Description

Technical Field

[0001] The present application relates to the technical field of power systems, and in particular to a method and device for determining a load instruction, a storage medium, and an electronic device. Background Art

[0002] With the high proportion of new energy and power electronic equipment connected to the power system, the inertia and frequency stability of the power grid are further weakened. Traditional frequency regulation uses thermal power units as the main frequency regulation resource, but the response characteristics of thermal power units are poor and it is difficult to cope with the minute-level frequency regulation requirements of the new power system.

[0003] Research from the Pacific Northwest National Laboratory (PNNL) in the United States shows that 1MW of ideal regulation resources can replace the frequency regulation capacity of several MW of thermal power units. The water electrolysis hydrogen production system (i.e., hydrogen production device) has strong adaptability to power fluctuations and can achieve a second-level response to input power. It is coupled with a thermal power plant and, as a highly adjustable ideal flexibility resource, can participate in the peak and frequency regulation services of the thermal power plant. However, although the hydrogen production system has excellent regulation performance, its regulation range is constrained by the installed capacity and the system energy of the equipment itself, and it is an energy-limited regulation resource.

[0004] Combining the capacity advantages of thermal power units and the regulatory performance advantages of hydrogen production systems can improve the overall regulation capabilities of the system, but there is currently a lack of coordinated frequency regulation solutions that can combine the capacity advantages of thermal power units and the regulatory performance advantages of hydrogen production systems.

[0028] In this embodiment, a method for determining a load instruction is provided, which is applied to the above-mentioned computer terminal. Figure 2 is a flow chart of a method for determining a load instruction according to an embodiment of the present application, the flow chart comprising the following steps:

[0029] Step S202, obtaining an automatic power generation control signal at the current moment, and obtaining a signal sequence corresponding to the automatic power generation control signal;

[0030] It is understandable that the acquired automatic generation control signal (AGC) at the current moment and the automatic generation control signal within a preset time period before the current moment form a signal sequence. Optionally, the preset time period may be within the first 24 hours of the current moment.

[0031] Step S204, filtering the signal sequence through a preset filter to obtain a low-frequency load signal corresponding to the signal sequence;

[0032] Specifically, a first-order infinite impulse response (IIR) filter with a cutoff frequency of fc=1 / 60 Hz is used to perform low-pass filtering on the AGC signal sequence, and the low-frequency load signal after the current filtering is calculated.

[0033] Step S206, determining a first actual response signal change amount of the hydrogen production device and a second actual response signal change amount of the coal-fired unit through the automatic power generation control signal and the low-frequency load signal;

[0034] Step S208: determining a first load instruction of the hydrogen production device and the coal-fired unit according to the first actual response signal change amount and the second actual response signal change amount.

[0035] It should be noted that a hydrogen production device is a device that uses hydropower or other renewable energy to produce hydrogen. Water is decomposed into hydrogen and oxygen through electrolysis or other chemical reactions, and the generated hydrogen is then used for fuel cell power generation or directly supplied as fuel to fuel cell vehicles and other applications. The hydrogen production system plays an important role in the field of power generation. It can achieve the production and utilization of clean energy, reduce dependence on traditional fossil energy, and reduce carbon emissions and environmental pollution.

[0036] Through the above steps, the automatic power generation control signal at the current moment is obtained, and the signal sequence corresponding to the automatic power generation control signal is obtained; the signal sequence is filtered through a preset filter to obtain a low-frequency load signal corresponding to the signal sequence; the first actual response signal change of the hydrogen production device is determined by the automatic power generation control signal and the low-frequency load signal, and the second actual response signal change of the coal-fired unit is determined; the first load instruction of the hydrogen production device and the coal-fired unit is determined by the first actual response signal change and the second actual response signal change. Through the above embodiments, the problem of the lack of a coordinated frequency regulation solution that combines the capacity advantages of thermal power units and the regulation performance advantages of hydrogen production systems in related technologies is solved, and the technical effect of determining the first load instruction and then coordinated frequency regulation is achieved.

