Background
The frequency modulation mileage refers to the total frequency modulation mileage in a certain period of time, which is the sum of the adjustment mileage of the power Generation unit responding to an AGC (Automatic Generation Control) Control command in the period of time. The frequency modulation mileage is a key index for quantifying the frequency modulation contribution of power generation members in the frequency modulation market, and the income of the power generation members in the frequency modulation market comprises mileage income and capacity income, and can be expressed as follows:
Q g ＝D g p D +R g p R
in the formula, Q g For the Power Generation Member g, the market revenue of frequency modulation, D g For frequency-modulated mileage, p D For mileage price, R g To frequency-modulated capacity, p R Is the capacity price.
The capacity and the capacity price of the frequency modulation are obtained by bidding in a frequency modulation market, the frequency modulation mileage is obtained by actual response statistics of market members, and the mileage price is used as a market basic parameter and is determined in advance by market trading rules. In the current frequency modulation market trading rule design, the frequency modulation capacity price is far lower than the mileage price, so the frequency modulation mileage income is a main income source for power generation members to participate in the frequency modulation market. Therefore, frequency modulated mileage evaluation is expected to become an important technical requirement for power generation members to participate in frequency modulated market trading.
The expected frequency modulation mileage evaluation refers to an analysis process of evaluating the frequency modulation mileage of a power generation member in a long time in the future, and is an important parameter for evaluating the income of the power generation member in the frequency modulation market so as to support the feasibility verification of the technical transformation of the frequency modulation performance of the market member. With the continuous and deep innovation of the power market, the income of the power frequency modulation market becomes an important income source of power generation enterprises in the power market, and the importance of the expected frequency modulation mileage evaluation is more prominent. The related art expected fm mileage evaluation is based on fm performance index analysis, as shown in fig. 1, which includes two steps: (1) And counting the distribution of the frequency-modulated mileage of the power generation members under different frequency-modulated performances. The implementation purpose of the step is to count the frequency modulation mileage of market members under different frequency modulation performances and analyze the distribution rule of the mileage; (2) And evaluating expected frequency modulation mileage based on frequency modulation performance comparison. The implementation purpose of the step is to evaluate the expected frequency modulation mileage of the market members under the frequency modulation performance interval according to the frequency modulation performance indexes of the market members to be evaluated and by combining the frequency modulation mileage distribution of the market members under the frequency modulation performance interval. Generally, the mode of the frequency modulation mileage of market members in the frequency modulation performance interval is used as an expected frequency modulation mileage evaluation result of the market members to be evaluated. However, the expected frequency modulation mileage evaluation result based on the comparison analysis of the frequency modulation performance cannot accurately reflect the frequency modulation mileage of the power generation member in the future time period.
In view of this, how to improve the accuracy of the estimation of the expected frequency modulation mileage is a technical problem to be solved by those skilled in the art.

Various non-limiting embodiments of the present application are described in detail below.
Referring to fig. 2, fig. 2 is a schematic flow chart of a method for estimating expected fm mileage according to an embodiment of the present invention, where the embodiment of the present invention includes the following steps:
s201: and obtaining the operation parameters and the market open parameters of the power generation members to be evaluated.
The operation parameters of the step are some parameters of the power generation members to be evaluated, the operation parameters of the step include but are not limited to self frequency modulation performance and expected declared price, wherein the self frequency modulation performance can be obtained by statistics of historical operation data of the power generation members or by evaluation according to frequency modulation performance test data, and the expected declared price is the frequency modulation capacity market transaction declared price of the power generation members. The market public parameters belong to market public information and can be obtained through information disclosure of a scheduling mechanism, and include but are not limited to the frequency modulation capacity clearing price, the frequency modulation capacity of market members, the frequency modulation performance of market members and the frequency modulation mileage of market members.
S202: and determining the frequency modulation capacity of the power generation member to be evaluated according to the operation parameters, the frequency modulation capacity clearing price and the frequency modulation performance of the target power generation member in the market public parameters.
