It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. All other embodiments, which can be derived by a person skilled in the art from the examples given herein without any inventive step, are within the scope of the present invention.
Examples
Fig. 1 is a flowchart of a method for settling fm auxiliary service fees according to an embodiment of the present invention, where the method may be performed by an apparatus for settling fm auxiliary service fees according to an embodiment of the present invention, and the apparatus may be implemented in software and/or hardware, and referring to fig. 1, the method may specifically include the following steps:
s101, in frequency modulation auxiliary service in a preset time period, when the running state information of the generator set is judged to meet a first preset power generation power standard, calculating the frequency modulation responsivity of the generator set in the preset time period, wherein the preset time periods are multiple, the multiple preset time periods all belong to the whole frequency modulation cycle, the running state information comprises the response time, the response precision and the response speed when the generator set executes a power adjustment instruction, and the frequency modulation responsivity is the working time corresponding to the generator set when the power generation power of the generator set meets a second preset power generation power standard.
Specifically, the entire frequency modulation cycle may be divided into a plurality of preset time periods, and the time length of the preset time periods may be freely specified, for example, the time length of each preset time period is set to be 10 min. The response time of the generator set when executing the power adjustment instruction refers to the time consumed by the generator set from the beginning of adjusting the generating power to the time when the generating power of the generator set reaches 20% of the preset power adjustment amount corresponding to the power adjustment instruction for the first time in the frequency modulation auxiliary service process in the preset time period and after the frequency modulation system issues the power adjustment instruction of the generator set, and the time is recorded as the time consumed by the generator set when the generating power of the generator set reaches 20% of the preset
When the generated power of the generator set reaches 20% of the power adjustment amount corresponding to the power adjustment instruction for the first time, the power formula met by the generated power of the generator set at the moment is as follows:
Pi del-Pi sta＝20％×(Pi set1-Pi sta)
wherein, Pi delIs composed ofThe generated power of the generator set at the moment t1The moment when the frequency modulation system gives the power regulation instruction of the generator set, i.e. the preset time periodInner starting time, Pi staIs t1The generated power P of the generator seti set1Is t1And (3) the target generating power of the generator set corresponding to the power adjusting instruction of the generator set issued by the frequency modulation system at the moment, namely, the generating power of the generator set stops increasing after reaching the target generating power.
Because the shorter the response time of the generator set is, the more sensitive the frequency modulation response of the generator set is, when the response time is less than or equal to the preset response time limit value, the response time of the generator set is judged to be qualified. The formula for judging the response time to be qualified is as follows:
wherein,the power generation device belongs to a first preset power generation power standard and is a preset response time limit value. Only when the generator set has a response time within a preset time periodWhen the judgment formula is satisfied, the response time of the generator set is judgedIf not, judging the response time of the generator setAnd (7) failing to be qualified.
The response precision when the generator set executes the power adjustment instruction refers to the ratio of the actual generated power adjustment quantity of the generator set to the preset generated power adjustment quantity in the frequency modulation auxiliary service process in the preset time period, which is recorded as gammai，γiThe calculation formula of (2) is as follows:
wherein, Pi endThe actual generated power of the generator set at the final moment in the preset time period is obtained.
The higher the response precision of the generator set is, the more the frequency modulation auxiliary service of the generator set meets the frequency modulation requirement of the frequency modulation system, so that when the frequency modulation response precision of the generator set is greater than or equal to the preset response precision limit value, the qualification of the frequency modulation response precision of the generator set is judged. The formula for judging the response accuracy is as follows:
wherein,the preset response accuracy limit value belongs to a first preset power generation power standard. Response accuracy gamma of the generator set only when the generator set is in a preset time periodiWhen the judgment formula is satisfied, the response precision gamma of the generator set is judgediIf not, judging the response precision gamma of the generator setiAnd (7) failing to be qualified.
The response rate when the generator set executes the power adjustment instruction is the increase rate of the generated power of the generator set in the frequency modulation auxiliary service process in the preset time period. The formula for judging the response rate is as follows:
wherein, viResponding to the generator set within a preset time periodThe rate, Δ T, is the preset time period.
