Description

Power supply methods, systems, devices, electronic equipment and storage media

[0001] This application claims priority to Chinese Patent Application No. 202510291631.1, filed on March 12, 2025, entitled "Power Supply Method, System, Apparatus, Electronic Device and Storage Medium", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of generator power supply technology, and in particular to a power supply method, system, device, electronic equipment and storage medium. Background Technology

[0003] Currently, large generator sets are typically used as independent power sources to supply power to loads, such as large thermal power plants, hydropower plants, and large gas turbines. However, small generator sets, such as small gas turbines, gas internal combustion engines, and diesel engines, need to be connected to the power grid to supply power to loads in order to ensure the continuity of power supply.

[0004] Among them, when the generator set is connected to the grid, there is an operating mode of being connected to the grid but not connected to the grid. In this mode, all the electrical energy generated by the generator set is used to supply power to the load. It is not allowed to send electrical energy to the grid. The load is only allowed to absorb electrical energy from the grid. The output power of the generator set will be automatically adjusted according to the load of its own plant area. If the electrical energy generated by the generator set is sent to the grid, the anti-backfeeding device will cut off the generator set circuit breaker, which will affect the normal operation of the unit.

[0005] In the existing technology, when a generator set is operating in the above-mentioned grid-connected but not connected mode, if the generator set needs to manually adjust its output power due to insufficient fuel, and the adjusted output power is incorrect or the load suddenly decreases, it is easy for the generator set's output power to exceed the total load power, thereby causing the generator set to feed back power to the grid, affecting the normal operation of the generator set and reducing the user's economic benefits.

Furthermore, reference numerals and / or letters may be repeated in different examples.

[0072] To address the technical problem in existing technologies where, when a generator set operates in a grid-connected but not grid-connected mode, the generator set's output power exceeds the total load power, leading to back-discharge from the generator set to the grid, affecting normal operation and reducing user economic benefits, this application provides a power supply method, system, device, electronic equipment, and storage medium. During grid-connected operation of the generator module and grid module, due to the different power supply modes of the generator set, the target power output of the generator module can be determined in real time based on the generator set's power supply mode, the current total load power of the power supply system, and the current grid power supply of the grid module. Since the real-time determined target power output is always less than the total load power, it prevents situations where the generator module's power output exceeds the total load power due to misoperation or a sudden decrease in load power. This avoids the generator module transmitting power to the grid, ensuring continuous normal operation of the generator set and improving user economic benefits.

[0073] To facilitate understanding of the power supply method provided in this application, the following is an example of the power supply system involved in the method:

When the control module 11 is software, it can be installed in the aforementioned electronic devices.

[0076] The aforementioned generator module 12 may include at least one generator set, which may include, but is not limited to, generator sets such as small gas turbines, gas internal combustion engines, and diesel engines.

[0077] The aforementioned power grid module 13 refers to the power grid in the power supply system 10. It refers to the whole consisting of substations and transmission and distribution lines of various voltages in the power system. The power grid can include three units: substation, transmission, and distribution. Its task is to transmit and distribute electrical energy and change voltage.

[0078] The first current measuring module 14 and the second current measuring module 15 mentioned above both refer to modules used to measure current values. They can be current transformers or other modules used to measure current. The first current measuring module 14 and the second current measuring module 15 can be the same measuring module or different measuring modules. This application embodiment does not limit this.

[0081] The output terminals of the first current measurement module 14 and the first voltage measurement module 16 (output terminal O2 of the first current measurement module and output terminal O3 of the first voltage measurement module) are both connected to the input terminal I1 of the control module 11.

[0082] The output terminal O4 of the generator module 12 is connected to the input terminals of the second current measurement module 15 and the second voltage measurement module 17 (input terminal I5 of the second current measurement module 15 and input terminal I6 of the second voltage measurement module 17).

[0083] The output terminals of the second current measurement module 15 and the second voltage measurement module 17 (output terminal O5 of the second current measurement module 15 and output terminal O6 of the second voltage measurement module 17) are both connected to the input terminal I1 of the control module 11.

