TECHNICAL FIELD

[0001] The present application relates to the technical field of power load regulation, in particular to a flexible power load regulation method, device, equipment and medium for a power supply area. BACKGROUND

[0002] With the vigorous promotion of the rural coal-to-electricity policy, more and more areas introduce electric heating equipment. However, the use of a large number of electric heating equipment also brings new challenges to the power supply system. Electric heating equipment usually has a large power, and when multiple devices are running at full load at the same time, it puts a very high requirement on the power load of the power supply area. Especially during the peak period of electricity consumption, the situation becomes more severe.

[0003] Currently, in order to cope with the problem of power load in the power supply area, some areas try to upgrade the transformer to improve its carrying capacity, so as to alleviate the problem of excessive load. Some places choose to stagger the use of electricity, and guide users to use electric heating equipment during off-peak hours, so as to reduce the load pressure during the peak period of electricity consumption.

[0004] However, upgrading the transformer is costly, especially for old areas, the economic burden is heavy, and not all areas have enough space and conditions to upgrade the transformer. Staggered use of electricity requires high user cooperation, and it is difficult to implement in practice, and it is difficult to fundamentally solve the problem of load concentration. Therefore, there is an urgent need for a technical solution for flexible power load regulation in a power supply area. SUMMARY

[0005] The technical problem to be solved by the present application is to provide a flexible power load regulation method, device, equipment and medium for a power supply area, which aims to solve at least one of the above technical problems.

[0006] The technical solution of the present application to solve the above technical problems is as follows: In a first aspect, the present application provides a flexible power load regulation method for a power supply area, which adopts the following technical solution: A flexible power load regulation method for a power supply area, comprising: real-time acquisition of transformer load data of a target power supply area and running power and device type of an electric heating equipment of each user in the target power supply area, the device type being an electric heating wire type boiler or an electric heating radiation plate, the electric heating wire type boiler representing a two-phase controllable electric heating equipment with three-phase access and equipped with an intelligent isolation switch, the electric heating wire type boiler controlling the remaining phases after locking the self-starting phase through the intelligent isolation switch, the electric heating radiation plate representing a three-phase controllable electric heating equipment with single-phase access and equipped with a voltage regulator, and the electric heating radiation plate controlling three-phase voltage through the voltage regulator; establish a regulation queue based on the device type of the electric heating device of each user, the regulation queue comprising a first regulation queue and a second regulation queue arranged in sequence, the first regulation queue comprising one regulatable phase of the electric heating device of each user, and the second regulation queue comprising the remaining regulatable phases of the electric heating device of each user, the remaining regulatable phases representing the phases of the electric heating device of each user other than the phases in the first regulation queue; based on the transformer load data, determining a target regulation strategy of the regulation queue, and based on the target regulation strategy and the operating power of the electric heating device of each user, regulating the phase of the load regulation device installed on each of the electric heating devices in the regulation queue until the transformer load data meets a set power threshold, the target regulation strategy being a load overload regulation strategy or a load normal regulation strategy.

[0007] The present application has the advantages that: the two types of electric heating devices, i.e., electric heating wire boilers and electric heating radiators, can be simultaneously supported for power supply area power load regulation; by using the regulation queue and cooperating with the corresponding regulation strategy, the influence on each household can be minimized, and in most cases, only one phase of the heating user is affected, thereby ensuring the user heating experience; multiple regulation queues are used, and the regulation strategy is equally treated for each user, thereby avoiding excessive regulation of individual users; and the method can dynamically adjust the power load of the power supply area according to the transformer load data, ensure that the area load remains within a reasonable range, avoid the phenomenon of excessive load or even overload of the area transformer, and reduce the damage to the transformer.

[0008] On the basis of the above technical solution, the present application can be further improved as follows.

[0009] Further, the establishing of the regulation queue based on the device type of the electric heating device of each user comprises: allocating one regulatable phase of the electric heating device of each user to the first regulation queue, and arranging the one regulatable phase of the electric heating device of each user in the first regulation queue according to a phase cycle arrangement rule, so that the phases of the three consecutive regulation phases of all the electric heating devices in the first regulation queue are not repeated; allocating the remaining regulatable phases of the electric heating device of each user to the second regulation queue, and arranging the remaining regulatable phases in the second regulation queue according to a user identification dispersion arrangement rule, so that the phases of the regulation phases of the same user in the second regulation queue are not continuous, the first regulation queue and the second regulation queue both comprising the current state of the corresponding phase of the electric heating device of each user, the current state being a regulatable state or a recoverable state, the regulatable state representing the state of the corresponding phase of the electric heating device satisfying the load regulation, and the recoverable state representing the state of the corresponding phase of the electric heating device satisfying the load recovery.

