1. Benefits of Coordinating Plug-In Electric Vehicles in Electric Power Systems : Through Market Prices and Use-of-System Network Charges
Sammanfattning : Both electric power systems and the transportation sector are essential constituents to modern life, enhancing social welfare, enabling economic prosperity and ultimately providing well-being to the people. However, to mitigate adverse climatological effects of emitting greenhouse gases, a rigorous de-carbonization of both industries has been set on the political agenda in many parts of the world.

2. Modeling and Forecasting of Electric Vehicle Charging, Solar Power Production, and Residential Load : Perspectives into the Future Urban and Rural Energy Systems
Sammanfattning : The urban and rural energy systems are undergoing modernization. This modernization is motivated by the need to increase sustainability in both systems. Some characteristics of this modernization include electrification of industries, transports, and heating and cooling loads. LÄS MER
3. Some Control Applications in Electric Power Systems
Sammanfattning : This thesis presents some control applications in electric power systems. The work consists of the four parts: interaction between DC cables and ship steering autopilots; frequency estimation; computer relaying; field tests using load switching to damp power oscillations. LÄS MER
4. Control of Systems with Limited Capacity
Sammanfattning : Virtually all real life systems are such that they present some kind of limitation on one or many of its variables, physical quantities. These systems are designated in this thesis as systems with limited capacity. This work is treating control related problems of a subclass of such systems, where the limitation is a critical factor.

5. Demand Flexibility for the Simultaneous Provision of Multiple Services : Tapping the Potential of Controllable Electric Loads for Frequency Reserves and Energy Arbitrage
Sammanfattning : Power systems with increasing shares of renewable energy sources require sufficient flexibility sources. One source of flexibility for future power systems is constituted by flexible electric loads. The concept of demand response captures the utilization of demand side flexibility to provide services to the power system. LÄS MER
