Description

Technical Field

[0001] The present invention relates to a method and system for optimizing the energy configuration of a steel park with multi-hydrogen coordination considering low carbon, belonging to the technical field of energy optimization of steel industrial parks. Background Art

[0002] The development of the integrated energy system (IES) in the steel industrial park has promoted the efficient use of energy. It couples multiple energy forms such as electricity, heat and hydrogen, and has many benefits such as improving energy efficiency and reducing carbon emissions. The methods for preparing hydrogen in the park include coal-to-hydrogen, natural gas-to-hydrogen, water electrolysis, and industrial by-product gas-to-hydrogen. The produced hydrogen is mainly divided into gray hydrogen, blue hydrogen and green hydrogen. Among them, the coal-to-hydrogen route in the gray hydrogen production link has the lowest cost, but the carbon emissions in the production process are high; blue hydrogen is produced through carbon capture technology or natural gas and industrial by-product gas, and there are small amounts of carbon emissions in the production process; green hydrogen is currently a hot topic in the research of hydrogen-containing IES, and is mainly produced by electrolysis of water from renewable energy sources such as photovoltaics and wind power, and no greenhouse gases such as carbon dioxide are produced during the production process.

[0003] At present, the research on the participation of hydrogen energy in the IES energy optimization configuration and scheduling of steel industrial parks mainly focuses on green hydrogen. The current study introduced the green hydrogen industry chain when constructing the steel industrial park, and analyzed the internal connection and influencing mechanism between the green development of the steel park and the green hydrogen industry chain; on this basis, the configuration scheme of the system under different parameters was obtained, and the feasibility and rationality of the scheme were demonstrated; at the same time, based on hydrogen metallurgical processes such as blast furnace hydrogen injection assisted iron reduction, the low-carbon integrated energy system (LIES) architecture of the steel park was established, which provided strong support for the green development of the industrial park. It can be seen that on the basis of the traditional steel industrial park IES, coupling hydrogen energy can give full play to the complementary role with electric energy and thermal energy, and has a positive role in promoting the consumption of new energy. It is worth noting that the current cost of green hydrogen production is one of the important reasons restricting the development and promotion of hydrogen metallurgical processes. Most of the above studies focus on the production and utilization of a single type of hydrogen energy. However, steel enterprises are both hydrogen-producing enterprises and hydrogen-using units, and there are favorable conditions for the coordinated utilization of multiple hydrogens. At present, few studies have considered the coordinated utilization of multiple hydrogens.

[0004] There are differences in many aspects between different methods of hydrogen production. It is necessary to weigh the cost and emission reduction potential according to the usage environment and scenarios, and optimize the use of hydrogen energy in order to better build LIES.

[0088] Embodiment 1:

[0089] This embodiment provides a method for optimizing the energy configuration of a steel park with multi-hydrogen synergy considering low carbon. On the basis of the comprehensive energy system structure of a steel enterprise with both traditional long and short processes, it introduces green hydrogen produced by electricity and blue hydrogen produced by gas, and proposes a multi-hydrogen synergistically driven steel industrial park energy system architecture. Based on this, a planning model with the minimum carbon emissions and maximum net benefits of the steel industrial park as the objective function is constructed, and a planning model with the entire process of multi-hydrogen production, storage and use as the constraint condition is constructed.

[0090] See also Figure 1 ,The energy optimization configuration method of the steel park specifically includes the following steps:

[0091] S100: Based on the original energy system architecture of the steel industrial park, green hydrogen produced from electricity and blue hydrogen produced from gas are introduced to build a low-carbon integrated energy system architecture for the steel industrial park driven by multiple hydrogen synergies;

[0092] S200, considering the hydrogen production, storage and energy conversion equipment in the low-carbon integrated energy system architecture of the steel industrial park, and building the corresponding equipment model;

[0093] S300, the low-carbon integrated energy system architecture of the steel industrial park driven by multi-hydrogen synergy needs to consider the economic feasibility of planning and construction and the coordination and matching of the new part with the original system and other related issues. Therefore, this embodiment constructs an objective function that considers the maximum benefit and minimum carbon emission of the steel industrial park;

[0094] S400, based on the low-carbon integrated energy system architecture of the steel industrial park and the corresponding equipment model, takes the equipment capacity as the decision variable, and comprehensively considers the energy system planning model driven by multi-hydrogen synergy and with the whole process of hydrogen production, storage and use as the constraint condition, solves the objective function, and obtains the optimal configuration plan of the low-carbon integrated energy system of the steel industrial park.

[0095] In one embodiment, step S100 specifically includes:

[0096] Steel companies require a large amount of energy as input during the production process, mainly including coal, coke and purchased electricity; the energy produced and consumed within the company mainly includes by-product gas, power generation from self-provided power plants and waste heat. The traditional steel production system covers multiple typical processes, including coking, sintering, pelletizing, blast furnace, converter and steel rolling. These processes are closely linked and work together to form a complete chain of steel production. Figure 2 shown.

