Description of the research topic:
a) Preliminaries:
An increasing share of uncontrollable renewables in the electricity production necessitates the load-following operation of other power plants. Also big-sized ones (nuclear and/or biomass based) must be considered, which were traditionally designed and used for base-load operation. Advanced control is necessary for fulfilling this new task. Matured and well-proven methods of the modern control theory should be applied, and this can only be set up based on a deep understanding of the energy engineering processes in question.
b) Aim of research:
To study and describe the dynamical behaviors of the most relevant types of large-sized utility power plants. Further, the most important tasks of the control system should be formulated on a rather general approach, which should consider non-classical targets as well, like thermal stresses and material aging. Based on these, the control tasks should be grouped according to the importances of being realized by advanced (coupled, nonlinear) methods or traditional ones.
c) Tasks, main items, necessary time:
Studying the recent and expected changes in the domestic and continental electricity system, to be followed by studying and modeling the dynamical characteristics of big-sized utility power plants (1 year). The most modern control theory should also be studied – with exclusive respect on the applicability of matured and well-proven methods on the specific tasks outlined above (0.5 year). Overlapped with the previous activities, the most relevant findings should be documented and published. The dynamical model(s) should be integrated with the selected control algorithms (advanced and traditional ones) according to the most effective structure outlined previously (1 year). Publication of the new scientific results (continuously). Writing the Ph.D. thesis (1 year).
d) Required equipment:
Computer and numerical environment for dynamical modeling and simulation (Matlab and Ansys or Comsol), access to the scientific literature are readily available at the department.
e) Expected scientific results:
New structure and method, which allows large-sized power plants to be used in load-following operation, which simultaneously targets high control quality and low lifetime consumption.
