This invention provides a method, production process, and resulting steel for controlling cracks in AH36 ship plate steel billets. The steps include: adding molten iron and a first scrap steel to a converter for smelting, with the final temperature of the converter smelting reaching 1590-1610℃, to obtain molten steel; sending the molten steel to an LF furnace for refining, adding a second scrap steel during the refining process, the amount of the second scrap steel being 10-15% of the weight of the molten steel, to obtain refined molten steel; sending the refined molten steel to a continuous casting machine for casting, with a casting speed of 1.3-1.5 m / min, to obtain a billet; after heating in a heating furnace, the billet is sequentially rough-rolled and finish-rolled, followed by cooling, straightening, and finishing treatment to obtain the AH36 ship plate steel. The control method of this invention is simple and easy to operate. By effectively controlling the content of each element, the generation of cracks is reduced, thereby improving production efficiency and reducing production costs.

This invention discloses a dynamic energy storage regulation system for smart microgrids applicable to new energy power plants, relating to the field of power grid management technology. The invention acquires monitoring information of disturbance events occurring in the target system through a condition monitoring module. A prefetching management module prefetches several monitoring values ​​of each acquisition parameter into a cache according to the prefetching strategy for each acquisition parameter. A data analysis module analyzes the retrieval status of all monitoring values ​​prefetched into the cache for each acquisition parameter during various disturbance events, determining the comprehensive impact of each acquisition parameter under the disturbance event. The prefetching management module adjusts the prefetching frequency of each acquisition parameter's monitoring values ​​accordingly when the next disturbance event occurs. In this way, dynamic adaptation of the prefetching of each acquisition parameter during disturbance events can be achieved, solving the problems of resource waste and insufficient prefetching caused by fixed-frequency prefetching in traditional prefetching methods.
