Although photovoltaic power plants are suitable local energy sources in Micro Grid environments, when large plants are involved, partial shading and inaccurate modelling of the plant can affect both the design of the Micro Grid as well as the energy management process that allows for lowering the overall Micro Grid demand towards the main grid. To investigate the issue, a Photovoltaic Plant sim...

In 2004 the Power Systems and High Voltage Laboratories at ETH initiated the research project ”Vision of Future Energy Networks” (VoFEN), which applies a greenfield approach to the design of future energy systems. The main aspect of the project is the consideration of multiple energy carriers, i.e. the analysis is not restricted to electricity but also considers other energy carriers such as na...

Microbial populations adapt to environmental fluctuations through random switching of fitness-related traits in individual cells. This increases the likelihood that a subpopulation will be adaptive in a future milieu. However, populations are particularly challenged when several environment factors change simultaneously. We suggest that a population can rapidly adapt to multiple environmental c...

Energy hub systems integrate various energy sources and interconnect different carriers in order to enhance the flexibility of system. In this paper, a cooperative framework is proposed which network hubs collaborate together share their resources reduce costs. Each has several including CHP, boiler, renewable sources, electrical chiller, absorption chiller. Moreover, storages are considered fo...

Abstract The Energyhub@Sea concept is one of the four research applications Space@Sea project funded by EU’s Horizon 2020 program (GA number: 774253). focus this paper evaluation energy demands an self-sufficient maintenance platform at location Helgoland in North Sea. In view this, a standardized modular floater was developed as offshore wind operation and base, which following referred to O&a...

The energy absorption of the wave energy converters (WEC) characterized by a limited stroke length —like the point absorbers developed at Uppsala University—depends on the sea level variation at the deployment site. In coastal areas characterized by high tidal ranges, the daily energy production of the generators is not optimal. The study presented in this paper quantifies the effects of the ch...
