Modeling of decoupling concentrated solar power plant

This study investigates a model based on thermodynamic concept to improve the performance of the power block of the concentrated solar power (CSP) systems. The analytical solution of this model established by Aspen HYSYS, Engineering Equation Solver (EES) software programs and Matlab software programming system (Code and Simulink package) to study its performance. The model consists of normal combined cycle (CC), so we studied the efficiency of each component like turbines, compressor, pump, heat exchanger and preheater, at the same time we coupled the CC with storage system to make heat and mechanical stability for the cycle. Decoupled scheme of the power block was developed by adding storage system between the gas cycle and the steam cycle. Then, the performance and the output power of the system were evaluated.
