Dynamical Modeling and Control of Multiphase Heat Transport Systems Based on Loop Heat Pipes


Book Description

Effective heat transport systems in aerospace are based on multiphase loop heat pipes (LHPs). For a precise thermal control of the electronics, electrical heaters are additionally used to control the operating temperature of the LHP. This work focusses on the dynamical modeling and model-based control design for LHP-based heat transport systems. The results of this work can be used for the optimization of current control parameters and the efficient control design for future LHP applications.




Transactive Control of Coupled Electric Power and District Heating Networks


Book Description

Der Entwurf von Ansätzen zur marktbasierten Betriebsführung zukünftiger Energienetze steht vor der technischen Herausforderung, eine enorme Anzahl von Netzteilnehmern zeitlich und örtlich zu koordinieren, um Erzeugung und Verbrauch auszugleichen und einen sicheren Netzbetrieb zu ermöglichen. Um dieser Herausforderung zu begegnen entstand das Forschungsfeld der Transactive Control Ansätze. In dieser Arbeit wird ein neuer Transactive Control Ansatz für gekoppelte Strom- und Wärmenetze vorgestellt. - The design of approaches for future market-based energy network operation faces the technical challenge of needing to coordinate a vast number of network participants spatially and temporally, in order to balance energy supply and demand, while achieving secure network operation. To meet this challenge, the research field of transactive control emerged. Within this work a new transactive control approach for coupled electric power and district heating networks is presented.