[0084] The output terminal O1 of the control module 11 is connected to the input terminal I4 of the generator module 12.

[0085] The output terminals of the aforementioned power grid module 13 and generator module 12 (output terminal O of power grid module 13 and output terminal O4 of generator module 12) are both connected to the load terminal I of power supply system 10.

[0086] The aforementioned control module 11 can be used to execute the power supply method provided in this application.

[0087] In this embodiment, the control module 11 can obtain the grid current and grid voltage of the grid module 13 through the first current measurement module 14 and the first voltage measurement module 16, thereby determining the grid power of the grid module 13 based on the grid current and grid voltage.

[0088] Meanwhile, the control module 11 can obtain the power generation current and power generation voltage of the generator module 12 through the second current measurement module 15 and the second voltage measurement module 17, and thus determine the power generation power of the generator module 12 based on the power generation current and power generation voltage.

[0089] In this embodiment, the control module 11 can adjust the current power generation of the generator set 13 through the power supply method provided in this application, determine the target power generation, and control the generator set 13 to generate power according to the target power generation. Since the determined target power generation is less than the total load power of the power supply system 10 in real time, it can prevent the generator module's power generation from exceeding the total load power due to misoperation or a sudden decrease in load power, thereby avoiding the generator module from transmitting power to the grid, ensuring the continuous normal operation of the generator set, and improving the user's economic benefits.

[0090] The power supply system provided in this application embodiment may include a control module, a generator module, a power grid module, a first current measurement module, a second current measurement module, a first voltage measurement module, and a second voltage measurement module.

The output terminal of the generator module can be connected to the input terminals of the second current measurement module and the second voltage measurement module, respectively. The output terminals of both the second current measurement module and the second voltage measurement module can be connected to the input terminal of the control module. The output terminal of the control module can be connected to the input terminal of the generator module. The output terminals of both the power grid module and the generator module can be connected to the load terminal of the power supply system. In this power supply system, through the above connection method, the control module can obtain the grid power of the grid module through the first current measurement module and the first voltage measurement module, and obtain the power generation power of the generator module through the second current measurement module and the second voltage measurement module, and control the power generation power of the generator module through the power supply method of this application. This can prevent the power generation power of the generator module from exceeding the total load power due to misoperation or sudden reduction in load power, thereby avoiding the generator module from transmitting power to the grid, ensuring the continuous normal operation of the generator set, and improving the economic benefits for users.

[0091] Further, referring to Figure 2, is a schematic diagram of another power supply system provided in an embodiment of this application. As shown in Figure 2, the first voltage measurement module 16 may include a voltage transformer 21 (hereinafter referred to as the first voltage transformer 21 for ease of description) and a safety device 22 (hereinafter referred to as the first safety device 22 for ease of description); the second voltage measurement module 17 may include a voltage transformer 23 (hereinafter referred to as the second voltage transformer 23 for ease of description) and a safety device 24 (hereinafter referred to as the second safety device 24 for ease of description).

[0092] Based on this, the first terminal P1 of the first safety device 22 can be connected to the output terminal O of the power grid module 13, the second terminal P2 of the first safety device 22 can be connected to the input terminal I21 of the first voltage transformer 21, and the output terminal O21 of the first voltage transformer can be connected to the input terminal I1 of the control module 11.

[0094] Optionally, the first safety device 22 and the second safety device 24 may be the same safety device or different safety devices. The safety device may be a fuse, a miniature circuit breaker, or other safety devices. This application embodiment does not limit this.

[0095] Optionally, when the generator module 12 is a low-voltage generator set connected to the power grid, the first voltage measurement module 16 may only include the first safety device 22, and the second voltage measurement module 17 may only include the second safety device 24.

[0096] Optionally, the first current measurement module 14 may be a first current transformer 25, and the second current measurement module 15 may be a second current transformer 26.

[0097] Optionally, the generator module 12 may include one or more generator sets.

[0098] Optionally, the power supply system 10 may further include a first switch module 27 and a second switch module 28.

