IEEE transactions on industrial electronics (1982. Print), 2023 As the capacity of renewable energy generation increases, grid-forming (GFM) inverters are deemed as promising solutions for low inertia power grids. However, power-electronic-based inverters have limited overcurrent capability, so additional overcurrent

Impedance Circuit Model of Grid-Forming Inverter: Visualizing Control Algorithms as Circuit Elements
IEEE transactions on power electronics, 2021 The impedance model is widely used for analyzing power converters. However, the output impedance is an external representation of a converter system, i.e., it compresses the entire dynamics into a single transfer function with internal details of the ...

Direct AC voltage control for grid-forming inverters [PDF]
Journal of Power Electronics, 2019 Grid-forming inverters usually use inner cascaded controllers to regulate output AC voltage and converter output current. However, at the power transmission system level where the power inverter bandwidth is limited, i.e., low switching frequency, it is difficult to tune controller parameters to achieve the desired performances because of control loop ...

Synchronization of Inverters in Grid Forming Mode
IEEE Access, 2022 This article compares two strategies for seamless (re)connection of grid-forming inverters to a microgrid powered by droop-controlled inverters. While an incoming inverter must be synced to the microgrid, seamless syncing and power-sharing are technical challenges for grid-forming inverters.

Voltage Balancing Capability of Grid-Forming Inverters
IEEE Open Access Journal of Power and Energy, 2022 The objective of this paper is to analyze and identify the range of voltage balancing capability of grid-forming inverters serving three-phase unbalanced loads. These inverters are designed to compensate for voltage imbalance by controlling the negative-sequence components of voltage and current.
