GridVille NTNU – Sustainable Power By Students

GridVille NTNU er en studentorganisasjon ved NTNU som jobber med smarte og bærekraftige energiløsninger. Gjennom praktiske prosjekter får medlemmene erfaring med fornybar energi, mikronett og energistyring. Gruppen fokuserer på læring, samarbeid og anvendelse av eksisterende teknologi i reelle prosjekter. Nå skal vi installere et energisystem på en DNT-hytte for å teste løsningene i krevende omgivelser.

Hyt-t-ing – "Re-imagining cabin culture for the regeneration of socio-ecological systems."

Katy takes a holistic approach towards cabin culture and the future of how we want to shape this tradition. She uses design thinking and co-design workshops for her research, to involve a broad audience and stakeholders. This presentation gives valuable insights in several aspects of re-thinking our cabin culture.

Effects of battery degradation modelling on sizing of off-grid PV-battery systems

In this presentation, preliminary results of our off-grid PV-battery system analysis are shown. Our aims are to (1) find the PV and battery sizes that would allow self-sufficiency for the off-grid loads, and (2) investigate how different battery degradation models affect the estimated battery lifetimes and sizing of the system. Especially, the implementation and comparison of the battery degradation models bring novel insights on the longevity of off-grid batteries, since the influence different battery degradation modes (cyclic and calendar) is often overlooked. Using four different cottage load patterns, we show that 100% self-sufficiency is achieved for battery capacities of 24-32 kWh and PV capacities of 6-20 kWp, while 98% self-sufficiency requires 8-12 kWh smaller battery and 2-10 kWp smaller PV. Different degradation models can have fourfold differences in the calculated battery degradation during the time-frame of one year. The reasons for these discrepancies together with a comparison of the five models used in our analysis will be presented.
