Abstract

With the development of alternate electrical power system with renewable energy sources, the problem of power abandonment due to the mismatch between the energy generated by renewable energy and variable demand has become increasingly prominent. In order to enhance the power storage performance, this study proposes a novel power system for geologic energy storage, hot dry rock based new power system (HDR-NPS), which uses the fracture network of artificial reservoir as the storage space and compressed CO2 as the energy storage medium to realize the consumption of renewable energy. An underground flow heat transfer model is established to illustrate the flow and heat transfer in geothermal reservoir. The power generation capacity of HDR-NPS and hot dry rock is analyzed and compared from thermodynamics perspectives. The results show that the output power of HDR-NPS is 5-6 times higher than that of hot dry rock power generation on a typical day of system operation. The power generation in the whole life cycle can reach three times of that in hot dry rock. Increasing the heat storage temperature and energy storage pressure has a positive impact on the system production capacity.