The frequency modulation mileage is essentially an output adjustment amplitude quantization index generated by the power generation output quick adjustment responding to the power grid frequency modulation requirement in the actual operation of the power generation member. Concept of frequency modulation mileageAs shown in fig. 3, the abscissa represents a frequency modulation control period of the frequency modulation market, typically 10 minutes, and the ordinate represents the generated output in the frequency modulation response of the power generation members. The frequency-modulation mileage difference of 2 power generation members with different frequency-modulation performances and frequency-modulation capacities is compared in the graph, and the power generation member L 1 The frequency modulation performance of the composite material is superior to that of the power generation member L 2 Therefore, the specified power generation output requirement is achieved more quickly in the frequency modulation control period, and the slope of the frequency modulation mileage is larger; and the power generation member L 2 Although the frequency modulation performance is inferior to the power generation member L 1 However, the frequency modulation capacity is larger, and the frequency modulation mileage is actually higher than the power generation member L in the specified frequency modulation control period 1 . It can be seen that the factors determining the difference of frequency modulation mileage of market members include two aspects of frequency modulation capacity and frequency modulation performance. The larger the frequency modulation capacity is, the higher the expected frequency modulation mileage is; the better the frequency modulation performance, the higher the frequency modulation mileage. The step is used for determining the frequency modulation capacity of the power generation member to be evaluated.
Wherein, the target power generation member is any power generation member in the frequency modulation market, and the skilled person can flexibly select the target power generation member according to the actual requirement. The frequency modulation capacity clearing price of the step can be obtained from market public information, and the frequency modulation performance is the self parameter of the target power generation member. In the step, the relation between the frequency modulation performance of any power generation member and the historical frequency modulation capacity clearing price data can be obtained by fitting the frequency modulation performance of the power generation member and the historical frequency modulation capacity clearing price data, and then the frequency modulation capacity of the power generation member to be evaluated can be determined through the self operation parameters of the power generation member to be evaluated.
S203: and constructing a frequency modulation mileage evaluation model according to the historical frequency modulation capacity, the historical frequency modulation performance and the historical frequency modulation mileage of each power generation member.
The relation between the frequency modulation mileage and the frequency modulation capacity and the frequency modulation performance can be obtained through fitting calculation of historical data of different power generation members, and the relation between the frequency modulation mileage and the frequency modulation capacity and the frequency modulation performance of each power generation member can be approximately the same, so that the relation can be used as a basis for predicting the frequency modulation mileage under the condition that the subsequent frequency modulation performance is known.
S204: and obtaining the expected frequency modulation mileage of the power generation member to be evaluated based on the frequency modulation mileage evaluation model according to the self frequency modulation performance in the operation parameters and the frequency modulation capacity of the power generation member to be evaluated.
According to the technical scheme provided by the embodiment of the invention, when the expected frequency modulation mileage is carried out, the relation between the declared price and the frequency modulation capacity is determined through historical data of the frequency modulation market of any power generation member, so that the frequency modulation capacity of the power generation member to be evaluated is determined, influence factors of the frequency modulation capacity and the frequency modulation performance are comprehensively considered, the expected frequency modulation mileage is evaluated, and the accuracy of the expected frequency modulation mileage evaluation is effectively improved.
In the foregoing embodiment, how to execute step S202 is not limited, and an optional implementation manner in this embodiment may include the following:
determining a corresponding relation between the equivalent declared price and the frequency modulation capacity according to the equivalent declared price and the historical average frequency modulation capacity of the target power generation member; the equivalent declaration price is the corresponding clearing price of the frequency modulation capacity;
and determining the frequency modulation capacity of the power generation member to be evaluated according to the expected declared price and the self frequency modulation performance in the operation parameters based on the corresponding relation between the equivalent declared price and the frequency modulation capacity.
