  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.

    Abstract : The electric power systems are currently being transformed through the integration of intermittent renewable energy resources and new types of electric loads. These developments run the risk of increasing mismatches between electricity supply and demand, and may cause non-favorable utilization rates of some power system components. READ MORE

  7. 5. Analysis of Sub-Synchronous Oscillations in Wind Power Plants

    Author : Muhammad Taha Ali; Mehrdad Ghandari; Massimo Bongiorno; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Doubly fed Induction generator; eigenvalue analysis; sub-synchronous control interaction; voltage source converter; Electrical Engineering; Elektro- och systemteknik;

    Abstract : The modern power system is moving towards the high integration of renewable energy sources at a fast pace. The integration of wind power in the power system raises many challenges along with the benefits. One of the recent challenges is the sub-synchronous oscillation (SSO) that occurs in doubly-fed induction generator (DFIG) based wind farms. READ MORE
