Frequency regulation participation of offshore wind farm integrated by diode-rectifer HVDC system
The Journal of Engineering, 2019 Large-scale wind farms integrated with multi-terminal direct current (MTDC) system decouples the frequency between the wind farms and the receiving end, resulting in weakened frequency regulation ability of the onshore AC grid. Recently a new topology is

SusMat, Volume 2, Issue 6, Page 731-748, December 2022., 2022 A thermodynamic assessment of the stability of FeNx sites in Fe/N/C catalysts suggests that a FeN(4+2)/C hexa‐aza‐type site is much less prone to demetallation during oxygen reduction reaction in PEM fuel cell than a FeN4/C‐type site. Abstract We present here a thermodynamic assessment of the stability behavior in acid environment at 298 and 353 K (80 ...

Voltage over‐scaling CNT‐based 8‐bit multiplier by high‐efficient GDI‐based counters
IET Computers &Digital Techniques, Volume 17, Issue 1, Page 1-19, January 2023., 2023 A new low‐power and high‐speed multiplier is presented based on voltage over scaling (VOS) technique and new 5:3 and 7:3 counter cells. VOS technique is used to reduce power consumption in digital circuits, but different voltage levels of the VOS increase the delay in different stages of a multiplier.
