1. 1. Peak Load Shaving Strategies of an Office Building : A Case Study at AirSon

   Master-uppsats, Högskolan i Halmstad/Akademin för företagande, innovation och hållbarhet

   Författare :Azin Farzam; [2024]
   Nyckelord :Shifting Peak Load; Electricity Reduction; Measuring Peak Load; Electricity Efficiency; Building Management System; Electricity Consumption.;

   Sammanfattning : Introduction: The global demand for renewable energy is expected to grow annually due to rising electricity consumption and economic and regulatory incentives. Efficient consumption and management of electricity consumption can support this trend (shifting from fossil resources to renewable resources) and benefit companies economically by reducing peak loads, reducing subscription costs, and protecting companies' power systems and networks.

3. 2. Predicting Electricity Consumption with ARIMA and Recurrent Neural Networks

   Kandidat-uppsats, Uppsala universitet/Statistiska institutionen

   Författare :Klara Enerud; [2024]
   Nyckelord :time series forecasting; ARIMA; recurrent neural networks; LSTM; electricity forecasting; EED forecasting;

   Sammanfattning : Due to the growing share of renewable energy in countries' power systems, the need for precise forecasting of electricity consumption will increase. This paper considers two different approaches to time series forecasting, autoregressive moving average (ARMA) models and recurrent neural networks (RNNs). LÄS MER

4. 3. Integrating Waste Heat from Hydrogen Production Into District Heating

   Master-uppsats, Lunds universitet/Institutionen för energivetenskaper

   Författare :Fawzi Kayali; [2023]
   Nyckelord :Hydrogen; Electrolysis; Waste Heat Recovery; Combined Heat and Power Plant; District Heating; Simulation; Sustainable Heating Systems; Technology and Engineering;

   Sammanfattning : The aim of this research is to explore the feasibility of the integration of waste heat from electrolyzers within a Combined Heat and Power (CHP) plant and district heating (DH) network and suggest a practical setup for integration. With the escalating emphasis on the development of green hydrogen through electrolysis powered by renewable energy, a substantial amount of waste heat is generated, typically left unused. LÄS MER

5. 4. Techno-economic analysis and simulation of low temperature district heating networks

   Master-uppsats, Lunds universitet/Avdelningen för Energi och byggnadsdesign; Lunds universitet/Institutionen för arkitektur och byggd miljö

   Författare :Ilia Iarkov; [2023]
   Nyckelord :Low-temperature district heating; Modelica; BTES; LCA; LCC; Technology and Engineering;

   Sammanfattning : The continuous increase in global energy consumption has led to a greater focus on the energy required for heating buildings. This thesis presents a techno-economic model for analysing low-temperature district heating networks coupled with a geothermal heat source. LÄS MER

7. 5. Reducerande ventiler i fjärrvärmenätet : Reducerande ventilers påverkan på framtidens fjärrvärmenät

   Uppsats för yrkesexamina på grundnivå, Mittuniversitetet/Institutionen för naturvetenskap, design och hållbar utveckling (2023-)

   Författare :Felix Öhman; [2023]
   Nyckelord :District heating; district heating network; pressure drop; valve; reducing valve; flowrate; NetSim.; Fjärrvärme; fjärrvärmenät; tryckfall; ventil; reducerande ventil; flödeshastighet; NetSim.;

   Sammanfattning : Fjärrvärmen utgör omkring hälften av all uppvärmning som sker i Sverige idag och har utöver det en viktig roll då den tar vara på mycket energi som annars hade gått till spillo. Att kunna vara ekonomiskt konkurrenskraftig gentemot andra uppvärmningsalternativ är en viktig del för fjärrvärmens fortsatta utveckling. LÄS MER
