[0053] The coal-fired power generation hydrogen production coupled with gas turbine hydrogen blending system includes a coal-fired generator set, a gas turbine hydrogen blending generator set and a hydrogen production system. The coal-fired generator set uses coal as fuel and is a device that generates electricity by burning coal. The energy generated can be used to connect the electricity to the public power grid to meet the living needs of residents, and is also used to provide electricity to the hydrogen production system to produce hydrogen. The gas turbine hydrogen blending generator set is a power generation device that mixes hydrogen and traditional fuels (such as natural gas) in a gas turbine to convert the chemical energy of hydrogen and traditional fuels into electricity. The electricity generated is used to connect to the public power grid to meet the living needs of residents. The hydrogen production system uses water electrolysis technology to produce hydrogen. The coal-fired power generation hydrogen production coupled with gas turbine hydrogen blending system also includes a hydrogen storage system, which is used to store the hydrogen produced by the hydrogen production system.

[0054] Based on the above situation, the embodiments of the present application provide a hydrogen scheduling method, device, system and computer-readable storage medium.

[0055] In a first aspect, an embodiment of the present application provides a hydrogen scheduling method. Figure 1 is a flow chart of a hydrogen scheduling method according to an exemplary embodiment. Figure 1 As shown, the hydrogen scheduling method includes:

[0056] Step S101, obtaining the clearing power load, the kilowatt-hour cost of the coal-fired power generation unit, the first hydrogen production cost electricity price of the gas turbine hydrogen-blended power generation unit, and the second hydrogen production cost electricity price in the hydrogen market, wherein the first hydrogen production cost electricity price represents the electricity price required to prepare hydrogen with the same calorific value as the natural gas in the gas turbine hydrogen-blended unit, and the second hydrogen production cost electricity price represents the electricity price required to prepare hydrogen in the hydrogen market with the same hydrogen production capacity as the hydrogen production system.

[0057] The coal-fired power generation hydrogen production coupled with gas turbine hydrogen blending system also includes a data acquisition module, a data analysis module, a scheduling module and a monitoring module. The data acquisition module collects the clearing power load. The clearing power load is the total power load that needs to meet the market demand determined by the power market dispatching agency within a certain period of time, that is, the power load required by the market is exactly equal to the power load supplied. According to the clearing power load, the electric energy generated by the coal-fired power generation unit will first meet the clearing power load, and the remaining power load will be provided to the hydrogen production system. The hydrogen production system produces hydrogen according to the power load provided by the coal-fired power generation unit.

[0058] The data acquisition module collects the cleared electricity of coal-fired power generation in each period of the previous day and calculates the cleared electricity load to meet the following configurations:

[0059]

[0060] Among them, M aveF is the clearing load, M Lt is the cleared electricity of coal-fired power generation in each period, and t is the market time interval. Optionally, the market time interval includes 15 minutes, 20 minutes, and 25 minutes.

[0061] According to the clearing power load, the power load of the coal-fired power generation unit used for hydrogen production is determined, and the power load used for hydrogen production meets the following configuration:

[0062] M KH =M maxF -M averF

[0063] Among them, M KH is the electrical load of the coal-fired generator set used to produce hydrogen, M maxF is the maximum electrical load of the coal-fired generator set, M aveF It is to clear the electrical load.

[0064] The data acquisition module collects the standard coal consumption of coal-fired power generation units, the supply price of standard coal, and the proportion of fuel cost in coal-fired power generation units, and calculates the cost per kilowatt-hour of coal-fired power generation units through the data analysis module. The cost per kilowatt-hour satisfies the following formula:

[0065]

[0066] Among them, M DC is the electricity cost, M H is the standard coal consumption of coal-fired power generation units, M J is the supply price of standard coal, B R The proportion of fuel costs in coal-fired power generation units.

[0067] The data acquisition module collects the hydrogen capacity of the hydrogen production system, the life of the hydrogen production system, the water consumption of the hydrogen production system, the local water supply price, the unit hydrogen production power consumption of the hydrogen production system, and the construction cost of the hydrogen production system. The data analysis module calculates the first hydrogen production cost electricity price of the gas turbine hydrogen-blended generator set and the second hydrogen production cost electricity price of the hydrogen market.

