DETAILED DESCRIPTION

[0012] In the following description, specific details such as specific system structures and technologies are provided for the purpose of illustration rather than limitation, so as to provide a thorough understanding of the embodiments of the present disclosure. However, it should be clear to those skilled in the art that the present disclosure may be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to avoid obstructing the description of the present disclosure with unnecessary details.

[0013] In order to make the purpose, technical solutions and advantages of the present disclosure more clear, specific embodiments will be described below in conjunction with the accompanying drawings.

[0014] refer to Figure 1 , Figure 1 A schematic diagram of the structure of a gas energy storage system provided in one embodiment of the present disclosure. The gas energy storage system includes a first power supply module, a second power supply module and a control module, and the first power supply module and the second power supply module are both connected to the control module. The first power supply module can be a containerized gas generator set, and the second power supply module can be a heat recovery power generation module. The first power supply module and the second power supply module are connected by a pipeline.

[0015] The input of containerized gas generator sets can be natural gas or industrial biogas; natural gas is a non-renewable resource, while industrial biogas comes from industrial processes and is a renewable resource. In the process of industrial production, abundant organic waste will be generated, which will eventually be converted into biogas. Gas generator sets can use biogas to generate electricity, and the generated electricity can be used as a backup resource to ensure the continuity and stability of industrial production, and can also form a virtuous cycle of waste treatment and energy production, promoting the development of a circular economy.

[0016] The working principle of the gas generator set is as follows: natural gas, industrial biogas and other gases are transported to the gas generator set in the container through pipelines or storage tanks. Before the gas enters the generator, it is filtered and pressure-regulated to ensure the purity and appropriate pressure of the gas. The treated gas is mixed with air and sent into the cylinder of the engine. The mixed gas quickly burns in the cylinder to produce high-temperature and high-pressure gas, which pushes the piston downward. The reciprocating motion of the piston is transmitted to the crankshaft through the connecting rod, causing the crankshaft to rotate. The generator connected to the crankshaft begins to rotate driven by the crankshaft. The coil inside the generator cuts the magnetic flux lines in the magnetic field. According to the principle of electromagnetic induction, induced electromotive force and induced current will be generated in the coil, thereby converting mechanical energy into electrical energy.

[0017] The generator generates heat during the power generation process. In order to maximize the energy conversion efficiency of the gas energy storage system, this application designs a heat recovery power generation module. The heat recovery power generation module can recover the heat generated during the operation of the generator and convert the heat into electrical energy for storage. The heat recovery power generation module is another module in the gas energy storage system that can generate electricity or perform secondary conversion of energy in addition to the first power supply module. It is a device that uses the waste heat generated by the gas generator set to generate electricity, such as an organic Rankine cycle power generation device, or other forms of energy conversion equipment.

[0018] refer to Figure 2 , Figure 2 This is a schematic diagram of the actual structure of the gas energy storage system provided in one embodiment of the present disclosure. Among them, the first power supply module is a gas generator set, and one gas generator set includes multiple generators. The heat recovery power generation module includes a waste heat boiler, a heat exchanger, a bromine machine, a waste heat conversion device, etc. The working principle of the whole system is: Natural gas or biogas is stored in the gas tank, which is transported to each generator through the gas pressure reducing station. The generator uses the heat generated by the combustion of combustible gases such as natural gas or biogas to generate electricity and transmit the electric energy to the first load. In order to reduce nitrogen oxide emissions and protect the environment and human health during the gas combustion process, denitrification equipment is also set up. Heat is generated during the power generation process of the gas generator set. Part of this waste heat enters the waste heat boiler and is converted into steam, and the other part is converted into hot water through the heat exchanger. The hot water can be used to recover bromine through the bromine machine equipment to achieve the purpose of waste recycling. The waste heat in the hot water and steam can generate a part of the electric energy after entering the waste heat conversion device (such as the organic Rankine cycle power generation device). The electric energy generated by the waste heat conversion device can be transmitted to the second load.

