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

Fishing Activity Affected Odontocete Cetacean Distribution in a Marine Protected Area in the East China Sea

Integrative Zoology, EarlyView.
Spatiotemporal distribution of odontocete cetaceans within China's Jiushan Archipelago National Nature Reserve was investigated. Fishing vessels significantly reduced both cetacean acoustic detections and feeding activity, whereas gillnets selectively suppressed cetacean feeding behavior without affecting overall cetacean detection rates.

A non-iterative distributed approximate dynamic programming algorithm for frequency security-constrained stochastic economic dispatch

International Journal of Electrical Power & Energy Systems
Due to uncertainties associated with the power output of offshore wind farms, the active power balance and frequency security control of power systems with lots of offshore wind farms are highly challenging.

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 ...

The collective application of shorebird tracking data to conservation

Conservation Biology, EarlyView.
Abstract Addressing urgent conservation issues, such as the drastic declines of North American migratory birds, requires creative, evidence‐based, efficient, and collaborative approaches. The abundance of over 50% of monitored North American shorebird populations has declined by over 50% since 1980. To address these declines, we developed a partnership

Estimating the total mortality of seabirds following a marine heat wave

Conservation Biology, EarlyView.
Abstract Marine heat waves detrimentally affect a range of marine species, including seabirds, and are increasing in frequency and severity. When thousands of dead seabirds wash up on beaches, the public becomes concerned. However, the number of dead birds recorded on beaches is only a fraction of the total mortality; most birds perish at sea.
