2. 1. 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.

4. 2. Advancing formative control room system evaluation – Decision support for human factors evaluation planning and method development

   Author : Eva Simonsen; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; human factors; nuclear power; control room system; design; formative evaluation methods;

   Abstract : The design of the nuclear power plant (NPP) control room system affects the operation of the plant it controls, as well as the well-being of its operators. One important activity in control room system development is Human Factors (HF) evaluation. Previous research indicates that HF evaluation practice for NPP control room systems can be improved.

5. 3. Shaping Future Opportunities for Biomass Gasification - The Role of Integration

   Author : Johan Ahlström; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; hydrogen; heat integration; Gasification; sawmill; SNG; power-to-gas; Biomethane; Biorefinery; process integration;

   Abstract : A considerable number of studies indicate that biofuels produced from lignocellulosic biomass will most probably play a significant role in achieving the climate goals stated in the Paris agreement. Several candidate technologies could be implemented to produce these fuels, and one of the most promising is thermal gasification. READ MORE

6. 4. Technical and Economic Conditions for Efficient Implementation of CO2 Capture - process design and operational strategies for power generation and process industries

   Author : Stefanìa Òsk Gardarsdòttir; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Post-combustion; CCS; chemical absorption; dynamic modeling; industrial sources; CO2 capture and storage; variable electricity generation;

   Abstract : This thesis investigates the operational parameters of fossil-based power generation and industrial processes in future energy systems that have stringent constraints on CO2 emissions, and, consequently, large shares of renewable energy. CO2 capture and storage, which is the focus of this work, is required for power and industrial processes that emit CO2. READ MORE

7. 5. Electricity Distribution Network Planning Considering Distributed Generation

   Author : Yalin Huang; Lennart Söder; Karin Alvehag; Peiyuan Chen; KTH; []
   Keywords : Electricity distribution network; network planning; distributed generation; Electrical Engineering; Elektro- och systemteknik;

   Abstract : One of EU’s actions against climate change is to meet 20% of our energy needs from renewable resources. Given that the renewable resources are becoming more economical to extract electricity from, this will result in that more and more distributed generation (DG) will be connected to power distribution.
