[0023] At present, the hydrogen production industry is in its initial development stage in China. Regarding the economic calculation of new energy hydrogen production projects, the current method used is to calculate the economic performance of the whole year based on rated load and typical days. The calculation method is simple and extensive, with little basic data and large prediction errors. It cannot reflect real and accurate economic data, resulting in many projects being unable to make decisions or making wrong decisions due to lack of scientific and reliable data, which has affected the development of the hydrogen production industry.

[0024] To solve the above problems, the embodiment of the present invention provides a method for evaluating the economic indicators of a new energy hydrogen production system based on a simulation workstation. By building a new energy hydrogen production system model and performing simulation evaluation with real economic parameters, the accuracy and reliability of the economic data of the new energy hydrogen production project are improved, and the economic indicators to be evaluated provided by the user are accurately evaluated. The scheme of this application will be described and introduced through multiple embodiments below.

[0025] The first embodiment of the present invention relates to an economic indicator evaluation method for a new energy hydrogen production system based on a simulation workstation. Figure 1 As shown in , the method in this embodiment specifically includes the following steps.

[0026] Step 101: Acquire the construction requirements and evaluation requirements input by the user, where the evaluation requirements include economic indicators to be evaluated selected by the user.

[0027] Specifically, the user can input the construction requirements of the new energy hydrogen production system model through the human-computer interaction interface of the simulation workstation. The construction requirements are the demand information input by the user for the new energy hydrogen production system model to be built, which may include the construction expansion model, the specific equipment model required, etc. This application does not impose specific restrictions on this. In addition, the user can also input the evaluation requirements for building a new energy hydrogen production system model through the human-computer interaction interface of the simulation workstation. The evaluation requirements include the economic indicators and economic parameters to be evaluated selected by the user. The economic indicators to be evaluated can be selected by the user, specifically a specific indicator data that the user wants to know, which can be calculated based on the economic parameters combined with the relevant scale information of the new energy hydrogen production system model, such as annual depreciation cost, annual operating cost, annual profit, internal rate of return, investment payback period, etc. This application does not impose specific restrictions on this.

[0028] In one example, before obtaining the building requirements and evaluation requirements input by the user before executing step 101, the method of this implementation further includes: building a simulation model library based on Simulink of MATLAB, and embedding the simulation model library into the Library of Simulink.

[0029] Specifically, MATLAB, which is the abbreviation of "matrix laboratory", means matrix laboratory. It is a programming environment for algorithm development, data analysis, visualization and numerical calculation. Simulink is a visual simulation tool in MATLAB. It is a block diagram design environment based on MATLAB. It is a software package for dynamic system modeling, simulation and analysis. It is widely used in the modeling and simulation of linear systems, nonlinear systems, digital control and digital signal processing. Simulink provides an integrated environment for dynamic system modeling, simulation and comprehensive analysis. It has been widely used in complex simulation and design of control theory and digital signal processing. By building a simulation model library and embedding the simulation model library into the Simulink Library, the simulation model in the simulation model library can be flexibly called.

[0030] In another example, the simulation models in the simulation model library include a plurality of device simulation models and a strategy simulation model;

[0031] Among them, multiple equipment simulation models include at least: wind turbine model, photovoltaic model, energy storage system model, PEM electric hydrogen production model (proton exchange membrane water electrolysis hydrogen production), ALK electric hydrogen production model (alkaline water electrolysis hydrogen production), and power grid model; the strategy simulation model is the EMS strategy model.

[0032] Specifically, the equipment simulation model is a new energy hydrogen production simulation model for hydrogen production, and the strategy simulation model is used to simulate the hydrogen production strategy in the new energy hydrogen production system.

[0033] Step 102: Select a corresponding simulation model from the simulation model library according to the building requirements and build a new energy hydrogen production system model.

[0034] Specifically, after obtaining the user's building requirements, the corresponding simulation model is obtained from the simulation model library according to the user's building requirements to build the new energy hydrogen production system model. The simulation model library pre-stores a series of simulation models related to new energy hydrogen production, which can meet the user's building requirements. The relevant simulation models in the simulation model library can be directly called for building, without the need for complex modeling work, reducing the difficulty of operation.

[0035] In one example, the building requirements include at least: the topological structure and specification information of the new energy hydrogen production system model; in this embodiment, Figure 2 As shown, step 102 of selecting a corresponding simulation model from a simulation model library according to the building requirements to build a new energy hydrogen production system model may include the following steps:

[0036] Step 1021: Determine at least two equipment simulation models and one strategy simulation model required to build a new energy hydrogen production system model according to the topology structure.

[0037] Specifically, the topology structure is the topology structure of the new energy hydrogen production system model that the user wants to build, and the device simulation model and the strategy simulation model included in the new energy hydrogen production system model can be determined according to the topology structure. It should be noted that no matter what kind of new energy hydrogen production system model the user wants to build, the topology structure of the new energy hydrogen production system model must include at least two device simulation model structures and one strategy simulation model structure.

