DC-Bus Voltage Control Stability Affected by AC-Bus Voltage Control in VSCs Connected to Weak AC Grids (2016, methodology): “As declared in [12], weak ac system deteriorates dc-bus”
Modeling and Control of VSC-HVDC Links Connected to Island Systems (2011, methodology): “The fundamental idea of power-synchronization control of grid-connected VSCs is that VSCs synchronize with the ac system through the active-power control instead of using a phase-locked loop (PLL), similar to the operation of a synchronous machine [6], [8].”
Modeling of Multi-Terminal VSC HVDC Systems With Distributed DC Voltage Control (2014, background): “As the control of the DC voltage is crucial to the operation of the power system, one can therefore duplicate the DC voltage control, as proposed in [21] and elaborated in [23] for the power synchronization control, and mentioned in [24] for the operation of a two-terminal scheme.”
Large Signal Synchronizing Instability of PLL-Based VSC Connected to Weak AC Grid (2019, positive): “Yet, when VSC is connected to weak ac grid, terminal voltage becomes vulnerable [6] and thus interaction of VSC and grid is aggravated, which may deteriorate the performance of PLL and bring the synchronizing instability.”
Modeling and Control of VSC-HVDC Links Connected to Weak AC Systems (2010, background): “Some results of this chapter are included in [63, 86].”

Current Limiting Control With Enhanced Dynamics of Grid-Forming Converters During Fault Conditions (2020, background): “Among the grid-forming converters, numerous control schemes exist: droop control [6], [7], Virtual Synchronous Machine (VISMA/VSM) [8], [9], synchronverter [10]–[12], Power Synchronization Control (PSC) [13], [14] and Synchronous Power Controller (SPC) [15], [16].”
Robust Vector Control of a Very Weak-Grid-Connected Voltage-Source Converter Considering the Phase-Locked Loop Dynamics (2017, background): “In a weak-grid connection, ac-bus voltage control yields higher stability margins are compared to the reactive power injection mode [15].”
Grid-Synchronization Stability of Converter-Based Resources—An Overview (2020, neutral): “have revealed that the grid-forming control achieves superior stability in weak grids compared to the grid-following control [52], since the PLL is not needed for grid-forming control, and”
Analysis of Stability Limitations of a VSC-HVDC Link Using Power-Synchronization Control (2011, background): “In addition, as it is shown by [15], the ac capacitor in fact does not affect the stability limitation of the VSC-HVDC link.”
An Overview of Assessment Methods for Synchronization Stability of Grid-Connected Converters Under Severe Symmetrical Grid Faults (2019, positive): “against weak grid conditions including power synchronization control [55], or any other control with the objective to emulate a synchronous machine.”
Analysis and Performance Enhancement of Vector-Controlled VSC in HVDC Links Connected to Very Weak Grids (2017, methodology): “The modeling of a VSC has been discussed by many researchers [9], [10], [19]–[28].”
