Description

Technical Field

[0002] The direction of energy and power transformation is to accelerate the development of new energy sources and restrict the construction of new inefficient thermal power plants. This places higher demands on the low-carbon transformation of power transmission networks. Due to differences in topography, geographical location, and historical background, there are differences in energy development between regions, resulting in regional differences in power transmission networks. As energy and power transformation progresses, power transmission networks will reveal some significant problems. For example, the development of regional power transmission networks relying on traditional thermal power generation will be limited, and the installed capacity of new energy sources in regions with high wind and solar curtailment rates will be significantly reduced. Currently, most existing technical solutions focus on specific regions and do not study the comprehensive performance evaluation of power transmission networks in different regions from a low-carbon and energy-saving perspective. They cannot objectively compare and evaluate the current development status of power transmission networks in different regions, and therefore cannot propose corresponding improvement suggestions to address the current shortcomings of the power transmission network and promote the transformation of energy and power.

[0057] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0058] The purpose of this invention is to provide a method, system, electronic device, and storage medium for evaluating the performance of a power transmission network, so as to achieve a comprehensive evaluation of the performance of the power transmission network in each target area.

[0059] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0060] This invention provides a method for evaluating the performance of power transmission networks, such as... Figure 1 As shown, it includes the following steps:

[0061] Step S1: Establish a performance evaluation system for the power transmission network.

[0062] Figure 3 This diagram illustrates the structure of the power transmission network performance evaluation system. The system comprises three components: low-carbon performance, social performance, and operational performance. Low-carbon performance includes installed capacity of new energy sources, new energy power generation, installed capacity of thermal power plants, and thermal power generation. Social performance includes total electricity consumption, per capita electricity consumption, and per capita residential electricity consumption. Operational performance includes line loss rate, circuit length, and the number of transformers.

[0063] Among them, the installed capacity of new energy, the power generation of new energy, the total electricity consumption of the whole society, the per capita electricity consumption, and the per capita residential electricity consumption are all positive indicators; the installed capacity of thermal power, the power generation of thermal power, the line loss rate, the circuit length, and the number of transformers are all negative indicators.

[0064] Step S2: Obtain the original data of each indicator in the power transmission network performance evaluation system for each target region and each year.

[0065] Step S3: Standardize all the raw data to obtain standardized data.

[0066] The raw data is standardized according to the positive and negative attributes of each indicator:

[0067]

[0068] The formula above the curly braces represents the data processing method for positive indicators, while the formula below the curly braces represents the data processing method for negative indicators. Subsequent calculations are based on the processed data obtained in this step. ij This represents the raw data for the j-th indicator in the i-th year of the target region, x. j Let j represent the j-th indicator, (x j ) min and (x) j ) max Let x′ represent the minimum and maximum raw data of the j-th indicator, respectively. ij This represents the standardized data of the j-th indicator in the i-th year of the target region.

[0069] Step S4: Based on the standardized data, determine the CRITIC weight of each indicator using the CRITIC method.

[0070] The index weight vector was obtained by performing the CRITIC method on the processed data using SPSSAU software.

[0071] The CRITIC method is another objective weighting method proposed by Diakoulaki. Its basic idea is to determine the objective weights of indicators based on two fundamental concepts.

[0072] First, there's the contrast strength, which represents the magnitude of the difference in values ​​between different evaluation schemes for the same indicator, expressed as the standard deviation S. j The standard deviation is expressed in the form of a standard deviation, indicating the magnitude of the difference in values ​​among different options within the same indicator. The larger the standard deviation, the greater the difference in values ​​among the options. Secondly, it evaluates the conflict between indicators. The conflict between indicators is based on their correlation. For example, if two indicators have a strong positive correlation, it indicates that the conflict between the two indicators is low.

[0073]

[0074]

[0075]

[0076] Among them, R j R represents the quantification of the conflict between j indicators and other indicators. kj C is the correlation coefficient between evaluation indicators k and j. j It refers to the information content of the indicator, w j This is the CRITIC weight of the j-th indicator. The indicator weight vector composed of the CRITIC weights of these n indicators is...

[0077] Standard deviation S j It was calculated from standardized data.

[0078] Step S5: Based on the standardized data, determine the entropy weight of each indicator using the entropy weight method.

[0079] The SPSSAU software was used to obtain the index weight vector by applying the entropy weight method to the processed data.

[0080] Entropy, originally a thermodynamic concept, was first introduced into information theory by Shannon and is now widely used in engineering, technology, socio-economics, and other fields. Information entropy can be used to calculate the weights of various indicators, providing a basis for comprehensive evaluation of multiple indicators.

