Problems solved by technology
However, renewable energy power generation has intermittent and periodic characteristics, and it is difficult to guarantee a continuous and stable power supply for the grid by relying on renewable energy itself.
In addition, when there is too much renewable energy generation, the grid cannot absorb and store it directly
It can be seen that in the future high-proportion renewable energy power generation system, the problem of "source-grid-load" mismatch will become increasingly prominent and become a bottleneck problem restricting the large-scale and high-efficiency development of renewable energy.

Description
technical field [0001] The invention belongs to the field of energy such as SOFC power generation system operation and solar thermal utilization, in particular to a technology for integrating SOFC power generation system and solar thermal storage system, in particular to an integrated power generation and energy storage system with SOFC as a core component. Background technique [0002] In recent years, my country has accelerated the transformation of its energy structure, vigorously developed wind, solar and other renewable energy power generation, and built a high-proportion renewable energy power generation system. However, renewable energy power generation is intermittent and cyclical, and it is difficult to ensure a continuous and stable power supply to the grid by relying on renewable energy itself. In addition, when there is too much renewable energy generation, the grid cannot absorb and directly store it. It can be seen that in the future high-proportion renewable ...
