1. 1. Power to the people : electricity demand and household behavior

   Författare :Mattias Vesterberg; Runar Brännlund; Chandra Kiran Krishnamurthy; Maximilian Auffhammer; Umeå universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; electricity demand; real-time pricing; demand flexibility; elasticity; appliance-level data; end-use; media; contract choice; de-regulated market; household behavior; intermittent electricity production; efficiency; imperfect information;

   Sammanfattning : Paper [I] Using a unique and highly detailed data set on energy consumption at the appliance-level for 200 Swedish households, seemingly unrelated regression (SUR)-based end-use specific load curves are estimated. The estimated load curves are then used to explore possible restrictions on load shifting (e.g. LÄS MER

3. 2. Towards sustainable energy consumption : Electricity demand flexibility and household fuel choice

   Författare :Aemiro Melkamu Daniel; Lars Persson; Runar Brännlund; Rauli Svento; Umeå universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Choice experiment; demand flexibility; electricity contract; fuel choice; fuel stacking; household heterogeneity; load control; pro-environmental framing; willingness-to-accept;

   Sammanfattning : Paper [I] investigates household heterogeneity in valuing electricity contract attributes that include various load controls and information sharing to induce demand flexibility. Using a stated preference choice experiment conducted with Swedish households, this paper shows that, although a large proportion of households ask for substantial compensation, some households are willing to share their electricity consumption information and require relatively lower compensation to allow load controls.

4. 3. Demand Side Response : Exploring How and Why Users Respond to Signals Aimed at Incentivizing a Shift of Electricity Use in Time

   Författare :Isak Öhrlund; Cajsa Bartusch; Peter Juslin; Mikael Larsson; Jacopo Torriti; Uppsala universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Demand response; Electricity use flexibility; Time-varying rate; Dynamic pricing; Price-based program; Time-of-use; Demand charge; Real-time pricing; Real-time feedback; Prosumer; Non-price signal; Non-price incentive; Engineering Science with specialization in industrial engineering and management; Teknisk fysik med inriktning mot industriell teknik;

   Sammanfattning : With increased weather-dependent electricity production and electrification at the heart of the ongoing transition away from fossil fuels, peaks in electricity demand are set to increase and become increasingly difficult to meet, which threatens the functioning of the electric power systems that our society depends on. Time-varying electricity rates, which aim to incentivize electricity users to shift their electricity use in time, have been proposed as a key instrument in alleviating grid imbalances and bottlenecks.

5. 4. Flexibility from local resources: Congestion management in distribution grids and carbon emission reductions

   Författare :Nima Mirzaei Alavijeh; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Flexibility; local energy system; local flexibility market; emission abatement strate- gies; congestion management; distribution system operator;

   Sammanfattning : Flexibility from local energy systems has been discussed as a facilitator for the transition towards a more carbon-neutral energy system. Two use cases of this flexibility are congestion management in electricity distribution networks, and an individual-driven reduction of carbon footprints. LÄS MER

7. 5. Avoiding greenhouse gas emissions using flexibility in smart thermal grids

   Författare :Jay Hennessy; Hailong Li; Justin Chiu; Mälardalens universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; district heating; thermal grids; flexibility; avoided emissions; thermal storage; Energy- and Environmental Engineering; energi- och miljöteknik;

   Sammanfattning : The Paris Agreement on climate change entered into force in 2016 and has been ratified by 193 of the 197 Parties to-date, followed by country targets to cut greenhouse gas emissions, not least through an increasing penetration of renewable energy sources. In its 2021 annual World Energy Outlook, the IEA envisages a Net-Zero Emissions by 2050 scenario (NZE) in which renewables as a percentage of total energy supply increase from around 10% in 2020 to over 65% in 2050 and is reflected by a similar change in the percentage of variable renewables in total generation, thereby increasing the need for system flexibility.