[0010] The beneficial effect of the further scheme is that: the control queue can be established according to the type of the electric heating equipment of the user, the first control queue is arranged according to the phase cycle rule so that the phases of the three consecutive control phases are not repeated, three-phase balanced control is realized, and the three-phase unbalance degree is ensured; the second control queue is dispersedly arranged according to the user identifier so that the phase of the control phase of the same user is not continuous, the influence on each household is minimized, and the user heating experience is ensured; and the control queue contains the current state of the corresponding phase of the electric heating equipment, which facilitates the determination of the equipment state and better subsequent load control and recovery operation.

[0011] Further, the target control strategy of the control queue is determined based on the transformer load data, including: if the ratio of the transformer load data to the transformer rated power is greater than a preset load threshold, the target control strategy of the control queue is determined as a load overload control strategy; if the ratio of the transformer load data to the transformer rated power is not greater than the preset load threshold, the target control strategy of the control queue is determined as a load normal control strategy.

[0012] The beneficial effect of the further scheme is that: according to the size relationship between the transformer load data and the preset load threshold, the load overload control strategy or the load normal control strategy can be accurately determined, and then corresponding measures are taken according to different load conditions, the power load of the power supply area is flexibly controlled, and the stability and safety of power supply are ensured.

[0013] Further, when the target control strategy of the control queue is the load overload control strategy, the phase of the load control device added to each electric heating equipment in the control queue is controlled based on the target control strategy and the rated power of the electric heating equipment of each user, including: based on the transformer load data and the rated power, the excess power of the target power supply area is calculated; based on the operating power and the rated power of each electric heating equipment of the user, the control power of each electric heating equipment of the user is determined; if there is a controllable state phase in the first control queue, the first control queue is traversed, and it is judged whether the sum of the control powers of the electric heating equipment of each user corresponding to the controllable state phase in the first control queue of the current traversal number meets the excess power demand; If the sum of the control powers of the electric heating devices of the users corresponding to the phases in the controllable state in the first control queue of the current iteration number meets the excess power demand, based on a preset first control rule, the phases of the electric heating devices of the users in the first control queue are controlled in turn from the control position of the first control queue, and the current state of the electric heating devices of the users in the first control queue that have been controlled is recorded as a recoverable state, until the sum of the control powers of the electric heating devices of the users in the first control queue meets the excess power demand, the control of the phases of the electric heating devices of the users in the first control queue is stopped, and a new control position of the first control queue is determined based on the queue position of the electric heating devices of the users that have been controlled. If the sum of the control powers of the electric heating devices of the users corresponding to the phases in the first control queue of the current iteration number does not meet the excess power demand, after the phases of the electric heating devices of all the users in the first control queue are controlled, the second control queue is iterated, based on a preset second control rule, the phases of the electric heating devices of the users in the second control queue are controlled in turn, and the current state of the electric heating devices of the users in the second control queue that have been controlled is recorded as a recoverable state, until the sum of the control powers of the electric heating devices of the users in the second control queue meets the excess power demand, the control of the phases of the electric heating devices of the users in the second control queue is stopped, and a new control position of the second control queue is determined based on the queue position of the electric heating devices of the users that have been controlled.

[0014] The beneficial effects of the above further scheme are that the excess power can be calculated according to the transformer load data and the operating power of the electric heating devices, and then based on the conditions of different control queues, the first control queue is preferentially controlled, and when the first control queue cannot meet the control requirement, the second control queue is controlled, so that the phases of the load control devices added to the electric heating devices are accurately controlled, the transformer load data meets the set power threshold, and the power control can be orderly performed when the load is overloaded, and the influence on most users is reduced, and in most cases, only one phase of the electric heating device of a user is affected.

[0015] Further, before the above-mentioned controlling the phases of the electric heating devices of the users in the first control queue in turn from the control position of the first control queue based on the preset first control rule, the method further comprises: judging whether the control time of the electric heating devices of the users corresponding to the last iteration number of the current iteration number is greater than a set time threshold; If the control time of the electric heating devices of the users corresponding to the last iteration number of the current iteration number is greater than the set time threshold, it is determined that the electric heating devices of the users in the first control queue can be controlled. If the regulation time of the electric heating device of the user corresponding to the last iteration number of the current iteration number of the regulated user is not greater than the set time threshold, it is determined that the electric heating device of the user in the first regulation queue cannot be regulated.

