The penetration of growing microgrid systems within the ac distribution network is leading to several challenges to have a safe and reliable operation of the power system. For the utility system, it is mandatory to maintain the voltage and frequency within the prescribed limits at the local bus under diverse conditions of the renewable energy sources (RESs), loads, and grid. With these conditions,...
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...
This paper proposes a grid connected hybrid microgrid system with dual voltage source inverter (DVSI) using modified instantaneous symmetrical component theory (MICST) for power sharing among inverters. In this paper a reduced DC link voltage has been achieved, efficient, simple power management algorithm (PMA) is proposed and new method is introduced for DVSI control parameter extraction which reduces...
In this paper, application of battery and supercapacitor units based hybrid energy storage system (HESS) integrated to the grid interactive microgrid environment is presented. HESS is nowadays most widely used in the electric vehicles, energy reserves, renewable energy sources (RES)based applications. These energy storage systems can also be added to the existing power conditioning units to improve...
