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

    Författare :Nelson Sommerfeldt; Hatef Madani Larijani; Björn Palm; Michel Haller; KTH; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  3. 2. Exploring low-carbon development pathways for Bolivia - A model-based analysis focused on the energy sector

    Författare :Jenny Gabriela Peña Balderrama; Viktoria Martin; Mark I. Howells; Dilip Khatiwada; Francesco Gardumi; Pachauri Shonali; KTH; []

    Sammanfattning : Global emissions have continued to rise steadily at levels exceeding the 1.5°C climate stabilization target. Therefore, the increase in the average global temperature and climate change will be determined by how we handle greenhouse gas (GHG) emissions over the next years. LÄS MER

  4. 3. Dynamics of Energy Systems - Methods of analysing technology change

    Författare :Lena Neij; Internationella miljöinstitutet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy research; evaluation; market transformation; PV modules; wind power; experience curves; air-distribution; lighting; vintage models; sustainable energy; renewable energy; energy efficiency; Energy; energy system; Energiforskning; Environmental technology; pollution control; Miljöteknik; kontroll av utsläpp;

    Sammanfattning : Technology change will have a central role in achieving a sustainable energy system. This calls for methods of analysing the dynamics of energy systems in view of technology change and policy instruments for effecting and accelerating technology change. In this thesis, such methods have been developed, applied, and assessed. LÄS MER

  5. 4. Advancing Nexus Approaches: insights from practice in support of their operationalisation

    Författare :Eunice Pereira Ramos; Mark Howells; Francesco Gardumi; Vignesh Sridharan; Hans-Holger Rogner; Declan Conway; KTH; []

    Sammanfattning : The last decade has seen the emergence of a new research theme - the study of the resources Nexus. The “Nexus” refers to considering the functioning of several systems simultaneously, as opposed to one, as the object of research. This perspective reasons that coherent decision-making needs to consider systems' interconnectedness. LÄS MER

  7. 5. Energy Savings Using a Direct Current Distribution Network in a PV and Battery Equipped Residential Building

    Författare :Patrik Ollas; Caroline Markusson; Mattias Persson; Torbjörn Thiringer; Jan-Olof Dalenbäck; RISE; []

    Sammanfattning : Energy from solar photovoltaic (PV) are generated as direct current (DC) and almost all of today’s electrical loads in residential buildings, household appliances and HVAC system (Heating Ventilation and Air-conditioning) are operated on DC. For a conventional alternating current (AC) distribution system this requires the need for multiple conversion steps before the final user-stage. LÄS MER
