1. 1. Small-Scale Decentralized Energy Systems : optimization and performance analysis

   Författare :Sara Ghaem Sigarchian; Viktoria Martin; Anders Malmquist; Erik Dahlquist; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Small-scale polygeneration energy systems; techno-economic optimization; renewable energy; operating strategy; particle swarm optimization; optimization algorithm; decentralized energy system;

   Sammanfattning : Small-scale polygeneration energy systems, providing multiple energy services, such as heating, electricity, cooling, and clean water, using multiple energy sources (renewable and non-renewable) are considered an important component in the energy transition movement. Exploiting locally available energy sources and providing energy services close to the end users have potential environmental, economic, and societal benefits. LÄS MER

3. 2. Island-based Polygeneration Systems : On the Feasibility of Solar-Biomass-driven Distributed Concepts

   Författare :Moritz Wegener; Anders Malmquist; Andrew R. Martin; Antonio Isalgué; Natasa Nord; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Polygeneration; Distributed energy systems; Biomass; Solar energy; PV-Battery; Small-scale energy systems; techno-economic analysis; Island-based systems; Energy Technology; Energiteknik;

   Sammanfattning : The colossal risks and challenges posed by climate change require innovative solutions that must fulfil energy service demands sustainably. The concept of small-scale, biomass-based polygeneration (SBP) is one such technological approach, which optimizes locally supplied fuels to provide several energy services like electricity, heating, cooling, potable water, and/or bio-chemical products.

4. 3. Decentralization in the electricity system: At the household, community and city levels

   Författare :Verena Heinisch; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Smart city; Storage systems; Power-to-heat; Optimization; Energy system modeling; Photovoltaic; Decentralization; Community energy; Prosumers;

   Sammanfattning : Recent years have seen a rise in the number of implementations of small-scale generation and storage technologies for electricity and heat at different levels in the energy system. This trend towards decentralization of the system is driven by rapid decrease in technology costs, as well as the intentions expressed by various stakeholders to contribute to a carbon-neutral energy system.

5. 4. Electrification of rural Mozambique : Sustainable energy solutions

   Författare :Miguel Meque Uamusse; Avdelningen för Teknisk vattenresurslära; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Renewable energy; hydropower potential; Rural electrification; mini-grid; biomass; climate change effects;

   Sammanfattning : The UN Sustainable Development Goal (SDG) 7 states that access to affordable, reliable, sustainable, and modern energy should be provided for all by 2030. The effects on socioeconomic development by access to safe, affordable, and clean electricity stands out as educational benefits, income improvement, and health progress. LÄS MER

7. 5. On the Analysis and Fault-Diagnosis Tools for Small-Scale Heat and Power Plants

   Författare :Jaime Arriagada; Kraftverksteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Thermal engineering; applied thermodynamics; Termisk teknik; termodynamik; genetic algorithms; neural networks; fault diagnosis; maintenance; availability; reliability; energy analysis; combined heat and power; Methods and tools; small scale;

   Sammanfattning : The deregulation of the electricity market drives utilities and independent power producers to operate heat and power plants as profit centers. In order to keep the economic margins on the credit side, the preferred measures have been to improve the electrical efficiency through changes in the hardware and boost the overall efficiency through e.g. LÄS MER