[0037] In an exemplary embodiment, a first actual response signal change amount of the hydrogen production device is determined by the automatic power generation control signal and the low-frequency load signal, including: determining a response signal that requires the hydrogen production device to respond by the automatic power generation control signal and the low-frequency load signal; determining an adjustable load range of the hydrogen production device; and determining the first actual response signal change amount by the response signal and the adjustable load range.

[0038] The step of determining the response signal to which the hydrogen production device needs to respond by using the automatic power generation control signal and the low-frequency load signal includes: taking the difference between the automatic power generation control signal and the low-frequency load signal as the response signal to which the hydrogen production device needs to respond.

[0039] Furthermore, in some optional embodiments, determining the adjustable load range of the hydrogen production device includes: determining the operating load of the hydrogen production device at the current moment; and obtaining the upper load limit and the lower load limit of the hydrogen production device; determining a first difference between the upper load limit and the operating load, and determining a second difference between the operating load and the lower load limit; and determining the adjustable load range through the first difference and the second difference.

[0040] In some optional embodiments, the first actual response signal change amount is determined by the response signal and the adjustable load range, including: when the response signal is greater than the target value, the first actual response signal change amount is determined by the response signal and the lower limit of the adjustable load range; when the response signal is less than the target value, the first actual response signal change amount is determined by the response signal and the upper limit of the adjustable load range.

[0041] It is understandable that the response signal is compared with the target value. If the response signal is greater than the target value, the first actual response signal change is determined by the response signal and the lower limit of the adjustable load range; if the response signal is less than the target value, the first actual response signal change is determined by the response signal and the upper limit of the adjustable load range. Optionally, the target value is 0.

[0042] Furthermore, the first actual response signal change is determined by the response signal and the lower limit of the adjustable load range, including: if the response signal is greater than or equal to the lower limit of the range, the first actual response signal change is equal to the opposite of the lower limit of the range; if the response signal is less than the lower limit of the range, the first actual response signal change is equal to the opposite of the response signal.

[0043] Furthermore, the first actual response signal change is determined by the response signal and the upper limit of the adjustable load range, including: if the response signal is greater than or equal to the upper limit of the range, the first actual response signal change is equal to the upper limit of the range; if the response signal is less than the upper limit of the range, the first actual response signal change is equal to the response signal.

[0044] In an exemplary embodiment, determining the second actual response signal change of the coal-fired unit includes: determining a third difference between the automatic power generation control signal and the first actual response signal change; and determining the third difference as the second actual response signal change.

[0045] In an exemplary embodiment, a first load instruction for the hydrogen production device and the coal-fired unit is determined by the first actual response signal change and the second actual response signal change, including: determining a second load instruction for the hydrogen production device at a moment before the current moment, and determining a third load instruction for the coal-fired unit at the moment before the current moment; determining a first sum of the second load instruction and the first actual response signal change, and determining a second sum of the third load instruction and the second actual response signal change; and determining the first sum and the second sum as the first load instruction.

[0046] Therefore, the embodiment of the present application determines the latest load instruction through the load instruction of each device in the hydrogen production device and the coal-fired unit at the previous moment and the actual response signal change of each device, and sends it to the hydrogen production device and the coal-fired unit to guide their power generation or hydrogen production load at the current moment. In this way, through continuous AGC signal adjustment, the load distribution of the hydrogen production system and the coal-fired unit can be optimized in real time to achieve more effective frequency control and power system stability, so as to improve the efficiency and flexibility of power grid frequency regulation.

[0047] In order to better understand the process of the above-mentioned method for determining the load instruction, the above-mentioned method for determining the load instruction is described below in combination with an optional embodiment, but it is not used to limit the technical solution of the embodiment of the present application.

[0048] In an optional embodiment of the present application, a method for determining a load instruction is as follows: Figure 3 As shown, including:

[0049] Step 1: Calculate the adjustable load range of the hydrogen production unit based on the current operating load.