[0019] Please refer to Figure 3 , Figure 3 A flow chart of an operation control method of a gas energy storage system provided in an embodiment of the present disclosure, the method comprising: S101: Determine a target operation strategy based on a first load and a second load, where the first load is the load of a first power supply module and the second load is the load of a second power supply module.

[0020] In this embodiment, when the load of the first power supply module (i.e., the gas generator set) is the first load, the energy conversion efficiency of the gas generator set is the first energy conversion efficiency; when the load of the second power supply module (heat recovery power generation module) is the second load, the energy conversion efficiency of the heat recovery power generation module is the second energy conversion efficiency. When the first load and / or the second load suddenly increases, in order to improve the energy conversion efficiency of the gas energy storage system, it is necessary to determine the target operation strategy of the system in this scenario. For example, a plurality of operation strategies are stored in the system, corresponding to different first loads and second loads, respectively. When the first load increases from A kW to 2A kW, and the second load remains unchanged, the system uses the operation strategy corresponding to the optimal energy conversion efficiency under the load of 2AkW as the target operation strategy. The target operation strategy can be the specific values ​​of parameters such as the generator speed, the generator pressure, the output voltage, and the output current of the gas generator set in this scenario.

[0021] The target operation strategy is an operation plan formulated to enable the gas energy storage system to reach the highest load. This means that during the operation of the entire system, the chemical energy of the gas should be converted into electrical energy as efficiently as possible.

[0022] The target operation strategy includes adjusting the control parameters of the first power supply module and the second power supply module. The target operation strategy does not adjust the first power supply module or the second power supply module in isolation, but considers the mutual influence and collaborative work between the two modules from the perspective of the whole system.

[0023] For example, changes in the power output of the first power supply module will affect the amount and temperature of the waste heat it generates, which in turn affects the operation of the second power supply module. Therefore, when formulating the target operation strategy, it is necessary to comprehensively consider adjusting the control parameters of the two modules so that the entire gas energy storage system can achieve the highest energy conversion efficiency under different operating conditions (such as different power demand, gas quality, etc.).

[0024] S102: updating a first control parameter of a first power supply module based on a target operation strategy to obtain a first target control parameter; and controlling the first power supply module according to the first target control parameter.

[0025] In this embodiment, the first control parameter is a parameter for controlling the operating state of the gas generator set, including but not limited to power output control parameters, gas supply control parameters and power generation efficiency related parameters. The power output control parameters may include target power, power adjustment frequency, maximum output power, minimum output power, etc. The gas supply control parameters may include gas flow, gas pressure, etc. The power generation efficiency related parameters may include air-gas mixture ratio, combustion temperature, combustion pressure, exhaust gas temperature, etc.

[0026] The first power supply module, namely the gas generator set, is the main source of power supply, and its operating status directly determines the basic power output of the system. From the perspective of energy flow, the first power supply module is the starting link of energy conversion. Its operating status changes will trigger a series of chain reactions, including the waste heat flow and temperature changes generated, which will have a direct impact on the second power supply module. For example, an increase in the gas flow of the first power supply module will lead to an increase in the heat of the exhaust gas after combustion, and this waste heat is the energy source of the second power supply module. Therefore, the first control parameter of the first power supply module should be adjusted according to the target operation strategy first, so that the second control parameter of the second power supply module can be better adjusted according to its changes. After the second target control parameter is determined, the second power supply module can be controlled according to the second target control parameter.

[0027] The first control parameter of the first power supply module is updated based on the target operation strategy to obtain the first target control parameter, including: A first characteristic of the target operation strategy is determined, and a first control parameter of the first power supply module is determined according to the first characteristic.

[0028] The second characteristic of the target operation strategy is determined, and the first control parameter is updated according to the second characteristic to obtain the first target control parameter. The first characteristic is a characteristic matching the control parameter of the first power supply module, and the second characteristic is a set value of the control parameter corresponding to the first power supply module.

[0029] In this embodiment, there are many control parameters of the first power supply module, but each time it is updated, it is not necessary to update all the control parameters. The control parameters related to the target operation strategy, that is, the first control parameters, can be updated. The updated content can be the specific value of the parameter. First, according to the first feature of the target operation strategy, determine which parameters of the first power supply module need to be adjusted for this update; secondly, according to the second feature of the target operation strategy, determine what the specific adjustment method of these parameters is.