[0097] In the context of the dual carbon goals, the application of green hydrogen and blue hydrogen is the main development trend. After the introduction of green hydrogen and blue hydrogen, the LIES architecture of the steel industrial park will undergo certain changes, mainly including: adding water electrolysis equipment for the production of green hydrogen, adding natural gas hydrogen production equipment and industrial by-product coal gas hydrogen production equipment for the production of blue hydrogen, adding hydrogen storage tank equipment, and adding hydrogen-blended gas turbine equipment. The architecture is as follows: Figure 3 shown.

[0098] Figure 3 In the park, the equipment will couple multiple energy sources such as electricity, gas, hydrogen and heat to meet the energy demand of the entire production process. Among them, hydrogen energy includes green hydrogen and blue hydrogen, which are used as raw materials for steel production and hydrogen fuel for hydrogen-blended combustion engines in power plants.

[0099] As the most direct sources of electricity in the LIES of the steel industrial park, the power grid, wind power, photovoltaic power and self-generated power plants not only provide stable power support for the production system, but also are an important guarantee for the electrolyzer to achieve hydrogen conversion. When generating electricity in self-generated power plants, they mainly rely on hydrogen-blended natural gas and by-product coal gas as raw materials. The fuel source of the hydrogen-blended gas engine is hydrogen-blended natural gas, which is a cogeneration unit with an adjustable heat-to-electricity ratio and has high operating flexibility and energy utilization efficiency; the by-product coal gas includes coke oven gas, blast furnace gas and converter gas, which are produced by coking, blast furnace and converter processes respectively, among which the resource value of coke oven gas is relatively the highest.

[0100] In addition, green hydrogen in the park is produced by electrolysis of water, and blue hydrogen is mainly produced from natural gas and by-product coal gas. After production, it can not only be supplied to hydrogen metallurgy and hydrogen-blended combustion engines, but also stored in hydrogen storage tanks for subsequent use. When the output of renewable energy is insufficient or the load is heavy, the hydrogen energy in the hydrogen storage tank will be released, thereby effectively balancing energy supply and demand.

[0101] As a preferred implementation of this embodiment, in step S200, the corresponding device model includes:

[0102] Green hydrogen production equipment model from electricity, blue hydrogen production equipment model from natural gas, hydrogen production equipment model from industrial byproduct gas, hydrogen storage tank model, hydrogen metallurgical equipment model, and hydrogen-blended gas turbine equipment model, including:

[0103] The model of green hydrogen production equipment uses hydrogen produced by electrolysis of water for steelmaking, which can reduce carbon emissions per ton of steel by 84%, significantly reducing production carbon emissions. It is specifically expressed by the following formula:

[0104]

[0105] in, The input power for producing hydrogen by electrolysis of water; is the output power of hydrogen production by electrolysis of water; η1 is the electrolysis efficiency of the green hydrogen production equipment; P0 is the unit power consumption of hydrogen production by electrolysis of water; T E is the time for hydrogen production by electrolysis; For the electrolytic cell at T E Green hydrogen production in time;

[0106] Natural gas blue hydrogen equipment model, gas hydrogen equipment uses natural gas to produce blue hydrogen, and the common method is natural gas steam reforming combined hydrogen production, which is specifically expressed by the following formula:

[0107] V t G2H =η2V t G ;

[0108]

[0109] in, is the blue hydrogen production in period t; η2 is the natural gas to hydrogen efficiency; is the gas consumption of producing blue hydrogen from natural gas during period t; is the carbon emission of blue hydrogen produced from natural gas at time t; γ1 is the first carbon adsorption rate; β G2H is the carbon emission coefficient of blue hydrogen produced from natural gas; ρ is the density of hydrogen under standard conditions;

[0110] Industrial by-product gas hydrogen production equipment model, existing data show that 1m 2 Coke oven gas can only generate 1 to 1.5 kW·h, which has a small profit margin. In addition, waste gas will be generated during the power generation process. Therefore, the rational use of coke oven gas has become a new way. It is specifically expressed by the following formula:

[0111] P t C2E =η3V t C2E ;

[0112]

[0113] in, is the coal gas hydrogen production in period t; η3 is the coal gas to hydrogen efficiency; is the gas consumption of coke oven gas power generation during period t; γ2 is the second carbon adsorption rate;

[0114] Hydrogen storage tank model, high-pressure gaseous hydrogen storage tank storage technology is one of the more mature hydrogen storage technologies. Considering that the purity of blue hydrogen is almost the same as that of green hydrogen and they have the same purpose, the green hydrogen and blue hydrogen storage equipment in this article use two hydrogen storage tanks of the same specifications. In the hydrogen storage tank model, the focus is on the change in the total hydrogen volume in the tank, which is specifically expressed by the following formula:

[0115]

[0116] in, It is a collection of nodes of hydrogen energy system; is the total volume of hydrogen in hydrogen storage tank i at time t; is the total volume of hydrogen in hydrogen storage tank i at time t-1; is the volume of hydrogen input into hydrogen storage tank i at time t-1; is the volume of hydrogen output by hydrogen storage tank i at time t-1; Δt is the time step.

