According to the methods of focusing,the solar thermal generation can be classified to tower system,parabolic trough system and dish-stirling system. The parabolic solar thermal generation system is an important type of solar thermal utilization. Compared to tower and dish-stirling system,the parabolic trough system has many advantages such as the small concentration ratio,the simple process,the low material requirement and the simple tracking device because of many concentrator on-axis tracking. The parabolic trough system is the lowest cost, least close to commercialization,larger potential system optimization,and the most suitable to large operation in this three thermal generation systems [1,. The parabolic trough system is composed of concentrator and receiver,and the receiver is the key component that uses solar energy to heat working fluids in receiver. Therefore,the key problem is how to make the solar energy transfer to subsequent generation system efficiently and stably.

In the smart grid context, the article combines SEGS-VI solar thermal power station parameters to establish a solar thermal power generation system model. The thesis is based on the First and Second laws of thermodynamics. It uses the white box model analysis method of the energy system to calculate the solar thermal power generation system-concentrating and collecting subsystem, heat exchange subsystem, and power subsystem to obtain the subsystems dissipation of each process. Finally, the article uses the white box model analysis of the total energy system to treat the subsystems as white boxes, and connects them to form a white box network, makes a reasonable evaluation of the energy consumption status of the total energy system, and finds the weak links in the energy use process of the system. Provide a basis for system energy saving.

In this paper, NSGA-Ⅱ is used to realize the dual-objective optimization and three-objective optimization of the solar-thermal photovoltaic hybrid power generation system; Compared with the optimal solution set of three-objective optimization, optimization based on technical and economic evaluation indicators belongs to the category of multi-objective optimization. It can be considered that NSGA-Ⅱ is very suitable for multi-objective optimization of solar-thermal photovoltaic hybrid power generation system and other similar multi-objective optimization problems.

A solar thermal organic Rankine cycle (ORC) power generation system model established using R245fa as the working fluid and coupled with a solar photovoltaic generator is introduced. Thermal efficiency and exergy efficiency of the model both with and without a heat regenerator are calculated and compared. Results show the solar organic Rankine cycle system with a heat regenerator has higher thermal and exergy efficiency than the system without a heat regenerator, providing better performance in practice. This result provides a basis for further application and improvement of solar photovoltaic and the solar thermal organic Rankine cycle.