[0068] The first hydrogen production cost electricity price of the gas turbine hydrogen-blended power generation unit represents the electricity price required to prepare hydrogen with the same calorific value as the natural gas in the gas turbine hydrogen-blended power generation unit. The first hydrogen production cost electricity price is an indicator to measure whether it is economical for the computer of the coal-fired power generation unit to be used to produce hydrogen, and the produced hydrogen enters the internal combustion engine for hydrogen blending and power generation. In the case that the gas turbine hydrogen-blended power generation unit only consumes natural gas for power generation, the consumed natural gas and the supply price of the consumed natural gas are obtained. According to the heat balance, the supply price of the consumed natural gas is converted into the price of hydrogen with the same calorific value. Then, according to the relationship between the hydrogen production cost and the electricity price, the hydrogen price is mapped to the first hydrogen production cost electricity price.

[0069] The relationship between hydrogen production cost and electricity price reflects the unit hydrogen production cost under different electricity prices. The relationship between hydrogen production cost and electricity price satisfies the following configuration:

[0070]

[0071] Among them, H DC is the unit hydrogen production cost, J C is the construction cost of the hydrogen production system, H R is the hydrogen capacity of the hydrogen production system, S M is the life of the hydrogen production system, S H is the water consumption of the hydrogen production system, S J is the local water supply price, D H is the unit power consumption of hydrogen production system, D J It's the price of electricity.

[0072] The supply price of the consumed natural gas is converted into the price of hydrogen with the same calorific value, and the price of hydrogen satisfies the following formula:

[0073]

[0074] Among them, H JP is the hydrogen price corresponding to the natural gas supply price, J TR is the supply price of natural gas, R T is the lower calorific value of natural gas, R H It is the lower calorific value of hydrogen.

[0075] According to the relationship between the above hydrogen production cost and electricity price, the first hydrogen production cost electricity price of the gas turbine hydrogen-blended generator set is obtained to meet the following configuration:

[0076]

[0077] Among them, D JP is the first hydrogen production cost electricity price, H JP is the hydrogen price corresponding to the natural gas supply price, J C is the construction cost of the hydrogen production system, H R is the hydrogen production capacity of the hydrogen production system, S M is the life of the hydrogen production system, S H is the amount of water consumed by the hydrogen production system, S J is the local water supply price, D H is the unit electricity consumption for hydrogen production,

[0078] The second hydrogen production cost electricity price of the hydrogen market represents the electricity price required for the hydrogen market to produce the same amount of hydrogen as the hydrogen production system. The second hydrogen production cost electricity price is an indicator to measure whether it is economical to use the electricity of coal-fired power generation units to produce hydrogen and sell it to the outside world. The data acquisition module collects the hydrogen price of the local hydrogen market, and obtains the second hydrogen production cost electricity price of the hydrogen market based on the relationship between the above hydrogen production cost and electricity price. The second hydrogen production cost electricity price meets the following configurations:

[0079]

[0080] Among them, D P is the second hydrogen production cost electricity price, H J is the hydrogen price in the hydrogen market, J C is the construction cost of the hydrogen production system, H R is the hydrogen production capacity of the hydrogen production system, S M is the life of the hydrogen production system, S H is the amount of water consumed by the hydrogen production system, S J It is the local water supply price.

[0081] By obtaining the cost per kilowatt-hour, the first hydrogen production cost electricity price and the second hydrogen production cost electricity price, we can better measure the use of electricity generated by coal-fired power generation units for different purposes, and uniformly map the prices spent for different purposes into electricity prices, so that we can compare them with the fluctuating grid-connected electricity prices, thereby guiding the operation of coal-fired power generation units and gas turbine hydrogen-blended units.

[0082] Step S102: If the first hydrogen production cost electricity price and the second hydrogen production cost electricity price are both greater than or equal to the cost per kilowatt-hour, determine the electricity load of the coal-fired power generation unit for hydrogen production according to the clearing electricity load, and determine the hydrogen production capacity of the hydrogen production system according to the electricity load.