[0101] The power supply method provided in this application will be further explained and described below with reference to the accompanying drawings and specific embodiments. The embodiments do not constitute a limitation on the embodiments of this application.

[0102] Referring to Figure 3, a flowchart of an embodiment of a power supply method provided in this application is shown. As an embodiment, the flowchart shown in Figure 3 can be applied to a control module in a power supply system, such as the control module 11 in the power supply system 10 shown in Figure 1. As shown in Figure 3, the flowchart may include the following steps:

[0103] Step 301: Determine the current power supply mode of the power supply system and the total load power corresponding to the current power supply system.

[0104] The aforementioned power supply system refers to a system used to supply power to a load. In this embodiment, the power supply system may include a control module, a generator module, and a grid module, such as the power supply system 10 shown in Figure 1. Furthermore, the generator module and grid module within this power supply system can operate in a grid-connected but not grid-connected mode. In this mode, all the electrical energy generated by the generator module is used to supply power to the load; power is not allowed to be supplied to the grid module. The load is only allowed to absorb electrical energy from the grid module, and the output power of the generator module can be automatically adjusted according to the load of its own plant area. If the electrical energy generated by the generator module is supplied to the grid, the backfeeding prevention device will disconnect the generator module circuit breaker, affecting the normal operation of the unit.

[0105] The aforementioned power supply modes refer to the current operating mode in which the power supply system supplies power to the load end, which may include, but is not limited to, power adaptive mode and constant power output mode. Specifically, the power adaptive mode means that the actual output power of the power grid can change according to the load variations of the power supply system; the constant power output mode means that the rated output power is set for the generator module and the grid mode so that the generator module and the grid module output electrical energy according to their corresponding rated power.

[0106] The total load power mentioned above refers to the total power required by the current load side of the power supply system.

[0107] In one embodiment, the user can set the power supply mode of the power supply system through the control module. Based on this, the control module can directly obtain the current power supply mode of the power supply system.

[0108] As an optional implementation, users can set the power supply mode of the power supply system through the visual interface of the control module. Based on this, the control module can obtain the current power supply mode of the power supply system through the visual interface.

[0109] In one embodiment, the control module can acquire the total load power of the power supply system in real time or at regular intervals.

[0110] As an optional implementation, power measurement devices can be connected between the control module and the generator module, as well as between the control module and the grid module. Based on this, the control module can measure the current grid power of the grid module and the current generating power of the generator module using the corresponding power measurement devices. Then, the grid power and generating power can be added together to obtain the current total load power of the power supply system.

[0111] As an exemplary implementation, as shown in FIG1, a first current measurement module and a first voltage measurement module can be connected between the control module and the power grid module, respectively. Based on this, the control module can obtain a first current value of the power grid module through the first current measurement module and a first voltage value of the power grid module through the first voltage measurement module. Then, the first current value and the first voltage value can be multiplied to obtain the power grid power of the power grid module.

[0112] Optionally, a second current measurement module and a second voltage measurement module can be connected between the control module and the generator module, respectively. Based on this, the control module can obtain the second current value of the generator module through the second current measurement module and the second voltage value of the generator module through the second voltage measurement module. Then, the second current value and the second voltage value can be multiplied to obtain the generator module's power output.

[0113] Step 302: Obtain the current grid power supply of the grid module under the above power supply mode.

[0114] The aforementioned power supply from the power grid refers to the current power supply of the power grid module. However, the power supply may vary depending on the power supply mode of the power supply system.

[0115] In this embodiment of the application, when the power supply system is in different power supply modes, the grid power supply power of its grid module may be different. Therefore, the control module can determine the current grid power supply power of the grid module according to the current power supply mode.

[0116] As an optional implementation, when the power supply system operates in power adaptive mode, the grid power supplied by the grid module follows the power output. In this case, the maximum load power included in the total load power and the power supply characteristic curve of the generator module can be obtained. Based on the maximum load power and the power supply characteristic curve, the current grid power supplied by the grid module is determined. The maximum load power refers to the load power corresponding to the largest load included in the total load power. The power supply characteristic curve characterizes the output power variation characteristics of the generator module, representing its load capacity response. Different generator modules may correspond to different power supply characteristic curves, meaning they have different load capacity responses. For example, the load capacity response of a gas internal combustion engine is less than that of a gas turbine, and the load capacity response of a gas turbine is less than that of a diesel internal combustion engine.

