1. 16. Insights from modeling renewable electricity systems and developing hydropower models

   Författare :Hanna Ek Fälth; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; renewables; electricity systems; hydropower; nuclear; modeling; Europe; MENA; transmission; available land;

   Sammanfattning : One strategy for reaching a carbon-neutral electricity system is a large-scale deployment of wind and solar power. However, electricity systems with high shares of wind and solar power rely on other technologies, e.g. LÄS MER

3. 17. Combined heat and power plant flexibility - Technical and economic potential and system interaction

   Författare :Johanna Beiron; Chalmers tekniska högskola; []
   Nyckelord :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;

   Sammanfattning : 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. 18. Combined heat and power plants in decarbonized energy systems: Techno-economics of carbon capture and flexibility services at the plant, city and regional levels

   Författare :Johanna Beiron; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Negative emissions; Flexibility; CCS; District heating; Energy system modeling; Combined heat and power; Techno-economic assessment;

   Sammanfattning : Our present energy system is the main driver of climate change. Variable renewable electricity generation and carbon dioxide removal (CDR) are key technologies in the transformation to a sustainable energy system, but their broad implementation implies challenges related to energy system flexibility and energy requirements of CDR technologies.

5. 19. Energy analysis for sustainable mega-cities

   Författare :Aumnad Phdungsilp; Björn Palm; Ivo Martinac; Charles Heaps; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Asian mega-cities; energy demand; metabolism of cities; energy modeling; sustainable energy; energy planning; multi-criteria decision-making; Mechanical energy engineering; Mekanisk energiteknik;

   Sammanfattning : ABSTRACT Cities throughout Asia have experienced unprecedented economic development over the past decades. In many cases this has contributed to their rapid and uncontrolled growth, which has resulted in a multiplicity of problems, including rapid population increase, enhanced environmental pollution, collapsing traffic systems, dysfunctional waste management, and rapid increases in the consumption of energy, water and other resources.

7. 20. Exploring the future low-carbon electricity system: impacts of nuclear power and demand patterns

   Författare :Xiaoming Kan; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; net system cost; electricity supply mix; Low-carbon electricity system; variable renewable energy; nuclear power; electricity system cost; demand pattern; energy system modeling;

   Sammanfattning : To achieve the climate goals set by the Paris Agreement, the global electricity system is expected to transition towards a low-carbon electricity system. The future low-carbon electricity system is uncertain regarding both generation and demand. LÄS MER