[0083] If the first hydrogen production cost electricity price is greater than or equal to the cost per kilowatt-hour, it means that the price of natural gas combustion in the gas turbine hydrogen generator set is greater than the price of hydrogen produced by the hydrogen production system for combustion and power generation in the gas turbine hydrogen generator set. If the second hydrogen production cost electricity price is greater than or equal to the cost per kilowatt-hour, it means that if hydrogen from the hydrogen market is used to generate electricity for the gas turbine hydrogen generator set, the price of hydrogen from the hydrogen market is greater than the price of hydrogen used for combustion and power generation in the gas turbine hydrogen generator set. When the first hydrogen production cost electricity price and the second hydrogen production cost electricity price are both greater than or equal to the cost per kilowatt-hour, the hydrogen produced by the hydrogen production system is used to complete the power generation of the gas turbine hydrogen generator set. Therefore, the hydrogen production system produces hydrogen according to the electrical load provided by the coal-fired generator set. The specific contents include:

[0084] Step S100: Acquire a hydrogen production threshold of the hydrogen production system, and determine an electric load threshold required by the hydrogen production system according to the hydrogen production threshold.

[0085] There is a maximum limit to the hydrogen produced by the hydrogen production system through water electrolysis. The maximum amount of hydrogen that can be produced in the hydrogen production system is obtained, that is, the hydrogen production threshold. Based on the hydrogen production threshold, the electrical load required for the hydrogen production system to produce the maximum amount of hydrogen is obtained, and the electrical load required for producing the maximum amount of hydrogen is used as the electrical load threshold.

[0086] Step S200: If the electric load is greater than the electric load threshold, the coal-fired power generation unit provides power to the hydrogen production system according to the electric load threshold, and the hydrogen production amount of the hydrogen production system is the hydrogen production threshold.

[0087] The electric load provided by the coal-fired generator set to the hydrogen production system is compared with the electric load threshold of the hydrogen production system. If the electric load provided by the coal-fired generator set to the hydrogen production system is greater than or equal to the electric load threshold of the hydrogen production system, the coal-fired generator guarantees the clearing electric load, and the remaining electric load is the electric load threshold of the hydrogen production system, that is, the coal-fired generator set generates electricity according to the sum of the clearing electric load and the electric load threshold of the hydrogen production system, and uses the electric load threshold to produce hydrogen in the hydrogen production system to obtain the hydrogen production threshold. For example, the electric load provided by the coal-fired generator set to the hydrogen production system is M KH, the electric load threshold of the hydrogen production system is (H R ×D H ), if M KH ≥(H R ×D H ), then the coal-fired power generation unit will (H R ×D H ) of electrical load is provided to the hydrogen production system. The hydrogen production system is based on (H R ×D H ) to produce hydrogen, and the amount of hydrogen is the hydrogen production threshold.

[0088] Step S300: If the electric load is less than or equal to the electric load threshold, the coal-fired generator provides the current electric load to the hydrogen production system, and the hydrogen production system obtains hydrogen according to the electric load.

[0089] The electric load provided by the coal-fired generator set to the hydrogen production system is compared with the electric load threshold of the hydrogen production system. If the electric load provided by the coal-fired generator set to the hydrogen production system is less than the electric load threshold of the hydrogen production system, the coal-fired generator set will still provide the current electric load to the hydrogen production system to produce hydrogen. The hydrogen production system produces hydrogen according to the current electric load. For example, the electric load provided by the coal-fired generator set to the hydrogen production system is M KH , the electric load threshold of the hydrogen production system is (H R ×D H ), if M KH <(H R ×D H ), then the coal-fired power generation unit will be M KH The electricity load is provided to the hydrogen production system. KH The electrical load is used to produce hydrogen.

[0090] In addition, the first hydrogen production cost electricity price and the second hydrogen production cost electricity price are both greater than or equal to the cost per kilowatt-hour, indicating that it is more economical to use the hydrogen produced by the hydrogen production system for power generation in the gas turbine hydrogen blending system. Therefore, the power generation of the coal-fired generator set is increased to obtain more electrical load for the hydrogen production system to produce hydrogen.