[0117] As an exemplary implementation, the instantaneous power change and time change of the generator module can be determined based on the power supply characteristic curve described above. Then, the current grid power supply of the grid module can be determined based on the maximum load power and the power change.

[0118] As one implementation method, the above-mentioned maximum load power can be subtracted from the above-mentioned variable power to obtain the current grid power supply of the grid module.

[0119] For example, suppose the maximum load power is 500kW, the generator module's output power is 1000kW, and the grid module's following power is 200kW, then the total power is 1200kW. Continuing, suppose the maximum load power of 500kW is instantly cut off within 1 second. Assuming the generator module can reduce its power by 200kW within that second, the remaining generating power is 800kW. However, the on-site load is only 700kW, meaning 100kW will be supplied to the grid module, causing a backfeed situation. Therefore, the grid module's grid supply power can be determined to be 300kW to prevent the generator module from supplying power to the grid module.

[0120] As another exemplary implementation, a current measurement module (e.g., the first current measurement module 14 shown in FIG. 1) and a voltage measurement module (e.g., the first voltage measurement module 16 shown in FIG. 1) can be connected between the control module and the power grid module, respectively. Based on this, the control module can obtain the current value of the power grid module through the current measurement module and the voltage value of the power grid module through the voltage measurement module. Then, the current value and the voltage value can be multiplied to obtain the power grid supply power of the power grid module.

[0121] As another optional implementation, when the power supply mode is a constant power output mode, the power grid module can have a manually set power grid setting value. At this time, the power grid module can be powered by the power grid setting value or other power. Therefore, the current power grid supply power of the power grid module can be directly obtained through the power measurement module.

[0122] As an exemplary implementation, a current measurement module (e.g., the first current measurement module 14 shown in FIG. 1) and a voltage measurement module (e.g., the first voltage measurement module 16 shown in FIG. 1) can be connected between the control module and the power grid module, respectively. Based on this, the control module can obtain the current value of the power grid module through the current measurement module and the voltage value of the power grid module through the voltage measurement module. Then, the current value and the voltage value can be multiplied to obtain the power grid supply power of the power grid module.

[0123] Step 303: Based on the above power supply mode, total load power, and grid power supply, determine the target power output of the generator module, and control the generator module to generate power according to the target power output, wherein the target power output is less than the total load power.

[0124] The aforementioned target power generation refers to the power generation of the generator module after the control module adjusts the power generation of the generator module according to the power supply mode, the total load power, and the power supply of the grid. This target power generation can be less than the total load power. Therefore, it can prevent the generator module from transmitting power to the grid in the event that the power generation of the generator module is greater than the total load power due to misoperation or a sudden decrease in load power.

[0125] In this embodiment, after determining the power supply mode of the power supply system, the corresponding total load power, and the grid power supply of the grid module, the control module can adjust the generator module's power generation based on the aforementioned power supply mode, total load power, and grid power supply to determine the generator module's target power generation. Then, the generator module can be controlled to supply power according to the target power generation. Since this target power generation is adjusted in real-time to be less than the total load power of the power supply system, controlling the generator module's power generation according to the target power generation prevents situations where the generator module's power generation exceeds the total load power due to misoperation or a sudden decrease in load power, thereby avoiding the generator module supplying electrical energy to the grid.

[0126] The specific method for determining the target power output of the generator module will be explained in the following sections using the flowcharts shown in Figures 4 and 5, and will not be detailed here.

