Supercapacitor‐based coordinated synthetic inertia scheme for voltage source converter‐based HVDC integrated offshore wind farm

IET Energy Systems Integration
A supercapacitor‐based coordinated synthetic inertia (SCSI) scheme for a voltage source converter‐based HVDC (VSC‐HVDC)‐integrated offshore wind farm (OWF) is proposed.

Phasing Out Coal Power Through Cross‐Border Renewable Energy Trade in the Asia‐Pacific

Sustainable Development, EarlyView.
ABSTRACT Coal remains the backbone of electricity generation in the Asia‐Pacific region, accounting for half of total regional output and two‐thirds of global coal‐fired capacity. The substantial environmental and public‐health externalities of coal highlight the urgent need to accelerate the renewable energy transition.

Empirical Physics‐Based Normal Behavior Modeling of Drive Train Temperatures With High‐Resolution Wind Turbine Operating Data

Wind Energy, EarlyView.
ABSTRACT The installed wind energy capacity increases every year. However, operation and maintenance costs still make up a considerable portion of the levelized costs of electricity. This costs can be greatly reduced by the application of suitable early fault detection methods. The supervisory control and data acquisition system of wind turbines is one

A vector auto-regressive model for onshore and offshore wind synthesis incorporating meteorological model information [PDF]

, 2014
The growth of wind power production in the electricity portfolio is striving to meet ambitious targets set, for example by the EU, to reduce greenhouse gas emissions by 20% by 2020. Huge investments are now being made in new offshore wind farms around UK

Coordinated frequency support strategy for VSC-HVDC integrated offshore wind farm system

Frontiers in Energy Research
The large-scale offshore wind power integrated into the onshore power grid through voltage source converter-based high voltage direct current (VSC-HVDC) system is unable to provide inertia response and frequency support to the onshore power grid.

An Overview of High‐Temperature Superconducting Cables in DC Systems: Unlocking Potential for High‐Voltage DC Networks

High Voltage, EarlyView.
ABSTRACT This paper provides an overview of high‐temperature superconducting (HTS) cables in DC systems, with a focus on their deployment in high‐voltage DC (HVDC) networks. The assessment of HTS cable properties—such as extremely low electrical resistance, high current‐carrying capacity and a compact geometry—and their comparison with those of ...

300 Years of Degradation in Wales Estuaries and Coasts

Natural Resources Forum, EarlyView.
ABSTRACT The world's oceans are in a severe state of degradation, yet our understanding of that degradation is often based on changes observed only in the past 20–50 years. This narrow view leads to marine conservation efforts that aim to preserve already degraded ecosystems, shaped by shifted ecological baselines.

Hox Gene Variation Drives Morphological Specialization of Humpback Grouper Cromileptes altivelis

Integrative Zoology, EarlyView.
Cromileptes altivelis exhibits a distinctive “sunken head and humpback” morphology, formed through cranial remodeling. Genetic analyses identified unique amino acid variants in Hoxa7a and Hoxa10b, with functional tests confirming their role in enhancing osteoblast activity and driving cranial remodeling.

Macau as Method: Recombinant Urbanism in Post‐Socialist China

Asia Pacific Viewpoint, EarlyView.
ABSTRACT In ‘Asia as Method’, Chen Kuan‐Hsing argues for the value of an indigenous inter‐Asian approach to analysing the effects of European imperialism on the countries and citizens of Asia. This article mobilises both Chen's inter‐Asian referencing strategy and the city‐state of Macau to explore Macau's role in China's engagements with global ...
