[0002] A household energy management system is a virtual power station management system for households. The household energy management system can automatically control the switching or power adjustment of household appliances according to preset rules or user instructions, or can provide personalized energy-saving suggestions to users, such as adjusting the air conditioner temperature according to the weather, or turning off the lights when no one is at home. However, the household energy management system in the related art usually only manages household appliances, and does not manage the power supply mode.

[0087] The technical solutions in the embodiments of the present application will be described clearly and completely in combination with the drawings in the present application. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0088] The technical solutions in the embodiments of the present application can be applied to an energy management system, and each energy management system is used for managing devices in a preset range. For example, one energy management system can be used for managing devices in a home, and another energy management system can be used for managing devices in a factory. Figure 1 is a power line design diagram of the energy management system, Figure 2 is a communication topology diagram of the energy management system. The energy management system includes a hub device (HUB), a power supply device, a power consumption device, and a client.

[0089] In one embodiment, the technical solutions in the embodiments of the present application can be specifically applied to a hub device of an energy management system. The hub device has edge computing capability, and the hub device includes a scheduling control unit, a data center unit, a task center, a task execution unit, a hub control unit, and a hub unit. The task center is used for determining information of each task queue, and the information of the task queue includes but is not limited to: power consumption of each power consumption task, latest start time, target end time, average power median, and / or highest power threshold. The data center unit is used for obtaining instant data information of each power consumption device and power supply device. The hub unit is used for optimally scheduling each power consumption task according to the obtained information of the task queue and the instant data information. The task execution unit is used for executing the power consumption task according to the scheduling of the hub unit. The hub control unit is used for notifying the hub unit to re-schedule when data and / or power consumption tasks change.

[0090] In one embodiment, the power supply device includes a green power generation device, an electric energy storage device, and / or a power grid power supply device. The green power generation device can be a photovoltaic power generation device, and the photovoltaic power generation device includes a panel and an inverter. The electric energy storage device can be used as a power supply device or a power consumption device. In one embodiment, when the electric quantity stored in the electric energy storage device is greater than an electric quantity threshold, the electric energy storage device is determined as a power supply device. The power grid power supply device is used for supplying power to the power consumption device by using the power of the national power grid. It can be understood that the electricity price is different in different time periods, so the cost of using the power grid power supply device in different time periods is different, and therefore the priority of the power grid power supply device in different time periods can be different.

[0091] In one embodiment, the power consuming device includes a general load, a pre-arranged power consuming device corresponding to a pre-arranged power consuming task, an electric energy storage device, a charging pile, an electric energy conversion storage device, and / or a power selling device. The general load refers to a device used by a user in daily life, such as a refrigerator and a lamp. The pre-arranged power consuming device corresponding to the pre-arranged power consuming task can be a device that a user arranges to achieve a charging target at a certain time, and the charging target can be starting charging or being fully charged. The electric energy storage device has different priorities when it is used as a power consuming device according to the size relationship between the stored electric quantity and the electric quantity threshold. The charging pile can store electric energy, but the stored electric energy can only be used to charge a vehicle adapted to the charging pile. The electric energy conversion storage device is a device that converts electric energy into other energy and stores it, for example, the electric energy conversion storage device can be a heat pump that can convert electric energy into heat energy for storage. The power selling device can obtain electric energy from a power supply device and then sell the electric energy.

[0092] The client can provide a user with a selection of a working mode, a pre-arranged power consuming task, and management of a power consuming device. The client sends relevant instructions to the hub device in response to a user operation, the hub device performs calculation to determine an energy scheduling strategy, and controls each power supply device and power consuming device to execute the corresponding energy scheduling strategy. The energy scheduling strategy includes a power consuming time of the power consuming device and a power supply device that supplies power to the power consuming device.

[0093] In one embodiment, as shown in Figure 3 , an energy management method is provided. Although a logical sequence is shown in the step schematic diagram, in some cases, the steps shown or described can be performed in an order different from that shown in the figure.

[0094] The following are described in detail respectively. It should be noted that the sequence of the following embodiments is not limited as the priority sequence of the embodiments.

