Description

Technical Field

[0002] With the vigorous development of clean energy, a large number of distributed photovoltaics are connected to the power grid. The randomness, intermittency and volatility of distributed photovoltaics have a series of impacts on the upper power grid, among which the voltage boost and reverse power transmission of photovoltaics are the most prominent. First, the photovoltaic voltage boost may cause the voltage in the substation to be unstable, thereby increasing the difficulty of power grid management; secondly, the photovoltaic reverse power transmission may cause the substation to be reversely overloaded, reducing the life of the transformer and the reliability of power supply in the substation. The randomness, intermittency and volatility of distributed photovoltaics have an impact on the upper power grid, targeting the instability of the photovoltaic voltage boost on the substation voltage. When the output of distributed photovoltaics is too high, the substation voltage may exceed the safety value, resulting in damage to electrical equipment or shortening of its life.

[0069] Step S102: performing calculation processing based on the first operating parameter and a preset threshold coefficient to obtain a first upper limit control threshold and a first lower limit control threshold of the target substation;

[0072] In the specific implementation process of this step, when the reverse load rate exceeds the first upper limit regulation threshold by a number greater than the first quantity threshold within the first preset time period, the target area is in a reverse heavy overload state; when the reverse load rate is lower than the first lower limit regulation threshold by a number greater than the first quantity threshold within the first preset time period, the target area is in a reverse heavy overload recovery state; the first preset time period can be a time range of five minutes, one minute, etc., and the first preset time period can be set according to actual needs; the first quantity threshold can be set to 5, and the first quantity threshold can be set according to actual needs; the real-time user parameters include user type parameters, real-time user behavior change parameters, device status parameters, historical regulation record parameters, and) photovoltaic power generation and load The load level parameters include non-natural person user type, natural person user type and special user type; the real-time user behavior change parameters include drastic user behavior change type, medium user behavior change type and slight user behavior change type; the equipment status parameters include normal equipment status, healthy operation and abnormal equipment status, for example, when the inverter fails, the battery is overheated, etc., the equipment status is abnormal; the historical control record parameters include: the user was frequently controlled in the past, the user was occasionally controlled in the past and the user was rarely controlled in the past. When the user was frequently controlled in the past, the number of controls was greater than the average number of controls; when the user was occasionally controlled in the past, the number of controls was close to the average number of controls; when the user was rarely controlled in the past, the number of controls was less than the average number of controls. The photovoltaic power generation and load level parameters include: large power generation or high load, medium power generation or medium load and small power generation or low load. Specifically, users that account for more than 20% of the total load of the substation can be determined as having large power generation or high load; users that account for 10%-20% of the total load of the substation can be determined as having medium power generation or medium load; users that account for less than 10% of the total load of the substation can be determined as having small power generation or low load. Specifically, each of the distributed power users is scored based on the real-time user parameters of each distributed power user and different scoring dimensions to obtain a first scoring value of each different scoring dimension corresponding to the same distributed power user; calculations are performed based on each of the first scoring values ​​and the preset weight coefficients corresponding to each of the different scoring dimensions to obtain a second scoring value corresponding to the same distributed power user; each of the distributed power users is sorted based on each of the second scoring values ​​to obtain the control sequence.

[0073] Step S104: controlling the second operating parameter of each of the distributed power users based on the real-time dynamic priority of the regulation sequence.

[0074] In the specific implementation process of this step, when the number of times the reverse load rate exceeds the first upper limit control threshold within the first preset time period is greater than the first number threshold, a subtraction operation is performed based on the first upper limit control threshold and the preset redundancy value to obtain a first target load rate; a calculation is performed based on the first target load rate and the rated capacity of the target substation to obtain a first reverse apparent power of the target substation; a calculation is performed based on the first reverse apparent power and a predetermined power factor to obtain a first calculated active power value of the target substation; a subtraction operation is performed based on the real-time active power value of the target substation and the first calculated active power value to obtain a first target control value of the target substation; a calculation is performed based on the first target control value, the basic parameters of each distributed power user in the control sequence, and the second operating parameter to obtain a first control index value of the distributed power user used to control each distributed power user; and the second operating parameter of each distributed power user is controlled one by one in the order of the second score value from large to small based on each first control index value. When the number of reverse load rates lower than the first lower control threshold within the first preset time period is greater than the first number threshold, a subtraction operation is performed based on the first lower control threshold and the preset redundancy value to obtain a second target load rate; a calculation is performed based on the second target load rate and the rated capacity of the target substation to obtain a second reverse apparent power of the target substation; a calculation is performed based on the second reverse apparent power and a predetermined power factor to obtain a second calculated active power value of the target substation; a subtraction operation is performed based on the real-time active power value of the target substation and the second calculated active power value to obtain a second target control value of the target substation; a calculation is performed based on the second target control value, the basic parameters of each distributed power user in the control sequence, and the second operating parameter to obtain a second control index value for controlling each distributed power user; and the second operating parameter of each distributed power user is controlled one by one in the order of the second score value from small to large based on each second control index value.

