Virtual Impedance Impact on Inverter Control Topologies [PDF]

2018 7th International Conference on Renewable Energy Research and Applications (ICRERA), 2018
The different nature of the energy resources requires high reliable power inverters to supply regulated power to the end customer and to ease its integration within the microgrid. In this paper, modeling, design and control of inverters are presented for two different topologies.