[0095] According to Figure 3 , the energy management method includes at least steps S110 to S140, which are described in detail as follows:

[0096] In step S110, a current working mode is determined, and a first priority of each power supply device in the working mode is determined.

[0097] Because each energy management system manages devices in a preset range, each device in the management range of the energy management system works in the same working mode. For example, an energy management system manages devices in a family, the current working mode is mode A, and each device in the family works in mode A.

[0098] The working modes include, but are not limited to, a self-use mode, a peak-valley arbitrage mode, a standby power mode and / or a holiday mode. In the self-use mode, the power generated by the green power generation device is used by the user's family without being sold. In the peak-valley arbitrage mode, the power is sold through the power selling device, and the sold power can be the power generated by the green power generation device or the power obtained from the power grid power supply device at a low electricity price. In the standby power mode, the power generated by the green power generation device can be stored in the power storage device, the charging pile and / or the power selling device, and / or the power can be converted and stored in the power conversion storage device. In the holiday mode, the power generated by the green power generation device can be stored in the power storage device and / or the power selling device.

[0099] The user can select the current working mode on the client, and the client sends a corresponding mode selection instruction to the hub device. The hub device can determine the current working mode according to the mode selection instruction, so as to control each device to work according to the working mode selected by the client. The first priority of each power supply device in different working modes is pre-configured. Therefore, after determining the working mode, the first priority of each power supply device can be determined. The first priority of the power supply device is mainly determined according to the cost, and the lower the cost, the higher the first priority of the power supply device.

[0100] In an embodiment, the first priority of the power supply device is a target priority, which indicates that the power supply device does not supply power in this working mode. For example, the first priority of the power storage device with an electric quantity less than the electric quantity threshold is a target priority, and the power storage device with an electric quantity less than the electric quantity threshold is not a power supply device in this mode.

[0101] In step S120, the second priority of each power-consuming device when different power supply devices supply power is determined in the working mode.

[0102] The second priority of the power-consuming device is mainly determined according to the power consumption time of the power-consuming device, the emergency degree of power consumption, etc. The earlier the power consumption time of the power-consuming device, the more urgent the emergency degree of power consumption, and the higher the second priority.

[0103] In the same working mode, the second priority of each power-consuming device when different power supply devices supply power can also be different. The first priority of the power-consuming device is a target priority, which indicates that the power-consuming device does not consume power when the power supply device supplies power in this working mode. For example, the second priority of the charging pile is a target priority when the power storage device supplies power in the self-use mode, and the charging pile does not consume power.

[0104] In an embodiment, the first priority and the second priority can be configured according to Table 1.

[0105] Table 1. Configuration table of first priority and second priority

[0106]

[0107] The first column in Table 1 is each working mode, the second column is the power supply device for power supply in each working mode, the first priority of the power supply device arranged in the front column is higher, and the last several columns are the power consumption devices. In the checked power consumption devices, the power consumption device arranged in the left side has a higher second priority, and the un-checked power consumption device represents that the power consumption device does not consume power when the current working mode is powered by the current power supply device. The power grid power supply device-valley represents the power grid power supply device when the electricity price is low, and the power grid power supply device-peak represents the power grid power supply device when the electricity price is high.

[0108] The first electric energy storage device is an electric energy storage device with an electric quantity not greater than an electric quantity threshold, and the second electric energy storage device is an electric energy storage device with an electric quantity greater than the electric quantity threshold. For example, the third row in Table 1 represents that when the second electric energy storage device is powered in the self-generation and self-use mode, the power consumption devices include general loads, reservation power consumption device 1 and reservation power consumption device 2, and the order of each power consumption device according to the second priority from high to low is: general loads are higher than reservation power consumption device 1, and reservation power consumption device 1 is higher than reservation power consumption device 2.

[0109] In step S130, the first operating parameter of the power supply device and the second operating parameter of the power consumption device are obtained.