[0038] Step 1022: Select simulation models corresponding to at least two equipment simulation models and one strategy simulation model from a simulation model library to build a new energy hydrogen production system model;

[0039] Specifically, since the simulation models in the simulation model library include multiple device simulation models and one strategy simulation model, after determining at least two device simulation models and one strategy simulation model required to build a new energy hydrogen production system model according to the topological structure, simulation models corresponding to at least two device simulation models and corresponding strategy simulation models can be selected from the multiple device simulation models in the simulation model library. The new energy hydrogen production system model is built by the selected at least two device simulation models and one strategy simulation model.

[0040] Step 1023: Assign parameters to the new energy hydrogen production system model according to the specification information, complete the construction, and obtain the new energy hydrogen production system model.

[0041] Specifically, the specification information includes the type, equipment parameters, simulation step length, acceleration multiple, simulation time, etc. of each device in the new energy hydrogen production system model. The equipment parameters are various parameters required for the simulated hydrogen production work, such as installed capacity, cut-in wind speed, rated wind speed, cut-out wind speed, etc. This application does not impose specific restrictions on the content of the specification information. According to the specification information, the simulation models of each device included in the new energy hydrogen production system model are assigned parameters, thereby completing the parameter assignment of the new energy hydrogen production system model, accurately simulating equipment of specific specifications, completing the construction, and obtaining a constructed new energy hydrogen production system model.

[0042] Step 103: Setting economic parameters for the new energy hydrogen production system model according to the evaluation requirements, running the new energy hydrogen production system model, and recording simulation data during the simulation operation.

[0043] Specifically, since the evaluation requirements include economic parameters given by the user for calculating the economic indicators to be evaluated, the economic parameters can be set for the new energy hydrogen production system model according to the evaluation requirements so as to generate simulation data associated with the economic parameters and the economic indicators to be evaluated during the simulation process. After the economic parameters are set, the new energy hydrogen production system model can be run and the simulation data during the simulation can be recorded.

[0044] In one example, the evaluation requirements obtained in step 101 also include: economic parameters corresponding to each simulation model required to build a new energy hydrogen production system model; on this basis, setting economic parameters for the new energy hydrogen production system model according to the evaluation requirements in step 103 includes: determining the economic parameters corresponding to each simulation model according to the evaluation requirements, and setting corresponding economic parameters for each simulation model in the new energy hydrogen production system model;

[0045] Among them, the economic parameters may include: any one or any combination of hydrogen sales price, investment amount, depreciation period, operation and maintenance cost, and residual value rate.

[0046] Specifically, since the new energy hydrogen production system model contains at least two equipment simulation models, the hydrogen production principle of each equipment simulation model may be different, such as photovoltaic hydrogen production, photovoltaic hydrogen production is to combine solar power generation and water electrolysis hydrogen production into a system, which is regarded as one of the most promising hydrogen production methods, mainly using the direct current generated by the photovoltaic power generation system to directly supply hydrogen production stations for hydrogen production. The working principle of wind turbine hydrogen production is to use a wind turbine to convert wind energy into electrical energy, and then convert electrical energy into hydrogen energy by electrolysis of water. Specifically, the wind turbine converts wind energy into mechanical energy, and then converts mechanical energy into electrical energy through the conversion of the motor, and then produces hydrogen by electrolysis of water. By using the wind turbine energy storage electrolysis hydrogen production device, the purpose of storing wind energy as hydrogen energy can be achieved. It can be seen that different equipment simulation models apply different hydrogen production principles, and the hydrogen production efficiency and hydrogen production cost of different equipment simulation models under the same conditions will also be different, so the hydrogen price, investment amount, depreciation period, and operation and maintenance cost of different equipment simulation models are different. Therefore, the new energy hydrogen production system model contains at least two equipment simulation models that generally have different economic parameters. By obtaining the economic parameters corresponding to each simulation model (equipment simulation model) required to build the new energy hydrogen production system model, the economic parameters of the overall new energy hydrogen production system model can be determined.

[0047] In another example, the evaluation requirements obtained in step 101 also include: a hydrogen production strategy specified by a user; on this basis, operating the new energy hydrogen production system model in step 103 includes: determining the hydrogen production strategy according to the evaluation requirements; operating the new energy hydrogen production system model for simulation with the hydrogen production strategy, wherein the hydrogen production strategy is simulated by the strategy simulation model.

[0048] Among them, the hydrogen production strategy is any one of the following strategies: grid-connected first and then hydrogen production strategy, hydrogen production first and then grid-connected strategy, and off-grid hydrogen production strategy.

[0049] Specifically, during the simulation operation of the new energy hydrogen production system model, different hydrogen production strategies directly affect the cost and efficiency of hydrogen production. For example, off-grid hydrogen production is to provide the electricity generated by wind and solar power generators directly to the electrolyzer system for hydrogen production without passing through the power grid. It is suitable for remote areas or places that cannot access the traditional power grid. Off-grid hydrogen production can obtain lower electricity prices, significantly reduce hydrogen production costs, and have higher system efficiency. Therefore, users can choose a hydrogen production strategy according to their own project needs, and the new energy hydrogen production system model will simulate with this hydrogen production strategy during the simulation process.

