Kinetically limited growth of dendritic tin oxide thin films : a machine learning study beyond the structure zone diagram

Even after fifty years since its introduction, the empirical Thornton’s structure zone diagram remains a valuable tool for predicting thin film microstructure. This diagram is essential for understanding the correlation between synthesis, composition, structure, and physical properties in emerging applications. In this work, we critically appraise this diagram by examining Sn─O thin films grown at

Energy storage in grid optimization

Today energy supply is moving towards more renewable, which brings challenges to the power grid. Intermittent power is difficult to predict and cannot be regulated in the same way as conventional power. If the grid is not dimensioned to handle the power peaks, the intermittent power can cause overload on the grid. Overload causes larger losses, can damage electrical components in the grid and/or a

Energy Communities: a transition towards a more just energy system?

We use energy in almost every aspect of our lives. Yet, often, we do not know the source of electricity that powers our homes or heats our food. In this episode, we explore energy communities as a form of decentralised and democratic energy production. Community energy sees people coming together to take control of their energy needs, by finding alternative ways to organise and govern the energy sWe use energy in almost every aspect of our lives.

Grid Capacity : Challenges and Opportunities

Electric power grids have a limited capacity for safe and reliable transfer of power. Due to the ongoing large-scale expansion of variable renewable energy sources, such as wind and solar, there is a growing need for rapid gridcapacity increase.This thesis explores methods for improving and expanding grid capacity through control of converter-interfaced energy resources, including wind and solar pElectric power grids have a limited capacity for safe and reliable transfer of power.

The Synergy of Natural Resources in Renewable Power Generation - Optimising Operation and Dimension of Grid-connected Wind and Solar Power Plant with Pumped Hydro Energy Storage

Det sker en global energiomställning till förnybara energikällor för att minska koldioxidutsläppen och bekämpa klimatförändringar. I Sverige är det tydligt att andelen vind- och solkraft ökat de senaste åren och denna trend förväntas fortsätta parallellt med det ökade elbehovet. En utmaning med vind- och solkraft är dess intermittenta elproduktion med stora effektvariationer som elnätet behöver kl

Thermal Energy Storage in Sweden and Denmark: Potentials for Technology Transfer

Management of intermittent renewable energy sources (RES) such as wind and solar is a significant issue for countries with interconnected electricity markets. Increasing amounts of electricity from intermittent RES increases the variability of electricity supply, causing electricity prices to become highly sensitive weather conditions. Unpredictable prices have a negative effect on new infrastruct

Energilager och nätförluster - Fallstudie Öland

Expansion och integration av vindkraft i distributionsnäten medför ökad risk för överbelastning av ledningar och nätförluster. För att möjliggöra hög andel vindkraft installerat i distributionsnätet så har E.ON installerat ett Dynamic Line Rating- system på Öland för att övervaka ledningarna och ett styrsystem som kan styra ner elproduktionen från vindkraft då risk för överbelastning förekommer. AThe development of the renewable energy sources and the amount installations in Sweden and also in other countries have increased a lot the last years, this is especially true for solar- and wind power. Main reason for the increase of the renewable energy sources is to decrease the usage of fossil fuels and thus to decrease the impact on the climate. The integration of the renewable energy sources

Thermal Performance Analysis of High Temperature Borehole Thermal Energy Storage Design from an Insulation Perspective

En utvärdering av design- och isoleringsaspekter för högtemperatursvärmelager i berg är en av nycklarna till en mer hållbar framtida energiförsörjning. Men värmelagringsförmåga såväl som ekonomisk potential behöver analyseras. I en värld kämpande mot klimatförändringar, krävs stora kraftsamlingar för att en framtida hållbarhet skall vara uppnåbar. Centralt för detta ligger minskning av koldioxidu

Kapacitetsallokering för batterilager som levererar snabba reserver

Batterilager i elnätet blir vanligare och större, till den grad att det är aktuellt med direk- tanslutning till transmissionsnätet. Som en del av elektrifieringen kan batterier spela en viktig roll för nätets stabilitet − de kan snabbt och exakt leverera mycket effekt, både in i och ut ur nätet. Detta gör dem särskilt lämpade för snabba reserver, såsom FCR-D och FFR. I varje punkt i elnätet finns