[0091] If the first hydrogen production cost electricity price and the second hydrogen production cost electricity price are both lower than the cost per kilowatt-hour, it means that the hydrogen production of the hydrogen production system is not economical for use in the gas turbine hydrogen blending system to generate electricity. Therefore, the current power generation of the coal-fired generator set is maintained.

[0092] The coal-fired power generation unit will provide the generated electricity load to the public power grid first to meet the needs of residents' lives, and then use the remaining electricity load to produce hydrogen in the hydrogen production system. If the remaining electricity load is greater than the electricity load threshold of the hydrogen production system, it means that the generated electricity load is too much, and the coal-fired power generation unit will produce according to the clearing electricity load and the electricity load threshold. If the remaining electricity load is less than the electricity load threshold of the hydrogen production system, it means that the current electricity load can both meet the needs of residents' lives and enable the hydrogen production system to work to produce hydrogen, and the coal-fired power generation unit will maintain the current electricity load for production.

[0093] Step S103: If the first hydrogen production cost electricity price is greater than or equal to the cost per kilowatt-hour, and the hydrogen production amount is less than or equal to the hydrogen blending threshold of the gas turbine hydrogen blending generator set, the hydrogen production amount is used for power generation by the gas turbine hydrogen blending generator set.

[0094] The first hydrogen production cost electricity price is greater than or equal to the kilowatt-hour cost, indicating that the price of natural gas combustion in the gas turbine hydrogen generator set is greater than the price of hydrogen produced by the hydrogen production system for combustion and power generation in the gas turbine hydrogen generator set. The hydrogen blending threshold of the gas turbine hydrogen generator set is the maximum amount of hydrogen that can enter the gas turbine hydrogen generator set to replace natural gas for combustion and power generation. The hydrogen produced by the hydrogen production system is all used for combustion and power generation in the gas turbine hydrogen generator set.

[0095] When the first hydrogen production cost price is greater than or equal to the cost per kilowatt-hour and the hydrogen production of the hydrogen production system is less than or equal to the hydrogen blending threshold of the gas turbine hydrogen-blended generator set, the hydrogen produced by the hydrogen production system enters the gas turbine hydrogen-blended generator set for power generation, replacing part of the natural gas combustion, thereby alleviating the problem of insufficient natural gas resource supply. On the other hand, the electricity generated by the gas turbine hydrogen-producing generator set is also connected to the public power grid to meet the electricity load of residents' living needs, further strengthening the guarantee of power supply.

[0096] Step S104: if the hydrogen production amount is greater than the hydrogen blending threshold of the gas turbine hydrogen blending generator set, the hydrogen production amount is used for storage and gas turbine generator set power generation, and when the hydrogen production amount is less than or equal to the hydrogen blending threshold again, the stored hydrogen production amount is used for gas turbine generator set power generation.

[0097] If the first hydrogen production cost electricity price is greater than or equal to the cost per kWh, and the hydrogen production of the hydrogen production system is greater than the hydrogen blending threshold of the gas turbine hydrogen-blending generator set. The hydrogen production of the hydrogen production system is greater than the hydrogen blending threshold, which means that the hydrogen production still has some hydrogen on the premise of meeting the power generation of the hydrogen-producing generator set. The hydrogen production of the hydrogen production system is divided into two branches for processing. The first branch uses the hydrogen production for power generation by the gas turbine hydrogen-blending generator set. The second branch transfers the remaining hydrogen to the hydrogen storage system for storage. For example, the hydrogen blending threshold of the gas turbine hydrogen-producing generator set is V max , the hydrogen production capacity of the hydrogen production system is H L , when V max≤H L , then V in the hydrogen production max The hydrogen produced enters the gas turbine hydrogen-blended generator set for power generation, H L -V max The amount of hydrogen is stored in the hydrogen storage system.