[0030] Controlling the first power supply module according to the first target control parameter includes: According to the change in the parameter value of the first target control parameter, the adjustment parameter in the PI control loop corresponding to the first target control parameter in the first power supply module is adjusted. The adjustment parameter includes a proportional adjustment parameter and an integral adjustment parameter.

[0031] Preferably, if the change in the parameter value of the first target control parameter is greater than or equal to the first preset change, the proportional adjustment parameter in the PI control loop corresponding to the first target control parameter in the first power supply module is adjusted; If the change in the parameter value of the first target control parameter is less than the first preset change, the integral adjustment parameter in the PI control loop corresponding to the first target control parameter in the first power supply module is adjusted.

[0032] The proportional adjustment parameter can make the parameter value of the first target control parameter quickly reach the set value in the target operation strategy; the integral adjustment parameter can make the parameter value of the first target control parameter slowly reach the set value in the target operation strategy.

[0033] Because when the change amount of the parameter value of the first target control parameter is greater than or equal to the first preset change amount, the parameter value needs to be quickly adjusted to the set value, so the proportional adjustment parameter is selected for adjustment. Because when the change amount of the parameter value of the first target control parameter is less than the first preset change amount, the parameter value needs to be slowly adjusted to the set value, so the integral adjustment parameter is selected for adjustment.

[0034] S103: updating a second control parameter of the second power supply module based on the first target control parameter to obtain a second target control parameter; and controlling the second power supply module according to the second target control parameter.

[0035] In this embodiment, the second control parameter is a parameter used to control the operating state of the heat recovery power generation module, including but not limited to temperature control parameters, flow control parameters, and heat recovery efficiency control parameters. Temperature control parameters may include heat source inlet temperature, heat recovery medium outlet temperature, etc.; flow control parameters may include heat recovery medium flow, exhaust gas flow, etc.; heat recovery efficiency control parameters include heat transfer temperature difference, fouling degree / pressure loss of heat exchanger, etc.

[0036] The second power supply module can be a heat recovery power generation module, which usually works in conjunction with the first power supply module. The second power supply module can use the high-temperature exhaust gas generated by the first power supply module for heat recovery power generation. By updating the second control parameter according to the first target control parameter, the second power supply module can better utilize the heat generated by the first power supply module. For example, when the exhaust temperature of the first power supply module increases due to the adjustment of the operating parameters, the second power supply module can more fully recover the waste heat for power generation after updating the flow and temperature control parameters of the heat recovery medium.

[0037] The second control parameter of the second power supply module is updated based on the first target control parameter to obtain the second target control parameter, including: Determining a second control parameter of the second power supply module based on the first target control parameter; The second control parameter is updated based on the target operation strategy to obtain a second target control parameter.

[0038] In this embodiment, the second power supply module includes many control parameters. When the control parameters of the first power supply module change, the control parameters of the second power supply module will also change. For example, if the first target control parameter increases the output power of the first power supply module, the waste heat (such as exhaust gas temperature and exhaust gas flow) generated by it will also increase accordingly. The second power supply module needs to determine the second control parameters of the second power supply module based on these energy changes.

[0039] The second control parameter may be some of the multiple control parameters of the second power supply module, and the second control parameter is directly related to the first target control parameter.

[0040] When the gas flow rate increases, the exhaust temperature of the first power supply module increases, and the heat source inlet temperature, heat recovery medium outlet temperature, heat recovery medium flow, exhaust gas flow, heat transfer temperature difference, etc. will all change. Therefore, according to the power generation power and gas flow rate, the second control parameter of the second power supply module can be determined as the heat source inlet temperature, heat recovery medium outlet temperature, heat recovery medium flow, exhaust gas flow, and heat transfer temperature difference. The value of the second control parameter is updated according to the load to obtain the final value, which is the second target control parameter.

