A signal analysis toolbox for power system identification in Smart Grids
(Master thesis, 2018)This thesis delves into the two fields of signal analysis and small-signal stability of power systems. Due to the extensive deployment of PMUs in today s Smart Grid, new possibilities arise to assess the small-signal ... -
A Slim Wind Turbine Concept with Low Frequency AC Connection
(Master thesis, 2016)This thesis aims to investigate the feasibility of using a slim wind turbine concept together with a low frequency alternating current (LFAC) transmission system in an offshore wind farm system. By a slim wind turbine ... -
A strategic investment model for multinational transmission expansion planning - Comparing competitive and centrally planned solutions for a North Sea Offshore Grid
(Master thesis, 2018)Proper transmission expansion planning (TEP) is important to create an efficient electricity market that provide both economic and environmental benefits. However, if the expansion planner do not consider how the market ... -
A Substation Level State Estimator for Local Data Processing - Algorithms for Power System Monitoring
(Master thesis, 2017)Modelling power systems with substation details in State Estimation (SE) has several advantages. An increased measurement redundancy is possible, because the measurements can be evaluated individually instead of being ... -
A Wide Area Load Shedding Scheme to Prevent Voltage Instability
(Master thesis, 2016)These days, power systems are operated close to their stability limit, and disturbances such as transmission line contingencies can cause the system to lose stability. If the system loses stability, countermeasures has to ... -
Allocation of Capacity for aFRR Exchange on NordLink
(Master thesis, 2017)A growing share of intermittent power production leads to challenges in power system balancing and requires improvement of system regulation capability. Cross-zonal exchange of balancing services is a step towards harmonized ... -
Analyses of Reserve Procurement Costs Using the EMPS Model - Case Study Norway 2050
(Master thesis, 2017)Europe is moving towards an energy transition including increasing the share of power produced from renewable energy sources and an increase of the CO2 price in order to reduce the climate changes and curtail the damaged ... -
Analysis of a Photovoltaic Power Plant at Evenstad
(Master thesis, 2017)The aim of this master's thesis is to investigate the performance and operation of an existing grid connected PV power plant located at Evenstad in Norway. The PV system has a power rating of 70 kWp and has been operating ... -
Analysis of frequency stability: How wind power and HVDC connections affect the future power system
(Master thesis, 2018)Many modern power systems are facing massive changes. Two of the main development trends are more interconnections between neighboring power systems and significant growth in installed capacity of wind power and other ... -

Analysis of the Norwegian-Swedish Market for Green Certificates Using the EMPS Model
(Master thesis, 2015)Over the last few years it has been important for the European countries to support green energy as a countermeasure against climate changes. Norway and Sweden have chosen to implement a common green certificate market, ... -
Analysis of the Role of Energy Storage in Power Markets with Strategic Players
(Master thesis, 2017)Energy storage has gained increasing popularity in both industry and research during the last decade, due to its valuable flexibility service for power systems. Some claim that energy storage may have a central role in the ... -
Analyzing the Integration of Renewable Energy in Interconnected Power Systems Using a Flow-based Market Model
(Master thesis, 2016)As renewable energy is taking on a more pivotal role in power systems around the world, the implications of this development are all the more significant. The study of these issues requires accurate models with publicly ... -
Application of Monte Carlo Simulation to Power System Adequacy Assessment
(Master thesis, 2018)This thesis examines three Monte Carlo Simulation methods that can be used in power system reliability studies. Through application of the methods to both generation- and composite system adequacy assessment, an understanding ... -
Application of Virtual Synchronous Machines for Integration of Offshore Wind Turbines into the Power System of Offshore Oil and Gas Platforms
(Master thesis, 2016)This thesis addresses the technology known as "Virtual Synchronous Machines" and studies an application where it is used to integrate offshore wind turbines into the power systems of oil and gas platforms. The virtual ... -
Area Based Secondary Frequency Control in the Nordic Power System
(Master thesis, 2016)In order for a power system to function properly, it is necessary that the power production is equal to the power demand at all times. The next day's power balance is scheduled by the transmission system operators (TSO's) ... -