[0098] When the hydrogen production capacity of the hydrogen production system is again less than the hydrogen blending threshold of the gas turbine hydrogen blending generator set, all the hydrogen produced by the hydrogen production system will be used for power generation by the gas turbine hydrogen blending generator set, and the hydrogen in the hydrogen storage system will also enter the gas-fired hydrogen production generator set for power generation, to ensure that the gas turbine hydrogen production generator set can generate electricity with the maximum amount of hydrogen blending, thereby increasing the combustion of hydrogen and reducing the combustion of natural gas, thereby alleviating the problem of natural gas shortage, and at the same time, the electrical load generated by the gas turbine hydrogen blending generator set will be connected to the public power grid to ensure power supply.

[0099] Step S105: If the first hydrogen production cost electricity price is less than the cost per kilowatt-hour, the hydrogen production capacity of the hydrogen production system is sold.

[0100] When the first hydrogen production cost price is less than the kilowatt-hour cost price, it means that the use of gas turbine hydrogen generator sets to generate electricity using natural gas combustion is more economical than the use of hydrogen production system to generate electricity using hydrogen. Therefore, the gas turbine hydrogen generator set uses natural gas combustion to generate electricity, and does not introduce the hydrogen production system.

[0101] The data acquisition module collects the hydrogen demand of the local hydrogen market. If the hydrogen demand of the hydrogen market is greater than or equal to the hydrogen production of the hydrogen production system, the hydrogen production of the hydrogen production system will be sold entirely to obtain economic benefits.

[0102] If the hydrogen demand in the hydrogen market is less than the hydrogen production of the hydrogen production system, it means that the hydrogen market is in a saturated state. Therefore, part of the hydrogen production of the hydrogen production system is used for sale to obtain some economic benefits, and the other part of the hydrogen production is stored in the hydrogen storage system. When the hydrogen demand in the hydrogen market is greater than or equal to the hydrogen production of the hydrogen production system, the stored hydrogen is used for sale.

[0103] The hydrogen produced by the hydrogen production system is sold, which expands the business channels for selling hydrogen to the outside world, thereby improving the flexibility of the coal-fired power generation hydrogen production coupled with the gas turbine hydrogen blending system. The hydrogen produced by the hydrogen production system can be used for power generation by the gas turbine hydrogen blending generator set and can also be sold. Selling hydrogen to the outside world also alleviates the operating pressure of the enterprise and brings economic benefits.

[0104] The monitoring module in the coal-fired power generation hydrogen production coupled gas turbine hydrogen blending system is used to comprehensively monitor the operation of the coal-fired power generation hydrogen production coupled gas turbine hydrogen blending system, and the issued commands are sent to the control module. The control module adjusts the operation of the coal-fired generating set, the hydrogen production system, the gas turbine hydrogen blending generating set and the hydrogen storage system according to the above-mentioned hydrogen scheduling method.

[0105] Figure 2 is a process flow diagram of a coal-fired power generation hydrogen production coupled with a combustion engine hydrogen blending system according to an exemplary embodiment. Figure 2 As shown, the coal-fired power generation hydrogen production coupled with gas turbine hydrogen blending system includes a coal-fired generator set, a water electrolysis hydrogen production system, a gas turbine generator set and a hydrogen storage system. The electricity generated by the coal-fired generator set is used to access the public power grid and is provided to the water electrolysis hydrogen production system so as to prepare hydrogen by the water electrolysis hydrogen production system. The prepared hydrogen is used for hydrogen blending power generation by the gas turbine generator set and storage in the hydrogen storage system. The gas turbine generator set uses hydrogen to generate electricity and connects the generated electricity to the public power grid to ensure power supply. The hydrogen stored in the hydrogen storage system can be used to sell hydrogen to the outside world, and can also provide hydrogen to the gas turbine generator set for hydrogen blending power generation.

