HVDC systems are playing an increasingly significant role in energy transmission due to
their technical and economic superiority over HVAC systems for long distance transmission …

Conventional vector control (VC) is widely used in the voltage source converter (VSC) due to
its simplicity and power decoupling ability. However, this paper reveals that the VC may …

The integration of renewable energy sources (RESs) is a key objective for energy sector
decision-makers worldwide, aiming to establish renewable-rich future power grids …

This paper addresses robust design of the active-power and dc-link control loops of power-
synchronization control. Robustness is obtained by analytic gain selections, which give …

Voltage source converter (VSC) based high-voltage direct current (hVDC) system is an
emerging technology in high-power applications. Previous research has shown that VSCs …

Stability assessment of conventional vector current control (VCC) of voltage-source
converters (VSCs) in weak grids has not been standardized. In this article, a small-signal …

This paper studies the dynamic behaviors of weak-grid-tied VSCs with simplified transfer
functions, which provides an accurate stability analysis and useful indications for tuning …

Despite attempts to increase the active power capability of vector-controlled voltage source
converters (VSCs) connected to very weak grids, the interaction between the control …

Under weak grid condition, negative influence is brought in on system stability because the
grid impedance and the grid-connected converter control system are coupled to each other …

For the hybrid multi-infeed HVDC system in which the receiving-end grid is a strong AC grid
including LCC-HVDC subsystems and multiple VSC-HVDC subsystems, it has higher …
