Embodiments of the application are described in further detail below with reference to the drawings.

The embodiment of the application provides a coordinated peak shaving method based on power grid conveying capacity and power grid safety, which is executed by electronic equipment, wherein the electronic equipment can be a server or terminal equipment, and the server can be an independent physical server, a server cluster or a distributed system formed by a plurality of physical servers, or a cloud server for providing cloud computing service. The terminal device may be, but is not limited to, a smart phone, a tablet computer, a notebook computer, a desktop computer, etc., and the terminal device and the server may be directly or indirectly connected through wired or wireless communication, which is not limited herein, and as shown in fig. 1, the method includes step S101, step S102, step S103, step S104, step S105, and step S106, where,

Step S101, judging whether the current time of the area reaches the preset time.

The preset time is the initial time of any electricity utilization peak time.

For the embodiment of the application, the clock chip is arranged in the electronic equipment so as to obtain the current time of the area, and the current time can be obtained through the internet and the cloud server, which is not limited herein. The electronic device determines whether the current time reaches an initial time of any electricity peak period. For example: assume that the peak electricity consumption period in a day is:

10:00-15:00 and 18:00-21:00;

if the current time is 10:00 or 18:00, then indicates that the preset time is reached, 10:00 or 18: after 00, the peak power value of electricity consumption may continue to increase.

Step S102, if the current time reaches the preset time, a first electric power value is obtained.

The first electric power value is the electric power value corresponding to the current moment.

For the embodiment of the present application, assume that the current time is 18:00, electronic device acquisition 18: the power consumption value corresponding to 00 is 900KW, and 18:00 to facilitate calculation of the peak power rate of increase in the peak power of electricity in the peak period of electricity usage from 18:00 to 21:00.

Step S103, obtaining a second power consumption value.

For the embodiment of the present application, taking step S102 as an example, if the electronic device acquires the current time 18:00, assuming that the preset time is 1/60h (1 min), the electronic device obtains 18:01 and the power consumption is 1500KW. By acquiring acquisition 18:01 to facilitate calculation of the current peak power growth rate for electricity consumption in the peak electricity consumption period of 18:00-21:00.

Step S104, calculating the power consumption peak power increase speed based on the first power consumption value, the second power consumption value and the preset time.

For the embodiment of the application, taking step S102 and step S103 as examples, the electronic device calculates the peak power increase rate of electricity consumption:

peak power increase rate of electricity consumption= (1500-900)/(1/60=36000 KW/h;

indicating a 36000KW increase per hour in peak power consumption values during peak power consumption periods of 18:00-21:00.

Step S105, determining a required peak shaver set based on the power consumption peak power increase speed.

The required peak shaver set comprises a hydroelectric generating set and a thermal generating set.

For the embodiment of the application, the electronic equipment determines the required peak shaver set based on the power consumption peak power increasing speed, and the starting speed of the hydroelectric generator set is faster than that of the thermal generator set. The hydroelectric generating set can finish starting and power supply within 0.05h (3 min), but the power supply of the hydroelectric generating set is easily influenced by weather and climate. For the thermal power generating unit, the operation such as boiler preheating is needed to be carried out for 1/3h (20 min) before the thermal power generating unit is started, the starting time is longer than 1/6h (10 min), and the power supply of the thermal power generating unit is not influenced by weather and climate. Therefore, the hydraulic generator set is selected to supply power more timely, and the thermal generator set is selected to supply power more stably. And the electronic equipment supplies power by selecting a proper peak shaver set, so that the condition that the power grid enters overload is reduced.

And S106, if the peak power value of the electricity consumption reaches the load power value, controlling the required peak shaver set to supply power to the area.

For the embodiment of the application, assuming that the load power value is 9000KW, if the power consumption peak power value reaches 9000KW, the electronic equipment controls the required peak shaver set to supply power to the area. For example:

assuming that the current moment is 19:30 and the corresponding electricity consumption peak power value is 9000KW, the load power value 9000KW is reached, and the required peak shaver set is controlled to supply power to the area, so that the situation that the electricity consumption peak power value at 19:31 is larger than the load power value and overload of the power grid occurs is reduced.

