2. 1. Balancing variable renewable electricity generation using combined heat and power plants, large-scale heat pumps, and thermal energy storages in Swedish district heating systems

   Author : Svante Monie; Magnus Åberg; Annica Nilsson; Joakim Widén; Magnus Wallén; Uppsala universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; District heating systems; Power-to-Heat; Heat pumps; Combined heat and power; Thermal energy storage; Power balance; Variable renewable electricity; Biomass fuel; Engineering Science with specialization in Civil Engineering and Built Environment; Teknisk fysik med inriktning mot byggteknik och byggd miljö;

   Abstract : The global ambitions to hamper the greenhouse effect has led to ambitious targets for increasing renewable energy use. This, in combination with recent years' vast development of wind and solar power, implies that there will be significant amounts of variable renewable electricity (VRE) in future energy systems.

4. 2. Combined heat and power plant flexibility - Technical and economic potential and system interaction

   Author : Johanna Beiron; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Combined heat and power; Flexibility; Process optimization modeling; Electricity price volatility; Waste to energy; Combined cycle; District heating; Dynamic modeling;

   Abstract : The share of variable renewable energy sources in electricity generation systems is expected to increase, leading to increased variability in the load that must be provided by conventional power plants or other flexibility measures. Thus, thermal power plants need to consider implementation of technical measures that enhance flexibility; to maintain profitability of operation with increased electricity price fluctuation, and to support electricity system stability.

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

   Author : Jaime Arriagada; Kraftverksteknik; []
   Keywords : 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;

   Abstract : 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. READ MORE

6. 4. Thermodynamic analysis of Stirling engine systems : Applications for combined heat and power

   Author : Joseph Adhemar Araoz Ramos; Torsten Fransson; Carlos Augusto Santos Silva; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Stirling engine; Thermodynamic analysis; Energiteknik; Energy Technology;

   Abstract : Increasing energy demands and environmental problems require innovative systems for electrical and thermal energy production. In this scenario, the development of small scale energy systems has become an interesting alternative to the conventional large scale centralized plants. READ MORE