[0016] The beneficial effect of the further scheme is to avoid frequent regulation of the regulation device, thereby prolonging the service life of the regulation device.

[0017] Further, when the target regulation strategy of the regulation queue is the load normal regulation strategy, the phase of the load regulation device added to each electric heating device in the regulation queue is regulated based on the target regulation strategy and the rated power of each electric heating device. Based on the transformer load data and the rated power, the surplus power of the target power supply area is calculated. Based on the regulation power of each electric heating device of each user, the recovery power of each electric heating device of each user is determined. If there is a recoverable phase in the second regulation queue, the second regulation queue is iterated to determine whether the sum of the recovery powers of the electric heating devices of each user corresponding to the recoverable phase in the second regulation queue of the current iteration number meets the surplus power requirement and the number of recoverable phases in the second regulation queue meets the set recovery number threshold, or whether the number of recoverable phases in the second regulation queue of the current iteration number meets the set recovery number threshold. If the sum of the recovery powers of the electric heating devices of each user corresponding to the recoverable phase in the second regulation queue of the current iteration number meets the surplus power requirement and the number of recoverable phases in the second regulation queue does not meet the set recovery number threshold, the phases of the electric heating devices of the users in the second regulation queue are recovered in sequence from the recovery position of the second regulation queue based on the preset second recovery rule, and the current state of the electric heating devices of the recovered users in the second regulation queue is recorded as a regulatable state until the sum of the recovery powers of the electric heating devices of the recovered users meets the recovery power requirement, the recovery of the phases of the electric heating devices of the users in the second regulation queue is stopped, and the new recovery position of the second regulation queue is determined based on the queue position of the recovered electric heating devices. If the number of phases in the second control queue in the current iteration meets the set recovery number threshold, the phases of the electric heating devices of the users in the second control queue are sequentially recovered from the recovery position of the second control queue based on the preset second recovery rule, and the current state of the electric heating devices of the recovered users in the second control queue is recorded as a controllable state, until the number of the phases of the recovered electric heating devices of the users meets the set recovery number threshold, the recovery of the phases of the electric heating devices of the users in the second control queue is stopped, and the new recovery position of the second control queue is determined based on the queue position of the recovered electric heating devices of the users.

[0018] The beneficial effect of the above further scheme is that when the power supply area load is normal, the surplus power is calculated according to the transformer load data and the rated power, and then the recovery power of each electric heating device is determined, the second control queue is iterated, the electric heating device phases are sequentially recovered according to the set rule, the power balance demand is met, the power fluctuation is avoided, the new recovery position is determined for subsequent control, the user heating experience is guaranteed, and the power load distribution of the power supply area is optimized.

[0019] Further, if the sum of the recovery powers of the electric heating devices of the users corresponding to the recoverable phases in the second control queue in the current iteration does not meet the surplus power demand and the number of the recoverable phases in the second control queue does not meet the set recovery number threshold, the method further comprises: After the phases of the electric heating devices of all the users in the second control queue are recovered, the first control queue is iterated, the phases of the electric heating devices of the users in the first control queue are sequentially recovered based on the preset second recovery rule, and the current state of the recovered electric heating devices of the users in the first control queue is recorded as a controllable state, until the sum of the recovery powers of the recovered electric heating devices of the users meets the surplus power demand and the number of the recoverable phases does not meet the set recovery number threshold, or the number of the phases of the recovered electric heating devices of the users meets the set recovery number threshold, the recovery of the phases of the electric heating devices of the users in the first control queue is stopped, and the new recovery position of the first control queue is determined based on the queue position of the recovered electric heating devices of the users.

[0020] The beneficial effects of the above further scheme are: real-time acquisition of transformer load data of a power supply station area and operation power and device type of a user electric heating device, control of different types of devices by intelligent isolation switches and voltage regulators, establishment of a control queue arranged according to rules, and control of phases according to a target control strategy when the transformer load data exceeds a threshold value. When the second control queue does not meet the demand for surplus power and the number of phases does not reach a set threshold value, the first control queue is continuously traversed for recovery, which can more accurately balance the power load of the power supply station area to meet the set power threshold value, thereby ensuring stable power supply; the establishment and control of the queue according to rules can avoid three-phase imbalance; the recovery of the control queue in order can reduce the impact on the user heating experience; and the judgment of the time threshold value before control can avoid frequent control of the control device and prolong its service life.

