  1. 1. Steady State Operation and Control of Power Distribution Systems in the Presence of Distributed Generation

    Author : Ferry Viawan; Chalmers University of Technology; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; distance protection; stochastic assessment; voltage dip; line drop compensation; distribution systems; on-load tap changer; overcurrent protection; sensitive equipment; voltage dip immunity; voltage control; short circuit; reactive power control; pilot protection.; protection coordination; protection; Distributed Generation; losses;

    Abstract : In this thesis, the impact of distributed generation (DG) on steady state operation and control of power distribution systems is investigated. Over the last few years, a number of factors have led to an increased interest in DG schemes. DG is gaining more and more attention worldwide as an alternative to large-scale central generating stations. READ MORE

  2. 2. Biodiversity Protection in an Aspiring Carbon-Neutral Society : A Legal Study on the Relationship between Renewable Energy and Biodiversity in a European Union Context

    Author : Melina Malafry; Gabriel Michanek; Maria Pettersson; Uppsala universitet; []
    Keywords : SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; Environmental law; nature protection; renewable energy; biodiversity protection; environmental impact assessment; Miljörätt; Environmental Law;

    Abstract : There is a vision in the EU for a transition to a low carbon society, including a carbon-neutral energy system, containing a high share of renewable energy. However, this vision is not isolated from other political goals, such as halting the loss of biodiversity by 2020. READ MORE

  3. 3. Global Supply Chain Design : Exploring configurational and coordination factors

    Author : Muhammad Abid; Lars Bengtsson; Mandar Dabhilkar; Magnus Wiktorsson; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; Industriell ekonomi och organisation; Industrial Engineering and Management;

    Abstract : This thesis addresses the topic of global supply chain design. One major challenge concerns how to manage the tension between separation and integration pertaining to the localization of business activities. In this regard Ferdows (2008) worked to create two new production network models (rooted production network and footloose production network). READ MORE

  4. 4. Car distribution organization : strategic issues in four configurations

    Abstract : This study is concerned with car distribution organization, a context characterized by overcapacity, intense competition, and manufacturers heavily focusing on brands. In the study, different distribution solutions are investigated through applying a framework of four strategic issues. READ MORE

  5. 5. Coordination of protection system and VSC-HVDC to mitigate cascading failures

    Author : Rujiroj Leelaruji; Lennart Söder; Jianping Wang; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electric power engineering; Elkraftteknik;

    Abstract : The rapid development of the global economics has made power systems allover the world become large-scale interconnected grids. This increases the capabilityof power grids to transfer power over the long distance to serve the desiredpower demand with the minimum cost of operation. READ MORE
