[0002] The wind-solar coupled hydrogen production system is an advanced energy system that combines a renewable energy power generation system with a hydrogen production system. Due to the unstable characteristics of wind and solar output, for photovoltaic power generation systems, there is sufficient sunlight during the day to provide electricity for the hydrogen production system, but there is no sunlight at night and it cannot provide electricity for the hydrogen production system. For wind power generation systems, electricity can be provided to the hydrogen production system both during the day and at night. The combination of the two can reduce the proportion of power outages in the grid and stabilize system operation. Different wind-solar ratios have a great impact on the entire hydrogen production system. The selection of a reasonable wind-solar ratio scheme plays a key role in the entire wind-solar coupled hydrogen production system.

[0032] Further, the difference coefficient of the evaluation index is calculated based on the standardized evaluation matrix, and the weight of each evaluation index is calculated based on the difference coefficient. The difference coefficient can reflect the uncertainty and information content of each evaluation index, and then the weight of each evaluation index is calculated based on the uncertainty and information content of each evaluation index. The weight of each evaluation index is used to indicate the importance of each evaluation index for evaluating the coupled hydrogen production system.

The wind-solar ratio in the target wind-solar ratio coupled hydrogen production system is the optimal wind-solar ratio.

[0034] In the method for determining the wind-solar ratio of a coupled hydrogen production system provided by the present invention, the original data of the evaluation indicators of the coupled hydrogen production systems with different wind-solar ratios are obtained, and a standardized evaluation matrix and a decision matrix are constructed based on the original data, and then the difference coefficients of the evaluation indicators are calculated based on the standardized evaluation matrix, and the weights of each evaluation indicator are calculated based on the difference coefficients, and a weighted decision matrix is ​​calculated based on the weights, and the positive ideal solution and the negative ideal solution of the coupled hydrogen production systems with different wind-solar ratios are calculated based on the weighted decision matrix, and the target wind-solar ratio coupled hydrogen production system is determined based on the positive ideal solution and the negative ideal solution, which takes into account multiple indicators of the coupled hydrogen production systems with different wind-solar ratios, and can automatically give the optimal wind-solar ratio coupled hydrogen production scheme, thereby resolving the contradiction between the volatility of wind-solar renewable energy and the stability requirements of the chemical process, and ensuring the stable production of hydrogen under the condition of fluctuations in wind-solar renewable energy.

[0035] In a possible implementation of the present invention, raw data of evaluation indicators of hydrogen production systems coupled with different wind-solar ratios are obtained, and a standardized evaluation matrix and a decision matrix are constructed based on the raw data, including: The original data matrix is ​​constructed based on the original data of the number of hydrogen production systems coupled with different wind-solar ratios and the evaluation indicators of each wind-solar ratio coupled hydrogen production system. ,in, Indicates i The first wind-solar ratio coupled hydrogen production system j The original data of the evaluation indicators, m Indicates that there is m Different wind and solar ratios coupled with hydrogen production systems, n Indicates that each wind-solar ratio coupled hydrogen production system has n evaluation indicators; Based on the original data matrix and the type of evaluation indicators, a matrix standardization formula is used to generate a standardized evaluation matrix , the matrix normalization formula is:

The decision matrix calculation formula is:

[0037] in, Indicates the decision matrix i The first wind-solar ratio coupled hydrogen production system j The data corresponding to the original data of the evaluation indicators.

[0039] in, m Indicates that there is m Different wind and solar ratios coupled with hydrogen production systems, n Indicates that each wind-solar ratio coupled hydrogen production system has n evaluation indicators.

[0040] Furthermore, in order to compare different types of indicators, it is necessary to make the values ​​of each indicator in the matrix dimensionless, which is called standardization. The selection of standardization methods should be classified according to the indicator type. Generally, indicators are divided into two categories, benefit indicators and cost indicators. Then, benefit indicators are standardized and cost indicators are standardized:

[0047] In an embodiment of the present invention, following the aforementioned embodiment, the entropy value and the coefficient of difference of each indicator can be calculated based on the standardized evaluation matrix. The change trends of the entropy value and the coefficient of difference are opposite. The coefficient of difference reflects the degree of difference of each evaluation object in the th evaluation indicator. Based on this, the weight of each indicator can be calculated.

The positive ideal solution calculation formula is:

[0049] in, is a positive ideal solution, is a negative ideal solution.

[0050] In the embodiment of the present invention, the positive ideal solution and the negative ideal solution refer to preset parameters for judging the difference between the coupled hydrogen production system and the ideal working state. The positive ideal solution refers to the coupled hydrogen production system working in a good ideal state, and the negative ideal solution refers to the coupled hydrogen production system working in a bad ideal state. For an excellent coupled hydrogen production system, its actual solution should be closer to the positive ideal solution and farther from the negative ideal solution.

[0052] In the embodiment of the present invention, the Euclidean distance calculation formula is used to calculate the first Euclidean distance between the weighted decision matrix corresponding to each wind-solar ratio coupled hydrogen production system and the positive ideal solution and the second Euclidean distance between the weighted decision matrix and the negative ideal solution. The Euclidean calculation formula is:

[0053] in, For the i The first Euclidean distance between the weighted decision matrix of the wind-solar ratio coupled hydrogen production system and the positive ideal solution, For the i The weighted decision matrix of a wind-solar ratio coupled hydrogen production system and the second Euclidean distance of the negative solution.

[0054] The preset relative closeness calculation formula is used to calculate the relative closeness of each wind-solar ratio coupled hydrogen production system. The relative closeness calculation formula is:

[0055] in, is the relative closeness of the i-th wind-solar ratio coupled hydrogen production system.

[0056] In the embodiment of the present invention, the relative closeness Use ratio to express the pros and cons of the solution. If the relative closeness The larger the value is, the closer the scheme is to the ideal solution distance and the farther it is from the negative ideal solution distance, and the better its comprehensive benefits are. Therefore, the relative closeness of the hydrogen production system coupled with each wind-solar ratio can be calculated. Sort them in order from largest to smallest, and set the relative closeness The largest wind-solar-ratio coupled hydrogen production system is determined as the target wind-solar-ratio coupled hydrogen production system.