[0110] The operating parameter of the device is various indexes for describing the operation of the device, including electrical parameters and / or performance parameters, etc. The device can be a power supply device, and can be a power consumption device. The operating parameter of the device can change in real time, so the operating parameter of the device can be periodically and dynamically obtained. The first operating parameter of the power supply device includes the power supply quantity of the power supply device. The operating parameter of the power consumption device includes the power consumption quantity, the average power consumption power and / or the maximum power consumption power, etc.

[0111] In step S140, according to the first priority and the second priority, and the first operating parameter and the second operating parameter, the power supply device for power supply to each power consumption device is determined.

[0112] In order to save costs, when the power supply device is determined, the power supply device with a high first priority is used first. When it is determined which power consumption devices are powered, the power supply device corresponding to the power consumption device with a high second priority is determined first. According to the first operating parameter of the power supply device and the second operating parameter of the power consumption device, it can be determined whether each power supply device is sufficient to ensure the power consumption demand of each power consumption device.

[0113] Therefore, according to the first operation parameter and the second operation parameter, the power supply device for supplying power to each of the power consuming devices is determined in sequence according to the first priority of the power supply device and the second priority of the power consuming device from high to low.

[0114] By adopting the technical solution of the embodiment of the application, the first priority of each of the power supply devices is different in different working modes, and the second priority of the power consuming device is different when the power supply device in different working modes supplies power. Therefore, the power supply device for supplying power to each of the power consuming devices is determined according to the first operation parameter of the power supply device and the second operation parameter of the power consuming device, and the first priority and the second priority, which is reasonable considering different working modes, and the priority of the power supply device and the priority of the power consuming device in different working modes.

[0115] On the basis of the above technical solution, as an embodiment, the first operation parameter includes a power supply amount, and the second operation parameter includes a power consumption amount; and step S140 can specifically include:

[0116] According to the power supply amount of the power supply device and the power consumption amount of the power consuming device, whether the remaining power supply amount of each of the power supply devices is less than the power consumption amount of a target power consuming device is determined in sequence according to the first priority from high to low and the second priority from high to low; the target power consuming device is the power consuming device with the highest second priority among each of the power consuming devices whose corresponding power supply device has not been determined.

[0117] When the remaining power supply amount of the power supply device is less than the power consumption amount of the target power consuming device, whether the power supply amount of the power supply device with the next first priority is less than the power consumption amount of the target power consuming device is determined.

[0118] When the remaining power supply amount of the power supply device is not less than the power consumption amount of the target power consuming device, it is determined that the power supply device supplies power to the target power consuming device, and whether the newly remaining power supply amount of the power supply device is less than the power consumption amount of the newly target power consuming device is determined until the power supply device for supplying power to each of the power consuming devices is determined.

[0119] As Figure 4As shown, the current configuration is parsed to obtain the current working mode, and then the first priority of each power supply device and the second priority of each power consumption device are determined. The power supply amount of each power supply device and the power consumption amount of each power consumption device are obtained. The power supply amount of the green power generation device is the sum of the remaining power amount and the to-be-generated power amount of the green power generation device; the to-be-generated power amount is determined according to the power generation power and the time of the green power generation device. The power supply amount of the power storage device is the stored power amount of the power storage device. The power supply amount of the power grid power supply device can be regarded as infinite, but the power supply amount of the power grid power supply device in a certain time period can be determined according to the time period and the power of the power grid power supply device. The power consumption amount of the power consumption device can be a scheduled power consumption amount, or a power consumption amount determined according to experience, or a power consumption amount predicted by using a neural network model.

[0120] First, the power consumption device with the highest second priority is determined as a target power consumption device. According to the power supply amount of the power supply device with the highest first priority and the power consumption amount of the target power consumption device, it is determined whether the power supply amount of the power supply device is greater than or equal to the power consumption amount of the target power consumption device. In the case where the power supply amount of the power supply device is greater than or equal to the power consumption amount of the target power consumption device, the power supply device is determined as a power supply device for supplying power to the target power consumption device, and the difference between the power supply amount of the power supply device with the highest first priority and the power consumption amount of the target power consumption device is determined as the remaining power supply amount of the power supply device. In addition, the power consumption device with the highest second priority among the power consumption devices other than the target power consumption device is determined as the latest target power consumption device.

