[0025] The method embodiments provided in the embodiments of the present application can be executed in a computer terminal or a similar computing device. Taking running on a computer terminal as an example, Figure 1FIG. 1 is a hardware structure block diagram of a computer terminal of a frequency stabilization method according to an embodiment of the present application.

In one example, the transmission device 106 can be a radio frequency (Radio Frequency, referred to as RF) module, which is used to communicate with the Internet wirelessly.

[0028] In this embodiment, a frequency stabilization method is provided, which is applied to the above-mentioned computer terminal. Figure 2 is a flow chart of a frequency stabilization method according to an embodiment of the present application, such as Figure 2 As shown, the process includes the following steps:

[0029] Step S202, determining a frequency deviation of the power system according to frequency data of the power system, wherein the power system includes electric energy generated by renewable energy, and the frequency deviation is caused by fluctuations of the renewable energy;

[0030] Step S204, when the frequency deviation is greater than a preset value, determining the power adjustment amount of the electrolytic cell according to the frequency deviation and the number of electrolytic cells currently in operation, wherein the electrolytic cell is used to adjust the frequency of the power system;

[0031] Step S206, determining the first power of the i-th electrolyzer among the electrolyzers according to the power adjustment amount and the target output power of the electrolyzer, and allocating the first power to the i-th electrolyzer to stabilize the actual frequency of the power system, wherein i is a positive integer.

[0032] Through the above steps, the frequency deviation of the power system is determined according to the frequency data of the power system, wherein the power system includes electric energy generated by renewable energy, and the frequency deviation is caused by the fluctuation of the renewable energy; when the frequency deviation is greater than the preset value, the power adjustment amount of the electrolyzer is determined according to the frequency deviation and the number of electrolyzers currently in operation, wherein the electrolyzer is used to adjust the frequency of the power system; the first power of the i-th electrolyzer in the electrolyzer is determined according to the power adjustment amount and the target output power of the electrolyzer, and the first power is allocated to the i-th electrolyzer to stabilize the actual frequency of the power system, wherein i is a positive integer. This solves the problem in the related art that when the frequency of the power system fluctuates, the electrolyzer lacks flexibility in power adjustment of the power system, which easily leads to instability of the power system.

[0033] In an exemplary embodiment, determining the frequency deviation of the power system according to the frequency data of the power system includes: determining the frequency deviation according to the following formula : ,in, is the standard frequency of the power system, is the actual frequency, and the frequency data includes the standard frequency and the actual frequency.

[0034] When the actual frequency Equal to standard frequency When the frequency deviation 0, indicating that the power system frequency is in an ideal state, with supply and demand balanced. Lower than standard frequency , the frequency deviation obtained by this formula is If the actual frequency is negative, it means that the power system needs to increase power output to raise the frequency to the standard level. Higher than standard frequency , frequency deviation A positive value indicates that the power system should reduce power output to reduce the frequency to the standard level. It is set during the design and operation of the power system, usually 50 Hz or 60 Hz. The setting of standard frequency ensures that all equipment in the power system can operate in the best condition. Any deviation from the standard frequency may affect the performance and life of the equipment.

[0035] In an exemplary embodiment, determining the power adjustment amount of the electrolytic cell according to the frequency deviation and the number of electrolytic cells currently in operation includes: determining the power adjustment amount according to the following formula: : ,in, is the frequency regulation coefficient of the power system, is the frequency deviation, is the number of the electrolytic cells.

[0036] It should be made clear that It represents the total power value that needs to be increased or decreased when the electrolyzer array (i.e. all electrolyzers currently in operation) responds to the change in the power system frequency at time t. When it is a positive number, that is, the actual frequency is higher than the standard frequency, the total power adjustment of the electrolyzer array will increase, which means that the electrolyzer array needs to absorb more power to reduce the frequency of the power system; conversely, when When negative, the electrolyzer array reduces power absorption, or releases stored power to increase the frequency of the power system. The frequency regulation coefficient of the power system is a pre-set parameter used to adjust the intensity of the electrolyzer array's response to frequency deviations. The size of the frequency regulation coefficient determines the sensitivity of the electrolyzer array to frequency changes. A high value means that the electrolyzer array responds more strongly to frequency changes, can absorb or release electricity more quickly, and provides stronger support for the stable operation of the power system; a low value means that the electrolyzer array responds more strongly to frequency changes, can absorb or release electricity more quickly, and provides stronger support for the stable operation of the power system; A lower value means a gentler response, which may be suitable for smaller frequency changes, avoiding over-adjustment of the electrolyser power.

[0037] In an exemplary embodiment, determining the first power of the i-th electrolytic cell in the electrolytic cell according to the power adjustment amount and the target output power of the electrolytic cell includes: determining the first power according to the following formula: : ,in, is the target output power, is the power adjustment amount, is the flexibility weight of the i-th electrolyzer among the electrolyzers.