[0117] For the hydrogen metallurgy model, hydrogen metallurgy has become the core technology path to promote the low-carbon development of the steel industry. Compared with the traditional blast furnace ironmaking process, hydrogen metallurgy is gradually gaining widespread attention and favor in the industry due to its environmental protection and zero-emission characteristics. The final product of carbon metallurgy is CO2, and carbon emissions cannot be avoided from the production process. The final product of hydrogen metallurgy is H2O, which is not only pollution-free, but can also be reused to achieve true zero-carbon emissions. In addition, hydrogen metallurgy does not have strict requirements for the quality purity of hydrogen. Both blue hydrogen and green hydrogen can be used in the hydrogen metallurgical process.

[0118] The hydrogen-blended gas turbine equipment model is based on the gas turbine and uses the combustion of hydrogen-blended gas to achieve cogeneration of heat and power, thereby improving fuel combustion efficiency and reducing carbon emissions. The hydrogen-blended gas turbine converts energy by consuming hydrogen-blended natural gas, which is specifically expressed by the following formula:

[0119]

[0120] in, is the output of gas turbine a; is the energy conversion efficiency of gas turbine a; is the energy conversion efficiency of the gas turbine when no hydrogen is added; is the volume of natural gas consumed by gas turbine a; is the volume of hydrogen consumed by gas turbine a; T G The time for producing hydrogen for gas turbines; is the volume calorific value of the mixed gas; κ His the hydrogen doping ratio; is the volumetric higher calorific value of hydrogen; It is the volumetric higher calorific value of natural gas.

[0121] In addition, for the formula of hydrogen blending ratio, there is a nonlinear relationship of continuous variable division, which will inevitably affect the solution speed and accuracy of the subsequent planning model. Therefore, it is linearized as:

[0122]

[0123] As a preferred implementation of this embodiment, in step S300, from an investment perspective, the beneficiary of the steel industrial park expects to maximize its return on investment within a specific time period. The planning and configuration of the synergy of green hydrogen and blue hydrogen proposed in this embodiment is mainly to add a hydrogen energy industry chain on the basis of the original renewable energy system including wind power and photovoltaics. The focus is on exploring the net benefits after the introduction of a multi-element hydrogen production system, that is, the objective function is specifically:

[0124] maxF net =F s -C out ;

[0125] Among them, F net is the net benefit of the energy system, F s For energy system benefits, C out spending on energy system carbon;

[0126] Specifically:

[0127]

[0128] Among them, f bem is the present value of the profit of the energy system in the mth year; T Y is the operating life of the energy system; n is the initial investment cost of the energy system; L is the present value of the residual value of the energy system;

[0129] C out =C o S mC ;

[0130] C o is the carbon emissions of the enterprise; S mC is the carbon price in year m.

[0131] Among them, the initial investment of the system is mainly the cost of equipment and system construction, that is, the cost of building the entire industrial chain of multi-hydrogen production, storage and use. Since hydrogen can be directly used in the blast furnace hydrogen injection reduction process, the blast furnace transformation cost is not taken into account, and the calculation is shown in the following formula:

[0132]

[0133] in, is the construction cost of equipment i; E i Refers to the device type, i∈{1,2,…,5}, where E i It represents electric hydrogen production equipment, natural gas hydrogen production equipment, byproduct coal gas hydrogen production equipment, hydrogen storage facilities and hydrogen-blending power generation equipment in turn; f a For additional cost.

[0134] Equipment E i The construction cost is calculated as follows:

[0135]

[0136] Among them, N i is the capacity / number of device i; U i For device E i Unit price.

[0137] The net income of the system is composed of the income from electricity substitution, the income related to hydrogen energy utilization and the income from energy saving, minus the operation and maintenance costs and the cost of purchasing natural gas. The calculation process is shown in the following formula. Among them, the income from electricity substitution is the income from hydrogen-blended gas turbine power generation in the power plant, which is determined by the annual power generation and the comprehensive electricity price. In the steel park, there are some impact load equipment, such as electric arc furnaces and rolling mills. By coordinating the operation of hydrogen-blended gas turbine power generation with these impact loads, the demand electricity charge of the park, that is, the peak value of the electricity load, can be reduced.

