The PhD thesis focuses on the linear concentrating solar power plant (CSP) ("Heat Transfer Fluid" based) technology with particular attention posed on the transient behavior of the solar field.
In this thesis, we focus on strategies to harvest and control solar and thermal radiation, with the goals (1) to improve power generation efficiency using solar and thermal photovoltaics and (2)
In solar thermal power generation applications, the . 3 temporal offset of the highest daytime and lowest nighttime temperatures and relatively low cooling power density, q'''' inhibits the
Both time-varying solar irradiances and loads are considered in the thesis. All simulations are under the same coding environment on a desktop computer with a system frequency 100 Hz and D = 0.002. The studied stand-alone PV generation system is shown in Fig. 2.1 and a Simulink model of the studied PV generation system is shown in Fig. 2.10.
By adopting characteristics of the superC, an integrated PV generation system is proposed as a new stable PV power generation technique in the thesis. Compared the PV generation system with the integrated PV generation system under the steady state, they have same responses.
When the proposed integrated PV generation system is adopted to generate electricity, the output power of the PV array follows the operating states for solar irradiance S or the load R. In addition, the output power of the proposed integrated PV generation system smoothly varies because of the function of the superC.
In plant without a thermal energy storage (“TES”) the expansion tank is placed in the hot side in order to exploit the thermal capacitance of this component to face changes in impinging solar energy [20-23].
In particular, the physical dimension of each pipe segments (i.e. mass of steel, mass of HTF contained) and the expansion vessel influence the thermal inertia of the solar field that plays a fundamental role in the transient behavior of the whole system.
Case 1: If a PV power source is a large-scale centralized power plant, rstly, the integrated PV generation system is connected in parallel with a suitable superC. Secondly, the integrated PV generation system should also be connected in parallel with a compensatory power source. Finally, they are together connected into the power grid.
