Hierarchical Predictive Control of Microgrids in Islanded Operation
IEEE Transactions on Automation Science and Engineering, 2017 This paper presents a hierarchical control architecture for the regulation of frequency and nodal voltages of a microgrid in islanded operation. Considering systems with both dispatchable and nondispatchable generation, as well as noncontrollable loads, the suggested approach allows to coordinate the MG devices in order to maintain the network ...

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.

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 ...