In this embodiment, the capacity of the desired frequency modulation for the power generation member is evaluated. The frequency modulation capacity clearing in the current frequency modulation market takes the minimum equivalent declared price as an optimization target, wherein the equivalent declared price is the ratio of the declared price to the frequency modulation performance. The initial purpose of the market trading mode design is to preferentially call power generation members with good frequency modulation performance on the basis of reducing the frequency modulation market trading cost. Because the declared prices of the market members belong to private information, and the current frequency modulation capacity clearing adopts a marginal clearing mode, namely the equivalent declared prices of the winning market members are all lower than the equivalent declared prices calculated from the clearing prices, the reported prices of the generating members can be replaced by the daily frequency modulation capacity clearing prices, and the frequency modulation capacity of the object to be evaluated cannot be amplified. As an optional implementation manner, the calculation according to the corresponding relationship between the equivalent declared price and the frequency modulation capacity can be implemented in the following manner:
calling an equivalent price relational expression, and calculating the average equivalent declaration price of the target power generation member; the equivalent price relationship can be expressed as:
calling a historical frequency modulation capacity relational expression, and calculating the historical average frequency modulation capacity of the target power generation member; the historical fm capacity relationship may be expressed as:
since the capacity clearance of the frequency modulation market takes the minimum equivalent declared price as an optimization target, the embodiment can adopt a linear function to construct a correlation evaluation model of the frequency modulation capacity and the equivalent declared price, namely, a declared price-frequency modulation capacity relational expression. Then according to the obtained multiple groups of average equivalent declaration prices and multiple groups of historical average frequency modulation capacities of the target power generation members, parameters of a declaration price-frequency modulation capacity relational expression can be obtained through fitting calculation such as a least square method; the declared price-fm capacity relationship may be expressed as:
parameter a according to the declared price-modulated capacity relation 1 、b 1 Determining the corresponding relation between the equivalent declaration price and the frequency modulation capacity;
wherein,
equivalent declaration price for target generating member g on operating day d, < >>
The average equivalent declaration price of the target power generation member g in the statistical period is shown, ND is the number of days in the statistical period, and the number of the hours is greater than or equal to>
Clearing price for running day d FM market capacity trading, K g The frequency modulation performance of a target power generation member g; />
Historical average frequency modulation capacity for target generation member g over a statistical period, based on a statistical time>
The frequency modulation capacity of a target power generation member g on a running day d is set; a is a 1 、b 1 And respectively reporting parameters of a price-frequency modulation capacity relational expression, namely a primary term coefficient and a constant term coefficient of the correlation evaluation model.
After the corresponding relation between the equivalent declaration price and the frequency modulation capacity is determined, the frequency modulation capacity of the power generation member to be evaluated can be calculated by calling a frequency modulation capacity relational expression; the fm capacity relation can be expressed as:
in the formula, R S For the frequency-modulated capacity of the power generation member to be evaluated, a 1 、b 1 For declaring parameters of a price-FM capacity relation, p S To anticipate the declared price, K S The self-frequency modulation performance is achieved.
The above embodiment does not limit how to execute S203, and the application also provides an alternative implementation manner of constructing the frequency-modulated mileage evaluation model, which may include the following:
in this embodiment, a frequency modulation mileage evaluation model considering the frequency modulation capacity and the frequency modulation performance may be constructed by using a binary primary linear function, and the frequency modulation mileage evaluation model may be expressed as:
according to the obtained multiple groups of historical frequency modulation mileage of the target power generation member and the historical average frequency modulation capacity and the historical frequency modulation performance corresponding to each group of historical frequency modulation mileage, each parameter a of the frequency modulation mileage evaluation model can be calculated through a fitting algorithm such as a least square method 2 、b 2 、c 2 ；
In the formula, L g Historical frequency modulation mileage, K, for target power generation member g g Historical frequency modulation performance of a target power generation member g;
historical average frequency modulation capacity of a target power generation member g in a statistical period 2 、b 2 、c 2 Parameters of the frequency modulation mileage evaluation model are respectively a frequency modulation capacity primary term coefficient, a frequency modulation performance primary term coefficient and a constant term coefficient of the evaluation model.
Because the frequency modulation mileage of each power generation member in the frequency modulation market is similar, the expected frequency modulation mileage of the power generation member to be evaluated can be predicted by using a frequency modulation mileage evaluation model obtained based on a large amount of historical data fitting. A determined based on the above embodiment 2 、b 2 、c 2 And replacing the corresponding parameters with the object to be evaluated, namely calculating to obtain the expected frequency modulation mileage of the object to be evaluated, namely the power generation member to be evaluated. Determining an expected frequency modulation mileage calculation relational expression corresponding to the power generation member to be evaluated based on the frequency modulation mileage evaluation model; the expected fm mileage calculation relationship can be expressed as:
L S ＝a 2 R S +b 2 K S +c 2 ；
in the formula, L S The expected frequency modulation mileage of the power generation member to be evaluated, the frequency modulation capacity of the power generation member to be evaluated, K S The self-frequency modulation performance is achieved.
It should be noted that, in the present application, there is no strict sequential execution order among the steps, and as long as the logical order is met, the steps may be executed simultaneously or according to a certain preset order, and fig. 2 is only an exemplary manner, and does not represent that only the execution order is the order.