[0050] 1) Obtaining AGC(t) up to the current moment (i.e., the automatic power generation control signal in the above embodiment), and forming a signal sequence with the AGC signal within the previous 24 hours, with a data frequency of 5S;

[0051] 2) Calculate the adjustable load range ΔPh_up(t) and ΔPh_down(t) according to the current operating load of the hydrogen production device:

[0052] ΔPh_up(t)=Ph_max-Ph(t), ΔPh_down(t)=Ph(t)-Ph_min;

[0053] Among them, Ph_max represents the upper limit of the load of the hydrogen production device, Ph_min represents the lower limit of the load of the hydrogen production device, and Ph(t) represents the current load of the hydrogen production device (that is, the operating load at the current moment in the above embodiment).

[0054] Step 2: Use a first-order infinite impulse response (IIR) filter with a cutoff frequency of fc = 1 / 60 Hz to low-pass filter the AGC signal sequence and calculate the current filtered low-frequency load P_Lowfreq(t) signal;

[0055] Step 3: Calculate the actual response signal of the hydrogen production device;

[0056] Step 4: Calculate the actual response signal of the coal-fired unit.

[0057] For the above steps 3 and 4, the specific implementation methods include:

[0058] 1) Calculate the required hydrogen production device response signal ΔPh_demand(t);

[0059] ΔPh_demand(t)=AGC(t)-P_Lowfreq(t);

[0060] 2) calculating the actual response signal change amount ΔPh(t) of the hydrogen production device (equivalent to the first actual response signal change amount in the above embodiment);

[0061] When ΔPh_demand(t)>0:

[0062] If ΔPh_demand(t)≥ΔPh_down(t), ΔPh(t)=-(ΔPh_down(t));

[0063] If ΔPh_demand(t)<ΔPh_down(t), ΔPh(t)=-(ΔPh_demand(t));

[0064] When ΔPh_demand(t)<0:

[0065] If ΔPh_demand(t)≥ΔPh_up(t), ΔPh(t)=ΔPh_up(t);

[0066] If ΔPh_demand(t)<ΔPh_up(t), ΔPh(t)=ΔPh_demand(t);

[0067] 3) Calculating the actual response signal change amount ΔPcoal(t) of the coal-fired unit (equivalent to the second actual response signal change amount in the above embodiment);

[0068] ΔPcoal(t)=AGC(t)-ΔPh(t);

[0069] 4) Output actual load instructions for hydrogen production system and coal-fired units;

[0070] Ph(t)=Ph(t-1)+ΔPh(t);

[0071] Pcoal(t)=Pcoal(t-1)+ΔPcoal(t);

[0072] Among them, Ph(t-1) represents the second load instruction of the hydrogen production device at the previous moment, and Pcoal(t-1) represents the third load instruction of the coal-fired unit at the previous moment.

[0073] Therefore, the optional embodiment of the present application provides a frequency regulation control strategy for the joint use of the water electrolysis hydrogen production system and the coal-fired unit, which decomposes the unit AGC instruction into high-frequency components and low-frequency components, and uses the coal-fired unit and the hydrogen production system to respond respectively, giving full play to the advantages of the two regulation resources. In other words, the optional embodiment of the present application decomposes the unit AGC instruction, wherein the high-frequency component is responded by the hydrogen production system and the low-frequency component is responded by the coal-fired unit, which can give full play to the rapid regulation capability of the hydrogen production system and the capacity advantage of the coal-fired unit, thereby obtaining a better frequency regulation result.

[0074] Through the description of the above implementation methods, those skilled in the art can clearly understand that the method according to the above embodiment can be implemented by means of software plus a necessary general hardware platform, and of course by hardware, but in many cases the former is a better implementation method. Based on such an understanding, the technical solution of the present application, or the part that contributes to the prior art, can be embodied in the form of a software product, which is stored in a storage medium (such as ROM / RAM, magnetic disk, optical disk), and includes a number of instructions for a terminal device (which can be a mobile phone, computer, server, or network device, etc.) to execute the methods of each embodiment of the present application.

