Referring to fig. 1 and 2, a power distribution gateway 100 of the present application includes a processor 10, an energy management module 20 and an access management module 30. The processor 10 is electrically connected to both the energy management module 20 and the access management module 30, the energy management module 20 is electrically connected to the grid 200, the external power source 300 and the load 400, and the access management module 30 is electrically connected to the load 400. Wherein: the energy management module 20 is configured to obtain parameter information of the power grid 200, obtain first operation information of the power grid 200, and obtain second operation information of the external power source 300. The access management module 30 is configured to obtain data of the load 400 and environmental data of an environment in which the load 400 is located, and turn on or off the load 400 according to the load data and the environmental data. The processor 10 is further configured to determine grid-connected/off-grid information between the external power source 300 and the power grid 200 according to the parameter information, control the energy management module 20 to manage the operation modes of the external power source 300 and the power grid 200 according to the grid-connected/off-grid information, and control the energy management module 20 to manage the power supply of the power grid 200 and the charge and discharge of the external power source 300 according to the first operation information and the second operation information. The processor 10 is further configured to control the access management module 30 to turn on or off the load 400 according to the load data and the environment data.

The load 400 is a structure or a device capable of consuming electric energy, and the load 400 is electrically connected to the power grid 200 and the external power source 300 through the distribution gateway 100, respectively. The access management module 30 is capable of controlling the load 400 to be turned on or off. The external power source 300 includes a power generation power source 301 and an energy storage power source 303. The power generation power source 301 may be a wind power source or a solar power source capable of generating power from clean energy such as wind energy or solar energy, or may be a power generator capable of generating power from fuel such as gasoline or diesel. The energy storage power source 303 is capable of storing electric energy and supplying the stored electric energy to the load 400 for use, and the electric energy stored by the energy storage power source 303 can be derived from the power grid 200 or from the power generation power source 301. The parameter information is information such as line parameters of the power grid 200 and access conditions of the power grid 200. Line parameters of the power grid 200 include, but are not limited to, frequency or voltage, etc. Access conditions include, but are not limited to, electrical connection of grid 200 to distribution gateway 100, electrical connection of grid 200 to external power source 300, and the like.

For example: the energy management module 20 can obtain parameter information about whether the power grid 200 is electrically connected to the external power source 300. In the case where both the power generation power source 301 and the energy storage power source 303 are in a grid-connected state connected to the power grid 200, the electric power generated by the power generation power source 301 can be transmitted to the power grid 200, supplied to the energy storage power source 303 to store electric power, and/or directly supplied to the load 400. The grid 200 is capable of supplying power to the stored energy power source 303 and the load 400 to enable the stored energy power source 303 to store electrical energy and to enable the load 400 to function properly. The grid 200 is also able to provide a voltage to the energy storage power supply 303 to maintain the voltage across the load 400 constant, where both the power generation power supply 301 and the energy storage power supply 303 are able to provide current to the load 400. In the case where both the power generation power source 301 and the energy storage power source 303 are in an off-grid state in which they are not connected to the power grid 200, the power generation power source 301 can generate electric power and supply the energy storage power source 303 and the load 400. The energy storage power source 303 is also capable of providing power to the load 400, at which time the energy storage power source 303 is capable of providing a regulated voltage to the load 400.

The first operation information is operation information generated by the power grid 200 in the course of delivering electric power to the external power source 300 and the load 400, for example: the power consumption of the power grid 200, the power price fluctuation condition of the power grid 200, and/or the power outage condition of the power grid 200, etc. The second operation information is operation information generated by the external power supply 300 in the process of generating and transmitting electric power, for example: the power generation amount (electric power) of the power generation power source 301, the remaining amount of the energy storage power source 303, and/or the total power supply amount of the energy storage power source 303, and the like. Load data is data generated by load 400 during operation, such as: the amount of power used by each load 400, the period of operation of each load 400, and/or the duration of operation of each load 400, etc. The environmental data is data collected by the external sensor 500 and can be transmitted to the power distribution gateway 100, for example: weather, light intensity, temperature and/or humidity, etc.

In the power distribution gateway 100 of the present application, the power distribution gateway 100 can obtain various parameters of the power grid 200, the external power source 300 and the load 400, and control different power sources to supply power to the load 400 according to the first operation information of the power grid 200 and the second operation information of the external power source 300, so as to realize the function of saving the electric energy of the power grid 200. Depending on the load data and the environmental data of the loads 400, the power distribution gateway 100 is also able to control the operation of different loads 400 to make the operation of the loads 400 more intelligent and save power.