[0021] In a second aspect, the present application provides a flexible power load control device for a power supply station area, which adopts the following technical scheme: A flexible power load control device for a power supply station area comprises: An acquisition module is configured to acquire transformer load data of a target power supply station area and operation power and device type of an electric heating device of each user in the target power supply station area in real time, the device type being an electric heating wire type boiler or an electric heating radiation plate, the electric heating wire type boiler representing a two-phase controllable electric heating device with three-phase access and equipped with an intelligent isolation switch, the electric heating wire type boiler controlling the remaining phases after locking the starting phase by the intelligent isolation switch, and the electric heating radiation plate representing a three-phase controllable electric heating device with single-phase access and equipped with a voltage regulator, the electric heating radiation plate controlling three-phase voltage by the voltage regulator; An establishment module is configured to establish a control queue based on the device type of the electric heating device of each user, the control queue comprising a first control queue and a second control queue arranged in sequence, the first control queue comprising one controllable phase of the electric heating device of each user, and the second control queue comprising the remaining controllable phases of the electric heating device of each user, the remaining controllable phases representing other phases of the electric heating device of each user except the phase in the first control queue; A control module is configured to determine a target control strategy of the control queue based on the transformer load data, and control the phase of a load control device added to each electric heating device in the control queue based on the target control strategy and the operation power of the electric heating device of each user, until the transformer load data meets a set power threshold value, the target control strategy being a load overload control strategy or a load normal control strategy.

DETAILED DESCRIPTION

[0026] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme of the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are some of the embodiments of the present application, but not all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0027] In addition, the term "and / or" herein is only to describe the association relationship of the associated objects, which means that there can be three relationships, for example, A and / or B can represent the following three cases: A exists alone, A and B exist together, and B exists alone. In addition, the character " / " herein, unless otherwise specified, generally represents an "or" relationship between the associated objects before and after it.

[0028] The embodiments of the present application provide a power supply area flexible power load regulation method, which can be executed by an electronic device. The electronic device can be a server or a mobile terminal device. The server can be an independent physical server, a server cluster or a distributed system composed of multiple physical servers, or a cloud server providing cloud computing services. The mobile terminal device can be a notebook computer, a desktop computer, etc., but is not limited thereto.

[0029] like Figure 1 As shown, a flexible power load control method for a power supply area mainly includes: S1, real-time acquisition of transformer load data of the target power supply area and the operating power and equipment type of the electric heating equipment of each user in the target power supply area, wherein the equipment type is an electric heating wire boiler or an electric heating radiant panel. The electric heating wire boiler represents a two-phase adjustable electric heating equipment with three-phase access and equipped with an intelligent isolating switch. The electric heating wire boiler controls the remaining phases after locking the self-starting phase through the intelligent isolating switch. The electric heating radiant panel represents a three-phase adjustable electric heating equipment with single-phase access and equipped with a voltage regulator. The electric heating radiant panel controls the three-phase voltage through the voltage regulator. In an embodiment of the present application, a heating user profile can be established to record the type and power of the electric heating equipment. The electronic device obtains the operating power and equipment type of each user's electric heating equipment from the heating user profile.

[0030] In the embodiments of the present application, the electric heating wire boiler is a two-phase controllable electric heating device with three-phase power supply and equipped with an intelligent isolating switch. The electric heating wire boiler is characterized by its three-phase power supply. The intelligent isolating switch is a switch device with automatic control functions. The intelligent isolating switch achieves load control by locking the self-starting phase out of control, while the other two phases are controllable. This is because the device is connected to three-phase power, and disconnecting one phase during control does not affect the normal operation of the device. The intelligent isolating switch can be an electromagnetic isolating switch.

[0031] Electric radiant panels are single-phase, three-phase, controllable electric heating devices equipped with a voltage regulator. The voltage regulator precisely adjusts the voltage across all three phases, reducing the load by up to 50% on each phase. This is because the device only receives one phase of power and cannot be controlled by disconnecting that phase, so voltage regulation is employed.

