    Instantaneous performance of the first integrated solar combined cycle system in Algeria
    (Elsevier, 2011) Behar, Omar; Mohamedi, Kamal; Kellaf, Abdallah; Belhamel, Maiouf
    There is a great interest in the development of renewable energies and more particularly in solar energy. This study arises in midst of construction of the first integrated solar combined cycle system (ISCCS) in Algeria. In the present work, an integrated plant with simple pressure level is proposed and the preferred method for converting solar energy into electricity is applied. Thermal efficiency, electricity production and net solar electricity are the main parameters to evaluate the instantaneous performance of each component of the solar power station through a year. The simulation results show that the power plant can provide about 134MW with efficiency equals 57.5% at night. At daytime, the net solar electricity ratio can be very interested and reach the limit of 15% at the design point. As a result, the output from and the efficiency of the ISCCS will be above the combined cycle regime by 17 and 16.5%, which are correspond to 157MW and 67%, respectively. Increasing of steam turbine capacity by 50% at the design point is other advantage of the proposed design

    Scaling up solar hybrid gas turbine electric power system : simulation and results
    (2012) Behar, Omar; Khellaf, Abdallah; Mohamedi, Kamal
    Scaling up Concentrating Solar Power(CSP)to larger power block sizesis an essential step to reduce unit investment cost, O&M costs, and increases performance. In the present paper a larger solar hybrid gas turbineof 50 MWis investigated wherebyannualperformances of different parts are estimated using a mathematical programimplanted in Visual Fortran 6.0. The selected location for the study is Hassi R’mel where the first solar power plant in Algeria has been built.The simulationresults show that thesolarhybrid gas turbineefficiency of up to 32% is possible, amongst the highest conversion efficiencies for the hybrid system. However, solar electricity ratioup to 85% are feasible; this leads to significant reductions in fuel consumptionof 2000 T/ year. This is the key motivation to follow this concept, although the technical integration of the receiver into the gasturbine is rather complex
