1. Energy Savings Using a Direct Current Distribution Network in a PV and Battery Equipped Residential Building
Sammanfattning : Energy from solar photovoltaic (PV) are generated as direct current (DC) and almost all of today’s electrical loads in residential buildings, household appliances and HVAC system (Heating Ventilation and Air-conditioning) are operated on DC. For a conventional alternating current (AC) distribution system this requires the need for multiple conversion steps before the final user-stage. LÄS MER
2. Modeling Complex Engines as Dynamic Powertrain Members
Sammanfattning : Engine modeling and simulation have been necessary tools for efficient product development in the automotive industry for some time. The scope of this work is novel engine models, tools, and methods for powertrain research and development. LÄS MER
3. Combined heat and power plant flexibility - Technical and economic potential and system interaction
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. Combined Assessment of Future Heat Supply and Demand - A Dynamic Systems Approach
Sammanfattning : In order to meet climate change mitigation targets, the use of fossil fuels has to be reduced and, eventually, be phased out in all sectors. As the heating sector occupies a central place in energy systems, especially in Nordic countries, it is affected by and affects other energy sectors. LÄS MER
5. Technical and Economic Conditions for Efficient Implementation of CO2 Capture - process design and operational strategies for power generation and process industries
Sammanfattning : 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. LÄS MER
