  1. 1. Energy-Efficient Fixed-Coefficient FIR Filters for Millimeter-Wave Radios

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Institutionen för reglerteknik

    Författare :Erik Lundell; Gustav Molin; [2023]
    Nyckelord :Technology and Engineering;

    Sammanfattning : With the introduction of millimeter-wave antenna arrays in 5G base-stations and ever-increasing data volumes, the power consumption of the signal processing in digital radio systems has increased over the last decade. This, combined with increased cost and environmental awareness, has put focus on power optimization. LÄS MER

  3. 2. Technical performance modelling and optimization of PVT collectors in GSHP integration

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Marin Courcault; [2023]
    Nyckelord :PVT; ISO9806:2017; mass flow; use conditions; test conditions; coefficients optimization; TRNSYS; PVT; ISO9806:2017; massflöde; användningsförhållanden; testförhållanden; optimering av koefficienter; TRNSYS;

    Sammanfattning : In order to contribute to reducing the CO2 emissions related to heating in housing buildings, PVT+GSHP systems appear to be interesting solutions and therefore need to be further investigated to optimise their design and increase their deployment on the field. This thesis focused on building PVT model, using the ISO9806:2017, to be integrated in a PVT+GSHP model and determining optimal PVT design parameters for this system. LÄS MER

  4. 3. Simulating distributed PV electricity generation on a municipal level : Validating a model for simulating PV electricity generation and implementing it for estimating the aggregated PV generation in Knivsta Municipality

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Byggteknik och byggd miljö

    Författare :Lisa Molin; Sara Ericson; [2023]
    Nyckelord :photovoltaic generation model; model validation; artificial intelligence; machine learning; convolutional neural network; LIDAR;

    Sammanfattning :   The deployment of distributed photovoltaic (PV) is accelerating worldwide. Understanding when and where PV systems will generate electricity is valuable as it affects the power balance in the grids. One way of obtaining this information is simulating the PV power production of systems detected in Remotely Sensed Data (RSD). LÄS MER

  5. 4. Utveckling av driftstöd för planering av fjärrkyla : En explorativ studie om utvecklingen av ett optimeringsbaserat driftplaneringsverktyg för fjärrkylanätet City i Linköping, Sverige

    Master-uppsats, Linköpings universitet/Energisystem

    Författare :Christian Haapanen; Louise Hedenskog; [2023]
    Nyckelord :District cooling; MILP; UC problem; Optimization; Operational plan; Smart energy systems; Fjärrkyla; MILP; UC problem; Optimering; Driftplanering; Smarta energisystem;

    Sammanfattning : The average global temperature is rising due to climate change. This leads to an increase in cooling demand along with higher usage of electricity to operate cooling processes. One way to decrease the electricity usage is to introduce absorption cooling which uses heat instead of electricity as its main source of power. LÄS MER

  7. 5. Optimal joint operation of wind and hydropower

    Master-uppsats, Stockholms universitet/Institutionen för data- och systemvetenskap

    Författare :Evangelos Bikis; [2022]
    Nyckelord :VRES integration; hydropower; wind power; business analytics; optimization; linear programming; clustering;

    Sammanfattning : Climate change drives policymakers to reduce emissions and enhance the integration of variable renewable energy sources (VRES) into the power system. Wind power is considered among the most beneficial VRES as it can generate cost-effectively carbon-free electricity but comes with inherent intermittency. LÄS MER