[0041] Controlling the second power supply module according to the second target control parameter includes: According to the variation of the parameter value of the second target control parameter, the adjustment parameter in the PI control loop corresponding to the second target control parameter in the second power supply module is adjusted. The adjustment parameter includes a proportional adjustment parameter and an integral adjustment parameter.

[0042] Preferably, if the change in the parameter value of the second target control parameter is greater than or equal to the second preset change, the proportional adjustment parameter in the PI control loop corresponding to the second target control parameter in the second power supply module is adjusted; If the change in the parameter value of the second target control parameter is less than the second preset change, the integral adjustment parameter in the PI control loop corresponding to the second target control parameter in the second power supply module is adjusted.

[0043] The proportional adjustment parameter can make the parameter value of the second target control parameter quickly reach the set value in the target operation strategy; the integral adjustment parameter can make the parameter value of the second target control parameter slowly reach the set value in the target operation strategy.

[0044] Because when the change amount of the parameter value of the second target control parameter is greater than or equal to the second preset change amount, the parameter value needs to be quickly adjusted to the set value, so the proportional adjustment parameter is selected for adjustment. Because when the change amount of the parameter value of the second target control parameter is less than the second preset change amount, the parameter value needs to be slowly adjusted to the set value, so the integral adjustment parameter is selected for adjustment.

[0045] It can be concluded from the above that, on the one hand, the present disclosure can determine the optimal target operation strategy by comprehensively considering the load of the first power supply module and the second power supply module. Compared with the traditional fixed parameter control, it can more flexibly adapt to different energy supply and demand scenarios, thereby improving the operating efficiency and energy utilization of the entire gas energy storage system. This not only helps to reduce the operating cost of the system, but also reduces energy waste to a certain extent, and achieves greener and more sustainable energy utilization.

[0046] On the other hand, the present disclosure takes into account that the adjustment of the parameters of the first power supply module will affect the operating state of the second power supply module. Therefore, according to the target operation strategy, the control parameters of the first power supply module are first updated, and then the control parameters of the second power supply module are updated according to the control parameters of the first power supply module. This will help improve the stability and reliability of the system and reduce failures and safety hazards caused by improper parameters. At the same time, by continuously optimizing the control parameters, the response speed and adjustment ability of the system can be further improved, thereby improving the energy conversion efficiency of the gas energy storage system.

[0047] In one embodiment of the present disclosure, updating a second control parameter of a second power supply module based on a first target control parameter to obtain a second target control parameter includes: Determine a first ratio, the first ratio being a ratio between a first control parameter and a corresponding second control parameter; The second control parameter of the second power supply module is updated based on the first ratio and the first target control parameter to obtain a second target control parameter.

[0048] In this embodiment, the system needs to determine the proportional relationship between the first control parameter of the first power supply module and the second control parameter of the second power supply module, that is, the first ratio. The first ratio can be set based on factors such as design parameters, performance characteristics, and operating conditions of the two power supply modules, or it can be obtained through real-time measurement and calculation. This ratio reflects the association or coordination of the control parameters of the two power supply modules to ensure that they can cooperate with each other during operation and jointly meet the overall needs of the system.

[0049] After determining the first ratio, the system can update the second control parameter of the second power supply module according to the ratio and the first target control parameter of the first power supply module. For example, the exhaust gas flow rate (first control parameter) of the first power supply module is 8m³ / h, and the corresponding heat recovery medium flow rate (second control parameter) of the second power supply module is 2m³ / h, then the first ratio is 4. When the new exhaust gas flow rate is 12m³ / h, the heat recovery medium flow rate of the second power supply module is updated to: 12m³ / h×1 / 4=3m³ / h.

[0050] It can be concluded from the above that this embodiment achieves coordinated control between the two power supply modules by determining the proportional relationship between the first control parameter and the second control parameter and updating the control parameter of the second power supply module accordingly. This method can not only improve the overall operating efficiency of the system, but also ensure the coordinated operation between the modules, thereby improving the energy conversion efficiency.

