Series Transformer Inrush Current Reduction in DVR Using Metaheuristic Optimisation Algorithms in Presence of Balanced and Unbalanced Voltage Sags

IET Electric Power Applications, Volume 20, Issue 1, January/December 2026.
In this paper, a PI controller is improved for DVR to compensate voltage drops and reduce the series transformer inrush current effectively. The controller parameters are optimised using the modified arctic puffin optimisation (MAPO) algorithm in order to improve the performance of DVR.

Research on Voltage Regulation Methods for Flexible On‐Load Tap‐Changing Transformers

Electrical Materials and Applications, Volume 3, Issue 1, January/December 2026.
The control system determines whether the output voltage magnitude of the voltage source converter (VSC) is high, low or constant and generates the corresponding pulse signals. Each pulse is generated at the valve‐triggering instant, with its width corresponding to the commutation angle.

HVDC Transmission with STATCOM

IOSR Journal of Engineering, 2012
Most of the HVDC power converters with thyristor valves are assembled in a converter Bridge of Six pulse configuration. Converter transformers with one DC side winding as an ungrounded star connection and the other a delta configuration. Comparative studies of the two systems of HVDC CIGRE model without STATCOM and with STATCOM were performed. In these

Impedance Matching Control of Grid‐Forming Energy Storage Converter for Improving the Stability of the Renewable Energy Stations

IET Energy Systems Integration, Volume 8, Issue 1, January/December 2026.
ABSTRACT Increased penetration of power converters within electrical power systems frequently induces resonance issues, which can often be mitigated by reshaping the output impedance of renewable energy sources (RES). From the perspective of feasibility and cost‐effectiveness, the energy storage converter (ESC), which is already integrated into most ...