The power distribution gateway 100 is further described below with reference to the accompanying figures.

Referring to fig. 1 and 2, in some embodiments, the processor 10 is capable of acquiring the operation conditions of the external power supply 200, the external power supply 300 and the load 400 according to the acquired parameter information, the first operation information, the second operation information and the load data, and the processor 10 is also capable of acquiring the operation environment conditions of the external power supply 300 and the load 400 according to the acquired environment data. After obtaining the operation condition and the environment condition, the processor 10 can also control each module in the power distribution gateway 100 according to different operation conditions and different environment conditions, so as to realize the management of the power supply and the management of the load 400. The energy management module 20 can send the acquired parameter information, the first operation information and/or the second operation information to the processor 10, receive control commands from the processor 10 and an external user, and control the power supply process of the power grid 200 and the external power supply 300 according to the control commands. The access management module 30 is able to access the external load 400 and the sensor 500 and send the acquired load data and/or environmental data to the processor 10. The access management module 30 is also capable of receiving control commands from the processor 10 and external users and controlling the opening and closing of the load 400 according to the control commands.

Specifically, in certain embodiments, processor 10 is capable of controlling energy management module 20 to manage the modes of operation of grid 200 and external power source 300. In order for the load 400 connected to the power distribution gateway 100 to be always in an energized state, the external power source 300 should be always electrically connected to the power distribution gateway 100, at which time the energy management module 20 can acquire parameter data of the external power source 300. In the case where the power grid 200 is connected to the power distribution gateway 100, the energy management module 20 can read the relevant parameter information of the power grid 200, for example: current and voltage data in the grid 200 and transmits the data to the processor 10. The processor 10 can determine that the power grid 200 is connected to the power distribution gateway 100 at this time after receiving the related parameter information of the power grid 200, and the power grid 200 and the external power supply 300 are in a grid-connected state. In the case where the power grid 200 and the external power source 300 are in the grid-connected state, the processor 10 can intelligently control the power supply modes of the power grid 200 and the external power source 300 to the load 400 and the power supply modes between the power grid 200 and the external power source 300 according to the control instruction issued by the user or the first operation information, the second operation information, the load data and/or the environment data acquired in the power distribution gateway 100. In the case that the power grid 200 is not connected to the power distribution gateway 100, the energy management module 20 cannot read the related parameter information of the power grid 200, so that the processor 10 can determine that the external power source 300 is in the off-grid state at this time, and in the case that the external power source 300 is in the off-grid state, the processor 10 can intelligently control the power supply mode of the external power source 300 to the load 400 and the power supply mode between the power generation power source 301 and the energy storage power source 303 according to a control instruction issued by a user or second operation information, load data and/or environmental data acquired in the power distribution gateway 100.

More specifically, in some embodiments, processor 10 is also capable of controlling energy management module 20 to manage the manner in which grid 200 supplies power to load 400. In the case where the power grid 200 is connected to the power distribution gateway 100, the energy management module 20 can acquire first operation information generated during operation of the power grid 200. Based on the change in the first operating information, the processor 10 can formulate different control strategies to control the energy management module 20 to manage the power supply process of the power grid 200 to the load 400 in different ways.

For example: in the case where the power grid 200, the power generation source 301 and the energy storage source 303 are all capable of supplying power to the load 400, the processor 10 controls the energy management module 20 to preferentially use the power generation source 301 to supply power to the load 400 in order to use clean energy as much as possible while avoiding using the power of the power grid 200 to achieve the purpose of saving electricity. In the case that the power generated by the power generation source 301 can not only meet the requirement of the load 400, but also remain, the surplus power generated by the power generation source 301 can be supplied to the energy storage source 303 for storage. In the case where the amount of electricity stored in the energy storage power source 303 is at a maximum, the excess electrical energy generated by the power generation power source 301 can also be provided to the power grid 200 to generate additional revenue or to offset the consumption of electrical energy by the user in the power grid 200.

In the case that the external environment changes to cause the power generation source 301 to fail to generate the power, the processor 10 may control the energy management module 20 to preferentially use the power in the energy storage source 303 to supply the power to the load 400 so as to save the electricity fee. The processor 10 may also control the energy management module 20 to preferentially use the electric energy in the power grid 200 to supply power to the load 400, so as to keep the electric quantity stored in the energy storage power supply 303 as large as possible, and avoid that the load 400 cannot be supplied with power in an emergency state.