[0038] In determining the total additional power adjustment for the electrolyser array Afterwards, the flexibility weight of each electrolyzer The total adjustment is distributed to each electrolyzer in proportion. The power adjustment value of the i-th electrolyzer is is the target output power of the electrolyzer array Plus the additional power adjustment calculated based on the flexibility weight. This power allocation strategy based on flexibility weight ensures that the electrolyzers with the strongest adjustment capabilities in the electrolyzer array respond to the power adjustment requirements first, while those electrolyzers with weaker adjustment capabilities will receive corresponding power adjustment values ​​according to their weights.

[0039] In an exemplary embodiment, after allocating the first power to the i-th electrolyzer to stabilize the frequency of the power system, the method further includes: determining the second power of the i-th electrolyzer according to the following formula: : ,in, is the power recovery coefficient of the electrolytic cell, is the target output power; and the second power is distributed to the i-th electrolytic cell so that the output power of the i-th electrolytic cell is restored to a standard range.

[0040] When the frequency of the power system returns to normal, the operating power of the electrolyzer needs to be gradually restored to the standard range. The above formula calculates the target output power Compared with the actual operating power of the electrolyzer at the previous moment The difference between , and then multiply it by the power recovery factor of the electrolyzer , to determine the recovery increment of the electrolytic cell power. The second power of the electrolytic cell is the actual operating power at the last moment With restore increment It should be clear that the second power It represents the target power for the electrolyzer power to recover from the adjustment state in response to the frequency deviation in the power system to the normal operation state. represents the actual operating power of the ith electrolytic cell at the previous moment t-1, It reflects the latest status of the electrolyzer during the frequency adjustment process. is the power recovery coefficient of the electrolytic cell, which is used to control the speed of power recovery of the electrolytic cell. It determines the speed at which the electrolyzer recovers from the adjustment state to the target output power. A higher γ value means that the electrolyzer power recovers faster, while a lower γ value means that the electrolyzer power recovers slower.

[0041] In an exemplary embodiment, after allocating the first power to the i-th electrolytic cell to stabilize the frequency of the power system, the method further includes: again acquiring the frequency data of the power system after being stabilized by the i-th electrolytic cell to determine the frequency deviation; when the frequency deviation is still greater than the preset value, starting an alarm device set for the power system and generating an early warning report based on the actual frequency; encrypting the early warning report to obtain an encrypted early warning report; and transmitting the encrypted early warning report to a mobile device of a target object that maintains the power system to instruct the target object to detect the power system.

[0042] The frequency data of the power system is obtained again, and the frequency deviation between the real-time frequency and the standard frequency is calculated. If the frequency deviation still exceeds the preset value, it means that the frequency of the power system has not returned to normal and further intervention is required. When the frequency deviation is greater than the preset value, the alarm device is activated and an early warning report is generated. Among them, the alarm device includes but is not limited to an audible and visual alarm, which is used to immediately attract attention in the control center, and the early warning report contains detailed information such as the specific value of the frequency deviation, the power adjustment of the electrolyzer, and the recommended operation guide. In order to protect the security of the power system and the privacy of data, the early warning report needs to be encrypted before transmission to prevent unauthorized access and data leakage, and ensure that only authorized personnel can interpret the content of the report. The encrypted early warning report is transmitted to the mobile device of the target object responsible for maintaining the power system, such as a smartphone or tablet. Through instant communication of the mobile device, the target object can be quickly notified of the abnormal state of the power system and the response of the electrolyzer, so that they can take necessary detection and maintenance measures in time. After the mobile device receives the encrypted early warning report, the target object (usually the power system operation and maintenance personnel) can decrypt the report to understand the current state of the power system and the power adjustment of the electrolyzer. Based on this information, the target object can conduct detailed inspections of the power system to determine the specific causes of frequency deviations and take appropriate measures to adjust or repair them.

[0043] In an exemplary embodiment, after allocating the first power to the i-th electrolytic cell to stabilize the frequency of the power system, the method further includes: determining a power supply set for the alarm device, wherein the power supply is used to store electrical energy converted from solar energy; and when the remaining power of the alarm device is less than a preset threshold, starting the power supply to power the alarm device.

[0044] During the day or when there is sufficient sunlight, the solar panel converts the received solar energy into electrical energy, and charges the electrical energy into the energy storage battery through the power management module. When it is detected that the remaining power of the alarm device is lower than the preset threshold, it means that the battery of the alarm device is insufficient to support its operation for the next period of time, and additional power supply is required. Once the remaining power of the alarm device is lower than the preset threshold, the power management module provides power to the alarm device. In this way, even if the main power supply is interrupted or the power system is unstable, the alarm device can continue to operate by relying on the solar power supply system, ensuring that an early warning can be issued in time when the power system frequency is abnormal.

[0045] 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 it can also be implemented by hardware, but in many cases the former is a better implementation method. Based on this 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, disk, CD), 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.