[0127] The technical solution provided in this application determines the current power supply mode of the power supply system and the corresponding total load power of the power supply system. It then obtains the current grid power supply of the grid module under the aforementioned power supply mode. Based on the power supply mode, total load power, and grid power supply, it determines the target power generation of the generator module and controls the generator module to generate power according to the target power generation, wherein the target power generation is less than the total load power. This technical solution, during the grid-connected operation of the generator module and the grid module, allows for the determination of the target power generation of the generator module in real time based on the generator module's power supply mode, the current total load power of the power supply system, and the current grid power supply of the grid module, since the real-time determined target power generation is always less than the total load power. This prevents situations where the generator module's power generation exceeds the total load power due to misoperation or a sudden decrease in load power, thus avoiding the generator module supplying power to the grid and ensuring the continuous normal operation of the generator unit, thereby improving the user's economic benefits.

[0128] Referring to Figure 4, a flowchart of another power supply method provided in this application is shown. Based on the flowchart in Figure 3, Figure 4 describes how the target power output of the generator module is determined in the case of a power adaptive power supply mode.

[0129] As shown in Figure 4, the process may include the following steps:

[0130] Step 401: Determine the maximum power output of the generator module.

[0131] The aforementioned maximum power generation refers to the maximum power generation achieved by the generator module. Different generator modules may have different maximum power generation. For example, the maximum output power of a gas internal combustion engine may be the rated power of the unit, while the power of a gas turbine is subject to various limitations, such as temperature control and the opening of the fuel regulating valve. Therefore, the maximum output power of a gas turbine is not a fixed value, but rather the current power of the gas turbine when it reaches the limiting conditions.

[0132] In this embodiment of the application, when the control module determines the target power output of the generator module, it can obtain the maximum power output of the generator module.

[0133] As an optional implementation, the control module can pre-store the maximum power output of the generator module in a preset storage medium. Based on this, the control module can directly obtain the maximum power output of the generator module from the aforementioned storage medium.

[0134] Step 402: Determine the target power generation of the generator module based on the maximum power generation, total load power, and grid power supply.

[0135] The aforementioned total load power refers to the total power of the current load of the power supply system as determined in step 301.

[0136] The aforementioned power supply from the power grid refers to the current power supply of the power grid module within the power supply system as determined in step 301.

[0137] In this embodiment of the application, when the power supply system is operating in power adaptive mode, after determining the maximum power generation of the generator module, the control module can determine the target power generation of the generator module based on the maximum power generation, the total load power of the power supply system, and the power supply power of the grid.

[0138] As an optional implementation, the total load power can be subtracted from the grid power to obtain the remaining load power (hereinafter referred to as "first remaining load power" for ease of description).

[0139] Then, the maximum power generation capacity and the first remaining load capacity can be compared to obtain the comparison result.

[0140] Optionally, if the comparison results indicate that the maximum power generation is less than or equal to the first remaining load power, the target power generation of the generator module can be determined as the maximum power generation.

[0141] Optionally, if the comparison results indicate that the maximum power generation is greater than the first remaining load power, and the total load power is less than the grid power supply, it means that the grid power supply of the grid module meets the power supply requirements of the load. Therefore, the target power generation of the generator module can be determined as a preset value. This preset value can be a small power value, such as 0.

[0142] Optionally, if the total power of the load is greater than or equal to the power supplied by the grid, it means that the power supplied by the grid module cannot meet the power supply demand of the load, and the generator module needs to supply power to the load at the same time. Therefore, the target power of the generator module can be determined as the first remaining load power.

[0143] For example, suppose the power generation of the grid module to the load is 500kW (adjustable). This power is the following power. That is, if the maximum output power of the generator module is higher than the total load power, then the output power of the generator module can be the total load power minus the following power (500kW).

[0144] Therefore, in order to avoid excessive power generation of the generator module, when the maximum power generation of the generator module is less than or equal to the total load power minus 500kW, the target power generation of the generator module can be the aforementioned maximum power generation.

[0145] Optionally, when the maximum power output of the generator module is greater than the total load power - 500kW, if the total load power is less than 500kW, the target power output of the generator module can be determined to be 0.

[0146] Optionally, if the total load power is ≥500kW, the target power output of the generator module can be the total load power - 500kW, and this target power output can change at any time according to the load power.

