[0052] The present application will be described in detail below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in the embodiments of the present application can be combined with each other.

[0053] This embodiment provides a residential area energy dispatching method based on energy segmentation management, such as... Figure 1 As shown, the method includes:

[0054] Step 101: Obtain the electricity consumption period type, photovoltaic power output information, and electricity consumption information of each building in the target period of the residential area being dispatched.

[0055] The photovoltaic output information is used to indicate whether the target time period is a photovoltaic output period or a non-photovoltaic output period, and also to indicate the photovoltaic output of the target time period that belongs to a photovoltaic output period; the electricity consumption information includes the total electricity load of the target time period. Energy optimization scheduling is performed with 30-minute time periods.

[0057] By applying the technical solution of this embodiment, relevant information about the residential area during a specific target time period is collected, including: Electricity consumption period type: This typically refers to whether the period is a peak, off-peak, or low-peak electricity consumption period. Different period types may affect electricity prices and the tightness of power supply. Photovoltaic output information: This refers to the amount of electricity generated by photovoltaic systems (such as solar panels) within the residential area during the target time period. Photovoltaic output is affected by weather conditions (such as solar radiation intensity), time (such as day or night), and electricity consumption information of each building: This includes the expected or actual electricity consumption of each building during the target time period, as well as their respective electricity needs and characteristics. After collecting the necessary information, the next step is to formulate an energy dispatch strategy. This step is performed for each building within the residential area, and the specific operations include: Information analysis: The system performs a comprehensive analysis based on the collected electricity consumption period type, photovoltaic output information, and electricity consumption information of each building. This involves assessing the power supply and demand situation and considering how to utilize photovoltaic power, energy storage devices, and grid power purchases to meet the electricity needs of each building. Determining Energy Dispatch Strategies: Based on the above analysis, the system formulates specific energy dispatch strategies for each building. These strategies include: Energy Storage Device Charging and Discharging Strategies: Determining when to charge energy storage devices (e.g., when photovoltaic output exceeds electricity demand) and when to discharge them (e.g., during peak electricity demand periods or when photovoltaic output is insufficient). Grid Purchase Strategies: Determining how much electricity to purchase from the grid and when to purchase it based on electricity supply and demand and price information. This typically involves a trade-off between purchase costs and electricity demand. Executing Electricity Dispatch: Based on the determined energy dispatch strategies, the system dispatches electricity consumption for each building. This may include controlling the charging and discharging operations of energy storage devices and arranging electricity purchase transactions with the grid. Through such energy dispatch strategies, the system can utilize photovoltaic power more effectively, reduce grid purchase costs, and ensure that the electricity demand of each building is met. This contributes to achieving the goals of efficient energy utilization and energy conservation and emission reduction.

[0058] In this embodiment of the application, specifically for periods with photovoltaic power output, step 102 includes:

[0059] Step 102-1: If the target time period is a photovoltaic output period and the photovoltaic output is greater than or equal to the total electricity load, then photovoltaic power is used to supply power to the building's electricity load. The first charging power of the energy storage device is determined based on the maximum charging power of the energy storage device, the photovoltaic output, and the total electricity load. The remaining photovoltaic power is used to charge the building's energy storage device at the first charging power. When the energy storage device completes charging, the remaining photovoltaic power is input into the power grid.

[0060] Step 102-2: If the target time period is the photovoltaic output period and the photovoltaic output is less than the total electricity load, then determine the first discharge power of the energy storage device based on the maximum discharge power of the energy storage device, the photovoltaic output, the total electricity load, the discharge efficiency of the energy storage device, and the converter conversion efficiency of the energy storage device; determine whether the first discharge power and the photovoltaic output meet the demand of the total electricity load. If they do, then use the building's energy storage device and photovoltaic power to supply electricity to the building's electricity load; otherwise, determine the first electricity purchase information based on the total electricity load, the photovoltaic output, the converter conversion efficiency, and the first discharge power, and purchase electricity from the grid according to the first electricity purchase information.