One possible implementation manner of the embodiment of the present application, in step S105, the required peak shaver set is determined based on the increasing speed of the peak power of electricity consumption, which specifically includes step S1051 (not shown in the figure), step S1052 (not shown in the figure), step S1053 (not shown in the figure), and step S1054 (not shown in the figure), wherein,

step S1051 calculates a power increase time based on the peak power increase rate of electricity consumption.

Wherein the power increase time is the time required for the first electric power value to increase to the load power value.

For the embodiment of the present application, taking step S106 as an example, if the power consumption peak power increase speed in the power consumption peak period of 18:00-21:00 is 36000KW/h, and 18: the power consumption peak power value of 00 is 900KW, and the power increasing time from 900KW to 9000KW is calculated:

Power rise time= (9000-900)/(36000=0.225 h;

illustrating that the peak power usage value reaches the load power value when 18:13 in the peak power usage period of 18:00-21:00.

If the power increase rate of the electricity consumption peak in the electricity consumption peak period of 18:00-21:00 is 6000KW/h, and 18: the power consumption peak power value of 00 is 900KW, and the power increasing time from 900KW to 9000KW is calculated:

power increase time= (9000-900)/(6000=1.35 h;

illustrating that the peak power usage value reaches the load power value when 19:21 in the peak power usage period of 18:00-21:00.

The faster the peak power rate of electricity consumption increases, the shorter the power increase time, and thus the shorter the time to reach the load power value.

Step S1052, determine whether the power increase time is less than a preset increase time.

For the embodiment of the present application, it is assumed that the preset increase time is 0.3h (18 min), and taking step S1051 as an example, when the peak power increase speed of electricity consumption is 36000KW/h, the power increase time is 0.225h (13.5 min), which is smaller than the preset increase time is 0.3h (18 min). When the power consumption peak power increasing speed is 6000KW/h, the power increasing time is 1.35h (81 min) and is not less than the preset increasing time of 0.3h (18 min). The electronic equipment selects the peak shaver set by judging whether the peak shaver set is smaller than the preset increasing time, and can timely supply power to the area after the peak shaver set passes the power increasing time by selecting the proper peak shaver set, so that the phenomenon of overload of the power grid is reduced.

In step S1053, if the power increase time is less than the preset increase time, the hydro-generator set is selected.

For the embodiment of the application, taking step S1052 as an example, the power increasing time is 0.225h (13.5 min) which is less than the preset increasing time of 0.3h (18 min), because the hydroelectric generator is started quickly, the hydroelectric generator can be started within 0.05h (3 min) and is less than the preset increasing time, and when the peak power value of electricity consumption reaches the load power value, the starting can be completed within 0.225h (13.5 min) to supply electricity in time; however, the operation of boiler preheating and the like is required to be carried out for 1/3h (20 min) before the thermal generator set is started, the starting time is 1/6h (10 min), the preparation time and the starting time of the thermal generator set are longer than the preset increasing time of 0.3h (18 min), and the power supply cannot be completed within 0.225h (13.5 min), so that the hydraulic generator set is selected for peak shaving during peak shaving. The hydroelectric generating set is selected to supply power more timely, so that overload of the power grid is reduced to a great extent.

In step S1054, if the growth time is not less than the preset growth time, a thermal generator set is selected.

For the embodiment of the application, taking step S1052 as an example, the power increasing time is 1.35h (81 min), which is not less than the preset increasing time is 0.3h (18 min), because the thermal generator set can complete starting and power supply within 1.35h (81 min), and compared with the hydroelectric generator set, the thermal generator set is not easily influenced by weather and climate, so the thermal generator set is selected to supply power more stably.

One possible implementation manner of the embodiment of the present application, the method further includes step S107 (not shown in the figure), step S108 (not shown in the figure), step S109 (not shown in the figure), step 110 (not shown in the figure), and step S111 (not shown in the figure), and step S107 may be performed after step S101, where,

step S107, if the current moment is not in any electricity peak time, a third electricity power value is obtained.