[0032] S2, establishing a control queue based on the device type of each user's electric heating device, the control queue comprising a first control queue and a second control queue arranged in sequence, the first control queue comprising one controllable phase of each user's electric heating device, the second control queue comprising the remaining controllable phases of each user's electric heating device, the remaining controllable phases representing other phases of each user's electric heating device excluding the phases in the first control queue; In the embodiment of the present application, S2 specifically includes the following sub-steps: Allocate one adjustable phase of each user's electric heating device to a first control queue, and arrange one adjustable phase of each user's electric heating device in the first control queue according to a phase cyclic arrangement rule so that the phases of three consecutive adjustable phases of all electric heating devices in the first control queue do not overlap; The remaining controllable phase of the electric heating device of each user is allocated to a second control queue, and the remaining controllable phase is arranged in the second control queue according to the user identification, so that the phases of the control phases of the same user in the second control queue are discontinuous. The first control queue and the second control queue each include the current state of the corresponding phase of the electric heating device of each user, and the current state is a controllable state or a recoverable state. The controllable state represents a state in which the corresponding phase of the electric heating device meets the load control, and the recoverable state represents a state in which the corresponding phase of the electric heating device meets the load recovery.

[0033] In the embodiments of the present application, one controllable phase of the electric heating device of each user is allocated to the first control queue when the control queue is established. According to the phase cycle arrangement rule, one controllable phase of the electric heating device of each user is arranged in the first control queue, so that the phases of the three controllable phases of all the electric heating devices in the first control queue are not repeated. For example, like the queue 1 in the example: {user 1, A phase} {user 2, B phase} {user 3, C phase} {user 4, A phase} {user 5, B phase} {user 6, C phase} {user 7, A phase}. This can effectively avoid current imbalance, because if the same phase of electricity is continuously controlled, it will cause a large difference in three-phase current, affecting the stability of power supply.

[0034] The remaining controllable phase of the electric heating device of each user is allocated to a second control queue. The remaining controllable phase is arranged in the second control queue according to the user identification, so that the phases of the control phases of the same user in the second control queue are discontinuous. And the first control queue and the second control queue each include the current state of the corresponding phase of the electric heating device of each user, and the current state is a controllable state or a recoverable state. The controllable state represents a state in which the corresponding phase of the electric heating device meets the load control, and the recoverable state represents a state in which the corresponding phase of the electric heating device meets the load recovery. For example, the second queue: {user 1, B phase} {user 2, C phase} {user 3, A phase} {user 4, B phase} {user 5, C phase} {user 6, A phase} {user 7, B phase} {user 2, A phase} {user 6, B phase} {user 7, C phase}. A reasonable queue arrangement ensures the fairness and effectiveness of the control, and avoids excessive control of individual users.

[0035] S3, based on the transformer load data, determining a target control strategy of the control queue, and based on the target control strategy and the operating power of the electric heating device of each user, controlling the phase of the load control device installed on each of the electric heating devices in the control queue until the transformer load data meets a set power threshold. The target control strategy is a load overload control strategy or a load normal control strategy.

[0036] In the embodiments of the present application, the target regulation strategy of the regulation queue is determined based on the transformer load data, including: If the ratio of the transformer load data to the transformer rated power is greater than a preset load threshold, the target regulation strategy of the regulation queue is determined as a load overload regulation strategy. If the ratio of the transformer load data to the transformer rated power is not greater than the preset load threshold, the target regulation strategy of the regulation queue is determined as a load normal regulation strategy.

[0037] In the embodiments of the present application, the load threshold can be configured, and the default is 80%. If the ratio of the transformer load data to the transformer rated power is greater than 80%, the target regulation strategy of the regulation queue is determined as a load overload regulation strategy. If the ratio of the transformer load data to the transformer rated power is not greater than 80%, the target regulation strategy of the regulation queue is determined as a load normal regulation strategy.

[0038] The load overload regulation strategy is a strategy for reducing the power of the electric heating device in the regulation queue, and the load normal regulation strategy represents a strategy for increasing the power of the electric heating device in the regulation queue.