In the case where only the power generation source 301 and the energy storage source 303 supply power to the load 400, the processor 10 may control the energy management module 20 to preferentially supply power to the load 400 using the power generated by the power generation source 301. In the case where both the grid 200 and the power generation source 301 are capable of supplying power to the load 400, the processor 10 may control the energy management module 20 to preferentially use the power generation source 301 to supply power to the load 400 in order to use clean energy as much as possible.

Still more particularly, in some embodiments, the processor 10 is also capable of controlling the manner in which the external power source 300 is charged and discharged. The charging and discharging modes of the external power source 300 include, but are not limited to, discharging the power generation power source 301 to the load 400, discharging the power generation power source 301 to the energy storage power source 303, discharging the energy storage power source 303 to the load 400, and the like. In the case where the external power source 300 is connected to the power distribution gateway 100, the energy management module 20 can acquire second operation information generated during the operation of the external power source 300. Based on the change in the second operation information, the processor 10 can formulate different control strategies to control the energy management module 20 to manage the power supply process of the external power supply 300 to the load 400 in different manners.

For example: the processor 10 may control the energy management module 20 to directly supply the power generated by the power generation source 301 to the load 400, and the power generation source 301 is in a discharging state. In the case that the power generated by the power generation source 301 can not only meet the requirement of the load 400, but also be remained, the surplus power generated by the power generation source 301 can be supplied to the energy storage source 303 for storage, and the energy storage source 303 is in a charged state. In the event that the power generated by the power generation source 301 is insufficient for the load 400, the processor 10 may control the energy management module 20 to use the energy storage source 303 to supply power to the load 400, where the energy storage source 303 is in a discharge state.

Also specifically, in some embodiments, processor 10 is also capable of controlling access management module 30 to manage the turning on and off of load 400. When the access management module 30 is connected to the load 400 and the sensor 500, the access management module 30 can feed back the acquired load data and environment data to the processor 10. The processor 10 is able to formulate different control strategies based on the current load data and the environmental data to control the access management module 30 to manage the opening and closing of the load 400 in different ways. For example: in the case where the indoor temperature is high, the processor 10 can acquire temperature data among the environmental data and operation data of the load 400 (air conditioner, fan, or the like) that can lower the room temperature. With the load 400 in the off state, the processor 10 can control the access management module 30 to turn on the load 400 to reduce the indoor temperature. In the event that the load 400 is already in an on state, the processor 10 is able to control the access management module 30 to adjust the operating power of the load 400 to reduce the indoor temperature.

Referring to fig. 2 and 3, in some embodiments, the power distribution gateway 100 further includes an input/output module 40, where the input/output module 40 is a portion capable of sending information and receiving control instructions. The input/output module 40 is electrically connected to the processor 10, and when the input/output module 40 receives an external input signal, the input/output module 40 can read the input signal as a control command. In some embodiments, the processor 10 is capable of responding to the control command sent to the processor 10 by the input/output module 40, controlling the energy management module 20 to manage the power supply of the power grid 200 and the charging/discharging of the external power source 300 according to the first operation information and the second operation information, and controlling the access management module 30 to turn on or off the load 400 according to the load data and the environmental data. In other embodiments, access management module 30 can be capable of switching load 400 on or off in direct response to control instructions and based on load data and environmental data.

Specifically, in some embodiments, the input/output module 40 may be a communication module 41, where the communication module 41 may be connected to a terminal and/or a cloud end, and receive an input signal from the terminal and/or the cloud end to generate a control instruction. In one example, the communication module 41 can also be electrically connected to the processor 10, so that the control instruction can be transferred to the processor 10, and the processor 10 can control the energy management module 20, the access management module 30, and the communication module 41 to perform different functions according to the content of the control instruction, respectively. For example: in the case where the user issues an instruction to query the operation condition of the power distribution gateway 100, the processor 10 can control the communication module 41 to transmit at least one of the parameter information, the first operation information, the second operation information, the grid-connected/off-grid information, the load data, and the environment data from the processor 10 to the terminal and/or the cloud. In another example, the communication module 41 can be further electrically connected to the access management module 30, where the communication module 41 can directly transmit the control command to the access management module 30 and cause the access management module 30 to control the load 400 according to the control command.

