  3. 12. Essays on Purchasing Power Parity, Real Exchange Rate, and Optimum Currency Areas

    Författare :Beatrice Kalinda Mkenda; Göteborgs universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES;

    Sammanfattning : This thesis contains three separate papers. Paper I tests whether the theory of Purchasing Power Parity holds in a selected sample of twenty African countries. The paper employs a panel unit root test to test whether the real exchange rates in the panel are mean reverting or not. The test employed is the Im et al (1997) test. LÄS MER

  4. 13. On Power System Stabilizers: Genetic Algorithm Based Tuning and Economic Worth as Ancillery Services

    Författare :Adrian Andreoiu; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : 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.
