    In this study, thermodynamic analysis of a hybrid solar steam turbine power plant is done considering utilization of solar energy which is produced by parabolic trough collectors. Firstly, simulation of the fuel oil fired simple power plant is carried out and compared with conceptually designed improved solar hybrid version of the plant. During the design procedure, connections of the plant with the solar field via a heat exchanger, preliminary design of this heat exchanger, selection of the solar fluid and sizing and orientation of the solar field are performed. Different cases using data from one unit of Wassit thermal power plant, Wassit, Iraq including fuel saving and increasing power (power bosting) modes for different times of the year are considered, simulations are carried out with MATLAB SIMULINK and compared with each other in terms of increasing efficiency, saving fuel oil, increasing output electricity, decreasing environmental pollution and use of water. Also, extra energy which can be utilized by the solar collector field is found for all cases and simulation of the solar field is done for different times of the year and compared in terms of useful power output, overall heat loss coefficient, fluid output temperature, glass and absorber temperatures. v One unit of Wassit thermal power plant has output power equal to 330MW, and contains 3 Stages of turbine, a condenser, 4 low pressure closed feedwater heaters, 3 high pressure closed feedwater heaters and an open feedwater heater. MATLAB simulations performed using the real data from the original power plant for different modes showed that the proposed power plant efficiency is increased in both modes for all schemes. The rate of increasing output power for one case and the fuel saving for the other cases suggested that, integrating parabolic trough collectors with existing thermal power plant is more reliable, less expensive, environmentally friendly and uses less water (in the steam cycle) than getting electric power from only fuel oil powered thermal power plant. The value of efficiency increase, fuel savings and power increase are also compared for different months of the year (summer, spring and winter). Lastly, simple economic analysis is done and the levelized cost of energy is found to be equal to 13.9 cent/kWh and this price is competitive compared among prices of electricity produced in both conventional and renewable power plants.