And the third electric power value is the electric power value corresponding to the current moment in the electric level peak period.

For the embodiment of the application, assuming that the peak period of the power consumption level is 7:00-10:00, 15:00-18:00 and 21:00-24:00, if the current time is 9:00, obtaining the power consumption value corresponding to 9:00 as 850KW in the peak period of the power consumption level, and obtaining 9:00 to facilitate calculation of the power up rate of the power up level in the peak period of the power up level in the range of 7:00-10:00.

Step S108, a fourth power consumption value is obtained.

The fourth power consumption value is the power consumption value after the preset time passes after the third power consumption value is obtained.

For the embodiment of the present application, taking step S107 as an example, if the electronic device acquires the current time 9:00, assuming that the preset time is 1/60h (1 min), the electronic device obtains 9:01 and 1000KW. Acquisition 9 by acquisition: 01 to facilitate calculation of the peak power growth rate of electricity consumption in the peak electricity consumption period of 7:00-10:00.

Step S109, calculating a power increase rate of the peak power of the power level for use based on the third power value, the fourth power value, and the preset time.

For the embodiment of the present application, taking step S107 and step S108 as examples, the electronic device calculates the level peak power increase rate for use:

peak power increase rate with level= (1000-850)/(1/60=9000 KW/h;

indicating a 9000KW increase per hour in the peak power level value of the power level in the peak period of power level of 7:00 to 10:00.

Step S110, judging whether the power increasing speed of the peak power of the level is larger than a preset increasing speed.

For the embodiment of the application, taking step S109 as an example, assuming that the preset increasing speed is 3000KW/h, the increasing speed 9000KW/h of the power consumption level peak power is greater than the preset increasing speed 3000KW/h, which indicates that the increasing speed of the power consumption level peak power is suddenly increased in the period of the power consumption level peak.

In step S111, if the increase speed of the power consumption level peak is greater than the preset increase speed, it is determined that the power of the power consumption level peak is abnormal.

For the embodiment of the application, taking step S110 as an example, if the increase speed 9000KW/h of the power level peak is greater than the preset increase speed 3000KW/h, it indicates that the power level peak is abnormal, the power level peak power value may be fluctuated repeatedly, or the power level peak power value may be fluctuated in a short time.

In one possible implementation manner of the embodiment of the present application, the method further includes step S112 (not shown in the figure) and step S113 (not shown in the figure), and step S112 may be performed after step S111, where,

step S112, judging whether the peak power value of the level reaches the load power value.

For the embodiment of the present application, assuming that the peak power value of the level is 9000KW, the load power value 9000KW is reached. The peak power value of the level is used to reach the load power value, so that the condition that the peak power value of the level is suddenly increased is determined.

Step S113, if the power value of the level peak reaches the load power value, a power supply signal is sent to the energy storage system, so that the energy storage system supplies power to the area.

For the embodiment of the application, assuming that the peak power value of the level is 9000KW and reaches the load power value of 9000KW, a power supply signal is sent to the energy storage system so that the energy storage system supplies power to the area, wherein the energy storage system can be a high-energy battery or other energy storage systems. The energy storage system collects and stores the temporarily unused surplus electric quantity, and the energy storage system is selected to supply power more conveniently and rapidly, so that the overload condition of the power grid is effectively reduced, and the damage to the power grid or electronic equipment caused by sudden increase of the peak power value of the power level is reduced.

One possible implementation manner of the embodiment of the present application, the method further includes step S114 (not shown in the figure), step S115 (not shown in the figure), step S116 (not shown in the figure), step S117 (not shown in the figure), and step S118 (not shown in the figure), and step S114 may be performed before step S106, where,

step S114, the historical call set number of at least two of the areas is obtained.

The historical call unit number is the number of call peak shaving units corresponding to any electricity peak time.

