heal.abstract
This dissertation was written as a part of the MSc in Energy Systems at the International
Hellenic University. Its scope is to review researching efforts in the field of Concentrating
Solar Power Plants (CSPP) modeling and to apply appropriately wellestablished
related modeling principles into a 20 MW hybrid parabolic trough CSPP.
For this reason the introductory section documents the importance of appropriate
modeling of CSPP by examining the ground of RES promotion, distinguishing the prospects
of CSPPs and illustrating the parties that would be interested in such a research.
This document goes on with the review of 3 major dilemmas faced by someone who
aims at estimating the production of a CSPP: a) acknowledgment of uncertainty inherent
in these systems, b) building a custom-made model to evaluate the appropriateness
of available modeling tools and c) using commercial integrated CSPP modeling software.
Information provided in that section is being matched with illustrated needs, restrictions
and specificities related to input data required in the modeling process of a
hybrid parabolic trough CSPP with thermal storage. This correlation made the use of
System Advisor Model seem as the most appropriate tool in order that a 20 MW plant to
be modeled. Parametric, statistical and financial analysis is also performed supporting
the exportation of useful conclusions.
Although simulating the operation of a CSPP is a highly demanding process requiring
extensive knowledge of several scientific fields (physics, mathematics, electrical
and mechanical engineering, informatics), sincere support and scientific guidance provided
by Dr. George Giannakides have been proven to be enough for the successful
completion of this study. Acknowledging his contribution and deeply thanking him for
this is the least that I could do.
