In the aspect of geothermal power generation, although China actively explores and makes contributions to the field of medium-temperature and low-temperature geothermal power generation, low-parameter heat source power generation is generally low in efficiency, small in installed load and limited in profitability due to the limited grade of geothermal resources.
Solar energy is also a renewable clean energy, and along with the continuous improvement of the photo-thermal power generation technology, the efficiency of the photo-thermal power generation system with high steam parameters is greatly improved. However, solar energy is significantly affected by factors such as time and weather, and although the photo-thermal power station is installed in a large scale, the load fluctuation is significant and the photo-thermal power station cannot continuously operate, so that the load of power grid peak regulation is increased, and light abandon is easily caused. In order to realize continuous operation, some photo-thermal projects adopt gas afterburning or energy storage devices, but the former has high operation cost, and the latter has large investment and unsatisfactory project benefits.
Compared with the characteristics of two clean renewable energy sources of terrestrial heat and solar energy, complementary conditions exist in the aspects of energy grade, space-time distribution rule, power generation utilization scale, energy utilization hours and the like, so that the terrestrial heat and the solar energy are compounded, the advantages of the two clean renewable energy sources can be made up for the deficiencies, and the advantages of the two clean renewable energy sources are exerted to the maximum.