[0050] In another example, before running the new energy hydrogen production system model in step 103, the steps also include: acquiring resource data, and importing the resource data into the new energy hydrogen production system model; running the new energy hydrogen production system model for simulation based on the resource data; wherein the resource data is meteorological resource data related to new energy hydrogen production.

[0051] Specifically, resource data refers to meteorological resource data related to new energy hydrogen production collected at the proposed project site, including temperature, light intensity, wind speed and other data related to new energy power generation, simulating real wind and solar power generation. The data granularity is minute-level, and the data length is 8760 hours per year. Compared with the traditional method of estimating annual economic data based on typical days, it is more accurate. Import resource data into the new energy hydrogen production system model; use resource data as the data basis to run the new energy hydrogen production system model for simulation.

[0052] Step 104: After the simulation is completed, the evaluation result corresponding to the economic indicator to be evaluated is calculated based on the recorded simulation data.

[0053] Specifically, since the relevant simulation data is recorded throughout the simulation process, after the simulation run is completed, the evaluation results corresponding to the economic indicators to be evaluated can be calculated based on the recorded simulation data. Among them, the simulation data may include: any one or any combination of power generation, hydrogen production, power purchase, grid-connected power, power purchase price, grid-connected price. Based on the simulation data and economic parameters, the results corresponding to the economic indicators to be evaluated can be calculated.

[0054] In order to facilitate a better understanding of the solution of the present application, the solution is now described with examples.

[0055] Taking an offshore wind power hydrogen production project as an example, the new energy hydrogen production system that the user intends to build includes three equipment: wind power, energy storage, and electric hydrogen production. The economic indicator to be evaluated is: internal rate of return. The user enters the corresponding construction requirements and evaluation requirements into the simulation workstation to start the evaluation. First, according to the user's construction requirements, three equipment simulation models, namely the wind turbine model, energy storage system model, and ALK electric hydrogen production model, and the EMS strategy model are selected from the simulation model library. According to the construction requirements and evaluation requirements entered by the user, the operation strategy is determined to be off-grid hydrogen production, the fixed asset depreciation period is 15 years, and the residual value rate is 5%.

[0056] Accordingly, the specification information and economic parameters are determined according to the construction requirements and evaluation requirements as follows:

[0057] The wind turbine model parameters are: rated installed capacity 100MW, investment 1.4 billion yuan, cut-in wind speed 3m / s, rated wind speed 9m / s, cut-out wind speed 25m / s, operation and maintenance cost 0.05 yuan / kWh;

[0058] The parameters of the energy storage model are: rated installed capacity 200MW, rated charge and discharge power 80MW, maximum SOC 90%, minimum SOC 30%, initial SOC 30%, investment 600 million yuan, operation and maintenance cost 0.05 yuan / kWh;

[0059] The electric hydrogen production model is as follows: the installed capacity of the ALK water electrolysis hydrogen production device is 60MW, the lower limit of the working range is 30%, the upper limit of the working range is 100%, the investment is 3.0 billion yuan, and the operation and maintenance cost is 0.08 yuan / Nm 3 , the price of hydrogen is 32 yuan / Nm 3 .

[0060] After the simulation runs, the following simulation data is recorded:

[0061] The annual power generation of the wind turbine is 200 million kWh, the maintenance cost is 10 million yuan, the energy storage charging and discharging capacity is 24 million kWh, the maintenance cost is 1.2 million yuan, and the hydrogen production capacity of the electric hydrogen production equipment is 35.29 million Nm 3 , maintenance costs are 2.82 million yuan, and hydrogen sales revenue is 1.13 billion yuan. The total investment is 5.0 billion yuan, the total revenue is 1.13 billion yuan, the annual depreciation cost is 320 million yuan, and the annual net profit is 790 million yuan. According to the annual net profit, total investment, and fixed asset depreciation period, the internal rate of return is 15.7%, and the investment payback period is 6.7 years.

[0062] Compared with related technologies, this solution builds a new energy hydrogen production system model by obtaining the user's construction needs and evaluation needs and selecting the corresponding simulation model from the simulation model library; setting economic parameters for the new energy hydrogen production system model according to the evaluation needs, running the new energy hydrogen production system model, and recording the simulation data during the simulation operation; after the simulation operation is completed, the evaluation results corresponding to the economic indicators to be evaluated are calculated based on the recorded simulation data. Through simulation models that can reflect the partial load operation characteristics and economic parameters in the real market, accurate economic data on the economic efficiency of the new energy hydrogen production project is obtained, and relevant calculations are performed on the economic data to obtain results corresponding to the economic indicators that users want to know, providing reliable data support for project decision-making.

[0067] The evaluation module is used to calculate the evaluation result corresponding to the economic indicator to be evaluated based on the recorded simulation data after the simulation operation is completed.

[0068] Specifically, the human-computer interaction module in this embodiment is used to provide a human-computer interaction interface for users to interact with the simulation workstation. The human-computer interaction module may include two parts: input or selection of building requirements and evaluation requirements. Users can exchange data with the simulation workstation through the human-computer interaction module.
