[0057] The accompanying drawings, which form part of this specification, are used to provide a further understanding of the invention. The illustrative embodiments of the invention and their descriptions are used to explain the invention and do not constitute an undue limitation of the invention. In the drawings:

[0058] Figure 1 This is a schematic diagram of a demand control method for load fluctuations caused by dual power supply, provided in Embodiment 1 of the present invention. Detailed Implementation

[0059] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. It should be noted that, without limitation, the embodiments and features described in the embodiments of the present invention can be combined with each other.

[0060] The following detailed description is exemplary and intended to provide further detailed explanation of the invention. Unless otherwise specified, all technical terms used in this invention have the same meaning as commonly understood by one of ordinary skill in the art. The terminology used in this invention is for describing particular embodiments only and is not intended to limit the scope of exemplary embodiments according to the invention.

[0061] Example 1:

[0062] A demand regulation control method applicable to load fluctuations from dual power supplies is implemented through intelligent monitoring equipment, intelligent control system, and power regulation system, wherein:

[0063] Intelligent monitoring equipment includes smart data acquisition meters, used to monitor the real-time load and maximum monthly demand of each circuit in the dual power supply system;

[0064] The intelligent control system is used to collect, analyze, assess, and control power data. Based on a pre-set optimization strategy algorithm model, it executes control commands and adjusts and optimizes the control strategy.

[0065] The power regulation system includes electrical load equipment, energy storage system, regulation and switching system and power control module, which is used for demand control of dual power supply system.

[0066] First, the existing dual-power supply system is upgraded to establish a basic power regulation capability architecture. This method is applicable to users with two power supplies, forming a primary regulation architecture, and a dual-power supply regulation switching system is set up. The regulation switches under the regulation architecture are interlocked, and only one switch in the dual-power supply can connect the upper and lower levels to supply power.

[0067] Secondly, the intelligent monitoring equipment uploads the collected load power data and real-time demand data of each line to the intelligent control system; at the same time, the power regulation system uploads the battery capacity data and regulation capability to the intelligent control system; based on the load conditions of each line and the power regulation system, the intelligent control system determines the logical relationship between the demand threshold control requirements of each line and the current operating load of each line, and combined with the maximum demand of each line in the current month, the intelligent control system determines the charging and discharging demand requirements of each line and the demand reduction that needs to be carried out, and automatically switches the relationship of the regulation segment; at the same time, it monitors the status of the power regulation system to ensure that the power regulation system does not overcharge or over-discharge.

[0068] In this embodiment, the logical steps of the demand regulation control method applicable to load fluctuations from dual power supplies are as follows:

[0069] Step 1: Perform demand management on each of the dual power supply lines to determine the maximum peak power load for each line in the current month and the demand-side management target;

[0070] Step 2: Configure the architecture of the power regulation system under dual power supply to ensure that each power supply can share the power regulation system. Configure the charging and discharging lines and logic, power regulation capability and capacity in the power regulation system, and calculate the maximum adjustable capacity and regulation time under different regulation capabilities.

[0071] Step 3: Based on historical data from various sources and combined with base load, production plans, and other electricity consumption characteristics, generate monthly load forecast data based on the AI ​​big data model, preset the monthly demand targets for each source, and adjust the maximum demand required in real time by combining real-time load data and self-correction data.

[0072] Step 4: Based on the adjustable capacity, adjustable capability, and predicted demand, perform energy storage and discharge control to achieve the goal of maximum demand control;

[0073] Step 5: Optimize and adjust the system according to the demand-side management objectives.

[0074] The algorithm logic is as follows:

[0075] ① Set the demand targets for routes A and B that need to be controlled this month;

[0076] ② The system collects real-time load and the maximum demand for the current month. Based on historical data, it determines SmaxA (the maximum cumulative demand for user A's incoming line this month) and SmaxB (the maximum cumulative demand for user B's incoming line this month). If SmaxA > SmaxB, the demand adjustment for this month prioritizes A; otherwise, it selects B for adjustment. Subsequently, the maximum adjustable demand is calculated based on the daily load curve forecast and the energy storage discharge curve fitting, which serves as the preset demand target Sset for this month. The calculation formula is as follows:

[0077] Sset=P_peak-min(P_rated,E_available / T_hours)

[0078] In the formula: P_peak is the maximum value in the daily load curve, which is predicted by the load forecasting model (based on historical load data, weather, production plans, etc.); P_rated is the rated discharge power of the energy storage system; E_available is the current available energy of the energy storage system; T_hours is the duration of the peak load.

[0079] ③ The system collects the current battery capacity status of the energy storage system and the current time period, determines the discharge capacity and power, as well as the charging time and power, and determines whether the charging power exceeds the preset demand target, and controls the charging power to avoid exceeding the control demand.

[0080] ④ When the system determines that the load is concentrated during a certain period, it determines whether the maximum demand of A / B channels and the set demand exceed the threshold set for this month, and adjusts the energy storage output control switch to the A / B channel switch position to control the energy storage system to perform standby or output state.

[0081] ⑤ When the system determines that the energy storage system needs to discharge to reduce demand, it intelligently switches to the A / B output based on the relationship between the set value and the maximum value, determines the output power of the energy storage system, controls the output power of the energy storage system inverter, and ensures that the demand is within a controllable range.

[0082] ⑥ Real-time output of system control demand curves, discharge power curves, energy storage system SOC curves, etc.

It then determines whether Trt is within the current settlement month and falls during off-peak hours, and the current capacity of the energy storage system. If C = 100%, the system enters standby mode; otherwise, it calculates the maximum required charging power.

[0086] Demand Smax ≤ target demand Sset, and current real-time demand Srt < Sset, when the maximum charging power Pin max of the energy storage inverter ≤ Sset - Srt:

[0087] Determine if the energy storage circuit is on the preset line, adjust it to the target position in time, and set the energy storage system charging power Pin = Pin max; determine the battery capacity status until C = 100%;

[0088] Determine whether the energy storage circuit is on the preset line and adjust it to the target position in time; set the energy storage system charging power Pin = Smax - Srt; and determine the battery capacity status until C = 100%.

[0089] 2) The maximum cumulative demand Smax this month is greater than the target demand Sset, and the current real-time demand Srt is less than Smax. When the maximum charging power Pinmax of the energy storage inverter is less than or equal to Smax - Srt:

[0090] Determine whether the energy storage circuit is on the preset line and adjust it to the target position in time; set the charging power of the energy storage system to Pin = Pin max; and determine the battery capacity status until C = 100%.

[0091] Determine whether the energy storage circuit is on the preset line and adjust it to the target position in time; set the energy storage system charging power Pin = Smax - Srt; and determine the battery capacity status until C = 100%.
