Description

Technical Field

[0001] The present invention belongs to the technical field of energy and power, and particularly relates to a new energy storage comprehensive benefit evaluation method, system, device, medium and program considering the time value of funds. Background Art

[0002] As a key link to support the large-scale access and efficient utilization of renewable energy, the importance of new energy storage technology has become increasingly prominent. However, although new energy storage technology shows great potential in promoting energy structure optimization, enhancing the flexibility and resilience of the power system, it still faces many challenges in the field of value evaluation and comprehensive benefit analysis. The deficiencies in the existing technical system limit the healthy and rapid development of the new energy storage industry.

[0003] First of all, technical complexity is a major problem in the comprehensive benefit evaluation of new energy storage. There are many types of new energy storage technologies, including but not limited to pumped storage, compressed air energy storage, flywheel energy storage, and electrochemical energy storage, etc. Each technology has its unique physical characteristics, economic costs, and environmental impacts. This diversity not only requires the evaluation model to have a high degree of flexibility and adaptability to accurately capture the nuances of different technologies, but also exacerbates the complexity of data collection, processing, and analysis. In addition, new energy storage systems are often deeply coupled with other components of the power system, and the comprehensive benefit evaluation needs to comprehensively consider multiple dimensional factors such as grid structure, load characteristics, and policy environment, further increasing the technical difficulty of the evaluation work.

[0004] Secondly, slow calculation speed is another key factor restricting the application of existing evaluation technologies. In a complex power system environment, the comprehensive benefit evaluation of new energy storage systems involves the real-time processing and dynamic simulation of a large amount of data, which poses extremely high requirements for computing power and algorithm efficiency. Traditional evaluation methods are often based on static or simplified system models and are difficult to accurately reflect the dynamic changes of energy storage systems in actual operation and their impacts on the overall performance of the power system. As the scale of the power system expands and the penetration rate of renewable energy increases, the errors caused by this simplified processing will gradually accumulate, ultimately affecting the accuracy and reliability of the evaluation results. And using a high-precision and high-complexity model for evaluation may lead to an overly long evaluation period due to the huge amount of calculation, unable to meet the needs of the rapid development of the industry.

[0005] Furthermore, there are deficiencies in the existing evaluation technologies in dealing with the time value of funds. For new energy storage systems, especially electrochemical energy storage, their investment costs are high and the replacement cycle is short, and the capital flow within the entire life cycle has significant time value characteristics. However, most current evaluation models fail to fully consider the time cost of funds during construction, resulting in evaluation results that are difficult to truly reflect the actual economic benefits of energy storage projects. This may not only mislead the decisions of investors, but also affect the support of policymakers for the development of new energy storage technologies.

[0006] In summary, due to problems such as complex technology, slow calculation speed, and improper handling of the time value of funds in the existing new energy storage comprehensive benefit evaluation technology, it is impossible to obtain a reasonable new energy storage comprehensive benefit evaluation plan, and the working hours are too long.

[0039] Compared with the prior art, the present invention has the following beneficial effects:

[0040] Through optimizing the evaluation process and algorithm design, the present invention simplifies and accelerates the evaluation process.

Secondly, the present invention demonstrates unique advantages in dealing with the time value of money.

The present invention ensures the accuracy and reliability of evaluation results by introducing a scientific mechanism for dealing with the time value of money, fully considering the value differences of money at different time points. This improvement not only makes the evaluation results closer to the actual situation, but also provides a more scientific basis for investment decisions on energy storage projects, helping investors make more informed choices. In addition, when constructing a comprehensive benefit evaluation model, the present invention comprehensively considers the direct economic benefits, indirect economic benefits and social benefits of the new energy storage system. Traditional evaluation methods often focus on single-dimensional benefit analysis and ignore the positive impacts of energy storage systems on the environment, society and other aspects. The present invention realizes a comprehensive and multi-level benefit evaluation of the energy storage system by constructing a comprehensive benefit evaluation model. This improvement not only makes the evaluation results more comprehensive and objective, but also provides richer information support for the optimal design, policy formulation and market promotion of energy storage projects.

[0041] Finally, the present invention also performs excellently in terms of practicality. By adopting the method of direct program statistics, the present invention realizes the automation and intelligence of the evaluation process, meeting the needs of batch data calculation. This improvement not only reduces labor costs and improves work efficiency, but also makes the evaluation results easier to manage and analyze. At the same time, the calculation process of the present invention is simple and easy to understand, facilitating technicians to quickly master and apply, providing a strong technical guarantee for the rapid development of the new energy storage industry.

[0049] Glossary:

[0050] New energy storage: refers to energy storage technologies other than pumped storage that mainly output electricity, and is an important supporting technology for building a new power system with new energy as the main body.

[0051] Aiming at the problems existing in the prior art, that is, the existing new energy storage comprehensive benefit evaluation technology is difficult to meet the needs of the rapid development of the industry due to its complex technology, slow calculation speed and improper handling of the time value of funds, the present invention provides a new energy storage comprehensive benefit evaluation method considering the time value of funds. As Figure 1 shown, this method includes:

[0052] S100: Obtain the basic data of the benefit evaluation model;

[0053] S200: Obtain the direct economic benefits of the new energy storage system according to the basic data of the benefit evaluation model;

[0054] S300: Obtain the indirect economic benefits of the new energy storage system based on the economic benefits of power generation enterprises, grid enterprises and users, and obtain the social benefits of the new energy storage system based on the environmental benefits of pollutant emissions;

[0055] S400: Build a comprehensive benefit evaluation model based on the direct economic benefits, indirect economic benefits, and social benefits of the new energy storage system;

[0056] S500: Obtain the evaluation results of the new energy storage benefits according to the comprehensive benefit evaluation model, and design a comprehensive benefit evaluation plan for the new energy storage.

