1. 1. The climate impact of fishways : A life cycle assessment of Blyberg’s and Spjutmo’s up- and downstream fishways

   Master-uppsats, Linköpings universitet/Industriell miljöteknik

   Författare :Ellen Lundin; Lovisa Liljenberg; [2023]
   Nyckelord :LCA; life cycle analysis; life cycle assessment; fishways; fish; fish migration; climate impact; technical fishways; co2 equivalents; co2 eq; hydro power; HPP; Sweden; construction; concrete; reinforcement steel;

   Sammanfattning : The Swedish national plan for reapproval of hydropower describes that hydropower plants (HPPs) are required to be reassessed to ensure that modern environmental conditions are set for the permits. Since dams and HPPs create barriers for migrating fish and consequently disfavor biological diversity, one consequence of the national plan is that fishways are being constructed. LÄS MER

3. 2. Optimisation of Run of River Production Forecasting Using Aiolos Forecast Studio

   Master-uppsats, Lunds universitet/Avdelningen för Teknisk vattenresurslära

   Författare :Amer Al-Qes; [2020]
   Nyckelord :Run of river hydropower plants; power production forecasting; Aiolos forecast studio; model accuracy assessment analysis and power market.; Technology and Engineering;

   Sammanfattning : Hydropower is simply the largest source of renewable energy in the Nordic countries, where It compose around 90% of power production in Iceland, 70% in Norway, 40% in Sweden and 20% in Finland. Mountainous terrain and abundance in the surface water is a significant contributing factor in hydropower production. LÄS MER

4. 3. Local Impacts of Climate Change on Fortum´s Hydropower Production

   Master-uppsats, KTH/Vattendragsteknik

   Författare :Joakim Thanke Wiberg; [2016]
   Nyckelord :Global warming; climate variability; hydropower plants; spectral analysis;

   Sammanfattning : Background: Climate change and the consequences of global warming is probably one of the greatest issues of our time. Among other concerns, global warming is thought to have a great impact on hydrology worldwide. When the atmosphere warms up, river runoff patterns are altered. LÄS MER

5. 4. To dam or not to dam : a case study of conflict surrounding the Collinsville Dams and implications for the future

   Master-uppsats, Lunds universitet/LUCSUS

   Författare :Laura Hart; [2014]
   Nyckelord :Farmington River; Collinsville Dams; run-of-river hydropower; local renewable energy; sustainability science; Social Sciences;

   Sammanfattning : Hydroelectric power is a controversial renewable energy. Adding more renewables to the energy mix is becoming more critical with the onslaught of climate change, while river health and water quality remain a highly pertinent environmental issue. Balancing the need for local renewable energy and environmental concerns is the topic of many cases. LÄS MER

7. 5. Analysis of a load frequency control implementation in Swedish run-of-river hydropower stations

   Uppsats för yrkesexamina på avancerad nivå, Elektricitetslära

   Författare :Andreas Westberg; [2012]
   Nyckelord :Hydropower; power system; frequency controlled reserves; load frequency control; Matlab Simulink;

   Sammanfattning : The total amount of frequency deviations have during the last decade increased exponentially in the Nordic synchronous power system. The transmission system operators have therefore decided to implement load frequency control as a new automatic control system to stem these frequency deviations. LÄS MER