[0061] In the above embodiments, such as Figure 2 As shown, the power supply method is determined based on the relationship between photovoltaic (PV) output (i.e., the electrical energy generated by the PV system) and the total electrical load (the electrical energy required by the building), as well as the characteristics of the energy storage device (such as maximum charging power, maximum discharging power, discharge efficiency, converter efficiency, etc.). First, if the target time period is the PV output period, and the PV output is large enough to at least equal the total electrical load, the system will first use PV power to supply the building's electrical load. Next, the system will consider the maximum charging power of the energy storage device, the current PV output, and the total electrical load to determine a suitable charging power (here called the first charging power). Then, the remaining PV power is used to charge the energy storage device at this first charging power. If there is still remaining PV power after the energy storage device has finished charging, this portion of the power will be fed into the power grid. On the other hand, if the target period is also a photovoltaic (PV) output period, but the PV output is less than the total electricity load, meaning the PV power is insufficient to meet the building's total electricity demand, the system will first determine a suitable discharge power (referred to as the first discharge power) based on the characteristics of the energy storage device (such as maximum discharge power, discharge efficiency, converter conversion efficiency, etc.), as well as the current PV output and total electricity load. Then, the system will determine whether this first discharge power and the current PV output are sufficient to meet the total electricity load demand. If sufficient, the building's electricity load will be supplied by both the energy storage device and PV power. If insufficient, the system will determine how much electricity needs to be purchased from the grid (referred to as the first electricity purchase information) based on the total electricity load, PV output, converter conversion efficiency, and the first discharge power, and will purchase electricity from the grid according to this first electricity purchase information to meet the building's electricity demand. By rationally utilizing PV power and energy storage devices, the system achieves power supply to the building during PV output periods and purchases electricity from the grid when necessary to compensate for power shortages.

[0062] In specific application scenarios, when p pv,i ≥p L,iAt that time, after meeting the total household load, the photovoltaic system charges the battery, and the remaining electricity is then fed into the grid. Building-to-Battery Charging Power

[0063] p essc,i (t)=min{p esscmax,i ,(p pv,i (t)-p L,i (t))η essc}

[0064] Where: p pv,i (t) represents the photovoltaic output of building i during time period t, p L,i (t) represents the total electrical load p of building i during time period t. esscmax,i Maximum charging power of building-integrated batteries (energy storage devices); η essc To improve battery charging efficiency.

[0065] When the battery is fully charged, the remaining photovoltaic energy is fed into the grid. At this time, the battery is not working, and the state of charge of the building's i-battery is:

[0066] λ SOC-ess,i (t)=λ SOC-ess,i (t-1)(1-γ)

[0067] Wherein: γ is the natural discharge rate of the battery when it is not working, which is 0.01 / day.

[0068] When p pv,i <p L,i When the battery is discharging, it will purchase electricity from the grid when the battery output is insufficient.

[0071] Where: p essdmax,i The maximum discharge power of the building's i-battery; η essd For battery discharge efficiency; η DC-DC The converter efficiency.

[0072] Building i purchases electricity from the power grid

[0073]

[0074] In this embodiment of the application, specifically, for periods without photovoltaic power output, step 102 includes:

[0075] Step 102-3: If the target time period is a non-photovoltaic output period and the electricity consumption period type is not an off-peak period, then the second discharge power of the energy storage device is determined based on the maximum discharge power of the energy storage device, the total electricity load, the discharge efficiency of the energy storage device, and the converter conversion efficiency of the energy storage device; it is determined whether the second discharge power meets the demand of the total electricity load. If it does, the energy storage device of the building is used to supply power to the electricity load of the building. Otherwise, the second electricity purchase information is determined based on the total electricity load, the converter conversion efficiency, and the second discharge power, and electricity is purchased from the grid according to the second electricity purchase information.

[0076] Step 102-4: If the target time period is a non-photovoltaic output period and the electricity consumption period type is an off-peak period, then the third electricity purchase information is determined based on the total electricity load, the converter conversion efficiency and the maximum charging power of the energy storage device, and electricity is purchased from the grid according to the third electricity purchase information. The electricity purchased from the grid is used to supply power to the building's electrical equipment and to charge the building's energy storage device.

[0077] In this embodiment, when the target time period is a non-photovoltaic output period and the electricity consumption period is not a low-price period (i.e., not when electricity prices are lowest), the system first checks the status of the energy storage device. It considers the maximum discharge power, discharge efficiency, and converter conversion efficiency of the energy storage device to determine a suitable discharge power, referred to here as the second discharge power. Then, the system determines whether this second discharge power can meet the building's current total electricity load demand. If the second discharge power is sufficient to meet the total electricity load, the system uses the energy storage device to supply power to the building's load. If the second discharge power is insufficient to meet the total electricity load, the system determines, based on the total electricity load, converter conversion efficiency, and second discharge power, how much more electricity needs to be purchased from the grid (referred to here as the second electricity purchase information). Subsequently, the system purchases electricity from the grid based on this second electricity purchase information to compensate for the insufficient discharge power of the energy storage device, ensuring that the building's electricity demand is met.

