A Review of Transient Support and Security‐Stability Enhancement Control Strategies for Grid‐Forming Voltage Source Converter‐Based High Voltage Direct Current Transmission

High Voltage, EarlyView.
ABSTRACT Amid the ongoing global energy transition, the short‐circuit ratios of AC power grids are continuously decreasing. Grid‐forming voltage source converter‐based high voltage direct current transmission (GFM VSC‐HVDC) systems have therefore come to the forefront of attention.

Stability of two-terminal high-voltage direct-current power transmission systems: Nexus between parameters and controls

International Journal of Electrical Power & Energy Systems
The stability of high-voltage direct-current (HVDC) power systems is determined by both parameter variables (e.g., proportional-integral parameters) and control variables (e.g., control references).

Programs for the study of HVDC systems [PDF]

IEEE Transactions on Power Delivery, 1988
It is argued that because HVDC technology has reached a point where multiterminal HVDC systems are being planned and installed, planning and operating studies for systems of this type will become increasingly important. However, most of the tools available for such study are somewhat restricted in capability.

Analysis of Out‐of‐Step Oscillation Centre Migration Under Increasing Renewable Energy Penetration in Large‐Scale Power Systems

IET Smart Energy Systems, EarlyView.
Increasing renewable penetration causes out‐of‐step oscillation centres to migrate away from renewable integration points. Two distinct migration modes—continuous drift and large‐range jumps with instability‐mode changes—are identified, providing guidance for adaptive splitting protection in future power systems.

A Novel Bipolar DC Connection Strategy for Photovoltaic Power Plants With a 50% Reduction in DC Cabling Length

Energy Science &Engineering, Volume 14, Issue 9, Page 4230-4247, September 2026.
Bipolar configuration is a new topology in the direct current (DC) system of photovoltaic power plants, which is topologically analogous to the bipolar configuration utilised in High‐Voltage Direct Current power transmission systems. DC cable length and copper usage are reduced by 50% using a bipolar configuration.