[0121] In the case where the power supply amount of the power supply device is not greater than or equal to the power consumption amount of the target power consumption device, it is determined whether the power supply device of the next priority can supply power to the target power consumption device: according to whether the power supply amount of the power supply device of the next priority is greater than or equal to the power consumption amount of the target power consumption device, it is determined whether the power supply device of the next priority can supply power to the target power consumption device, until the power supply device corresponding to the target power consumption device is determined.

[0122] When the power supply device corresponding to one power consumption device is determined, the power supply device corresponding to the power consumption device of the next priority is continuously determined: it is determined whether the remaining power supply amount of the power consumption device with the highest second priority is greater than or equal to the power consumption amount of the latest target power consumption device. In the case where the remaining power supply amount of the power consumption device with the highest second priority is greater than or equal to the power consumption amount of the latest target power consumption device, the power supply device is determined as a power supply device for supplying power to the latest target power consumption device.

[0123] According to the technical solution of the embodiment of the present application, each power consumption device can be sequentially determined with a corresponding power supply device according to the first priority from high to low and the second priority from high to low. According to the first priority from high to low, the cost can be guaranteed to be low, and according to the second priority from high to low, the power consumption device with an earlier power consumption time or a more urgent power consumption emergency can be determined with a power supply device in priority.

[0124] On the basis of the above technical solution, as an embodiment, as shown in Figure 5 The energy management method further includes steps S150 to S180.

[0125] In step S150, in response to a submitted reservation power consumption task, the second priority of a reservation power consumption device corresponding to the reservation power consumption task when powered by different power supply devices in the working mode is obtained.

[0126] The reservation power consumption task can be a power consumption task reserved by a user through a client, and the reservation power consumption task corresponds to a reservation power consumption device. The reservation power consumption device is also a power consumption device, and therefore the second priority of the reservation power consumption device can also be obtained.

[0127] In step S160, the second running parameter of the reservation power consumption device and the time parameter of the reservation power consumption task are obtained.

[0128] The time parameter of the reservation power consumption task can be a start time, a latest start time, and / or a target end time, etc. of the reservation power consumption task. The reservation power consumption task usually has a time parameter, which can be directly determined at the time of reservation or calculated. For example, the user can reserve to fully charge the car at 8 am tomorrow, in which 8 am tomorrow is a target end time directly determined at the time of reservation; based on 8 am tomorrow and the time length required for full charging, the latest start time is calculated.

[0129] The method for obtaining the second running parameter of the reservation power consumption device is the same as the method for obtaining the second running parameter of other power consumption devices.

[0130] In step S170, the power consumption period of the reservation power consumption task is determined according to the second running parameter of the reservation power consumption device and the time parameter of the reservation power consumption task.

[0131] In the case that the power consumption period of the reservation power consumption task can be adjusted, the power consumption period of the reservation power consumption task can be determined according to the second running parameter of the reservation power consumption device and the time parameter of the reservation power consumption task.

[0132] In one embodiment, the second operation parameter comprises power consumption and average power consumption, and the time parameter of the scheduled power consumption task comprises a target end time; and step S170 can comprise: determining a power consumption duration according to the power consumption and the average power consumption of the scheduled power consumption device; and determining a power consumption period of the scheduled power consumption task according to the target end time and the power consumption duration.

[0133] The quotient of the power consumption and the average power consumption of the scheduled power consumption device is determined as the power consumption duration. The difference between the target end time and the power consumption duration is determined as the start time of the scheduled power consumption task. The power consumption period of the scheduled power consumption task is determined according to the start time and the power consumption duration.

[0134] In this way, the power consumption period of the scheduled power consumption task can be determined, so that the scheduled power consumption task is executed in the power consumption period of the scheduled power consumption task, thereby achieving planning of the scheduled power consumption task in the time dimension.

[0135] In step S180, a power supply device for supplying power to the scheduled power consumption device in the power consumption period is determined according to the first priority and the second priority, and the first operation parameter and the second operation parameter.

