An Alternative Control Structure for Grid-Following Converters of Inverter-Based Resources

IEEE Open Access Journal of Power and Energy, 2023
In this paper, an alternative control structure of grid-following control is proposed and applied in inverter-based resources (IBRs). An IBR’s grid-following control normally employs Power/Voltage (P/V) control strategy to control the output real ...

Impact of Inverter Controls in Small-Signal Stability of Power Systems Dominated by Inverter-Based Resources

IEEE Access
Initiatives to decarbonize contemporary power systems will lead to power systems dominated by inverter-based resources (IBR). These IBRs are broadly classified into grid-following (GFL) and grid-forming (GFM) inverter control regimes.

Power Flow-Based Estimation of Short-Circuit Currents From Inverter-Based Resources

IEEE Open Access Journal of Power and Energy
The generator side of inverter-based resources (IBRs) interfaced with back-to-back converters is electrically decoupled from the grid. During electrical faults, grid-following IBRs behave as voltage-dependent current sources due to grid code requirements

Development of df/dt function in inverters for synthetic inertia

Energy Reports, 2023
The increasing share of renewable energy-based resources in the power grid has a detrimental impact on the power system stability. As these resources are inverter-based, they decrease the overall inertia of the grid.

Fault classification in inverter based resources system using spherical coordinate system

e-Prime: Advances in Electrical Engineering, Electronics and Energy
Modern grid codes require renewable energy source (RES) plants to remain connected with the grid even during fault scenarios. Fault current being comparable to rated full-load output of RES plants, makes timely fault analysis a more challenging task.