[0051] In one embodiment of the present disclosure, updating a second control parameter of a second power supply module based on a first ratio and a first target control parameter includes: Calculating a first variation, where the first variation is a variation between a first target control parameter and a first control parameter; Determine a second change amount based on the first change amount and the first ratio, where the second change amount is a change amount of a second control parameter of the second power supply module; The second control parameter of the second power supply module is updated based on the second change amount.

[0052] In this embodiment, the first variation is used to measure the degree of change of the control parameter of the first power supply module from the original state to the target state. Because the operating parameters of the first power supply module have changed (from the first control parameter to the first target control parameter), this change will have an impact on the second power supply module. For example, the power output of the first power supply module is updated from the first power to the second power, and the first power is less than the second power. The increase is the first variation. By calculating the first variation, the degree of parameter adjustment of the first power supply module can be clearly understood.

[0053] The first ratio reflects the relative relationship between the control parameters of the first power supply module and the control parameters of the second power supply module. When the parameters of the first power supply module change (the first change), the change in the control parameters of the second power supply module (the second change) can be inferred based on the relationship (the first ratio). After determining the second change, the system can determine the updated second target control parameter based on the second change and the original second control parameter of the second power supply module. In this way, the control parameters of the second power supply module can be adjusted accordingly according to the changes in the first power supply module to adapt to the target operation strategy and ensure the coordinated operation between the two modules.

[0054] It can be concluded from the above that this embodiment achieves fine adjustment of the second control parameter by accurately calculating the change between the first target control parameter and the first control parameter and determining the change of the second power supply module control parameter according to the first ratio.

[0055] In one embodiment of the present disclosure, determining a target operation strategy based on a first load amount and a second load amount includes: Selecting a target operation strategy from a plurality of operation strategies of the control module based on the first load amount and the second load amount; Among them, different operation strategies correspond to different power supply modules.

[0056] In this embodiment, the operation strategy refers to a specific scheme for controlling the operation of the gas energy storage system. Each operation strategy contains a series of parameter settings and control instructions, which are used to specify the working mode of the first power supply module and the second power supply module, such as power output setting, gas flow control, heat recovery medium flow control, etc. Different operation strategies are suitable for different system requirements and working conditions. For example, one operation strategy may focus on maximizing power output during peak power consumption periods, while another operation strategy can improve energy conversion efficiency to save energy at low loads.

[0057] The target operation strategy is selected from multiple operation strategies stored in the control module and is the optimal solution for the current system operation. The target operation strategy is determined based on the first load and the second load, with the purpose of achieving the highest energy conversion efficiency for the entire gas energy storage system.

[0058] For example, if the second energy conversion efficiency is low under certain operating conditions, while the first energy conversion efficiency has the potential to be improved, the target operation strategy can be a solution that focuses on improving the energy utilization of the first power supply module and optimizes the performance of the entire system by adjusting relevant parameters.

[0059] Different operation strategies correspond to different power supply modules. Some operation strategies tend to adjust the control parameters of the first power supply module, some operation strategies tend to adjust the control parameters of the second power supply module, and some operation strategies can adjust multiple control parameters of the first power supply module and the second power supply module at the same time. Different operation scenarios and goals require different degrees of system control accuracy. For example, a simple operation strategy may only include two parameters: power output and gas flow, while a complex operation strategy includes, in addition to the above two parameters, the setting of multiple parameters such as combustion temperature, heat recovery medium temperature and flow.

[0060] The operation strategy of the control module includes a first operation strategy and a second operation strategy; the first operation strategy is used for the first power supply module, and the second operation strategy is used for the second power supply module; Selecting a target operation strategy from the operation strategies of the control module based on the first load and the second load includes: If the first load is greater than the first preset threshold and the second load is equal to or less than the second preset threshold, determining the target operation strategy to be the first operation strategy; If the second load is greater than the second preset threshold and the first load is equal to or less than the first preset threshold, determining the target operation strategy to be the second operation strategy; If the first load is greater than the first preset threshold and the second load is greater than the second preset threshold, the target operation strategy is determined to be the first operation strategy and the second operation strategy.

