Research Theme and Topics
The world around us can be seen as interactive signals and systems. The first step in any research and study is "Modeling". My main area of research is "modeling nonlinear dynamic systems" using analytical and experimental methods (identification). My research activities cover a variety of topics including the followings:

  1. Modeling Nonlinear Systems:
    The goal of this research is to address different modeling approaches for nonlinear systems. The approaches include white-box modeling, using physical laws, then different optimization techniques for parameter estimations. Other approaches called black-box modeling, include wavelet analysis, Volterra series.
  2. Power System Modeling and Identification
    Synchronous generators play a very important role in the stability of the power systems. A proper model for synchronous generators is essential for a valid analysis of stability and dynamic performance of the system. Almost three quarters of a century after the first publications in this area, the subject is still a challenging and attractive research topic.The traditional methods of modeling the synchronous generators are well specified in IEEE Standard 115. These methods assume a known structure for the synchronous machine, using well-established theories like Park’s transformation. They address the problem of finding the parameters of the known structure. Usually the procedures involve difficult and time-consuming tests. These approaches include short-circuit tests, standstill frequency response (SSFR) and open circuit frequency response (OCFR) tests. These tests can mainly be carried out when the machine is not in service. To overcome the shortcomings of the traditional methods, identification methods based on on-line measurements have gained attention during the recent years.

  3. Wind Generation and Control
     As a result of increasing environmental concern, more and more electricity is generated from renewable energy. Wind energy  is one of the fastest growing branches considering the installed power of 25 GW at the end of 2001 and 60 GW at the end of 2005.  Wind energy technology has developed extremely rapidly and many commercial wind turbines now on the market have capacity of 2MW or more. Also the cost of wind-generated electricity has fallen steadily.  A review of wind generation increase at different countries shows by the end of the year 2003, the worldwide installed total wind generation was approximately 37000 MW, an increase of 6000 MW compared to the previous year. With growing size and number of wind generation units, the need for some form of advanced control strategy, which can control such a nonlinear dynamic system can easily be foreseen. Advanced control strategies, such as optimal control, robust control, predictive control, adaptive control, all need a linearized state space model of the study system
