Description

Technical Field

[0001] This application relates to the field of power technology, and in particular to a method and related device for dynamic power consumption regulation. Background Technology

[0002] Affected by factors such as primary energy supply and fuel prices, the national generating capacity is limited, resulting in a tight power supply situation. Provinces across the country have activated their orderly power consumption plans, with many industrial enterprises implementing staggered power usage, such as "three days on, four days off" or even "two days on, five days off." Data shows that from January to August 2021, Guangdong Province's total electricity consumption reached 525.273 billion kilowatt-hours, a year-on-year increase of 17.33%. Since September 2021, the combination of a healthy economy, high electricity demand, and high temperatures has led to Guangdong's peak load demand exceeding 141 million kilowatts in September, a year-on-year increase of 11%. This round of staggered power usage is mainly due to factors such as the double increase in electricity demand under high temperatures and the limited generating capacity of units within the province.

[0003] As a legal metering instrument for electricity consumption in smart grids, smart meters support multi-rate metering functions, but they cannot dynamically adjust electricity rates in real time for special circumstances such as high temperatures, thus failing to achieve the effect of peak shaving and valley filling, and further guide orderly electricity consumption.

[0008] S3. Analyze whether to update the daily time slot table of the module based on the total number of programming times, the time slot table, and the content of the time slot table stored in the communication module.

During operation, when a change rate period parameter is received, the total number of programming times for the rate parameter table is set according to the encryption method type of the change rate period parameter; the received high-temperature rate electricity price period data is saved; when a high-temperature electricity rate period table switching command is received, the operation of the electricity meter is controlled according to the high-temperature rate electricity price period data.

[0010] Optionally, the conversion of the rate time period table based on the daily time period table of the second rate time period table switching time specifically includes:

[0011] After converting the rate time period table according to the daily time period table of the second set of rate time period table switching time, the rate time period table is marked and the total number of rate parameter programming times is updated.

[0012] Optionally, step S3 includes:

[0013] If the total number of rate parameter programming times saved by the communication module is the same as that of the base table, different from the first set of rate time period tables of the base table, and the content is the same as that of the second set of rate time period tables of the base table, and the second set of rate time period tables is in effect, then the daily time period table saved by the communication module will not be updated.

[0014] Optionally, step S3 includes:

[0015] If the total number of rate parameter programming times saved by the communication module is the same as that of the base table, the same as the first set of rate time period tables of the base table, and the switching time of the second set of rate time period tables has not yet arrived, then the daily time period table saved by the communication module will not be updated.

[0016] Optionally, step S3 includes:

[0017] If the total number of rate parameter programming attempts stored in the communication module is the same as the total number of attempts in the base table, then the daily time slot table stored in the communication module will not be updated.

[0018] A second aspect of this application provides a method for dynamic electricity consumption regulation, applied to an electricity meter, the method comprising:

[0019] During operation, it receives and saves high-temperature electricity rate and price data for specific time periods from the main station;

[0020] When a switching command for the high-temperature electricity rate time period table is received from the main station, the electricity meter is controlled to operate according to the high-temperature electricity rate time period data.

[0021] A third aspect of this application provides a dynamic power regulation device, the device comprising a processor and a memory:

[0022] The memory is used to store program code and transmit the program code to the processor;

[0023] The processor is configured to execute the steps of the power dynamic adjustment method as described in the first or second aspect above, according to the instructions in the program code.

[0024] A fourth aspect of this application provides a computer-readable storage medium for storing program code for executing the power dynamic adjustment method described in the first or second aspect above.

[0027] Compared with existing technologies, the dynamic electricity consumption adjustment method of this application can achieve flexible tariff pricing simply by upgrading the existing communication module of the electricity meter or designing a new communication module, and the modification cost is very low. Furthermore, by designing a new electricity meter using the dynamic electricity consumption adjustment method provided in the second aspect above, flexible tariff time-of-use pricing can be implemented. This solves the technical problem that existing technologies only support switching during normal times and do not support flexible tariff time-of-use functions such as weather-based pricing.

[0030] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present application.

[0031] It should be noted that the design process for traditional smart energy meter rate periods is as follows:

[0032] 1. At least four rates are supported: peak, flat, and off-peak.

[0033] 2. It has two sets of rates and time periods that can be programmed arbitrarily, and the other set of rates and time periods can be activated at a set time.

[0034] 3. Each rate period can have at least 2 time zones set throughout the year; and at least 8 time periods can be set within 24 hours.

[0035] 4. The maximum number of time zones per year is 14, and each time period table can contain a maximum of 8 daily time periods, with a maximum of 14 daily time periods.

[0036] 5. Supports switching between two time zones and two daily time schedules.

[0037] 6. Supports setting special rate periods for public holidays and weekends.

[0038] 7. The order of public holidays and weekend time zones will be used as the priority for querying the current day's time period table.

[0039] It should be noted that in this embodiment, the master station issues the handover command via broadcast, as detailed below:

[0040] Master station request frame:

[0041] Function: The master station sends a command to the slave station to switch the high-temperature electricity rate time period table.

[0042] Control code: C=10H

[0043] Data field length: L = 0.5H

[0044] The frame format is as follows:

[0045] 68H A0 … A5 68H 10H 05H DD MM YY NN dd CS 16H day moon Year Daytime Time Table Number Days

[0046] [Special Note]:

[0047] (1) If this command is broadcast, no response is required.

