1. Variation management for cost-efficient integration of variable renewable electricity
Sammanfattning : The aim of this work is to improve our understanding of how wind power and solar photovoltaics (PV) can be integrated into the electricity system in a cost-efficient manner. For this, a techno-economic cost-minimising model of the electricity system is used for a set of case studies. LÄS MER
2. Mathematical modelling and methodology for cost optimization of variable renewable electricity integration
Sammanfattning : The global production of electricity contributes significantly to the release of carbon dioxide emissions. Therefore, a transformation of the electricity system is of vital importance in order to restrict global warming. LÄS MER
3. Applicability of thermal energy storage in future district heating system - Design methodologies and performance evaluations
Sammanfattning : District heating (DH) enables efficient and economical utilization of energy resources to satisfy the heat and hot water demands in buildings and is, thereby, well-established in Northern European countries. To achieve the future renewable energy system, the current DH systems are proved to undergo transitions towards the future DH systems, with major characteristics including renewable-based heat sources, low temperature networks, lower heating demands and smart controls.

4. Cost-efficient integration of variable renewable electricity - Variation management and strategic localisation of new demand
Sammanfattning : The aim of this work was to improve our understanding of how wind power and solar photovoltaics (PV) can be integrated into the European electricity system in a cost-efficient manner. For this, a techno-economic, cost-minimising model of the electricity system is refined for a number of case studies. LÄS MER
5. Sustainability of rural energy access in developing countries
Sammanfattning : The importance of access to modern energy has been well understood by governments and donor agencies in many developing countries, and significant effort has been made in recent years to address energy access challenges. However, despite these efforts, the International Energy Agency (IEA) has predicted that the energy access problem will remain unresolved by 2030. LÄS MER
