TECHNO-ECONOMIC ANALYSIS OF 1 MWE SOLAR POWER PLANT USING COMBINED RANKINE CYCLE IN IZMIR, TURKEY

Turkey is one of the middle east countries bene fiting from good irradiation compared to west Europe an countries. According to recent development in solar energy policies in the countries, solar thermal and other solar Technologies can be an attractive solution for the industrial market. To meet some needs in manufacturing processes, textile and food transformations. CSP Technologies as a central receiver (CR) and parabolic trough collector (PTC) have already experimented in turkey  for these purposes. The present work is illustrated as a synopsis of techno-economic and optimization analysis of a small PTC-CSP  system arrangement using a combined Rankine cycle for electricity production in Izmir. This study carries out a comparative cost of optimization  work per kW. Thus, the improvement of the plant assessment study has considered, technical, thermodynamical and economical parametric to highlight the most important factors in the choice of the components that constitute the technology and the arrangement of the modules on the solar field. T he System Advisor Model ( SAM), Meteonorm7 file, and Excel simulation programs have been used to determine some economic parametric such as the Levelized cost of electricity ( LCOE ), internal rate return, net present value and the payback period. The results shown that for a 1MWe solar PTC power plant in Izmir, the initial investment cost is approximately 3.9 Million US Dollar, with  an estimated LCOE of 13.5 USCent Dollar and an Annual Operation Expenditure of 37.5 USDollar /MWh. Moreover, the Required Cost for Optimization per kW h (RCO) of exergy destroyed and energy loss of configuration#1 were found to be 1830.2 and 1887.5 US Dollar showing that it is possible for improvement works to be achieved. The values corresponding to the optimization of the solar field configuration #3 and #2  are close to the minimal required  Cost for Optimization per kW th (RCO) .  This means that no further improvement can be achieved. Due to some constraints faced during this study, it can be better to arrange the solar thermal power plant following the solar multiple (SM) and the installed cost per kW.
