Internal Induced Voltage Modification for Current Limitation in Virtual Synchronous Machine
Energies, 2022 Virtual inertia control is a methodology to make inverter-based resources (IBR) behave like a synchronous machine. However, an IBR cannot fully emulate the response of synchronous machine because of its low-current capacity. When the inertial response of

Dynamic Modeling of the Electric Transportation Network [PDF]
, 2005 We introduce a model for the dynamic self-organization of the electric grid. The model is characterized by a conserved magnitude, energy, that can travel following the links of the network to satisfy nodes' load. The load fluctuates in time causing local

-Synthesis-Based Generalized Robust Framework for Grid-Following and Grid-Forming Inverters
IEEE Transactions on Power Electronics, 2023 Grid-following and grid-forming inverters are integral components of microgrids and for integration of renewable energy sources with the grid. For grid following inverters, which need to emulate controllable current sources, a significant challenge is to address the large uncertainty of the grid impedance.