[0106] Figure 3 FIG. 1 is a schematic diagram of the internal structure of a coal-fired power generation hydrogen production coupled with a combustion engine hydrogen blending system according to an exemplary embodiment. Figure 3 As shown in the figure, the coal-fired power generation hydrogen production coupled with gas turbine hydrogen blending system includes a data acquisition module, a data analysis module, a scheduling module and a monitoring module. The data acquisition module collects data from the local hydrogen market, the raw material supply market, the electricity day-ahead market, the coal-fired generator set, the hydrogen production system, the hydrogen storage system and the gas turbine generator set. The data analysis module analyzes the collected data and transmits the analysis results to the scheduling module. The scheduling module adjusts the coal-fired generator set, the hydrogen production system, the hydrogen storage system and the gas turbine generator set, and transmits the adjusted content to the monitoring module. The monitoring module monitors the scheduling module according to the adjusted content to avoid errors in the scheduling module.

[0107] Figure 4 is a flow chart of a hydrogen scheduling method according to an exemplary embodiment. Figure 4 As shown, the coal-fired power generation unit generates electricity at an average clearing load and transmits it to the public power grid. Under the premise of meeting the clearing load, if the first hydrogen production cost electricity price is less than the cost per kilowatt-hour or the second hydrogen production cost electricity price is less than the cost per kilowatt-hour, the electric load of the coal-fired power generation unit is all used to access the public power grid and is not used for the hydrogen production system to produce hydrogen. If the first hydrogen production cost electricity price and the second hydrogen production cost electricity price are both greater than the cost per kilowatt-hour, and the electric load provided by the coal-fired power generation unit to the hydrogen production system is greater than or equal to the electric load threshold of the hydrogen production system, the hydrogen production system produces hydrogen according to the maximum electric load threshold. If the electric load provided by the coal-fired power generation unit to the hydrogen production system is less than the electric load threshold of the hydrogen production system, hydrogen is produced according to the electric load provided by the coal-fired power generation unit to the hydrogen production system.

[0108] When the hydrogen production system produces hydrogen according to the electrical load provided by the coal-fired generator set and obtains the hydrogen production volume, if the first hydrogen production cost electricity price is greater than or equal to the cost per kilowatt-hour, and the hydrogen blending threshold of the gas turbine hydrogen blending generator set is greater than or equal to the hydrogen production volume, the hydrogen production volume will be used entirely for gas turbine hydrogen blending power generation. If the hydrogen blending threshold of the gas turbine hydrogen blending generator set is less than the hydrogen production volume, the hydrogen production volume equal to the hydrogen blending threshold will be used for gas turbine hydrogen blending generator set power generation, and the remaining hydrogen production volume will be transmitted to the hydrogen storage system for storage. When the hydrogen blending threshold is greater than the hydrogen production volume again, the hydrogen stored in the hydrogen storage system will be used for gas turbine hydrogen blending generator set power generation.

[0109] If the first hydrogen production cost electricity price is less than the kilowatt-hour cost and the demand in the hydrogen market is greater than or equal to the hydrogen production capacity of the hydrogen production system, all the hydrogen production capacity will be sold to the outside. If the demand in the hydrogen market is less than the hydrogen production capacity of the hydrogen production system, the hydrogen production capacity equal to the demand will be sold to the outside, and the remaining hydrogen production capacity will be transmitted to the hydrogen storage system for storage. When the demand in the hydrogen market is greater than or equal to the hydrogen production capacity again, the stored hydrogen will be sold to the outside.

[0110] In summary, the hydrogen scheduling method provided in the embodiment of the present application, through the coupling between the coal-fired generator set, the hydrogen production system and the gas turbine hydrogen-blended generator set in the coal-fired power generation and hydrogen-blended gas turbine system, determines the hydrogen production amount of the hydrogen production system and the purpose of the hydrogen production amount based on the comparison of the cost per kilowatt-hour, the first hydrogen production cost electricity price and the second hydrogen production cost electricity price. Based on the comparison result, it is determined whether the hydrogen production amount is used for power generation by the gas turbine hydrogen-blended generator set or for selling hydrogen to the outside. If it is used for power generation by the gas turbine hydrogen-blended generator set, the power supply can be further guaranteed by transmitting the obtained electric energy to the public power grid, thereby realizing the efficient use of hydrogen and electric energy. If it is used for external sale, the economic benefit is improved by the hydrogen production amount.