[0075] This application aims to achieve the healthy development of new power systems, improve the stability, safety and control efficiency of power grids, and ensure the life of equipment and overall power supply reliability. This application comprehensively considers the internal information of the substation and the impact of distributed photovoltaics on the substation, selects transformer load rate and photovoltaic voltage value as key decision indicators for strategy output, comprehensively and in real time reflects the internal operation information of the substation, and then determines the substation control value, control method and control user. When a reverse heavy overload / photovoltaic voltage exceeds the limit is detected, the acquisition terminal will automatically generate a control strategy and perform real-time control through the communication module to achieve rapid response, prevent transformer overload, and ensure the life and reliability of the transformer and the entire power grid; relying on the resources of the power consumption information collection system, this solution can monitor and control low-voltage distributed photovoltaics in real time, realize fast and efficient power grid management, and improve the efficiency of power grid control. This application is applied to the edge side to relieve the control pressure of the main station; the control instructions at the substation layer have a higher priority than the user layer, ensuring the integrity and coordination of power grid management; the intelligent control method based on threshold adaptation and dynamic sequence can adapt to precise control in various scenarios to ensure stable control effect.

[0076] Another embodiment of the present application provides another method for controlling power grid operation parameters, such as Figure 2 As shown, including:

[0077] Step S201: performing calculation based on a first operating parameter of a target area and a rated capacity of the target area to obtain a reverse load rate of the target area;

[0078] In the specific implementation of this step, the first operating parameter may be the real-time reverse apparent power value S of the target station area. total , based on the first operating parameter and the rated capacity S n Perform division operation to obtain the reverse load rate P of the target area. load The mathematical expression of the reverse load rate can be expressed as follows:

[0079]

[0080] Among them, S total Indicates the reverse apparent power of the target area total meter; S n Indicates the rated capacity of the transformer in the substation; P load Indicates the reverse load ratio of the target area.

[0081] Step S202: performing calculation based on the first operating parameter and a preset threshold coefficient to obtain a first upper limit control threshold of the target substation;

[0082] In the specific implementation process of this step, first, the initial threshold is set; specifically, the historical operation data of the substation under different seasons and different load conditions are analyzed to determine the appropriate initial threshold. According to the characteristics of the substation transformer and distributed photovoltaic equipment: such as rated capacity, overload capacity, etc., the initial threshold is set to ensure that the system can operate normally under certain load fluctuations. Set the initial threshold according to the design specifications of the power grid operation. For the reverse heavy overload threshold: select a reasonable initial threshold based on historical data and system design parameters. For example, the initial reverse load rate threshold can be set to 80% based on the rated capacity of the substation transformer, that is, the maximum reverse power that the transformer can withstand is 80% of the rated capacity. For the voltage threshold: set the upper and lower voltage limits according to the standards of the power system and the tolerance of the equipment. For example, for a low-voltage distribution system with a nominal voltage of 220 volts, the voltage upper limit can be set to 1.05 times the nominal voltage, that is, 231 volts. Secondly, dynamically adjust the threshold; specifically, the system should dynamically adjust the threshold according to the actual situation. During high-load periods, in order to avoid frequent regulation and waste of resources, the threshold is appropriately increased; when temporary photovoltaic power generation is too high (such as during strong sunlight at noon), the threshold is increased to avoid frequent regulation due to short-term power generation peaks. When photovoltaic power generation drops suddenly (such as on cloudy days, sudden shading, etc.), in order to avoid voltage fluctuations caused by insufficient power generation, the threshold is lowered in advance to start regulation; when the power load drops suddenly (such as a sudden drop in load at night), the threshold is lowered to avoid voltage instability due to load fluctuations. The minimum step size for threshold adjustment is 5%. In addition, the present invention also considers redundancy strategies. When adjusting the threshold, a certain redundancy value is set to cope with unforeseen emergencies. The redundancy value can leave buffer time for system regulation to avoid frequent switching or excessive regulation. Specifically, a calculation is performed based on the first operating parameter to obtain a first mean μ1 and a first standard deviation σ1 of the first operating parameter; a mean calculation is performed based on the first operating parameter to obtain the first mean μ1 and a standard deviation calculation is performed based on the first operating parameter to obtain the first standard deviation σ1; a multiplication operation is performed based on the preset threshold coefficient and the first standard deviation to obtain a first product value k×σ1; a subtraction operation is performed based on the first mean and the first product value to obtain the first upper limit control threshold The first upper limit control threshold The mathematical expression of can be expressed as follows:

[0083]

[0084] The first lower limit regulation threshold is obtained by performing an addition operation based on the first mean value and the first product value. The mathematical formula for calculating can be shown as follows:

[0085]

[0086] Wherein, μ1 represents the first mean of the data; σ1 represents the first standard deviation of the data; k represents the preset threshold coefficient; the first upper limit control threshold of this application is For regulating the reverse heavy load, the first lower limit regulation threshold of the present application Used to regulate the recovery phase of reverse heavy loads.

[0087] Step S203: when the number of times the reverse load rate exceeds the first upper limit regulation threshold within the first preset time period is greater than the first number threshold, or the number of times the reverse load rate is lower than the first lower limit regulation threshold within the first preset time period is greater than the first number threshold, scoring each of the distributed power users based on the real-time user parameters and different scoring dimensions of each of the distributed power users to obtain first scoring values ​​of each different scoring dimension corresponding to the same distributed power user;

[0088] During the specific implementation of this step, when the reverse load rate exceeds the first upper control threshold in the first control threshold by a number greater than the first number threshold within the first preset time period, the operating state of the target substation is a reverse heavy overload state; the first number threshold can be 5, and the preset threshold can be set according to actual needs. When the reverse load rate is lower than the first lower control threshold by a number greater than the first number threshold within the first preset time period, the operating state of the target substation is a reverse heavy overload recovery state. The first upper control threshold and the first lower control threshold of the present application are updated in real time. Specifically, the first current operating parameter of the target substation at the current moment is obtained by real-time monitoring; the first upper control threshold and the first lower control threshold are updated in real time based on the first current operating parameter and the first historical operating parameter in the first preset time period before the current moment and the preset threshold coefficient. The same abnormal user is scored from different scoring dimensions to obtain the first scoring values ​​of different scoring dimensions corresponding to the same distributed power user; each different scoring dimension includes user type, real-time user behavior change, equipment status, historical control records, photovoltaic power generation and load level, etc. to score each abnormal user, wherein the calculation method of the first scoring value U of the user type is: non-natural person user (enterprise user): score = 3; natural person user (family user): score = 2; special user: score = 1, and the user type of the special user can be set according to actual needs. The calculation method of the first scoring value B of the real-time user behavior change is: user behavior changes drastically (for example, a sudden increase in power generation or a sudden change in load > 20%): score = 3; user behavior changes moderately (changes between 10%-20%): score = 2; user behavior changes slightly (changes < 10%): score = 1. The calculation method of the first scoring value D of the equipment status is: normal equipment status, healthy operation: score = 1; abnormal equipment status (for example, inverter failure, battery overheating, etc.): score = 3. The calculation method of the first score value H of the historical control record is: the user was frequently controlled in the past (the number of controls> the average number of controls): score = 1; the user was occasionally controlled in the past (the number of controls is close to the average number of controls): score = 2; the user was rarely controlled in the past (the number of controls < the average number of controls): score = 3. The calculation method of the first score value P of the photovoltaic power generation and load level is: large power generation or high load (such as more than 20% of the total load of the station): score = 3; medium power generation or medium load (such as 10%-20% of the total load of the station): score = 2; small power generation or low load (such as <10% of the total load of the station): score = 1.