[0147] The technical solution provided in this application determines the maximum generating power of the generator module and, based on the maximum generating power, the total load power, and the grid power supply, determines the target generating power of the generator module. This solution, by referencing the maximum generating power of the generator module and adjusting it according to the current total load power and grid power supply, allows for timely reduction of the generator module's generating power in case of misoperation or a sudden decrease in load power. This ensures that the generator module's generating power is always less than the total load power, preventing the generator module from supplying power to the grid module, thus guaranteeing the continuous and normal operation of the generator set and improving the user's economic benefits.

[0148] Referring to Figure 5, a flowchart of another embodiment of the power supply method provided in this application is shown. Based on the flowchart shown in Figure 3, Figure 5 describes how the target power output of the generator module is determined when the power supply mode of the power supply system is the electric power output mode. As shown in Figure 5, this process may include the following steps:

[0149] Step 501: Obtain the current initial power generation of the generator module.

[0150] The aforementioned initial power generation refers to the power generation of the generator module before adjustment.

[0151] In this embodiment of the application, before determining the target power generation of the generator module, the control module can first determine the current initial power generation of the generator module, and then adjust the initial power generation to determine the target power generation of the generator module.

[0152] As an optional implementation, a current measurement module (e.g., the second current measurement module 15 shown in Figure 1) and a voltage measurement module (e.g., the second voltage measurement module 17 shown in Figure 1) can be connected between the control module and the generator module, respectively. Based on this, the control module can obtain the current value of the generator module through the current measurement module and the current voltage value of the generator module through the voltage measurement module, and multiply the current value and the voltage value to obtain the current initial power generation of the generator module.

[0153] Step 502: Determine whether the initial power generation is greater than the grid power setting value. If yes, proceed to step 503; otherwise, proceed to step 504.

[0154] Step 503: Determine the target power generation of the generator module based on the total load power, the grid power setting value, and the power generation setting value.

[0155] Step 504: Determine the target power generation of the generator module based on the initial power generation and the power supplied by the grid.

[0156] The following provides a unified explanation of steps 502 to 504:

[0157] The aforementioned grid power setting value refers to the pre-set rated power generation value of the grid module.

[0158] The aforementioned power generation setting value refers to the pre-set rated power generation value of the generator module.

[0159] In this embodiment of the application, when the power supply mode of the power supply system is in the constant power output mode, the power grid module may have a preset power grid setting value, and the generator module may have a preset power generation setting value.

[0160] Based on this, after obtaining the current initial power generation of the generator module, the control module can first determine whether the initial power generation is greater than the grid power setting value of the grid module.

[0161] Optionally, if the initial power generation is greater than the grid power setting value, it indicates that the total load power of the power supply system is large and the power supply power of the generator module is greater than the grid power supply power of the grid module. In this case, the target power generation of the generator module can be determined based on the total load power, the grid power setting value, and the power generation setting value.

[0162] As an exemplary implementation, it can be determined whether the generator module has reached a preset maximum power limit condition. This maximum power limit condition characterizes the conditions under which the generator module reaches its maximum power output.

[0163] As one implementation method, if it is determined that the generator module has not reached the maximum power limit, it means that there is an adjustment range for the generator module at this time. Therefore, the total load power can be subtracted from the grid power setting value to obtain the remaining load power (hereinafter referred to as the second remaining load power for ease of description).

[0164] Then, the maximum power output of the generator module can be obtained (see the description in step 401 for details), and the minimum power value can be determined from the above power output setting value, the maximum power output, and the above second remaining load power, and the minimum power value can be determined as the target power output of the generator module.

[0165] As another implementation, if it is determined that the generator module has reached the maximum power limit condition, it means that the power generation of the generator module can no longer be adjusted. Therefore, the current initial power generation of the generator module can be determined as the target power generation of the generator module.

[0166] Optionally, if the initial power generation is less than or equal to the grid power setting value, it indicates that the total load power of the power supply system is small and the grid power supply of the grid module is greater than the power supply of the generator module. In this case, the target power generation of the generator module can be determined based on the initial power generation and the grid power supply.

