2. Concepts for Power System Small Signal Stability Analysis and Feedback Control Design Considering Synchrophasor Measurements
Abstract : In the Nordic power network, the existence of poorly damped low-frequency inter-area oscillations (LFIOs) has long affected stability constraints, and thereby, limited power transfer capacity. Adequate damping of inter-area modes is, thus, necessary to secure system operation and ensure system reliability while increasing power transfers. READ MORE

3. On Power System Stabilizers: Genetic Algorithm Based Tuning and Economic Worth as Ancillery Services
Abstract : The problem of power system stabilizer (PSS) parameter tuning is a complex exercise because of the presence of poorly damped modes of oscillation, and continuous variation in power system operating conditions. In recent years, as a result of the newly deregulated market environment, power systems tend to be operated at reduced security margins, thus making the system more vulnerable to disturbances.

4. Voltage Stabilizers: From Design to Synthesis, Processing and Electrical Characterization
Abstract : Voltage stabilizers are additives capable of inhibiting electrical treeing; a degradation mechanism for insulation materials subjected to strong divergent electric fields. The intended use is in cross-linked polyethylene (XLPE) high voltage power cable insulation where minute defects in the manufacturing process can give rise to the conditions needed for the initiation of treeing, which in the worst case scenario leads to failure of the insulation system with blackouts and expensive repairs as a consequence.

5. Aspects of Wide-Area Damping Control Design using Dominant Path Synchrophasor Signals
Abstract : The presence of inter-area oscillations has long affected stability constraints, and therefore, limited the power transfer capacity of interconnected power systems. Adequate damping of these inter-area oscillations is, thus, necessary to secure system operation and ensure system reliability while increasing power transfers. READ MORE
