Description

Technical Field

[0001] The present application relates to the field of electric power technology, and in particular to a method, device, electronic device and readable storage medium for evaluating expected frequency modulation mileage. Background Art

[0002] Frequency regulation mileage refers to the total frequency regulation mileage in a certain period of time, which is the sum of the adjustment mileage of the power generation unit in response to the AGC (Automatic Generation Control) control command during this period. Frequency regulation mileage is a key indicator for quantifying the frequency regulation contribution of power generation members in the frequency regulation market. The income of power generation members in the frequency regulation market includes mileage income and capacity income, which can be expressed as:

[0003] Q g =D g p D +R g p R

[0004] In the formula, Q g is the frequency regulation market revenue of power generation member g, D g is the frequency modulation mileage, p D is the mileage price, R g is the frequency modulation capacity, p R The price is based on capacity.

[0005] Among them, the frequency regulation capacity and capacity price are obtained through bidding in the frequency regulation market, and the frequency regulation mileage is obtained through statistics of actual responses of market members. The mileage price is a basic market parameter and is determined in advance by market trading rules. In the current design of frequency regulation market trading rules, the frequency regulation capacity price is much lower than the mileage price, so the frequency regulation mileage income is the main source of income for power generation members participating in the frequency regulation market. Therefore, it is expected that the frequency regulation mileage assessment will become an important technical requirement for power generation members to participate in frequency regulation market transactions.

[0006] The so-called expected frequency regulation mileage assessment refers to the analytical process of power generation members evaluating their frequency regulation mileage in the future for a long period of time. It is an important parameter for evaluating the benefits of power generation members in the frequency regulation market, and supports the feasibility verification of the technical transformation of frequency regulation performance of market members. With the continuous deepening of power market reform, power frequency regulation market revenue has become an important source of income for power generation companies in the power market, and the importance of expected frequency regulation mileage assessment has become increasingly prominent. Related technologies Expected frequency regulation mileage assessment is based on the analysis of frequency regulation performance indicators, such as Figure 1As shown, it includes two steps: (1) Counting the frequency regulation mileage distribution of power generation members under different frequency regulation performance. The purpose of this step is to count the frequency regulation mileage of market members under different frequency regulation performance and analyze their distribution rules; (2) Expected frequency regulation mileage evaluation based on frequency regulation performance comparison. The purpose of this step is to evaluate the expected frequency regulation mileage of market members to be evaluated based on the frequency regulation performance indicators of the market members to be evaluated and the distribution of frequency regulation mileage of market members under the frequency regulation performance range. Generally, the mode of the frequency regulation mileage of market members under the frequency regulation performance range is used as the expected frequency regulation mileage evaluation result of the market members to be evaluated. However, the expected frequency regulation mileage evaluation result based on the comparative analysis of frequency regulation performance cannot accurately reflect the frequency regulation mileage of power generation members in the future time period.

[0059] In order to enable those skilled in the art to better understand the scheme of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0060] The terms "including" and "having" and any variations thereof in the specification and claims of the present application and the above-mentioned drawings are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device comprising a series of steps or units is not limited to the listed steps or units, but may include steps or units that are not listed. Various non-limiting embodiments of the present application are described in detail below.

[0061] See first Figure 2 , Figure 2 A flowchart of a method for evaluating expected frequency modulation mileage provided by an embodiment of the present invention is provided. The embodiment of the present invention may include the following contents:

[0062] S201: Obtain the operating parameters and market public parameters of the power generation member to be evaluated.

[0063] The operating parameters of this step are some parameters of the power generation member to be evaluated. The operating parameters include but are not limited to its own frequency regulation performance and expected bid price, where its own frequency regulation performance can be obtained by statistics of its historical operation data or by evaluation based on frequency regulation performance test data, and the expected bid price is the bid price of its frequency regulation capacity market transaction. Market public parameters are all market public information and can be obtained through information disclosure by the dispatching agency. They include but are not limited to the clearing price of frequency regulation capacity, frequency regulation capacity of market members, frequency regulation performance of market members, and frequency regulation mileage of market members.

[0064] S202: Determine the frequency regulation capacity of the power generation member to be evaluated based on the operating parameters, the frequency regulation capacity clearing price and frequency regulation performance of the target power generation member in the market public parameters.