More specifically, in other embodiments, the input/output module 40 may also be a display module 43, and the user can input control instructions through the display module 43. In one example, the display module 43 can be connected to the processor 10 to transmit the control instruction input by the user to the processor 10, and the processor 10 can control the energy management module 20, the access management module 30 and the display module 43 to perform different functions according to the content of the control instruction. For example: in the event that a user issues an instruction to query the operating condition of the power distribution gateway 100, the processor 10 can control the display module 43 to display at least one of parameter information, first operating information, second operating information, grid-tie/off-grid information, load data, and environmental data from the processor 10. In another example, the display module 43 can be further electrically connected to the access management module 30, where the display module 43 can directly transmit the control command to the access management module 30 and cause the access management module 30 to control the load 400 according to the control command.

Referring to fig. 3 and 4, in some embodiments, the power distribution gateway 100 may further include a power module 50, where the power module 50 is electrically connected to at least one of the processor 10, the energy management module 20, the access management module 30, and the input/output module 40, and the power module 50 is capable of supplying power to at least one of the processor 10, the energy management module 20, the access management module 30, and the input/output module 40 to maintain the normal operation of the respective modules within the power distribution gateway 100 without consuming the power in the power grid 200 and the external power source 300. In some embodiments, the power grid 200 and the external power source 300 are also capable of providing power to the power module 50.

The manner in which the power distribution gateway 100 is utilized will be described in connection with some specific embodiments.

In a specific embodiment, the power distribution gateway 100 can intelligently adjust the manner in which the grid 200 and the external power source 300 supply power to the load 400 to minimize the power supplied from the grid 200, and to use the power generation power source 301 and the energy storage power source 303 to supply power to the load 400 more. The power generation power supply 301 is a solar power supply, and the solar power supply is limited by weather during use, so that environmental data needs to be included in a reference range during adjustment of a power supply mode.

Specifically, the environmental data includes weather conditions for the first N days, and the load data includes the power consumption LP of each load 400 for the first N days. Based on the load data counted over the first N days, the processor 10 may obtain the average LP1 to LPN of the electricity consumption of each load 400, the average LAP of the electricity consumption levels of the total loads 400, and the average daily power generation amount of the power generation source 301 under different weather conditions. Namely: the average value of the power consumption of each load 400 is equal to the ratio of the sum of the daily power consumption of each load 400 to N in the previous N days.

Namely: lpn= (lpn1+lpn2+ … … +lpnn)/N.

The average LAP of the power usage level of the load 400 is equal to the ratio of the sum of the power usage amounts of all the loads 400 per day to N in the previous N days.

Namely: lap= (LAP 1+ LAP2+ … … + LAP)/N.

The second operation information includes the power generation amount E1 of the power generation source 301 in a sunny day in the previous N days, the power generation amount E2 of the power generation source 301 in a rainy day in the previous N days, and the current remaining power BP of the energy storage source 303. Based on the second operation information and the environmental data counted in the previous N days, the processor 10 is further capable of obtaining an average value PPV1 of the power generation amount of the power generation source 301 in the sunny day from the power generation amount E1 of the power generation source 301 in the sunny day in the previous N days, and obtaining an average value PPV2 of the power generation amount of the power generation source 301 in the rainy day from the power generation amount E2 of the power generation source 301 in the rainy day in the previous N days.

More specifically, in some embodiments, the processor 10 is further capable of estimating the estimated power supply amount of the power generation power supply 301 on the day based on the environmental data of the day (the weather condition of the day). In the case that the current weather condition is a sunny day, the estimated power supply amount E0 of the day is the sum of the average value PPV1 of the power generation amount of the power generation power supply 301 on the sunny day and the current remaining power BP of the energy storage power supply 303.

Namely: e0 =ppv1+bp.

In the case where the current weather condition is a rainy day, the estimated current power supply amount E0 is the sum of the average value PPV2 of the power generation amount of the power generation power supply 301 in the rainy day and the current remaining power BP of the energy storage power supply 303.

Namely: e0 =ppv2+bp.

The processor 10 is also capable of comparing the average LAP of the total load 400 with the estimated current day power E0 to derive the current day power consumption strategy. For example: in the case that the estimated current power E0 is smaller than the average LAP of the total load 400, the processor 10 may also send a prompt message and/or a recommendation message to the input/output module 40.

Further, in some embodiments, the hint information may include at least one of the following: the method comprises the steps of prompting a user to estimate insufficient power supply today, prompting the user to connect too much load 400 in the current day, prompting the user to current power price of the power grid 200, prompting the power generation of the power generation power supply 301 to be low or prompting the maximum power storage capacity of the energy storage power supply 303 to be insufficient.