[0075] The present application also provides a structural block diagram of a load instruction determination device. Figure 4 is a structural block diagram of a device for determining a load instruction according to an embodiment of the present application; Figure 4 As shown, including:

[0076] An acquisition module 42 is used to acquire the automatic power generation control signal at the current moment and acquire a signal sequence corresponding to the automatic power generation control signal;

[0079] Specifically, a first-order infinite impulse response (IIR) filter with a cutoff frequency of fc=1 / 60 Hz is used to perform low-pass filtering on the AGC signal sequence, and the low-frequency load signal after the current filtering is calculated.

Through the above embodiment, the problem of the lack of a coordinated frequency regulation solution that combines the capacity advantages of thermal power units and the regulation performance advantages of hydrogen production systems in related technologies is solved, and the technical effect of determining the first load instruction and then coordinated frequency regulation is achieved.

[0083] In an exemplary embodiment, the first determination module 46 is further used to: determine a response signal that requires the hydrogen production device to respond through the automatic power generation control signal and the low-frequency load signal; determine an adjustable load range of the hydrogen production device; and determine a change in the first actual response signal through the response signal and the adjustable load range.

[0084] The step of determining the response signal to which the hydrogen production device needs to respond by using the automatic power generation control signal and the low-frequency load signal includes: taking the difference between the automatic power generation control signal and the low-frequency load signal as the response signal to which the hydrogen production device needs to respond.

[0085] In an exemplary embodiment, the first determination module 46 is also used to: determine the operating load of the hydrogen production device at the current moment; and obtain the upper and lower load limits of the hydrogen production device; determine a first difference between the upper load limit and the operating load, and determine a second difference between the operating load and the lower load limit; determine the adjustable load range through the first difference and the second difference.

[0086] In an exemplary embodiment, the first determination module 46 is further used to: when the response signal is greater than the target value, determine the first actual response signal change amount through the response signal and the lower limit of the adjustable load range; when the response signal is less than the target value, determine the first actual response signal change amount through the response signal and the upper limit of the adjustable load range.

[0087] It is understandable that the response signal is compared with the target value. If the response signal is greater than the target value, the first actual response signal change is determined by the response signal and the lower limit of the adjustable load range; if the response signal is less than the target value, the first actual response signal change is determined by the response signal and the upper limit of the adjustable load range. Optionally, the target value is 0.

[0088] Furthermore, the first actual response signal change is determined by the response signal and the lower limit of the adjustable load range, including: if the response signal is greater than or equal to the lower limit of the range, the first actual response signal change is equal to the opposite of the lower limit of the range; if the response signal is less than the lower limit of the range, the first actual response signal change is equal to the opposite of the response signal.

[0089] Furthermore, the first actual response signal change is determined by the response signal and the upper limit of the adjustable load range, including: if the response signal is greater than or equal to the upper limit of the range, the first actual response signal change is equal to the upper limit of the range; if the response signal is less than the upper limit of the range, the first actual response signal change is equal to the response signal.

[0090] In an exemplary embodiment, the first determination module 46 is further configured to: determine a third difference between the automatic power generation control signal and the first actual response signal change; and determine the third difference as the second actual response signal change.

[0092] Therefore, the embodiment of the present application determines the latest load instruction through the load instruction of each device in the hydrogen production device and the coal-fired unit at the previous moment and the actual response signal change of each device, and sends it to the hydrogen production device and the coal-fired unit to guide their power generation or hydrogen production load at the current moment. In this way, through continuous AGC signal adjustment, the load distribution of the hydrogen production system and the coal-fired unit can be optimized in real time to achieve more effective frequency control and power system stability, so as to improve the efficiency and flexibility of power grid frequency regulation.
