Hybrid solar inverter based on a standard power electronic cell for microgrids applications

The aim of this work is the development of an 80 kW solar photovoltaic generation system based on a standard power electronics cell for microgrid applications. The proposed system is capable to provide security of supply by delivering uninterrupted power to critical loads in standalone operation and transition seamlessly between stand alone and grid connected mode. To mitigate the effect of variability of the generation and load demand a state of the art 20 kWh lithium-ion battery is used to balance the power flow in the system. This paper presents Description of the hardware, proposed controls strategies and simulation models of the system.