Because the faster the response rate of the generator set is, the higher the frequency modulation auxiliary service capability of the generator set is, when the response rate of the generator set is greater than or equal to the preset response rate limit value, the formula for judging that the response rate of the generator set is qualified is as follows:
wherein,the preset response rate limit value belongs to a first preset power generation power standard. Only when the generator set has a response speed v within a preset time periodiWhen the judgment formula is satisfied, the response speed v of the generator set is judgediIf not, judging the response speed v of the generator setiAnd (7) failing to be qualified.
When the response time, the response precision and the response rate of the generator set in the preset time period are qualified, judging that the running state information of the generator set in the preset time period accords with a first preset power generation standard, and judging that the frequency modulation auxiliary service of the generator set is qualified, otherwise, judging that the frequency modulation auxiliary service of the generator set is unqualified. When the frequency modulation auxiliary service of the generator set is judged to be unqualified, recording the frequency modulation responsivity of the generator set as 0, and when the frequency modulation auxiliary service of the generator set is judged to be qualified, determining the working time length of the generator set corresponding to the power generation power of the generator set meeting a second preset power generation power standard according to the actual power generation power condition of the generator set in the whole frequency modulation auxiliary service process, wherein the working time length is the frequency modulation responsivity of the generator set, the second preset power generation power standard can be that the power generation power is within the range of plus or minus 20% of the preset power generation power, and the preset power generation power is the power generation power which the generator set corresponding to the power adjustment instruction finally reaches in a preset time period.
In a specific example, when the power generating unit is a thermal power generating unit of a direct-fired pulverizing system, the corresponding preset response time limit is specified to be 60S, the preset response precision limit is ± 3%, and the preset response rate limit is the generating power, and the variable size per minute is 1% of the rated active power of the power generating unit, that is, the rated active power of the power generating unit is increased or decreased by 1% per minute. And when the response time, the response precision and the response speed of the generator set all meet the corresponding limit values, judging that the frequency modulation auxiliary service of the generator set is qualified. And then determining the working time corresponding to the generator set when the generating power of the generator set is within the range of plus or minus 20% of the preset generating power according to the actual generating condition of the generator set in the whole frequency modulation auxiliary service. The working time is the frequency modulation responsivity of the generator set in a preset time period.

Specifically, the whole frequency modulation cycle is divided into a plurality of preset time periods, and the frequency modulation responsivity corresponding to each preset time period is subjected to preset calculation to obtain a target frequency modulation responsivity corresponding to the whole frequency modulation cycle, where the preset calculation may be weighted calculation. In a specific example, the weights corresponding to the preset time periods are different, after the frequency modulation responsivity corresponding to each preset time period is obtained, the frequency modulation responsivity corresponding to each preset time period is multiplied by the corresponding weight to obtain the weighted frequency modulation responsivity corresponding to each preset time period, and then the weighted frequency modulation responsivities corresponding to each preset time period are summed to obtain the target frequency modulation responsivity corresponding to the whole frequency modulation cycle.
And S103, calculating the actual settlement cost of the frequency modulation auxiliary service of the generator set based on the target frequency modulation responsivity.
Specifically, when the generator set receives the frequency modulation auxiliary service task, theoretical settlement cost of the frequency modulation auxiliary service corresponding to the generator set is determined, and the actual power generation condition of the generator set is not considered in the theoretical settlement cost. After the frequency modulation auxiliary service task of the generator set is finished, the target frequency modulation responsivity is determined according to the actual power generation condition of the generator set, and then the theoretical settlement cost of the frequency modulation auxiliary service corresponding to the generator set is corrected according to the target frequency modulation responsivity so as to determine the actual settlement cost of the frequency modulation auxiliary service corresponding to the generator set.
Illustratively, the first generator set receives a certain frequency modulation auxiliary service task at one million of theoretical settlement cost of the frequency modulation auxiliary service, and after the first generator set completes the frequency modulation auxiliary service task, the target frequency modulation responsiveness corresponding to the first generator set is determined to be 5h, the specified frequency modulation responsiveness standard is 6h, and the target frequency modulation responsiveness of the first generator set does not meet the specified frequency modulation responsiveness standard according to the actual power generation condition of the first generator set in the whole frequency modulation period. Therefore, the theoretical settlement fee of the frequency modulation auxiliary service corresponding to part of the A generator set is deducted, and the actual settlement fee of the frequency modulation auxiliary service corresponding to the A generator set is finally obtained.