[0089] Step S204: performing calculation based on each of the first scoring values ​​and the preset weight coefficients corresponding to the different scoring dimensions to obtain a second scoring value corresponding to the same distributed power user;

[0090] In the specific implementation process of this step, calculation processing is performed based on each of the first scoring values ​​and the preset weight coefficients corresponding to each of the different scoring dimensions to obtain a second scoring value S corresponding to the same distributed power user. The calculation mathematical formula of the second scoring value S of each user can be shown as the following formula (4):

[0091] S=W1*U+W2*B+W3*D+W4*H+W5*P(4)

[0092] Among them, S is the second scoring value of the priority corresponding to the abnormal user; W1 is the weight of each factor, indicating the relative importance of the factor in the priority calculation (the sum of weights W1+W2+W3+W4+W5=1); U is the user type score; B is the real-time user behavior change score; D is the device status score; H is the historical control record score; P is the photovoltaic power generation and load level score; the preset weight coefficients corresponding to the different scoring dimensions can be shown as W1-W5, and the weight setting W i Specifically, the user type weight W1 can be set to 0.1; the real-time user behavior change weight W2 can be set to 0.2; the device status weight W3 can be set to 0.3, the historical control record weight W4 can be set to 0.2, and the photovoltaic power generation and load level weight W5 can be set to 0.1. These weights can be adjusted according to actual conditions and system requirements. A higher priority score means that the user has a greater impact on the system, so the system may prioritize the control of this user to ensure the stability and operation efficiency of the power grid.

[0093] Step S205: sorting the distributed power users based on the second scoring values ​​to obtain a control sequence;

[0094] In the specific implementation of this step, a higher priority score means that the user has a greater impact on the system, so the system may give priority to regulating this user to ensure the stability and operating efficiency of the power grid. The dynamic priority adjustment mechanism can automatically adjust the user's regulation order according to the actual situation and data. The distributed power users are sorted based on each of the second scoring values ​​to obtain the regulation sequence. Specifically, the distributed power users can be sorted in order from high to low in terms of score value, or they can be sorted in order from low to high in terms of score value to generate the regulation sequence.

[0095] Step S206: controlling the second operating parameter of each of the distributed power users based on the real-time dynamic priority of the regulation sequence;

[0096] In the specific implementation process of this step, when the reverse load rate exceeds the first upper limit control threshold by more than the first number threshold within the first preset time period, a subtraction operation is performed based on the first upper limit control threshold and the preset redundancy value to obtain a first target load rate; a calculation is performed based on the first target load rate and the rated capacity of the target substation to obtain a first reverse apparent power of the target substation; a calculation is performed based on the first reverse apparent power and a predetermined power factor to obtain a first calculated active power value P of the target substation. need ; Based on the real-time active power value P of the target area actual And the first calculated active power value P need Subtraction operation is performed to obtain the first target control value of the target area; the calculation formula of the first target control value can be expressed as the following formula (5):

[0097] ΔP=P actual -P need (5)