Still further, in some embodiments, the advice information includes at least one of the following information: it is recommended to shut down at least one load 400 and provide an option to shut down the load 400, to control the external power source 300 or the grid 200 to supply the load 400 according to fluctuations in the price of electricity of the grid 200, to prioritize the external power source 300 to supply the load 400, to switch to the grid 200 to supply the load 400 in case of a depleted amount of electricity of the external power source 300 or to recommend an increase in the generated power of the generated power source 301 and/or a maximum stored amount of electricity of the stored power source 303.

In the case of selecting to shut down any load 400, the access management module 30 can automatically control to shut down any load 400, for example: the load 400 that is currently most energy consuming. The access management module 30 is also capable of shutting down the designated load 400 in accordance with control instructions issued by the user. In the case of selecting to control the external power source 300 or the power grid 200 to supply power to the load 400 according to fluctuation of the power price of the power grid 200, the energy management module 20 can acquire power price fluctuation information of the power grid 200. When the electricity price of the grid 200 is at a high value, the energy management module 20 controls the external power source 300 to supply power to the load 400. When the electricity price of the power grid 200 is at a low value, the energy management module 20 controls the power grid 200 to supply power to the load 400. In the event that the external power source 300 is selected to be preferred for powering the load 400, the energy management module 20 is able to control the external power source 300 to power the load 400, and in the event that the external power source 300 is depleted, the energy management module 20 again controls the grid 200 to power the load 400 to minimize the use of electrical energy within the grid 200.

In a specific embodiment, the power distribution gateway 100 can predict the outage probability under different days according to the first operation information of the power grid 200, and give a prompt to the user, before the outage, the energy management module 20 controls the power grid 200 and/or the power generation source 301 to supply power to the load 400, so as to save the residual power in the energy storage source 303 as much as possible, and enable the residual power in the energy storage source 303 to be supplied to the load 400 after the outage. Meanwhile, the power generation power supply 301 may also supply electric energy to the energy storage power supply 303 to increase the amount of electric energy stored in the energy storage power supply 303.

Specifically, the environmental data includes weather conditions of the first N days, and the first operation information includes days N and days X of outage of the power grid 200 in various weather conditions of the first N days, for example: days N1 of sunny days in the first N days and days X1 of blackout of sunny days N1 of grid 200 in the first N days, days N2 of rainy days in the first N days and days X2 of blackout of rainy days of grid 200 in the first N days or days N3 of windy days in the first N days and days X3 of blackout of windy days of grid 200 in the first N days. The processor 10 can obtain the outage probability η1 of the power grid 200 on a sunny day according to the outage days X1 on the sunny day in the previous N days and the sunny days N1 on the sunny day in the previous N days. Namely: η1=x1/n1×100%. The processor 10 is also capable of obtaining the blackout probability η2 of the power grid 200 in the rainy day from the blackout days X2 of the power grid 200 in the rainy day of the previous N days and the days N2 of the rainy day of the previous N days. Namely: η2=x2/n2×100%. The processor 10 is also capable of obtaining the outage probability η3 of the power grid 200 in the windy weather based on the outage days X3 of the power grid 200 in the windy weather in the previous N days and the days N3 of the windy weather in the previous N days. Namely: η3=x3/n3×100%. In the case where the processor 10 acquires the environmental data of the current day, the processor 10 can estimate the current day's outage probability according to the current weather conditions. The processor 10 can also obtain estimated outage periods of the power grid 200 under various weather conditions according to the outage moments t corresponding to the various weather conditions in the previous N days. For example: if the outage time t of the power grid 200 on a sunny day in the previous N days is 8:00, 10:00 and 15:00, the outage time t at the morning is more, and the estimated outage period of the power grid 200 on a sunny day is the morning.

The following table is specifically provided, wherein the total number of days n=10:

more specifically, in some embodiments, in the case where the current weather condition is a sunny day, the estimated outage probability η0 for the day is the outage probability η1 for the grid 200 on the sunny day. Under the condition that the current weather condition is a rainy day, the estimated power outage probability eta 0 of the current weather condition is the power outage probability eta 2 of the power grid 200 in the rainy day. Under the condition that the current weather condition is the windy weather, the estimated power outage probability eta 0 on the same day is the power outage probability eta 2 of the power grid 200 in the windy weather. In the case where the estimated current day outage probability η0 is greater than an early warning probability value preset in the processor 10 (the value may be set by a user or may be preset in the processor 10), the processor 10 may also be capable of sending prompt information and/or advice information to the input/output module 40.

