Description

technical field [0001] The invention relates to the field of iron and steel smelting, in particular to a device system and method based on multi-energy storage in the iron and steel industry. Background technique [0002] The iron and steel industry is a process production industry, and its production process has the characteristics of continuous production, high power load, large fluctuations, associated gas and waste heat, as well as high energy consumption and large carbon emissions. To reduce carbon emissions, iron and steel enterprises need to make full use of their geographical conditions and their own regional conditions. On the one hand, they use waste heat and energy to generate electricity; on the other hand, they introduce new energy to generate electricity. [0003] The waste heat and waste energy power generation within the enterprise is usually associated with the production process and is an uninterrupted form of power generation. At present, there are two ma...

Problems solved by technology

Photovoltaic power generation not only has obvious discontinuity, but also generates a large amount of power. Once the power generation exceeds the demand for electricity, it is easy to abandon light, resulting in waste of resources. At night and when the light is not strong, it will be necessary to purchase electricity from outside to use electricity for enterprises. make adjustments

[0005] CN114069675A discloses a control system for electric load balance in iron and steel enterprises. The system is controlled by self-contained power plants, public power grids, load sides, energy management systems, energy storage units, resistors and battery management systems, etc., but the system can only The power is effectively distributed through energy management to balance the load, and the source of power cannot be fully provided from the power supply side, and the cost is relatively high

[0006] CN104035475B discloses an active power automatic control method of a photovoltaic power station that takes into account the safety of the power grid and the minimum light curtailment. The method takes the minimum light curtailment and the minimum active load rate deviation of each photovoltaic power plant as the dual objectives, constructs a quadratic programming problem, and uses the interior point method Efficient solution, under the premise of ensuring the safety of the power grid, give priority to the use of photovoltaic resources, taking into account the fair scheduling of photovoltaic power plants, but the method is not suitable for production in the steel industry, and there is still a lot of waste of photovoltaic power