By adopting the technical scheme, when the response time, the response precision and the response speed of the generator set are judged to be qualified, the frequency modulation responsivity of the generator set is calculated, and the relevant regulations of the industry are considered, so that the final calculation result meets the requirements of the industry. And counting the working time of the generator set corresponding to the condition that the generating power of the generator set is within the range of plus or minus 20% of the target generating power, and defining the working time as the frequency modulation responsivity of the generator set in a preset time period. When the generated power of the generator set is within the range of plus or minus 20% of the target generated power, the frequency modulation auxiliary service of the generator set is considered to basically meet the frequency modulation requirement, so the frequency modulation responsiveness can reflect the comprehensive benefit of the frequency modulation response of the generator set in the preset time period. And then calculating the target frequency modulation responsivity corresponding to the whole frequency modulation period, and calculating the actual settlement cost of the frequency modulation auxiliary service of the generator set according to the target frequency modulation responsivity, thereby ensuring that the calculation result conforms to the actual running state of the generator set and improving the frequency modulation auxiliary service capability of the generator set.

Specifically, the second preset power generation standard is used for measuring whether the power generation power of the generator set meets the frequency modulation requirement, the value of the second preset power generation standard may be a range value, the working time of the generator set corresponding to the power generation power in the range value is counted, and the comprehensive execution state of the generator set in the frequency modulation auxiliary service can be measured. In a specific example, the second predetermined generated power criterion is a generated power value within plus or minus 20% of the predetermined generated power. The method comprises the steps that a generator set carries out frequency modulation auxiliary service in a preset time period, when the running state information of the generator set is judged to meet a first preset power generation power standard, the power generation power of the generator set in the preset time period is detected, then the power generation power at each moment is compared with a second preset power generation power standard, the power generation power meeting the second preset power generation power standard is determined, and the power generation power is the target power generation power.

The frequency modulation auxiliary service responsiveness of the generator set is quantized, so that the frequency modulation auxiliary service responsiveness of the generator set is judged more simply, and the actual execution condition of the generator set is met.

The calculation method is simple and the popularization is strong.
Further, based on the target frequency modulation responsivity, all the generator sets are subjected to grade division, and the method comprises the following steps: firstly, all the generator sets are sequenced according to the rule that the target frequency modulation responsivity is from large to small to obtain a target responsivity ranking table. And then dividing the names in the name list into preset grades, wherein each grade in the preset grades at least comprises a group of generator sets.
In detail, two groups of generator sets can be selected arbitrarily, the target frequency modulation responsivities corresponding to the two groups of generator sets are compared, the magnitude relation of the target frequency modulation responsivities corresponding to the two groups of generator sets is obtained, and the generator set with the high target frequency modulation responsivity is arranged in front of the generator set with the low target frequency modulation responsivity. And secondly, randomly selecting a third group of generating sets, comparing the target frequency modulation responsivity corresponding to the third group of generating sets with the target frequency modulation responsivity corresponding to the two groups of generating sets respectively to obtain the magnitude relation of the target frequency modulation responsivities corresponding to the three groups of generating sets respectively, and sequencing the three groups of generating sets according to the rule that the target frequency modulation responsivity is from large to small. And then, randomly selecting a fourth group of generating sets, comparing the target frequency modulation responsivity corresponding to the fourth group of generating sets with the target frequency modulation responsivities corresponding to the three groups of generating sets respectively to obtain the magnitude relation of the target frequency modulation responsivities corresponding to the four groups of generating sets respectively, and sequencing the four groups of generating sets according to the rule that the target frequency modulation responsivities are from large to small. And by analogy, a target responsiveness ranking table of all the generator sets according to the rule that the target frequency modulation responsiveness is from large to small is obtained.