[0078] On the other hand, if the target time period is still a non-PV output period, but the electricity consumption period type changes to off-peak hours (i.e., when electricity prices are lowest), the system will prioritize purchasing electricity from the grid. In this case, it will determine a suitable electricity purchase information based on the total electricity load, converter efficiency, and the maximum charging power of the energy storage device; this is referred to as the third electricity purchase information. The main purposes of this electricity purchase are twofold: first, to supply power to the building's electrical equipment; and second, to charge the energy storage device, taking advantage of the low electricity price period to reduce overall electricity costs. In summary, under different electricity consumption periods and non-PV output periods, the system formulates energy supply strategies based on the characteristics of the energy storage device and the total electricity load, including whether to use the energy storage device for discharge, whether to purchase electricity from the grid, and the determination of the amount to be purchased. This strategy aims to ensure that the building's electricity demand is met while minimizing electricity costs.

[0079] In specific application scenarios, during normal and peak periods when there is no photovoltaic output, the battery discharges the power. When the battery output is insufficient, the power is purchased from the grid.

[0083] During off-peak hours when there is no solar power output: households purchase electricity from the grid during this period, and batteries are charged during off-peak hours.

[0084] Building i-Grid Electricity Purchased

[0085] Optionally, in this embodiment of the application, the method further includes: calculating the average electricity load during off-peak hours and the electricity load during each off-peak hour based on the historical electricity consumption information of each building; dividing the off-peak hours with electricity load less than the average electricity load during the off-peak hours into the first off-peak hours, and dividing the remaining off-peak hours into the second off-peak hours. Step 102-4 includes: if the target time period is a non-photovoltaic output period and the target time period belongs to the first valley period, then determine the second charging power of the energy storage device based on the state of charge of the energy storage device at the beginning of the valley period, the state of charge of the energy storage device at the end of the preset valley period, the capacity of the energy storage device, the number of first valley periods, the maximum charging power of the energy storage device, and the conversion efficiency of the converter; determine the fourth electricity purchase information based on the total electricity load, the conversion efficiency of the converter, and the second charging power, and purchase electricity from the grid according to the fourth electricity purchase information, using the electricity purchased from the grid to power the electrical equipment in the building and to charge the energy storage device in the building; if the target time period is a non-photovoltaic output period and the target time period belongs to the second valley period. The third charging power of the energy storage device is determined based on the state of charge of the energy storage device at the beginning of the off-peak period, the state of charge of the energy storage device at the end of the first off-peak period, the capacity of the energy storage device, the number of second off-peak periods, the maximum charging power of the energy storage device, and the conversion efficiency of the converter. The fifth electricity purchase information is determined based on the total electricity load, the conversion efficiency of the converter, and the third charging power. Electricity is purchased from the grid according to the fifth electricity purchase information, and the electricity purchased from the grid is used to supply power to the electrical equipment in the building and to charge the energy storage device in the building. The state of charge of the energy storage device at the end of the first off-peak period is determined based on the state of charge of the energy storage device at the beginning of the off-peak period, the number of first off-peak periods, the second charging power, the charging efficiency of the energy storage device, and the capacity of the energy storage device.

[0086] In this embodiment, firstly, the system calculates the average electricity load of each building during off-peak hours and the specific electricity load for each off-peak hour based on the historical electricity consumption information of each building. Then, the system classifies off-peak hours with electricity loads lower than the average as the first off-peak hours, and the remaining off-peak hours as the second off-peak hours. This classification helps the system manage energy use in different off-peak hours more accurately. Next, the system determines the electricity purchase strategy based on the characteristics of the target time period and the status of the energy storage device. Specifically, if the target time period is a non-photovoltaic output period and belongs to the first off-peak hour, the system first determines the second charging power of the energy storage device based on a series of parameters (such as the state of charge of the energy storage device at the beginning of the off-peak hour, the state of charge of the energy storage device at the preset end of the off-peak hour, the capacity of the energy storage device, the number of first off-peak hours, the maximum charging power of the energy storage device, and the converter conversion efficiency). Subsequently, the system determines the amount of electricity to be purchased from the grid (i.e., the fourth electricity purchase information) based on the total electricity load, the converter conversion efficiency, and the second charging power, and then purchases electricity from the grid according to this information. The purchased electricity will be used to meet the building's electrical equipment needs and to charge energy storage devices.

