off-MPPT operation is proposed under islanded...