[0136] In determining the power supply device corresponding to each scheduled power consumption device, the scheduled power consumption device is regarded as a power consumption device, and the power supply device for supplying power to each power consumption device is determined in turn according to the first priority of each power supply device in descending order and the second priority of each power consumption device in descending order. The power supply device supplies power to the scheduled power consumption device in the power consumption period of the scheduled power consumption device.

[0137] In an embodiment, based on the technical solution of the embodiment of the present application, user A sets a reservation through the client at 12:00 on August 28, 2024, with the content being: needing to travel at 8:00 on August 29, 2024, and requiring the smart electric vehicle under the garage to be charged to full power before that. The cumulative power that can be generated by the green power generation device of the user is set to 10 kWh from 12:00 to 8:00. When the user sets the reservation, the remaining power of the smart electric vehicle is 4 kWh, and the full power capacity of the smart electric vehicle is 60 kWh. Through calculation, it is known that 56 kWh of power needs to be charged for the smart electric vehicle of the user before 8:00. The energy management system inquires that the charging power of the charging pile for charging the smart electric vehicle is 7 kW, so it takes 8 hours to charge 56 kWh of power for the smart electric vehicle. The full power of the power storage device of the user is set to 10 kWh, and it is calculated that other loads (such as air conditioners, etc.) need to consume 3 kWh during this period. It is set that 06:00-22:00 is the peak price interval of the power grid, and 22:00-06:00 is the valley price interval of the power grid. Through calculation, 39 kWh needs to be purchased through the power supply device of the power grid before 8:00 the next day. The charging power is 7 kW, and it takes about 5.6 hours to charge 39 kWh of power.

[0138] The central device of the energy management system knows through scheduling and calculation that a task needs to be created through a task unit (the earliest start time is 22:00, the latest start time is 00:00, the target end time is before 8:00, the power is 7 kW, and the maximum power is 7 kW). The central device of the energy management system puts the above task into the queue and waits for further scheduling. The central device of the energy management system will dynamically adjust the attributes of the task according to the instantaneous load power consumption of the user, the remaining power of the battery, and the power generation power of the green power generation device before the latest start time. Until the latest start time of the task calculated this time is within the set threshold (n minutes) from the current time, the task will be scheduled into the execution unit for execution.

[0139] The above execution path is: starting to charge the smart electric vehicle at 00:00, with a power of 7 kW, and after the power supply device of the power grid charges for 5.6 hours, switching to the green power generation device for charging, using the power storage device for charging after the green power generation device is used up. Through the above calculation, the smart electric vehicle is fully charged before 8:00, and the minimum required 39 kWh of power is purchased during the valley price period.

[0140] By adopting the technical solution of the embodiment of the present application, on the one hand, the corresponding power supply device can be determined for the reservation power consumption device in the order of the first priority from high to low and the order of the second priority from high to low, so as to ensure that the cost is low. On the other hand, the power consumption period of the reservation power consumption task is determined, so as to realize the planning of the reservation power consumption task in the time dimension.

[0141] On the basis of the above technical solutions, as shown in Figure 6 the working modes include: self-generation self-use mode, peak-valley arbitrage mode, standby power mode and / or holiday mode. Different working modes correspond to different candidate electrical equipment; in the self-generation self-use mode, the candidate electrical equipment includes: electrical energy storage equipment, charging pile and / or electrical energy conversion storage equipment; in the peak-valley arbitrage mode, the candidate electrical equipment includes: electrical energy storage equipment, electricity buying equipment, charging pile and / or electrical energy conversion storage equipment; in the standby power mode, the candidate electrical equipment includes: electrical energy storage equipment; in the holiday mode, the candidate electrical equipment includes: electrical energy storage equipment; the energy management method further includes: determining whether the candidate electrical equipment is the electrical equipment according to the target setting of the candidate electrical equipment.

[0142] In order to facilitate reading, hereinafter the electrical energy conversion storage equipment is described as a heat pump.