For the embodiment of the application, the electronic device can acquire the historical call set number of the area from the database, and can also acquire the historical call set number from the cloud server, which is not limited herein. For example:

the electronic equipment acquires 3 historical call unit numbers from the database:

the number of historical call units in 2018 is 50;

the number of historical call units in 2019 is 70;

the number of historical call units in 2020 is 90.

By obtaining the history of the number of call sets, the number of sets required in 2021 can be predicted.

Step S115, calculating the required unit number based on the history calling unit number.

For the embodiment of the application, taking step S114 as an example, the number of units required for 2021 is 110 if the number of units to be called per year is 20, so that the number of units required for peak shaving in 2021 is effectively predicted.

And S116, judging whether the number of the needed units is larger than the total number of the peak shaver units.

For the embodiment of the application, the total number of peak shaver sets in 2021 is 105, and the number of required sets is 110 and is larger than the total number of peak shaver sets by 105, which indicates that when the power consumption peak power value reaches the load power value, the phenomenon that overload of the power grid can not be reduced by only carrying out peak shaver through the peak shaver sets. If the total number of peak shaver sets in 2021 is 115, the number of required sets is not more than 110 and is not more than 115, which means that when the peak power value of electricity reaches the load power value, the phenomenon of overload of the power grid can be reduced by only carrying out peak shaver through the peak shaver sets.

And S117, if the number of the needed units is larger than the total number of the peak shaving units, determining the regional power grid to be accessed.

For the embodiment of the application, if the number of the needed units is 110 and is larger than 105, the phenomenon that overload of the power grid can not be reduced by carrying out peak regulation only through the peak regulation unit when the power consumption peak power value reaches the load power value is indicated, and the electronic equipment is required to determine the power grid to be connected into the area so as to supply power, so that the overload of the power grid is reduced.

And step S118, controlling the regional power grid to be accessed to supply power to the regional.

For the embodiment of the application, after the electronic equipment determines the regional power grid to be accessed, when the number of the needed units is larger than the total number of the peak shaving units and the power consumption peak power value reaches the load power value, the regional power grid to be accessed is controlled to supply power to the regional power grid, so that the phenomenon of overload of the power grid is reduced.

In one possible implementation manner of the embodiment of the present application, the determining the to-be-accessed regional power grid in step S117 specifically includes step S1171 (not shown in the figure), step S1172 (not shown in the figure), step S1173 (not shown in the figure), and step S1174 (not shown in the figure), where,

step S1171, obtaining the historical power supply state of at least one regional power grid and the position information of at least one regional power grid in a preset range.

Wherein the historical power supply state includes an overload state and a non-overload state.

For the embodiment of the application, the preset range may be a circular range with a radius of 500km with the current regional power grid as the center, a square range with a diagonal length of 1000km with the current regional power grid as the center, or other types of preset ranges, which are not limited herein. The electronic device may obtain the historical power supply state and the location information of at least one regional power grid within a preset range from the database, or may also obtain the historical power supply state and the location information from the cloud server, which is not limited herein. For example:

The electronic equipment acquires historical power supply states and position information of all regional power grids in a circular range with the radius of 500km by taking the central position of a current regional power grid as a circle center from a database, and establishes a rectangular coordinate system by taking the current regional power grid as an origin, so that the position information of the regional power grids in a preset range is acquired, and 5 regional power grids are assumed to be acquired in the preset range:

regional power grid 1: the historical power supply state is 10 times of non-overload, 2 times of overload, and the position information is (100, 400);

regional power grid 2: the historical power supply state is 12 times of non-overload, 0 times of overload, and the position information is (200 );

regional power grid 3: the historical power supply state is 9 times of non-overload, 3 times of overload, and the position information is (200, 300);

regional power grid 4: the historical power supply state is 12 times of non-overload, 0 times of overload, and the position information is (100, 200);

regional power grid 5: the historical power supply state is 10 times of non-overload, 0 times of overload, and the position information is (300, 100).

By acquiring the historical power supply state and the position information of at least one regional power grid in a preset range, the regional power grid which is most suitable for supplying power to the current regional power grid is selected, so that the power supply is more convenient and rapid.