[0081] Generally, if the information entropy E of a certain indicator j The smaller the value, the greater the variability of the indicator value, and therefore the greater its weight should be. Conversely, the larger the information value E of an indicator, the greater its weight. jThe larger the value, the smaller the degree of variation in its indicator value, the less information it provides, and the smaller its role in the comprehensive evaluation. Therefore, its weight should also be smaller.

[0082]

[0083]

[0084]

[0085] Where, p ij It is the ratio of each indicator under each plan, E j It is the information entropy of each indicator, w′ j This is the entropy weight of the j-th indicator. The indicator weight vector composed of the entropy weights of these n indicators is... x′ ij This represents the standardized data of the j-th indicator in the i-th year of the target region, where m represents the total number of years.

[0086] Step S6: Based on the game theory-based combined weighting method, the CRITIC weight and entropy weight are combined to determine the combined weight of each indicator.

[0087] Solve the combinatorial weights using Matlab R2018a based on combinatorial game theory.

[0088] The game theory-based combined weighting method is the process of combining weights obtained from different methods to find the most reasonable index weights. Its working principle is to ensure the minimum discrete condition between the combined weights and the weights calculated by the two methods, as follows:

[0089]

[0090] In the formula, z = 1, 2, ∝ k Represents the combination coefficients of the weighting method. This represents one type of basic weight set, which is composed of and Together, they form the index weight vector, which is composed of the CRITIC weights of all indicators. The index weight vector, composed of the entropy weights of all indicators, is... This represents the basic weights before being weighted by combined weights. The objective function aims to find the optimal w. * That is, for the weighting coefficients ∝ k Optimize to make w * With each w k Minimize the deviation between them.

[0091] Based on the differential properties of matrices, the first derivative of the above equation is:

[0092]

[0093] Transforming the above expression into a system of linear equations, we have:

[0094]

[0095] Solving the above matrix equations using Matlab.R2018a yields the solution (∝1, ∝2). Normalizing this solution, we have:

[0096] The combined weight w is obtained by arbitrarily linearly combining these two vectors. * for:

[0097]

[0098] in, The index weight vector is calculated using the CRITIC method. To calculate the index weight vector using the entropy weight method, ∝ k The combination coefficients of the weighting method.

[0099] Step S7: Determine the comprehensive performance evaluation value of the power transmission network for each target region for each year based on the combined weight of each indicator and the original data of each indicator for each target region for each year.

[0100] Using the obtained combined weight values ​​and the standardized index data, multiply and sum them:

[0101]

[0102] In the formula, S i This represents the comprehensive performance evaluation value of the power transmission network in the target region in year i. Let x′ represent the combined weight of the j-th indicator. ij This represents the standardized data of the j-th indicator in the i-th year of the target region, where n represents the total number of all indicators.

[0103] This invention employs combinatorial game theory, which can largely overcome the single-method shortcomings of the CRITIC method and the entropy weight method, making the weighting results more accurate, scientific, and comprehensive.

[0104] The study evaluated the power transmission network performance of six major regions in China—North China, Central China, East China, Northeast China, Northwest China, and South China—from 2014 to 2020.

[0105] Reference Figure 2The power transmission network performance evaluation method of this invention constructs a power transmission network performance evaluation index system from three aspects: low-carbon performance, social performance, and operational performance. Furthermore, it utilizes a combination of game theory based on the CRITIC method and the entropy weight method to evaluate the power transmission network performance in six regions of China (North China, Northeast China, East China, Central China, Northwest China, and Southern China) from 2014 to 2020. The evaluation results are as follows: Figure 4 As shown.

[0106] By observing and comparing the performance of power transmission networks in different regions from both temporal and geographical perspectives, we can also analyze the most weighted indicators for each region. This makes it easier to propose constructive suggestions for addressing these issues and provides more sufficient evidence for the power transmission network to achieve its low-carbon transformation goals.

[0107] Based on the assessment results, the following improvement measures are proposed: On the one hand, enhance the absorption capacity of new energy in the transmission and distribution network. This can be achieved by vigorously developing the "new energy + energy storage" model, which can smooth power output, improve the grid connection regulation capacity of new energy power generation, and enhance the utilization efficiency of grid equipment. On the other hand, improve the overall energy efficiency of electricity consumption in society, strengthen the demand response capability of users, enable them to actively respond to grid demand, promote the integration of demand-side adjustable resources into the power grid, give full play to the role of time-of-use pricing, release demand-side resources, and promote the balance of power supply and demand.