[0143] As an embodiment, each working mode can further subdivide the working mode according to the working state of the charging pile and the heat pump. For example, the peak-valley arbitrage mode can be further subdivided into green electricity mode, economic mode and reservation mode; in the green electricity mode, only the green electricity power supply equipment is used to supply power to the charging pile and the heat pump; in the economic mode, the peak-valley time of electricity price can be set, so as to automatically supply power to the charging pile and the heat pump when the electricity price is low; in the reservation mode, the charging pile and the heat pump are supplied with power according to the reserved time. In an embodiment, the peak-valley arbitrage mode can further include charging pile reservation mode, heat pump reservation mode, charging pile economic mode and heat pump economic mode.

[0144] The user can select different working modes on the client, and through the configuration of battery use threshold, charging pile switch, electrical energy conversion storage equipment switch, electricity buying switch, peak-valley period, summer time switch, etc., the user can realize the customization of each working mode.

[0145] Through the configuration of battery use threshold, electricity buying switch, charging pile switch, electrical energy conversion storage equipment switch, etc., it can be determined whether the corresponding electrical energy storage equipment, electricity buying equipment, charging pile and / or electrical energy conversion storage equipment is determined as the electrical equipment. The candidate electrical equipment can be regarded as the electrical equipment with the target priority. Through the configuration of peak-valley period and summer time switch, the control of the power supply time of the charging pile and the heat pump in the economic mode can be realized.

[0146] In one embodiment, the determining whether the candidate power consumer is the power consumer according to the target setting of the candidate power consumer can include: obtaining the remaining power of the power storage device, and obtaining a set power threshold of the power storage device; and determining whether the power storage device is the power consumer when different power supply devices supply power in different working modes according to the size relationship between the remaining power of the power storage device and the power threshold.

[0147] The power storage device has different identities when the size relationship between the remaining power and the power threshold is different. When the remaining power of the power storage device is greater than the power threshold, the power storage device can be a power supply device or a candidate power consumer. When the remaining power of the power storage device is not greater than the power threshold, the power storage device can only be a candidate power consumer.

[0148] As can be seen from Table 1, when the remaining power of the power storage device is not greater than the power threshold, the power storage device is a power consumer in some working modes and is not checked in some working modes, i.e., the power storage device is a candidate power consumer.

[0149] Therefore, when the remaining power of the power storage device is not greater than the power threshold, the power storage device can be determined to be a power consumer according to the configured priority when different power supply devices supply power in different working modes.

[0150] In this way, whether the power storage device is a power supply device or a candidate power consumer can be determined according to the size relationship between the remaining power of the power storage device and the power threshold, so that the user can determine whether the power storage device is a power supply device or a candidate power consumer by customizing the power threshold. In addition, whether the power storage device as a candidate power consumer is a power consumer can also be determined according to the preconfigured priority.

[0151] On the basis of the above technical solutions, as shown in Figure 7 The energy management method further includes step S190.

[0152] In step S190, when it is detected that the first priority, the second priority, the first operating parameter and / or the second operating parameter change, the power supply device that supplies power to each power consumer is determined again.

[0153] In one embodiment, the change of the first priority and the second priority can be caused by the change of the working mode or the change of the setting by the user. The change of the second priority can also be caused by the user submitting a new reservation power consumption task.

[0154] In one embodiment, the first operation parameter and the second operation parameter are dynamically obtained by the energy management system according to a cycle, and the power consumption and the power supply amount in the operation parameters often change with time.

[0155] Because the power supply device corresponding to each power consumption device is determined according to the priority order, when the first priority and / or the second priority change, the power supply device supplying power to each power consumption device can change. When the first operation parameter and / or the second operation parameter change, the power supply device that can originally meet the power consumption demand of the power consumption device can no longer meet the demand, and thus the power supply device supplying power to each power consumption device needs to be determined again.

[0156] By adopting the technical solution of the embodiment of the present application, when the first priority, the second priority, the first operation parameter and / or the second operation parameter change, the power supply device supplying power to each power consumption device can be determined again according to the latest first priority, the second priority, the first operation parameter and / or the second operation parameter, so that the determined power supply device corresponding to each power consumption device is a reasonable scheme under the current state.
