METHOD AND SYSTEM FOR OPTIMIZING OPERATION OF INDUSTRIAL STEAM POWER PLANT COUPLED WITH MOLTEN SALT HEAT STORAGE

Document Type and Number:

WIPO Patent Application WO/2023/274239

Kind Code:

A1

Abstract:

The present disclosure discloses a method and system for optimizing the operation of an industrial steam power plant coupled with molten salt heat storage. Taking the lowest standard coal consumption as an objective function, the steam supply load distribution between the industrial steam power plant and a molten salt heat storage system is changed, and a comparison with the standard coal consumption under a benchmark condition is made. If not less than the standard coal consumption, the original benchmark condition is still the benchmark. If less than the standard coal consumption, a new condition is used as a benchmark comparison condition, and a next iteration is performed. The method for optimizing the operation of the industrial steam power plant coupled with molten salt heat storage proposed in the present disclosure conforms to actual engineering sites, is suitable for an industrial steam power plant to optimize the distribution of steam supply load under the conditions of satisfying dual-variable scheduling constraints of electricity and heat, improves the overall operating energy efficiency, and has broad application prospects.
