Sensitivity Analysis and Comparison between 25 kW Parabolic Dish System
Abstract: Dish-Stirling
concentrating solar power systems is an efficient and reliable source of
renewable energy. In this paper, the proposed model showed the idea of
Parabolic Dish (PD) systems with control system model which vary the amount of
working gas in the Stirling engine. The control systems were designed using
Matlab /Simulink 2012a. Based on the developed linearized model, an improved temperature
controller with transient droop characteristic and Mean Pressure Control (MPC)
has been proposed. This temperature controller was effective in reducing the
temperature and improving performance of the PD system. The overall performance
of the system improved more than 78% in output power and energy. Besides, the
system improved in term of sensitivity compared with the PD system without
compensated. In addition, thermal losses decreased to 97.6% which is directly
have significant improvement for the output efficiency to the system. The
analysis shows that the PD system is feasible in term of technical but not
economically feasible in the Malaysia environment.