[0048] (2) This command does not require the use of programming keys.

[0049] (3) The maximum duration is 99 days. If dd = 255, the duration will continue until the next timetable switch time. If the daily timetable switch time is earlier than the duration dd, the daily timetable switch takes priority.

[0052] Data field length: L = 00H

[0053] The frame format is as follows:

[0056] Control code: D0H

[0057] Data field length: L = 01H

[0058] The frame format is as follows:

[0059] 68H A0 … A5 68H D0H 01H ERR CS 16H

[0060] [Note]: To support unified settings for multiple tables, this command can be broadcast. Broadcast commands do not require a response.

[0061] Please see Figure 1 The first embodiment of this application provides a method for dynamic power consumption adjustment, comprising:

[0062] Step 101: When powered on, determine whether the local E2PROM module has a daily time period table. If yes, proceed to step 103; otherwise, proceed to step 102.

[0063] It should be noted that E2PROM generally refers to EEPROM. EEPROM (Electrically Erasable Programmable Read-Only Memory) is a type of memory chip that retains data even when power is off. EEPROM can be erased and reprogrammed on a computer or dedicated device. It is typically used in plug-and-play applications.

[0064] Understandably, when the communication module is powered on, it first checks whether the local E2PROM already has a day / time period table. If it does, it proceeds to step 103; otherwise, it proceeds to step 102.

[0065] Step 102: Obtain the switching time of the second set of rate time period tables from the base table, and convert the rate time period tables according to the daily time period tables of the second set of rate time period tables;

[0066] It should be noted that if the E2PROM module does not save the daily time period table, it will first check the switching time of the second set of rate time period tables in the base table, obtain the daily time period table within the validity period from the base table, and automatically complete the rate time period table conversion. When the module saves the rate time period table, it should set a save flag: Flag=97H, and save the "total number of times the rate parameter table is copied" locally, recalculate the checksum, and use the newly saved daily time period table as the standard.

[0067] Step 103: Analyze whether to update the daily time slot table of the module based on the total number of programming attempts, the time slot table, and the content of the time slot table stored in the communication module.

[0068] In this embodiment, the daily time slot table of the communication mode will not be updated in the following three cases:

[0069] 1. If the E2PROM module has a saved daily time period table, and the "total number of rate parameter programming times" saved by the communication module is the same as the "total number of rate parameter table programming times" obtained from the base table; but the current set (first set) in the module is different from the current set rate time period table in the base table, but the content is the same as the second set rate time period table in the base table, and the second set rate time period table is in effect, then the daily time period table of the communication module itself shall prevail (when the module is replaced, this time period table shall not be cleared).

[0070] 2. If the E2PROM module has a saved daily time period table (the checksum of the time period table in the module is correct, and Flag = 97H), when the "total number of rate parameter programming times" saved by the communication module is the same as the "total number of rate parameter table programming times" obtained from the base table; and the current rate time period table of the module is the same as the current set (first set) of the base table, and the switching time of the second set of rate time period table has not yet arrived, then the module's own daily time period table shall prevail (when the module is replaced, the time period table shall not be cleared).

[0071] 3. If the E2PROM module has a saved daily time period table (the checksum of the time period table in the module is correct, and Flag = 91H), when the "total number of rate parameter programming times" saved by the communication module is the same as the "total number of rate parameter table programming times" obtained from the base table; regardless of whether the current rate time period table of the communication module is the same as the current set (first set) and the standby set (second set) of the base table (the base table running status word should be queried first to see if rate time period table programming has occurred), the daily time period table of the communication module itself shall prevail. When it is necessary to switch rate sets, the locally saved rate parameters shall also prevail (when the module is replaced, the time period table shall not be cleared).

[0072] Step 104: During operation, when a change rate period parameter is received, the total number of programming times for the rate parameter table is set according to the encryption method type of the change rate period parameter; the received high-temperature rate electricity price period data is saved; when a high-temperature electricity rate period table switching command is received, the operation of the electricity meter is controlled according to the high-temperature rate electricity price period data.

[0073] It should be noted that during the operation of the communication module, when it detects changes to rate period-related parameters via encryption methods C=14H, PA=97H or 99H (encryption method 1), the communication module should first forward the command to the base table, and then reread the "Total Number of Rate Parameter Table Programming Counts" in the base table after 30 minutes. If the total number of rate programming counts saved by the module is less than the total number saved by the base table, refer to steps 101-103 to update the rate period table in the module. When it detects changes to rate period-related parameters via encryption methods C=14H, PA=91H (encryption method 2), only the local rate period table is updated; the relevant command does not need to be sent to the base table, and the "Total Number of Rate Parameter Programming Counts" in the communication module remains unchanged, but FLAG=91H is recorded.

[0074] Furthermore, the received high-temperature rate electricity price period data is saved, and when a high-temperature rate electricity price period table switching command is received, the high-temperature rate electricity price function is enabled and disabled according to the agreed time.

[0078] Step 202: When the switch command for the high-temperature electricity rate time period table is received from the main station, the electricity meter is controlled to work according to the high-temperature electricity rate time period data.
