  2. 1. Solar PV in prosumer energy systems : A techno-economic analysis on sizing, integration, and risk

    Author : Nelson Sommerfeldt; Hatef Madani Larijani; Björn Palm; Michel Haller; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrify everything; building energy systems; energy systems analysis; solar heat pump; investment analysis; Monte Carlo analysis; PVT; solar hybrid; Electrify everything; byggnadsenergisystem; energisystemanalys; solvärmepump; investeringsanalys; Monte Carlo analys; PVT; solhybrid; Energy Technology; Energiteknik; Planering och beslutsanalys; Planning and Decision Analysis;

    Abstract : In the transition towards a sustainable energy system, building mounted solar photovoltaics (PV) have unique benefits; they require no additional land and the energy is generated directly at load centers. Within residential buildings, multi-family homes (MFH) are particularly interesting because of the economies of scale and their greater potential for emissions reductions. READ MORE

  4. 2. Applications of artificial neural networks for time series data analysis in energy domain

    Author : Fan Zhang; Hasan Fleyeh; Stawomir Nowaczyk; Högskolan Dalarna; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Deregulated energy market; electricity prices; district heating; energy efficiency; neural networks; Complex Systems – Microdata Analysis; Komplexa system - mikrodataanalys;

    Abstract : With the development of artificial intelligence techniques and increased installation of smart meters in recent years, time series analysis using historical data in the energy domain becomes applicable. In this thesis, microdata analysis approaches are used, which consist of data acquisition, data processing, data analysis and data modelling, aiming to address two research problems in the energy domain.

  5. 3. Production planning of CHP plants integrated with bioethanol production and local renewables

    Author : Mahsa Daraei; Eva Thorin; Anders Avelin; Erik Dotzauer; Natasa Nord; Mälardalens högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CHP; Energy systems; Optimization; Polygeneration; Production planning; Renewable resources; Energy- and Environmental Engineering; energi- och miljöteknik;

    Abstract : Production planning of an energy system is dependent on parameters such as energy demand and energy conversion technologies, which are influential in making decisions on operation strategy and optimal performance of the system. In accordance with the European Union energy policy, the share of renewable resources in the energy supply is growing. READ MORE

  6. 4. Hybrid energy storage systems : Capacity optimization and environmental implication of hybrid energy storage systems in renewable power systems

    Author : Yang Jiao; Daniel Månsson; Alfred Rufer; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical Engineering; Elektro- och systemteknik;

    Abstract : Electricity production contributes a large share of greenhouse gas emissions that lead to climate change. At present, power generation in many parts of the world still heavily depends on fossil fuels. To prevent global warming, the electricity sector is supposed to transition from the current fuel mix to renewable energy sources. READ MORE