[0087] If the target time period is a non-PV output period and falls within the second off-peak period, the system will determine the third charging power of the energy storage device based on another set of parameters (such as the state of charge of the energy storage device at the beginning of the off-peak period, the state of charge of the energy storage device at the end of the first off-peak period, the capacity of the energy storage device, the number of second off-peak periods, the maximum charging power of the energy storage device, and the converter efficiency). Similarly, the system will determine the fifth electricity purchase information based on the total electricity load, the converter efficiency, and the third charging power, and purchase electricity from the grid accordingly. The purchased electricity will also be used to meet the building's electricity demand and charge the energy storage device.

[0088] In both processes, the system also considers the charging efficiency and capacity of the energy storage devices to ensure that they can be charged at the appropriate time and provide sufficient power when needed. Simultaneously, by segmenting off-peak hours and implementing a power purchase strategy based on the status of the energy storage devices, the system can more effectively utilize low-cost electricity and reduce overall electricity costs.

[0089] Optionally, in this embodiment, determining the second charging power of the energy storage device based on the state of charge of the energy storage device at the beginning of the off-peak period, the state of charge of the energy storage device at the end of the preset off-peak period, the capacity of the energy storage device, the number of first off-peak periods, and the maximum charging power of the energy storage device includes: if the state of charge of the energy storage device during the target period is less than the state of charge of the energy storage device at the end of the preset off-peak period, determining the second charging power of the energy storage device based on the state of charge of the energy storage device at the beginning of the off-peak period, the state of charge of the energy storage device at the end of the preset off-peak period, the capacity of the energy storage device, the number of first off-peak periods, and the maximum charging power of the energy storage device; otherwise, not charging the energy storage device. The third charging power of the energy storage device is determined based on the state of charge (SBC) of the energy storage device at the start of the off-peak period, the SBC of the energy storage device at the end of the first off-peak period, the capacity of the energy storage device, the number of second off-peak periods, the maximum charging power of the energy storage device, and the conversion efficiency of the converter. This includes: if the SBC of the energy storage device is less than the SBC of the energy storage device at the end of the preset off-peak period during the target period, the third charging power of the energy storage device is determined based on the SBC of the energy storage device at the start of the off-peak period, the SBC of the energy storage device at the end of the first off-peak period, the capacity of the energy storage device, the number of second off-peak periods, the maximum charging power of the energy storage device, and the conversion efficiency of the converter; otherwise, the energy storage device is not charged.

[0090] In this embodiment, for the first off-peak period, the system determines the second charging power of the energy storage device based on the following conditions: if the state of charge (SOC) of the energy storage device is less than the SOC at the end of the preset off-peak period during the target period (i.e., the currently considered off-peak period), then the system begins calculating the charging power. This calculation comprehensively considers the SOC at the start of the off-peak period, the SOC at the end of the preset off-peak period, the total capacity of the energy storage device, the number of the first off-peak periods (i.e., how many such periods there are), and the maximum charging power of the energy storage device. If the SOC of the energy storage device has reached or exceeded the SOC at the end of the preset off-peak period, then the system will not charge the energy storage device to avoid overcharging or wasting energy. For the second off-peak period, the system determines the third charging power of the energy storage device based on the following conditions: similarly, if the SOC of the energy storage device is less than the SOC at the end of the preset off-peak period during the target period, the system begins calculating the charging power. This calculation additionally considers the converter's conversion efficiency to ensure more precise control of the charging process. If the state of charge (SBC) of the energy storage device has reached or exceeded a preset target, the system will not charge it. This strategy aims to ensure that the energy storage device can be effectively charged during off-peak hours, while avoiding overcharging and waste. By adjusting the charging power based on the real-time SBC of the energy storage device and the preset target, the system can manage energy more flexibly, improve energy efficiency, and reduce energy costs.

[0091] In specific application scenarios, operators use historical household electricity load data (p) during off-peak hours in buildings to determine the appropriate electricity consumption. L,i (t) is used for statistical analysis to obtain the average household electricity consumption p during off-peak hours. μ Statistical p L,i (t) <p μ The number of time periods is denoted as the first off-peak period N1, and the remaining time periods are denoted as N-N1 (the second off-peak period). The load demand is low during period N1 and high during period N-N1. The operator analyzes the charging demand uploaded by the battery. If the battery receives insufficient charging during period N1, it will be charged during the remaining time periods N-N1 of the off-peak period.

[0092] During the N1 time period, electricity is purchased from the grid to meet the total household load p. L,i (t) also charges the battery.

This indicates that the ESS will not be in both charging and discharging states simultaneously; λ SOC-essmin and λ SOC-essmax These represent the minimum and maximum states of charge (SOC) of the battery, respectively.
