  1. 1. Adaptation of Solar Energy Driven Absorption Chillers for Air Conditioning in Commercial Building

    University essay from Högskolan i Gävle/Avdelningen för bygg- energi- och miljöteknik

    Author : Ranjith Shantha De Silva Kalinga; [2017]
    Keywords : ;

    Abstract : The most recent analysis of energy usage in the country reveled that nearly 50% of the power generation is used for air conditioning and mechanical ventilation most of which is used by commercial organizations. The grid generation mix that contains a high percentage of fossil fuel makes such energy usage environment unfriendly. READ MORE

  2. 2. Future frequency control services in the Nordic power system

    University essay from

    Author : Helena Olsson; [2017]
    Keywords : ;

    Abstract : An increased share of electricity production from variable energy sources, especially wind and solar power, and loss of inertia in the system, result in higher demands of frequency control. In the last decades, the quality of the grid frequency in the Nordic power system has gradually deteriorated. READ MORE

  3. 3. Constrained Low-Thrust Satellite Formation-Flying Using Relative Orbit Elements : Autonomous Guidance and Control for the NetSat Satellite Formation-Flying Mission

    University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Author : Lukas Steindorf; [2017]
    Keywords : satellite; formation; control; guidance; continuous; low-thrust;

    Abstract : This thesis proposes a continuous low-thrust guidance and control strategy for satellite formation-flying. Stabilizing feedback based on mean relative orbit elements and Lyapunov theory is used. A novel feedback gain matrix inspired by the fuel-optimal impulsive solution is designed to achieve near-optimal fuel consumption. READ MORE
