Description

technical field [0001] The invention relates to the field of comprehensive energy of power systems, in particular to a cooling, heating and power comprehensive energy system considering source-load-storage and an optimized operation method thereof. Background technique [0002] With the rapid development of social economy, the demand for energy from all walks of life is also increasing, so the depletion of energy has become a major problem that cannot be ignored today, followed by environmental pollution and climate change. Variety. Therefore, finding environmentally friendly and efficient energy sources that can replace traditional energy sources has become a top priority, and the use of clean energy sources has emerged as the times require, mainly solar energy and wind energy. [0003] At present, most energy systems operate independently. Such systems not only have low energy efficiency, but also have high operating costs. Therefore, an integrated energy system that can ...

AI Technical Summary

Problems solved by technology

[0003] At present, most energy systems operate independently. Such systems not only have low energy efficiency, but also have high operating costs. Therefore, an integrated energy system that can couple multiple energy sources and realize the complementary advantages of different energy sources has been proposed.
