Modelling of a Hydro Power Station in an Island Operation [PDF]
Linköping Electronic Conference Proceedings, 2017 There is a strong focus on new renewable energy sources, such as, solar power, wind energy and biomass, in the con-text of reducing carbon emissions. Because of its maturity, hydropower is often overlooked. However, there is an era of hydro oriented research in improving many aspects of this well established technology.

Avoiding the non-detection zone of passive loss-of-mains (islanding) relays for synchronous generation by using low bandwidth control loops and controlled reactive power mismatches [PDF]
, 2014 Generation connected to electrical distribution systems requires reliable and timely detection of loss of-mains (islanding). Passive loss of mains detection relays typically use measurements of parameters such as frequency, phase, and the magnitudes of ...

A Bankruptcy Problem Approach to Load-shedding in Multiagent-based Microgrid Operation
Sensors, 2010 A microgrid is composed of distributed power generation systems (DGs), distributed energy storage devices (DSs), and loads. To maintain a specific frequency in the islanded mode as an important requirement, the control of DGs’ output and charge action ...

Entanglement island, miracle operators and the firewall [PDF]
Journal of High Energy Physics, 2022 Abstract In this paper, we obtain some general results on information retrieval from the black hole interior, based on the recent progress on quantum extremal surface formula and entanglement island. We study an AdS black hole coupled to a bath with generic dynamics, and ask whether it is possible to retrieve information about a ...