[0039] In the embodiments of the present application, when the target regulation strategy of the regulation queue is a load overload regulation strategy, the phase of the load regulation device added to each electric heating device in the regulation queue is regulated based on the target regulation strategy and the rated power of each user's electric heating device, including: Based on the transformer load data and the rated power, the excess power of the target power supply area is calculated, excess power = collected power - rated power x load threshold; Based on the operating power and the rated power of each user's electric heating device, the regulation power of each user's electric heating device is determined. If there is a controllable phase in the first regulation queue, the first regulation queue is traversed to determine whether the sum of the regulation powers of the electric heating devices of each user corresponding to the controllable phase in the first regulation queue of the current traversal number meets the excess power requirement. If the sum of the control powers of the electric heating devices of the users corresponding to the phases in the controllable state in the first control queue of the current iteration number meets the excess power demand, based on a preset first control rule, the phases of the electric heating devices of the users in the first control queue are controlled in turn from the control position of the first control queue, and the current state of the electric heating devices of the users in the first control queue that have been controlled is recorded as a recoverable state, until the sum of the control powers of the electric heating devices of the users in the first control queue meets the excess power demand, the control of the phases of the electric heating devices of the users in the first control queue is stopped, and a new control position of the first control queue is determined based on the queue position of the electric heating devices of the users that have been controlled. If the sum of the control powers of the electric heating devices of the users corresponding to the phases in the controllable state in the first control queue of the current iteration number does not meet the excess power demand, after the phases of the electric heating devices of all the users in the first control queue are controlled, the second control queue is iterated, based on a preset second control rule, the phases of the electric heating devices of the users in the second control queue are controlled in turn, and the current state of the electric heating devices of the users in the second control queue that have been controlled is recorded as a recoverable state, until the sum of the control powers of the electric heating devices of the users in the second control queue meets the excess power demand, the control of the phases of the electric heating devices of the users in the second control queue is stopped, and a new control position of the second control queue is determined based on the queue position of the electric heating devices of the users that have been controlled.

[0040] In the embodiments of the present application, before the phases of the electric heating devices of the users in the first control queue are controlled in turn from the control position of the first control queue based on the preset first control rule, the method further comprises: determining whether the control time of the electric heating devices of the users corresponding to the last iteration number of the current iteration number meets a set time threshold; If the control time of the electric heating devices of the users corresponding to the last iteration number of the current iteration number meets the set time threshold, it is determined that the electric heating devices of the users in the first control queue can be controlled. If the control time of the electric heating devices of the users corresponding to the last iteration number of the current iteration number does not meet the set time threshold, it is determined that the electric heating devices of the users in the first control queue cannot be controlled. In the embodiments of the present application, the set time threshold can be configured, and by default, it is 15 minutes before the electric heating devices can be controlled again. This avoids frequent control of the electric heating devices and prolongs the service life of the electric heating devices.

[0041] In the embodiment of the present application, the first regulation rule is that when the type of the electric heating device of the user is an electric heating wire type boiler, the current regulation switch is closed, the regulation can be performed, and a closing command is sent. The second regulation rule is that when the type of the electric heating device of the user is an electric heating radiation plate, the collected power / rated power>80%, the regulation can be performed, and a power reduction command is sent.

[0042] In the embodiment of the present application, during initialization, the regulation positions of the first regulation queue and the second regulation queue are set as the first positions of the regulation queue. The first regulation queue is traversed: starting from the regulation position, the phases in a state of being regulatable are searched, the regulation action is performed, and the regulation time and the regulation power are recorded. Each time the regulation is performed, a new regulation position is recorded, and the next time the regulation is performed, the list is traversed from the new regulation position. For example, the first queue: the last time 2 were regulated, this time the regulation starts from the 3rd record, and the regulatable phases are searched. If the first regulation queue is traversed and the regulation requirement is still not met, the second regulation queue is continued to be traversed until the regulation requirement is met.

[0043] By preferentially regulating the first regulation queue, when the first regulation queue cannot be regulated, the second regulation queue is regulated. When the load is over the standard, the first queue is preferentially regulated, only one phase of the heating user is regulated, the regulation amount is small, the heating experience is not affected, and the user does not perceive the temperature change. When the load is over the standard: the first regulation queue is regulated, the second queue is regulated, two or three phases of the heating user are regulated, the regulation amount is large, the heating experience is affected, and the user perceives the slow temperature rise.