Step S1172, at least one adjustable electricity regional grid is determined.

The at least one adjustable power regional power grid comprises power grids with historical power supply states which are all in non-overload states.

For the embodiment of the present application, the regional power grids with no overload state in the historical power supply states are determined as the adjustable power regional power grids, and taking step S1171 as an example, the adjustable power regional power grids include the regional power grid 2, the regional power grid 4 and the regional power grid 4. The historical power supply states are all non-overload states, so that the possibility of overload states of the adjustable power grid is low, and the adjustable power grid can be adjusted.

In step S1173, a power adjustment distance of the at least one power adjustable regional power grid is calculated.

The power adjustment distance is the distance between the power adjustable regional power grid and the current regional power grid.

For the embodiment of the present application, taking step S1171 and step S1172 as examples, the distance between the adjustable power regional power grid is the distance between the adjustable power regional power grid and the origin in the rectangular coordinate system, and the power adjustment distances of all the adjustable power regional power grids are calculated according to the pythagorean theorem:

power adjustment distance of regional power grid 2 =

Power adjustment distance of regional power grid 4 =

The tuning distance of the regional power grid 5 =/>

The maximum power adjustment distance of the regional power grid 5 and the minimum power adjustment distance of the regional power grid 4 can be obtained.

The distance between the adjustable power regional power grid and the current power grid can be intuitively seen by calculating the power adjustment distance, so that a proper adjustable power regional power grid is selected for power adjustment.

Step S1174, determining the regional power grid to be accessed based on the power adjustment distance.

The regional power grid to be accessed is the regional power grid corresponding to the minimum value in the power adjustment distance.

For the embodiment of the present application, the electronic device determines that the regional power grid corresponding to the minimum value in the power adjustment distances is the regional power grid to be accessed, and takes step S1173 as an example, if the power adjustment distance of the regional power grid 4 is the minimum, it determines that the regional power grid 4 is the regional power grid to be accessed. The regional power grid closest to the power grid is selected for power adjustment, so that loss in the power adjustment process is effectively reduced, and power can be supplied more timely.

One possible implementation manner of the embodiment of the present application, the method further includes step S119 (not shown in the figure), step S120 (not shown in the figure), and step S121 (not shown in the figure), and step S119 may be performed after step S106, where,

step S119, obtaining the historical starting times of each peak shaver set in the area.

For the embodiment of the application, the electronic device may obtain the historical starting times of the area from the database, or may obtain the historical starting times of the area from the cloud server, which is not limited herein. For example:

The electronic equipment acquires the historical starting times of each peak shaver set in the area from the database:

the historical starting times of the peak shaver set 1 are 1000 times;

the historical starting times of the peak shaver set 2 are 2000 times;

the historical starting times of the peak shaver set 3 are 1500 times.

The more the historical starting times of the peak shaver set are, the greater the possibility that the peak shaver set is worn is indicated, so that the service life of the peak shaver set is influenced, and normal power supply cannot be performed.

Step S120, judging whether the historical starting times are larger than the preset starting times.

For the embodiment of the present application, taking step S119 as an example, assuming that the preset starting time is 1800 times, the historical starting time 2000 times of the peak shaver set 3 is greater than the preset starting time 1800 times, which indicates that the peak shaver set 3 may wear.

Step S121, if the historical starting times are larger than the preset starting times, the overhaul information is output.

The maintenance information is used for indicating that the peak shaver set needs maintenance.

For the embodiment of the present application, taking step S120 as an example, the electronic device outputs the maintenance information about the peak shaver set 3, where the maintenance information may be text information that "the peak shaver set 3 needs to be maintained" is sent to the user terminal device, or may be voice information that "the peak shaver set 3 needs to be maintained" sent by the speaker device, or may be other forms of maintenance information, which is not limited herein. The maintenance information is output to prompt relevant staff to maintain the peak shaver set in time, so that the situation that the peak shaver set is damaged and cannot be powered in time when the peak shaver set is required to power is reduced, and the power grid is overloaded is caused.
