  2. 16. Security of Electricity Supply in Power Distribution System : Optimization Algorithms for Reliability Centered Distribution System Planning

    Author : Sanja Duvnjak Zarkovic; Patrik Hilber; Ebrahim Shayesteh; George Anders; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical Engineering; Elektro- och systemteknik;

    Abstract : The importance of electricity in everyday life and demands to improve the reliability of distribution systems force utilities to operate and plan their networks in a more secure and economical manner. With higher demands on reliability from both customers and regulators, a big pressure has been put on the security of electricity supply which is considered as a fundamental requirement for modern societies.

  4. 17. Maximizing the integration of wind power in distribution system

    Author : Shemsedin Nursebo; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; distribution system; integration issues of wind power; cost benefit analysis.; frequency of tap change; active management strategies;

    Abstract : The global installed capacity of wind power has shown a significant growth, from just 24 GW in 2001 to 283 GW in 2012. This trend is expected to continue for some years to come. Hence a significant amount of wind power needs to be connected to the electric power system. READ MORE

  5. 18. Numerical Modelling and Statistical Analysis of Ocean Wave Energy Converters and Wave Climates

    Author : Wei Li; Isberg Jan; Jens Peter Kofoed; Uppsala universitet; []
    Keywords : Wave power; Wave energy converter; Gravity-based foundation; Power absorption; Wave spectrum; Linear generator; Frequency domain; Wave climate; Ocean wave modelling; Mixed-distribution model; Bivariate distribution; Archimedean copula;

    Abstract : Ocean wave energy is considered to be one of the important potential renewable energy resources for sustainable development. Various wave energy converter technologies have been proposed to harvest the energy from ocean waves. This thesis is based on the linear generator wave energy converter developed at Uppsala University. READ MORE

  6. 19. Variability and variation management in a renewable electricity system -large-scale wind- and solar power deployment in Europe

    Author : Lina Reichenberg; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; marginal cost of electricity; VRE; variability smoothing; solar power; power systems; renewable energy; wind power; energy systems modelling;

    Abstract : The large-scale deployment of wind and solar power poses challenges to the electricity system by introducing variability on the generation side. To handle these variations, variation management strategies can be employed to ensure that generation meets demand. READ MORE

  7. 20. Some Investigations into the Class of Exponential Power Distributions

    Author : Lukas Arnroth; M. Rauf Ahmad; Patrik Andersson; Matúš Maciak; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Exponential power distribution; Skewed exponential power distribution; linear mixed models; score test; Lp-quantiles; quantile regression; posterior convergence rate; Statistics; Statistik;

    Abstract : In this thesis, methods are developed relating to the exponential power class of distributions.Paper I considers Bayesian linear mixed models where the usual normality assumption is replaced by the multivariate exponential power distribution. Particular focus lies on Bayesian testing of the fixed effects. READ MORE