[0138]

[0139] Among them, f em is the reduced electricity purchase cost in the mth year; f xm is the annual electricity demand reduction in the mth year; f Hm is the income from the joint substitution of green hydrogen and blue hydrogen in the mth year; f sm is the cost of purchasing hydrogen in the mth year; f ywm is the operation and maintenance cost in the mth year; δ is the depreciation rate.

[0140] The reduced electricity purchase cost in the mth year is composed of hydrogen-blended gas turbines and industrial by-product gas power generation replacing the park's electricity consumption, as shown in the following formula:

[0141] E C1 =P C T C +P C2E T C2E -P GH T GH ;

[0142] f em =E Cl S en ;

[0143] Among them, E C1 is the total local electricity consumption; P C is the capacity of hydrogen-blended fuel engine; T C P is the annual equivalent utilization hours of hydrogen-blended fuel engines; C2E is the coke oven gas power generation capacity; T C2E P is the annual equivalent utilization hours of coke oven gas power generation; GH is the rated capacity of the water electrolysis equipment; T GH is the annual equivalent utilization hours of the water electrolysis equipment; S en It is the local unit electricity cost.

[0144] The demand electricity fee is settled on a monthly basis, and the reduction is due to the impact loads such as the generation of hydrogen-blended gas turbines, electric arc furnaces, and steel rolling, namely:

[0145]

[0146] Among them, P k is the peak load value of the park replaced by hydrogen-blended gas turbine power generation in the kth month. Its monthly value is affected by production planning and scheduling, and its annual value is considered fixed. x It is the demand electricity charge.

[0147] The benefits related to the utilization of hydrogen energy such as polyhydrogen include replacing the original methanol to produce hydrogen, reducing carbon benefits for steel enterprises, reducing the cost of purchasing coal and reducing the cost of purchasing natural gas, as shown in the following formula:

[0148]

[0149]

[0150] Among them, L1 is the carbon reduction per unit of electricity; L2 is the carbon reduction per unit of hydrogen metallurgy; V C2 is the annual amount of hydrogen used for hydrogen metallurgy; L3 is the carbon reduction per unit of hydrogen energy substitution in steel rolling protection gas; V C3 is the annual amount of hydrogen used as steel rolling protection gas; L4 is the carbon reduction per unit of hydrogen energy replacement in hydrogen-blended combustion engines; V C4 is the annual amount of hydrogen used for hydrogen-blended combustion engines; T B1 V is the annual equivalent utilization hours of gas-to-hydrogen equipment; C5 is the annual amount of hydrogen used for hydrogen-blended combustion engines; V0 is the amount of hydrogen consumed in smelting unit mass of molten iron; S mco is the average coal price in the mth year; σ is the amount of coal consumed to smelt a unit mass of molten iron; S mg is the average natural gas price in year m.

[0151] The revenue from hydrogen sales depends on factors such as the hydrogen metallurgical substitution ratio, the hydrogen-blended gas turbine substitution ratio, the amount of self-produced hydrogen and the hydrogen price, and can be calculated as follows:

[0152]

[0153] in, is the self-produced hydrogen volume of the steel industrial park; S H is the purchase / sale price of hydrogen. When the proportion of hydrogen-powered ironmaking and hydrogen-blended gas turbine substitution is low, the hydrogen produced within the park can meet the actual demand, and the cost of purchasing hydrogen in the mth year is negative. At this time, there is sufficient hydrogen and it can be sold, which is classified as hydrogen substitution income.

[0154] The operation and maintenance costs are related to the actual situation. It is difficult to accurately describe the annual value. It can be estimated as follows:

[0155] f ywm =α(f em +f Hm );

[0156] Among them, α is the operation and maintenance cost ratio coefficient.

[0157] In addition, the equipment in the system such as water electrolysis hydrogen production, hydrogen blending gas turbine and hydrogen storage tank can be recycled according to the corresponding depreciation rate after the operation period ends, and there is still residual economic value, that is, residual value, as shown in the following formula:

[0158]

[0159] Among them, LT is the value of the energy system in year T.

[0161] Constraints on hydrogen production from electricity, hydrogen production from gas, hydrogen utilization constraints and hydrogen storage constraints.

[0162] Among them, the constraints of hydrogen production from electricity and hydrogen production from gas are:

[0163] P GH,min ≤P GH ≤β(P S +P W );

[0164] Among them, P GH,min is the minimum installed capacity of the water electrolysis hydrogen production device; β is the maximum proportion of the water electrolysis hydrogen production device capacity to renewable energy power generation; P S is the photovoltaic installed capacity; P W Wind power installed capacity.

[0172]

[0173] Where ρ1 is the hydrogen storage density of the hydrogen storage tank; V m is the volume of the hydrogen storage tank.
