Energy Science &Engineering, Volume 14, Issue 3, Page 1286-1299, March 2026.This work proposes a high‐fidelity, simulation‐driven control framework for robust grid integration of hybrid PV–wind systems using a modular, hierarchical multi‐loop architecture with adaptive decision logic. The framework coordinates power, DC‐link voltage, and grid currents under fast load and generation changes, enabling safe exploration of extreme

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

Energy Science &Engineering, Volume 14, Issue 3, Page 1505-1528, March 2026.This study presents a hierarchical coordination framework where multiple VPPs interact with the DSO to optimize energy trades and flexibility offers. Each VPP aggregates DERs and DR, performing internal optimization, day‐ahead bidding, and assessing flexibility to reduce excess renewable generation and pollution.

High Voltage DC Active Current Injection to Simulate Geomagnetically Induced Currents in New Zealand
Space Weather, Volume 24, Issue 3, March 2026.Abstract This study investigates the effects of geomagnetically induced currents (GIC) on New Zealand's electrical infrastructure via an intentional ground injection of direct current (DC) from a high voltage DC converter station. GIC manifests as quasi‐DC currents within power systems, potentially causing transformer saturation, increased reactive ...

High Voltage, Volume 11, Issue 1, Page 305-315, February 2026.ABSTRACT The proliferation of ultra‐high voltage direct current (UHVDC) transmission technology has heightened regulatory oversight of electromagnetic fields around buildings. In conventional direct current (DC) line design, the presence of residential areas was typically not taken into account.
