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.

Microgrid operation improvement by adaptive virtual impedance [PDF]
IET Renewable Power Generation, 2018 Microgrids (MGs) are regarded as the best solution for optimal integration of the renewable energy sources into power systems. However, novel control strategies should be developed because of the distinct inherent feature of MG components in comparison to conventional power systems.

Virtual Training Laboratory for Primary Impedance Metrology
IEEE Transactions on Instrumentation and Measurement, 2023 This article presents the concept and some aspects of the physical implementation of a virtual training laboratory (VTL) in the field of primary impedance metrology. The creation of a VTL provides a novel method of disseminating metrological knowledge and expertise in a practical way and at a low cost. It will expose new users to the live experience of

Adaptive Impedance-Conditioned Phase-Locked Loop for the VSC Converter Connected to Weak Grid
Energies, 2021 In this paper, an adaptive version of the impedance-conditioned phase-locked loop (IC-PLL), namely the adaptive IC-PLL (AIC-PLL), is proposed. The IC-PLL has recently been proposed to address the issue of synchronisation with a weak AC grid by ...
