  1. 1. Impact from flexible operation on High Head Francis turbines

    University essay from KTH/Hållfasthetslära (Avd.)

    Author : Andreas Skorpen; [2018]
    Keywords : ;

    Abstract : Today the European energy grid contains more renewable energy sources than ever before, yet there is little to no research on how the increased amount affects the cost structure of the remaining energy sources of the grid. A consequence of phasing more renewable energy sources into the power grid, is a reduction of the overall balancing capacity of the grid. READ MORE

  2. 2. Validation of a vortex panel method for aerodynamics and aero-elasticity of Wind Turbine

    University essay from KTH/Kraft- och värmeteknologi

    Author : Antoine Thibierge; [2018]
    Keywords : ;

    Abstract : Ardema3D is a new type of vortex free model code that can simulate wind turbines. This code has been developed in order to replace the state of the art model, the blade element momentum (BEM). READ MORE

  3. 3. Multi-agent autonomous target tracking using distance-based formations

    University essay from KTH/Reglerteknik

    Author : Rasmus Ringbäck; [2017]
    Keywords : ;

    Abstract : In this thesis, the problem of cooperative control of a system of autonomous agents for targettracking is studied, with special focus on autonomous surface vehicles and minimizing theenergy usage in the system. By separating the control problem into two different parts, weindependently calculate the coordination scheme of the system using virtual agents withsingle integrator dynamics and design the control of the actual agents to follow the virtual.

  4. 4. Robust Optimization in Seasonal Planning of Hydro Power Plants

    University essay from KTH/Optimeringslära och systemteori

    Author : Daniel Risberg; [2015]
    Keywords : Linear decision rules; Hydro power planning; Robust optimization;

    Abstract : Hydro power producers are faced with the task of releasing water from the reservoirs in the right time. To do this there are tools using stochastic optimization that aims at maximizing the income of that producer. The existing methods have a high computing time and grow exponentially with the size of the problem. READ MORE

  5. 5. Numerical and experimental investigation of the effectof geometry modification on the aerodynamic characteristics of a NACA 64(2)-415wing

    University essay from KTH/Numerisk analys, NA

    Author : Pradeep Ramesh; [2013]
    Keywords : ;

    Abstract : The objective of the thesis is to study the effect of the geometry modifications on the aerodynamic characteristics of a standard airfoil (NACA series). The Airfoil was chosen for a high aspect ratio and reynolds number of the range 10⁶ - 10⁷ (realistic conditions for flight and naval applications). READ MORE