[0098] Among them, ΔP is the first target control value. Based on the first target control value, the basic parameters of each distributed power user in the control sequence, and the second operating parameter, a calculation is performed to obtain the first control index value of the distributed power user used to control each distributed power user; specifically, the first control index value of the user is calculated according to the voltage-power curve relationship; the voltage sensitivity analysis can be performed according to the voltage and power curve of the user, and the correlation analysis can be performed to generate a voltage-power curve, that is, the power value corresponding to the voltage, based on which the data that the user should generate power (the current actual power generation data minus the data that needs to be reduced) can be determined, and then the specific control instructions can be further calculated according to the rated power. Based on each of the first control index values, the second operating parameters of each distributed power user are regulated one by one in the order of the second score value from large to small. When the target area is in the reverse heavy overload control stage, the sorted control sequence is traversed to determine the rigid and flexible category of the current user. If it is a rigid user, the user is cut off; if it is a flexible user, the power factor is dynamically adjusted, and the active power percentage is gradually reduced as needed. When executing the control, the system will update the user's status and operation records in real time to ensure that each round of control is based on the latest data. If the power factor and active percentage of the flexible user have been adjusted to the lower limit, the control instruction of the current user is stored, and the abnormal user sequence is continued to be traversed until the calculation result shows that the total table of the target area no longer has a reverse heavy overload. The second operating parameters of the distributed power users are controlled one by one based on the second scoring values ​​of each distributed power user in the regulation sequence from high to low; the second operating parameter can be a voltage value, and the target area is adjusted according to the first target regulation value by adjusting the second operating parameter of each distributed power user, and the current first operating parameter is reduced to below the first regulation upper limit. Voltage is one of the core indicators of power quality and grid stability. Distributed photovoltaic power generation may cause local voltage fluctuations or abnormal increases (voltage over-limit) due to its randomness, intermittency and volatility. By monitoring the voltage value of photovoltaic users, voltage abnormalities caused by photovoltaic power generation can be detected and responded to in a timely manner to ensure the safe operation of the power grid. An increase in photovoltaic power generation will cause voltage to rise, while a sudden drop in power generation may cause voltage to drop. Especially in scenarios with low power load or long transmission lines, voltage fluctuations caused by photovoltaic power generation are more obvious. Therefore, by monitoring the voltage value of photovoltaic power generation, the impact of photovoltaic power generation on the power grid can be directly reflected, and regulatory measures can be taken in a timely manner. When voltage abnormalities occur in the power grid, monitoring the voltage values ​​of each photovoltaic user can help quickly locate the source of the problem. By detecting the voltage point by point, it is possible to determine which photovoltaic user or users caused the voltage fluctuation, so that regulatory measures can be taken more accurately.By monitoring the voltage values ​​of PV users, the power grid can better understand the actual impact of PV power generation on the power grid, quickly identify and locate problems, implement efficient control strategies, and ensure the safety of equipment and users. This makes the voltage value a key monitoring indicator that helps maintain the stability and operating efficiency of the power grid. Finally, the system will issue all stored control instructions to complete the control task; the system dynamically adjusts the priority of PV users based on the latest data and updates the sorting rules in real time. This update process will continue to reflect the latest user behavior and equipment status, thereby optimizing the control effect. Throughout the control process, the system continuously evaluates and optimizes the priority sorting to ensure the fairness of resource allocation and maximize benefits.

[0099] When the number of the reverse load rate lower than the first lower limit control threshold in the first preset time period is greater than the first number threshold, a subtraction operation is performed based on the first lower limit control threshold and the preset redundancy value to obtain a second target load rate; a calculation is performed based on the second target load rate and the rated capacity of the target area to obtain a second reverse apparent power of the target area; a calculation is performed based on the second reverse apparent power and the predetermined power factor to obtain a second calculated active power value of the target area; a subtraction operation is performed based on the real-time active power value of the target area and the second calculated active power value to obtain a second target control value of the target area; a calculation is performed based on the second target control value, the basic parameters of each distributed power user in the control sequence, and the second operating parameter to obtain a second control index value for controlling each distributed power user; and the second operating parameter of each distributed power user is controlled one by one in the order of the second score value from small to large based on each second control index value. The second operating parameter may be a voltage value, and the target area is adjusted according to the second target control value by adjusting the second operating parameter of each distributed power user, so that the current first operating parameter is increased to above the first control lower limit.

[0100] Step S207: performing calculation processing based on the current operating parameter value of the distributed power user within the second preset time period to obtain a second mean value and a second standard deviation corresponding to the distributed power user;

[0101] During the specific implementation of this step, the current operating parameter value of the distributed power user is the voltage value data acquired in real time, and the mean calculation is performed on the voltage value data within the second preset time period to obtain the second mean value μ2; the standard deviation calculation is performed on the voltage value data within the second preset time period to obtain the second standard deviation σ2.

[0102] Step S208: performing a multiplication operation based on the preset threshold coefficient and the second standard deviation to obtain a second product value;

[0103] In the specific implementation process of this step, a multiplication operation is performed based on the preset threshold coefficient and the second standard deviation to obtain a second product value k×σ2.

[0104] Step S209: performing a subtraction operation based on the second mean value and the second product value to obtain a second control upper limit threshold;

[0105] In the specific implementation process of this step, a subtraction operation is performed based on the second mean value and the second product value to obtain the second control upper limit threshold value. The second regulation upper limit threshold The mathematical expression of can be shown as follows:

[0106]

[0107] Wherein, μ2 represents the second mean of the data; σ2 represents the second standard deviation of the data; and k represents the preset threshold coefficient.