[0167] As an exemplary implementation, it can be determined whether the initial power generation is greater than or equal to a preset initial power threshold, which is less than the grid power setting value. For example, when the grid power setting value is 500kW, the initial power threshold can be 200kW.

[0168] Optionally, if the initial power generation is determined to be greater than or equal to the initial power threshold, it can be determined whether the grid power supply is less than or equal to the aforementioned grid power setting value. If the grid power supply is determined to be less than or equal to the aforementioned grid power setting value, the target power generation of the generator module can be determined to be the initial power threshold; if the grid power supply is determined to be greater than the grid power setting value, the target power generation of the generator module can be determined to be the aforementioned grid power setting value.

[0169] For example, suppose the grid power provided by the grid module to the load is set to 500kW (adjustable), and the maximum power output of the generator module is 4000kW (adjustable).

[0170] As one implementation method, when the grid power generation is ≤500kW, if 200kW (initial power threshold) ≤ initial power generation ≤ 500kW, the target power generation of the generator module can be 200kW (adjustable within the range of 0-200kW).

[0171] Therefore, when the initial power generation is greater than 500kW, if the generator module reaches the maximum power limit, the target power generation will be the current initial power generation; if the generator module does not reach the maximum power limit:

[0172] Optionally, when the power generation setting value is less than or equal to the total load power - 500kW, if the power generation setting value is less than or equal to the maximum power generation value of 4000kW, then the target power generation value is the power generation setting value; if the power generation setting value is greater than the maximum power generation value of the generator module of 4000kW, then the target power generation value is the maximum power generation value of the generator module of 4000kW.

[0173] Optionally, when the power generation setting value is greater than the total load power - 500kW, if the power generation setting value is less than or equal to the maximum power generation value of 4000kW, then the target power generation value is equal to the total load power - 500kW; if the power generation setting value is greater than the maximum power generation value of 4000kW and the total load power - 500kW, then the target power generation value is equal to the total load power - 500kW; if the power generation setting value is greater than the total load power - 500kW and the maximum power generation value of 4000kW, then the target power generation value is equal to the maximum power generation value of 4000kW.

[0174] As another implementation method, when the grid power generation is greater than 500kW, if 200kW (initial power threshold) ≤ initial power generation ≤ 500kW, the target power generation is 500kW (adjustable within the range of 0-500kW).

[0175] Therefore, when the initial power generation is greater than 500kW, if the generator module reaches the limit, the target power generation is the current initial power generation; if the generator module does not reach the maximum power limit:

[0176] Optionally, when the power generation setting value is less than or equal to the total load power - 500kW, if the power generation setting value is less than or equal to the maximum power generation value of 4000kW, then the target power generation value is equal to the power generation setting value; if the power generation setting value is greater than the maximum power generation value of 4000kW, then the target power generation value is equal to the maximum power generation value of 4000kW.

[0177] Optionally, when the power generation setting value is greater than the total load power - 500kW, if the power generation setting value is less than or equal to the maximum power generation value of 4000kW, then the target power generation value is equal to the total load power - 500kW; if the power generation setting value is greater than the maximum power generation value of 4000kW and the total load power - 500kW, then the target power generation value is equal to the total load power - 500kW; if the power generation setting value is greater than the total load power - 500kW and the maximum power generation value of 4000kW, then the target power generation value is equal to the maximum power generation value of 4000kW.

[0178] The technical solution provided in this application obtains the current initial power output of the generator module and determines whether this initial power output is greater than the grid power setting value. If so, the target power output of the generator module is determined based on the total load power, the grid power setting value, and the generator power setting value. If not, the target power output of the generator module is determined based on the initial power output and the grid power supply. This technical solution, when the power supply system is operating in a constant power output mode, compares the current initial power output of the generator module with the pre-set grid power setting value of the grid module, and adjusts the initial power output of the generator module differently according to different comparison results. This adjusts the generator module's power output based on the different proportions of power supplied to the load by the generator module and the grid module, ensuring that the generator module's power output does not exceed the total load power even with different discharge power ratios of the generator module and the grid module. This guarantees the continuous normal operation of the generator unit and improves the user's economic benefits.