[0065] Frequency regulation mileage is essentially a quantitative indicator of the output adjustment range generated by the rapid adjustment of power generation output by power generation members in response to the power grid frequency regulation demand in actual operation. The concept of frequency regulation mileage can be described as follows Figure 3As shown in the figure, the horizontal axis represents a frequency regulation control cycle of the frequency regulation market, which is generally 10 minutes, and the vertical axis represents the power generation output in the frequency regulation response of the power generation member. The figure compares the difference in frequency regulation mileage between two power generation members with different frequency regulation performance and frequency regulation capacity. The frequency regulation performance of power generation member L1 is better than that of power generation member L2, so it reaches the specified power generation output requirement faster within the frequency regulation control cycle, which is manifested by a larger slope of its frequency regulation mileage; and although the frequency regulation performance of power generation member L2 is inferior to that of power generation member L1, its frequency regulation capacity is larger, and its frequency regulation mileage is actually higher than that of power generation member L1 within the specified frequency regulation control cycle. It can be seen that the factors that determine the difference in frequency regulation mileage among market members include two aspects: frequency regulation capacity and frequency regulation performance. Overall, the larger the frequency regulation capacity, the higher the expected frequency regulation mileage; the better the frequency regulation performance, the higher the frequency regulation mileage. This step is used to determine the frequency regulation capacity of the power generation member to be evaluated.

[0066] Among them, the target power generation member is any power generation member in the frequency regulation market, and technicians in the relevant field can flexibly select it according to actual needs. The frequency regulation capacity clearing price of this step can be obtained from the public information of the market, and the frequency regulation performance is the own parameter of the target power generation member. This step can obtain the relationship between the frequency regulation performance of any power generation member and the historical frequency regulation capacity clearing price data by fitting the two, and then the frequency regulation capacity of the power generation member to be evaluated can be determined by the operating parameters of the power generation member to be evaluated.

[0067] S203: Construct a frequency regulation mileage evaluation model based on the historical frequency regulation capacity, historical frequency regulation performance and historical frequency regulation mileage of each power generation member.

[0068] In this step, the relationship between frequency regulation mileage, frequency regulation capacity and frequency regulation performance can be obtained by fitting the historical data of different power generation members. Since the relationship between frequency regulation mileage, frequency regulation capacity and frequency regulation performance of each power generation member is approximately the same, it can be used as a basis for predicting the frequency regulation mileage when the subsequent frequency regulation performance is known.

[0069] S204: Based on the frequency regulation mileage evaluation model, the expected frequency regulation mileage of the power generation member to be evaluated is obtained according to its own frequency regulation performance in the operating parameters and the frequency regulation capacity of the power generation member to be evaluated.

[0070] In the technical solution provided in the embodiment of the present invention, when conducting expected frequency regulation mileage, the relationship between the declared price and the frequency regulation capacity is determined through the historical data of the frequency regulation market of any power generation member, thereby determining the frequency regulation capacity of the power generation member to be evaluated, and then comprehensively considering the influencing factors of frequency regulation capacity and frequency regulation performance to evaluate the expected frequency regulation mileage, thereby effectively improving the accuracy of the expected frequency regulation mileage evaluation.

[0071] In the above embodiment, there is no limitation on how to perform step S202. An optional implementation in this embodiment may include the following contents:

[0072] According to the equivalent declared price of the target power generation member and the historical average frequency regulation capacity, the corresponding relationship between the equivalent declared price and the frequency regulation capacity is determined; the equivalent declared price is the corresponding frequency regulation capacity clearing price;

[0073] Based on the correspondence between the equivalent declared price and the frequency regulation capacity, the frequency regulation capacity of the power generation member to be evaluated is determined according to the expected declared price in the operating parameters and its own frequency regulation performance.

[0074] In this embodiment, in order to evaluate the expected frequency regulation capacity of power generation members. The current frequency regulation capacity clearing in the frequency regulation market takes the lowest equivalent declared price as the optimization goal. The so-called equivalent declared price refers to the ratio of the declared price to the frequency regulation performance. The original intention of the design of this market transaction method is to give priority to calling power generation members with good frequency regulation performance on the basis of reducing the transaction cost of the frequency regulation market. Since the declared price of market members is private information, the current frequency regulation capacity clearing adopts the marginal clearing method, that is, the equivalent declared price of the winning market member should be lower than the equivalent declared price calculated by the clearing price, so the declared price of each power generation member can be replaced by the clearing price of the frequency regulation capacity of the day, and the frequency regulation capacity of the object to be evaluated will not be enlarged. The equivalent declared price of any power generation member on a certain operating day is the ratio of the declared price of the frequency regulation capacity on that day to its frequency regulation performance, and the equivalent declared price of the power generation member in the statistical period is the average value of the equivalent declared prices of each operating day in the period. As an optional implementation method, the calculation based on the corresponding relationship between the equivalent declared price and the frequency regulation capacity can be carried out in the following way:

[0075] The equivalent price relationship formula is called to calculate the average equivalent declared price of the target power generation members; the equivalent price relationship formula can be expressed as:

[0076]

[0077] The historical frequency regulation capacity relationship is called to calculate the historical average frequency regulation capacity of the target power generation member; the historical frequency regulation capacity relationship can be expressed as:

[0078]

[0079] Since the frequency regulation market capacity clearing takes the minimum equivalent declared price as the optimization goal, this embodiment can use a linear function to construct a correlation evaluation model between frequency regulation capacity and equivalent declared price, that is, the declared price-frequency regulation capacity relationship. Then, according to the obtained multiple groups of average equivalent declared prices and multiple groups of historical average frequency regulation capacities of target power generation members, the parameters of the declared price-frequency regulation capacity relationship can be obtained through fitting calculations such as the least squares method; the declared price-frequency regulation capacity relationship can be expressed as:

[0080]

[0081] According to the parameter a of the declared price-frequency modulation capacity relationship 1 、b 1 , determine the corresponding relationship between equivalent declared price and frequency regulation capacity;

[0082] in, is the equivalent declared price of target power generation member g on operation day d, is the average equivalent declared price of target power generation member g during the statistical period, ND is the number of days in the statistical period, is the clearing price of the frequency modulation market capacity transaction on the operation day, K g is the frequency regulation performance of the target power generation member g; is the historical average frequency regulation capacity of the target generation member g during the statistical period, is the frequency regulation capacity of the target generation member g on operation day d; a 1 、b 1 are the parameters of the declared price-frequency regulation capacity relationship, which are the linear term coefficient and the constant term coefficient of the correlation assessment model respectively.

[0083] After determining the corresponding relationship between the equivalent declared price and the frequency regulation capacity, the frequency regulation capacity of the power generation member to be evaluated can be calculated by calling the frequency regulation capacity relationship formula; the frequency regulation capacity relationship formula can be expressed as:

[0084]

[0085] In the formula, R S is the frequency regulation capacity of the power generation member to be evaluated, a 1 、b 1 is the parameter of the relationship between declared price and frequency regulation capacity, p S is the expected declared price, K S For its own frequency modulation performance.

[0086] The above embodiment does not limit how to execute S203. The present application also provides an optional implementation method for constructing a frequency modulation mileage evaluation model, which may include the following contents:

[0087] In this embodiment, a binary linear function can be used to construct a frequency modulation mileage evaluation model that takes into account frequency modulation capacity and frequency modulation performance. The frequency modulation mileage evaluation model can be expressed as:

[0088]

[0089] According to the multiple sets of historical frequency regulation mileages of the target power generation members, and the historical average frequency regulation capacity and historical frequency regulation performance corresponding to each set of historical frequency regulation mileages, the parameters a of the frequency regulation mileage evaluation model can be calculated by fitting algorithms such as the least squares method. 2 、b 2 、c2 ;

[0090] Where, L g is the historical frequency regulation mileage of the target power generation member g, K g is the historical frequency regulation performance of the target generation member g; is the historical average frequency regulation capacity of the target generation member g during the statistical period, a 2 、b 2 、c 2 are the parameters of the frequency regulation mileage evaluation model, which are the first-order coefficient of frequency regulation capacity, the first-order coefficient of frequency regulation performance and the constant coefficient of the evaluation model.

[0091] Since the frequency regulation mileages of each power generation member in the frequency regulation market are similar, the frequency regulation mileage evaluation model obtained by fitting a large amount of historical data can be used to predict the expected frequency regulation mileage of the power generation member to be evaluated. 2 、b 2 、c 2 , replace the corresponding parameters with those of the object to be evaluated, that is, calculate the expected frequency regulation mileage of the object to be evaluated, that is, the power generation member to be evaluated. That is, based on the frequency regulation mileage evaluation model, determine the expected frequency regulation mileage calculation formula corresponding to the power generation member to be evaluated; the expected frequency regulation mileage calculation formula can be expressed as:

[0092] L S =a 2 R S +b 2 K S +c 2 ;

[0093] Where, L S is the expected frequency regulation mileage of the power generation member to be evaluated, is the frequency regulation capacity of the power generation member to be evaluated, K S For its own frequency modulation performance.

[0094] It should be noted that there is no strict order of execution between the steps in this application. As long as they comply with the logical order, these steps can be executed simultaneously or in a certain preset order. Figure 2 This is just a schematic and does not mean that this is the only execution order.
