  2. 1. Control Lyapunov Functions : A Control Strategy for Damping of Power Oscillations in Large Power Systems

    Author : Mehrdad Ghandhari; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; UPFC; CSC; QBT; Lyapunov function; Control Lyapunov Function; SIME; Sliding mode; Electric power engineering; Elkraftteknik;

    Abstract : In the present climate of deregulation and privatisation, theutilities are often separated into generation, transmission anddistribution companies so as to help promote economic efficiencyand encourage competition. Also, environmental concerns,right-of-way and cost problems have delayed the construction ofboth generation facilities and new transmission lines while thedemand for electric power has continued to grow, which must bemet by increased loading of available lines.

  4. 2. Modeling of Multi Terminal HVDC Systemsin Power Flow and Optimal Power Flow Formulations

    Author : Mohamadreza Baradar; Mehrdad Ghandhari; Bertil Berggren; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Nowadays, due to lack of a strong interconnection between electric power systems within EU, there is a concern about the restricted power exchange. On the other hand, one of the factors which results in necessity of improving the level of power exchange is development of renewable energy sources such as offshore wind farms. READ MORE

  5. 3. SECURITY OF SUPPLY DURING THE ENERGY TRANSITION:THE ROLE OF CAPACITY MECHANISMS

  6. 4. The Impact of Non-synchronous Generation on Power Systems Dynamics

    Author : Harold Chamorro; Mehrdad Ghandhari; Jonas Persson; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Due to the increasing integration of Renewable Energy Sources (RES), and the installation of High Voltage Direct Current (HVDC) systems, more power is injected to the AC grid based on power electronic converters. This kind of power injection is called non-synchronous generation in this thesis. READ MORE