When all the titles included in the target responsiveness title table are averagely divided into preset grades, the number of the titles corresponding to each grade, namely, how many titles each grade includes, needs to be determined. Then according to the number of the corresponding names of each grade, the continuously corresponding names starting from the first name are divided into the first grade, then the names included in other grades are divided by the same method, and finally the names in the name list are divided into preset grades, wherein the preset grades can be freely set. When all the titles included in the target responsiveness title table cannot be equally divided by the preset number of grades, the number of the titles included in the last grade can be made less than that of other grades. Illustratively, the number of the generator sets is 98, the preset gear number is 10, after the generator sets are arranged according to a rule that the target frequency modulation responsivity is from high to low, the first to tenth generator sets are arranged into a first gear, the eleventh to twentieth generator sets are arranged into a second gear, and so on, and finally the ninth to ninth eighteenth generator sets are arranged into a tenth gear. The method is simple to operate, strong in implementability and short in time consumption, and can realize grade division of all the generator sets according to the target frequency modulation responsivity in a short time.
Further, according to the corresponding grade of the generator set, determining a corresponding cost correction value of the generator set, including: first, a reward and punishment rule about the grade is established. And then determining the reward and punishment amount corresponding to each grade as a cost correction value according to the reward and punishment rule.
In detail, the reward punishment rule can be that the power plant that the generating set corresponds that leans on the front carries out the reward to the grade, carries out the punishment to the power plant that the generating set that leans on the back corresponds, neither rewards, also punishment to the grade in the power plant that generating set corresponds in the middle. In a specific example, all the generator sets are divided into 10 levels, the reward and punishment rule is to reward the power plants corresponding to the generator sets in the first level and the second level, and the fee correction values corresponding to the generator sets are reward money amounts. And (4) punishing power plants corresponding to the generator sets positioned in the ninth gear and the tenth gear, wherein the cost correction values corresponding to the generator sets are punished money. And the power plants corresponding to the generator sets positioned in the third gear to the eighth gear are not rewarded or penalized, and the cost correction values corresponding to the generator sets are zero.
By formulating a reward and punishment rule, the cost correction value of the generator set is determined according to the reward and punishment rule, the determination process of the cost correction value is fair and reasonable, and the electric power transaction is smoothly carried out.
Further, calculating the actual settlement cost of the frequency modulation auxiliary service of the generator set based on the cost correction value, wherein the step of summing the theoretical settlement cost of the frequency modulation auxiliary service and the cost correction value to obtain the actual settlement cost of the frequency modulation auxiliary service is included.
Specifically, the summation calculation is a calculation of adding both. The actual settlement cost of the frequency modulation auxiliary service corresponding to the generator set is obtained by adding the theoretical settlement cost of the frequency modulation auxiliary service of the generator set and the corresponding cost correction value. The calculation method for realizing the actual settlement cost of the frequency modulation auxiliary service is simple, and the calculation result is fair and reasonable. The actual settlement cost calculation of the frequency modulation auxiliary service of the power plant corresponding to the generator set under different reward and punishment conditions is realized.
For example, when the power plant corresponding to the generator set is rewarded, the modified cost value corresponding to the generator set is a positive value, which is denoted as Awd, and the calculation formula of the actual settlement cost of the corresponding fm auxiliary service is as follows:
wherein, i is a positive integer and represents the serial number of the generator set. Fee represents the cost.The cost is actually settled for the frequency modulation auxiliary service corresponding to the generator set i,and (5) settling the fee for the frequency modulation auxiliary service theory corresponding to the generator set i.
When the power plant corresponding to the generator set is punished, the cost correction value corresponding to the generator set is a negative value and is marked as Pu, and the calculation formula of the corresponding actual settlement cost of the frequency modulation auxiliary service is as follows:
when the power plant corresponding to the generator set is not rewarded or penalized, the calculation formula of the actual settlement cost of the frequency modulation auxiliary service corresponding to the generator set is as follows:
further, the preset calculation includes a summation calculation.
In detail, the frequency modulation responsivity corresponding to each preset time period is summed to obtain the target frequency modulation responsivity corresponding to the whole frequency modulation period. Through summation calculation, the target frequency modulation responsivity of the generator set in the whole frequency modulation period is obtained, and the calculation method is simple and easy to understand.
In a specific example, the calculation formula for calculating the target frequency modulation responsivity is as follows:
wherein, i is a positive integer and represents the serial number of the generator set. t is a positive number and indicates the number of the preset time period. T isi AllFor frequency modulation of generator set i in the whole frequency modulation periodThe responsivity is NT, the time interval number obtained by dividing the whole frequency modulation cycle by the interval of the duration delta T of the preset time interval,and (4) the frequency modulation responsivity of the generator set i in a preset time period t.