Further, in some embodiments, the hint information may include at least one of the following: the user is prompted to estimate the power outage probability today, the remaining power of the current energy storage power supply 303 or the power generation amount of the current power generation power supply 301.

Still further, in some embodiments, the advice information includes: it is recommended that only the grid 200 be used to power the load 400 prior to the estimated outage period. In the case where only the power grid 200 is used to power the load 400 prior to the estimated outage period, the energy management module 20 can receive the control command and control the power grid 200 to preferentially power the load 400. The energy management module 20 can also control the external power source 300 to be disconnected from the load 400 to save the electric energy stored in the energy storage power source 303 as much as possible for use in the event of a power failure. If the user does not choose to employ the recommendation, the load 400 continues to use the power within the power generation source 301 and/or the stored energy source 303.

In one particular embodiment, the power distribution gateway 100 is capable of intelligently adjusting the charge and discharge process between the power generation power source 301 and the energy storage power source 303 based on current environmental data. Specifically, in some embodiments, access management module 30 is capable of obtaining current environmental data. The second operation information includes preset environmental data that the power generation power supply 301 needs to satisfy for power generation. In the case where the current environmental data is within the range of the preset environmental data that the power generation power supply 301 needs to satisfy for power generation, the energy management module 20 can control the power generation power supply 301 to supply power to at least the load 400. In the case where the current environmental data is out of the range of the preset environmental data that the power generation power supply 301 needs to satisfy for power generation, the energy management module 20 can control the energy storage power supply 303 to supply power to the load 400.

For example: in some embodiments, the power generation source 301 is a photovoltaic power generation source 301. The access management module 30 can obtain the current external light intensity and the preset light intensity required for the power generation of the power generation source 301. In the case that the current external light intensity is higher than the preset light intensity, the energy management module 20 is used to control the power generation source 301 to supply power to the load 400. In the case that the current external light intensity is lower than the preset light intensity, the energy management module 20 is configured to control the energy storage power source 303 to supply power to the load 400.

In one particular embodiment, the power distribution gateway 100 is capable of intelligently adjusting the usage of the load 400 based on current environmental data. Specifically, in some embodiments, access management module 30 is capable of obtaining current environmental data, the load data including a time of use of any one of loads 400 in the first N days, the time of use including, but not limited to, a duration of use and a time period of use of the load 400. Based on the time of use of the load 400 in the first N days, the processor 10 can obtain the average time of use of the load 400 per day and obtain the estimated time of use of the load 400 per day based on the current environmental data and the average time of use of the load 400. Based on the estimated time, the access management module 30 can control the load 400 to be turned on in advance before the estimated use time period, or automatically turn off the load 400 if the use time period reaches the estimated use time period.

Specifically, in certain embodiments, the environmental data includes indoor temperature and outdoor temperature. The access management module 30 is capable of acquiring a current indoor temperature T1 and a current outdoor temperature T2, and the processor 10 is configured to acquire a current indoor and outdoor temperature difference Δt according to the current indoor temperature T1 and the current outdoor temperature T2. The average usage time of the load 400 includes an average on time of the load 400 per day (derived from the usage time period), and the processor 10 can obtain a preset time of the load 400 that needs to be started in advance on the same day according to the current indoor and outdoor temperature difference and the average on time of the load 400 per day. For example: in the case that the current indoor and outdoor temperature difference is greater than the preset temperature difference, the access management module 30 is configured to start the load 400 in advance for a first preset time; in the case that the current indoor and outdoor temperature difference is smaller than the preset temperature difference, the access management module 30 is configured to start the load 400 in advance for a second preset time; wherein the first preset time should be greater than the second preset time.

In a specific embodiment, the power distribution gateway 100 can also determine the operation condition of the load 400 by comparing the expected power consumption of the load 400 with the current power consumption of the load 400, so as to avoid an operation failure or fire caused by excessive load 400. Specifically, the load data includes the power consumption of each load 400 in the first N days, and the processor 10 can obtain the estimated power consumption of each load 400 according to the power consumption of each load 400 in the first N days. The access management module 30 can obtain the power consumption of each load 400 on the same day. Based on the projected power usage of each load 400 and the power usage of each load 400 on the day, the processor 10 is able to obtain the operation of each load 400 on the day. The processor 10 is further configured to send a prompt message and/or a advice message to the input/output module 40 in case the power consumption of each load 400 on the current day is higher than the expected power consumption of each load 400. For example: the user is prompted to attach too many loads 400 and advise the user to turn off part of the loads 400.