[0108] Step S210: performing an addition operation based on the second mean value and the second product value to obtain a second control lower limit threshold;

[0109] In the specific implementation process of this step, an addition operation is performed based on the second mean value and the second product value to obtain the second lower limit regulation threshold. The mathematical formula for calculating can be shown as follows:

[0110]

[0111] The second upper limit control threshold of this application Used to regulate the voltage value of the distributed power user when it exceeds the second upper limit regulation threshold, the second lower limit regulation threshold of this application Used to regulate the voltage value of distributed power users that is lower than the second lower limit regulation threshold.

[0112] Step S211: when the current operating parameter value of the distributed power user is greater than the second regulation upper limit threshold or the current operating parameter value of the distributed power user is less than the second regulation lower limit threshold, a third regulation index value corresponding to the distributed power user is obtained by performing calculation based on the current operating parameter value of the distributed power user, the second regulation upper limit threshold or the second regulation lower limit threshold, and the rated power value;

[0113] In the specific implementation process of this step, when the current operating parameter value of the distributed power user is greater than the second regulation upper limit threshold or the current operating parameter value of the distributed power user is less than the second regulation lower limit threshold, the third regulation index value corresponding to the distributed power user is obtained based on the current operating parameter value of the distributed power user, the second regulation upper limit threshold or the second regulation lower limit threshold, and the rated power value. Specifically, the control value of the user is calculated according to the voltage-power curve relationship; the voltage sensitivity analysis and correlation analysis can be performed according to the voltage and power curves of the user, and a voltage-power curve can be generated, that is, the corresponding power value is obtained through the voltage value, based on which the data that the user should generate electricity (the current actual power generation data minus the data that needs to be reduced) can be determined, and then the specific control instructions are further calculated according to the rated power to obtain the third control index value corresponding to the distributed power user.

[0114] Step S212: regulating the current operating parameter value of the distributed power source user based on the third regulation index value.

[0115] During the specific implementation of this step, when no reverse heavy overload occurs and no reverse heavy overload is recovered within the first preset time period, the current operating parameter value of the distributed power user is regulated based on the third control index value; when the number by which the reverse load rate exceeds the first upper limit control threshold within the first preset time period is greater than the first number threshold, the current operating parameter value of the target distributed power user is greater than the second control upper limit threshold, and the target distributed power user is included in the control sequence, the first control index value and the third control index value corresponding to the target distributed power user are compared to obtain a comparison result; when the comparison result is that the first control index value is greater than or equal to the third control index value, the current operating parameter value of the target distributed power user is regulated based on the third control index value; when the comparison result is that the first control index value is less than the third control index value, the current operating parameter value of the target distributed power user is regulated based on the first control index value. When the number by which the reverse load rate exceeds the first upper control threshold within the first preset time period is greater than the first number threshold, the current operating parameter value of the target distributed power user is greater than the second control upper limit threshold, and the target distributed power user is included in the control sequence, the current operating parameter value of the target distributed power user is regulated based on the smaller indicator value between the third control index value and the first control index value.

This application comprehensively considers the internal information of the substation and the impact of distributed photovoltaics on the substation, selects the transformer reverse load rate and photovoltaic voltage value as the key decision indicators of the strategy output, comprehensively and in real time reflects the internal operation information of the substation, and then determines the substation control value, control method and control user. When it is detected that the target substation is in the reverse heavy overload stage or the photovoltaic voltage exceeds the limit, the voltage value of each distributed power user is automatically regulated to ensure the life and reliability of the transformer and the entire power grid; relying on the resources of the power consumption information collection system, this application can monitor and control low-voltage distributed photovoltaics in real time, realize fast and efficient power grid management, and improve the power grid control efficiency. The solution is applied to the edge side, which can alleviate the control pressure of the main station; the control instructions of the target substation have a higher priority than the distributed power users, ensuring the integrity and coordination of power grid management; intelligent control based on real-time updated threshold adaptation and dynamic priority user sequence can adapt to precise control in various scenarios and ensure stable control effect.