[0044] In the embodiment of the present application, when the target regulation strategy of the regulation queue is a load normal regulation strategy, the phase of the load regulation device added to each electric heating device in the regulation queue is regulated based on the target regulation strategy and the rated power of the electric heating device of each user, and the method comprises the following steps. Based on the transformer load data and the rated power, the surplus power of the target power supply area is calculated, and the surplus power=rated power x load threshold-value-collected power. Based on the regulation power of each electric heating device of the user, the recovery power of each electric heating device of the user is determined. If there is a phase in a recoverable state in the second regulation queue, the second regulation queue is traversed, it is judged whether the sum of the recovery powers of the electric heating devices of the users corresponding to the phases in a recoverable state in the second regulation queue at the current traversal time meets the surplus power requirement and the number of the phases in a recoverable state in the second regulation queue does not meet the set recovery number threshold value, or it is judged whether the number of the phases in a recoverable state in the second regulation queue at the current traversal time meets the set recovery number threshold value. If the sum of the recovery powers of the electric heating devices of the users corresponding to the phases in the second control queue in the current iteration number meets the surplus power requirement and the number of the phases in the second control queue in the recoverable state does not meet the set recovery number threshold, the phases of the electric heating devices of the users in the second control queue are recovered in sequence from the recovery position of the second control queue based on the preset second recovery rule, and the current state of the recovered electric heating devices of the users in the second control queue is recorded as the controllable state, until the sum of the recovery powers of the recovered electric heating devices of the users meets the recovery power requirement, the recovery of the phases of the electric heating devices of the users in the second control queue is stopped, and the new recovery position of the second control queue is determined based on the queue position of the recovered electric heating devices of the users. If the number of the phases in the second control queue in the current iteration number meets the set recovery number threshold, the phases of the electric heating devices of the users in the second control queue are recovered in sequence from the recovery position of the second control queue based on the preset second recovery rule, and the current state of the recovered electric heating devices of the users in the second control queue is recorded as the controllable state, until the number of the recovered phases of the electric heating devices of the users meets the set recovery number threshold, the recovery of the phases of the electric heating devices of the users in the second control queue is stopped, and the new recovery position of the second control queue is determined based on the queue position of the recovered electric heating devices of the users.

[0045] If the sum of the recovery powers of the electric heating devices of the users corresponding to the phases in the second control queue in the current iteration number does not meet the surplus power requirement and the number of the phases in the second control queue in the recoverable state does not meet the set recovery number threshold, the method further comprises: After the phases of the electric heating devices of all the users in the second control queue are recovered, the first control queue is iterated, the phases of the electric heating devices of the users in the first control queue are recovered in sequence based on the preset second recovery rule, and the current state of the recovered electric heating devices of the users in the first control queue is recorded as the controllable state, until the sum of the recovery powers of the recovered electric heating devices of the users meets the surplus power requirement and the number of the recovered phases does not meet the set recovery number threshold, or the number of the recovered phases of the electric heating devices of the users meets the set recovery number threshold, the recovery of the phases of the electric heating devices of the users in the first control queue is stopped, and the new recovery position of the first control queue is determined based on the queue position of the recovered electric heating devices of the users.

[0046] In the embodiments of the present application, the first recovery rule is that when the electric heating device type of the user is an electric heating wire type boiler, the current control switch is closed, and the closing command is sent. The second recovery rule is that when the electric heating device type of the user is an electric heating radiation plate, the collected power / rated power is less than 60% (configurable), the recovery can be performed, and the power-up command is sent.

[0047] During initialization, the recovery positions of the first control queue and the second control queue are set to the first position of the control queue, the second control queue is traversed, the recoverable phases are searched from the recovery position, the recovery action is performed, and the recovery time and the control power are recorded. Each time the recovery is performed, the new recovery position is recorded, and the next time the recovery is performed, the list is traversed from the new recovery position. For example, the second control queue recovers 2 last time, and this time the recovery is performed from the third record to search for the recoverable phase. If the second control queue is traversed and the recovery requirement is still not met, the first control queue is traversed until the recovery requirement is met.

[0048] The method can support two types of electric heating device, i.e., the electric heating wire type boiler and the electric heating radiation plate, to perform power supply area power load control; by using the control queue and cooperating with the corresponding control strategy, the influence on each household can be minimized, and in most cases, only one phase of the heating user is affected, thereby ensuring the user heating experience. The use of multiple control queues and the control strategy treat each user equally, thereby avoiding excessive control of individual users. Moreover, the method can dynamically adjust the power consumption load of the power supply area according to the transformer load data, ensure that the area load is kept within a reasonable range, avoid the phenomenon that the area transformer load is too large or even overloaded, and reduce the damage to the transformer.