[0057] The calculation process of this method is simple, the calculation speed can be greatly improved, and it can be directly counted by a program, meeting the needs of batch data calculation, avoiding problems caused by improper handling of the time value of funds, and saving man-hours.

[0058] As Figure 2 described, the present invention provides a method for evaluating the comprehensive benefits of a new energy storage considering the time value of funds, and the specific steps are as follows:

[0059] S1: Collect the basic data for the benefit evaluation model, including project basic parameters, battery technical indicators of the new energy storage power station, project investment situation, financial parameters, cost parameters, etc.;

[0060] Among them, the data sources can be project designs, bidding documents, etc., and the financial parameters and cost parameters can be obtained from publicly known data;

[0061] The basic data should be data that can fully reflect market information and can reflect the change information of the data during the project operation period;

[0062] S2: Calculate the direct economic benefits of the new energy storage system. The direct economic benefits are the direct economic benefits obtained from the peak-valley arbitrage of the new energy storage system, which are directly related to the system capacity, charge-discharge times, charge-discharge depth, peak-valley price difference, and charge-discharge efficiency of the new energy storage system. Among them, the system capacity, charge-discharge times, charge-discharge depth, peak-valley price difference, and charge-discharge efficiency are obtained from the project basic parameters.

[0063] Specifically, the following formula can be used for calculation:

[0064]

[0065] In the formula: DEP is the direct economic benefit, unit: ten thousand yuan; VESS is the system capacity, unit: kw; T is the charge-discharge time, unit: h; DEPTH is the charge-discharge depth, unit: dimensionless; PI is the peak-time electricity price, yuan / kw.h; PO is the valley-time electricity price, yuan / kw.h; η is the charge-discharge efficiency, unit: dimensionless.

[0066] Among them, considering the time variation factor, the charge-discharge depth and charge-discharge efficiency are modified as the following formula:

[0067]

[0068] In the formula: n is the service life, unit: year.

[0069] S3: Calculate the indirect economic benefits of the new energy storage system and the social benefits of the new energy storage system;

[0070] Calculate the indirect economic benefits of the new energy storage system. The indirect economic benefits include the economic benefits brought by the new energy storage system to power generation enterprises, power grid enterprises, and users.

[0071] The economic benefits brought to power generation enterprises can be converted into equivalent benefits such as the transformation of existing units and the addition of peak shaving equipment; the benefits brought to power grid enterprises can be converted into equivalent benefits of power grid system transformation; the benefits brought to users can be converted into equivalent benefits of user electricity price gains and losses.

[0072] Calculate the social benefits of the new energy storage system. The social benefits mainly include environmental benefits reflected in reducing pollutant emissions; the environmental benefits of reducing pollutant emissions can adopt equivalent benefits of reducing CO2 or other pollutant emissions.

[0073] Considering the time value of funds, discount the direct economic benefits, indirect economic benefits, and social benefits; the time value of funds takes the social average discount rate. If considering the change of the social average discount rate over time, the dynamic social average discount rate can be taken. Among them, SDR is the dynamic social average discount rate, unit: dimensionless.

[0074] S4: Summarize the direct economic benefits, indirect economic benefits, and social benefits to finally obtain a comprehensive benefit evaluation model. The model can be summarized using computer language and visualized to meet the needs of popularization and application.

[0075] Summarize the direct economic benefits, indirect economic benefits, and social benefits to obtain the comprehensive benefits of the project; since the benefits of the project have a time span and the benefit values in different years may be different, the time value of funds needs to be considered. The time value of funds reflects the value change of funds at different time points and is usually discounted using the discount rate. For the comprehensive benefit evaluation of energy storage projects, an appropriate discount rate should be selected to discount future benefits.

[0076] Construct a comprehensive benefit evaluation model based on the total comprehensive benefits;

[0077] According to the comprehensive benefit evaluation model, calculate the evaluation results of the new energy storage benefits;

[0078] Based on the evaluation results of the new energy storage benefits, design a comprehensive benefit evaluation plan for the new energy storage.

[0079] In summary, the novel energy storage comprehensive benefit evaluation method considering the time value of funds provided by the present invention can dynamically consider the dynamic changes of the social average discount rate on the basis of ensuring a relatively reasonable evaluation of the comprehensive benefits of novel energy storage, thereby providing support for engineering design and decision-making. The calculation process of the comprehensive benefit evaluation of the novel energy storage provided by the present invention is relatively simple and straightforward, the calculation speed can be greatly improved, and it can be implemented by programming, which can be better applied to engineering design and save working hours. Compared with the prior art, the present invention realizes the evaluation of the comprehensive benefits of novel energy storage, comprehensively considers the direct economic benefits, indirect economic benefits and social benefits, can relatively reasonably evaluate the benefits of novel energy storage, is conducive to the healthy and sustainable development of the novel energy storage industry, and provides good support for engineering design.