[0061] In this embodiment, when the first load is greater than the first preset threshold, it indicates that the control parameters of the first power supply module need to be adjusted, so that the first energy conversion efficiency can be improved. When the second load is greater than the second preset threshold, it indicates that the control parameters of the second power supply module need to be adjusted, so that the second energy conversion efficiency can be improved.

[0062] Because the first operation strategy is the operation strategy for the first power supply module, and the second operation strategy is the operation strategy for the second power supply module. Therefore, if the first load is greater than the first preset threshold, and the second load is equal to or less than the second preset threshold, it can be considered that the first power supply module is abnormal, and the control parameters of the first power supply module need to be adjusted to maximize the overall energy conversion efficiency of the system. If the second load is greater than the second preset threshold, and the first load is equal to or less than the first preset threshold, it can be considered that the second power supply module is abnormal, and the control parameters of the second power supply module need to be adjusted to maximize the overall energy conversion efficiency of the system. If the first load is greater than the first preset threshold, and the second load is greater than the second preset threshold, it can be considered that the first power supply module and the second power supply module are abnormal, and the control parameters of the first power supply module and the second power supply module need to be adjusted at the same time to maximize the overall energy conversion efficiency of the system.

[0063] In this embodiment, the first preset threshold can be determined according to the design specifications of each engine in the gas generator set, the degree of equipment aging, the energy cost and the pollution emission standard. The second preset threshold can be determined according to the heat recovery medium, the heat conversion efficiency, the heat recovery economic cost and the pollutant emission standard.

[0064] It can be concluded from the above that, by comparing the relationship between the first load and the second load and the preset threshold, the embodiment can select the optimal target operation strategy from different operation strategies. This selection mechanism not only improves the adaptability and flexibility of the energy conversion system, but also ensures that the system can maintain a high operating efficiency under different working conditions.

[0065] In one embodiment of the present disclosure, updating a first control parameter of a first power supply module based on a target operation strategy to obtain a first target control parameter includes: Extracting features of the target operation strategy to obtain target features; Calculating the matching degree between the target feature and each first control parameter, and determining the third control parameter from the plurality of first control parameters based on the arrangement order of the matching degrees; The third control parameter is updated to obtain the first target control parameter.

[0066] The target operation strategy includes the number of parameters; Determining a third control parameter from a plurality of first control parameters based on the arrangement order of the matching degrees includes: The first n matching degrees are selected from the order of arrangement of the matching degrees, and the third control parameter is determined from the plurality of first control parameters based on the first n matching degrees; wherein n is the number of parameters.

[0067] In this embodiment, feature extraction is performed on the target operation strategy to obtain target features, including: determining the target operation strategy effect words, segmenting the text in the target operation strategy to obtain multiple target words; Calculate the relevance of each target word and the target operation strategy effect word; The target feature is determined based on the relevance.

[0068] After determining the target feature, it is necessary to calculate the matching degree between the target feature and each first control parameter, and determine the third control parameter from multiple first control parameters based on the matching result. The target feature is a key indicator extracted from the target operation strategy, such as a specific power output range, gas flow rate, etc. The first control parameter is various parameters that control the operation of the first power supply module, such as actual output power, combustion temperature, etc. Calculating the matching degree is to find out to what extent each first control parameter meets the requirements set by the target feature.

[0069] For example, suppose the target feature is to require the first power supply module to increase the output power to 800kW within a certain period of time, and the first control parameter includes a parameter called power regulation rate. If the power regulation rate is 50kW per minute, then through certain calculations (for example, calculating the time required to reach the target power based on the current power, target power, and regulation rate), the matching degree between this power regulation rate and the target power increase requirement can be obtained. If the calculation result shows that the target power of 800kW can be reached within a suitable time according to this regulation rate, then the matching degree will be high; conversely, if the regulation rate is too slow and the target power cannot be reached in time, the matching degree will be low.

[0070] After calculating the matching degree between the target feature and each first control parameter, these matching degrees are arranged in descending order. This arrangement order can intuitively show the degree of fit between each first control parameter and the target feature. Then, the first n matching degrees are selected from the arrangement order of the matching degrees, and the third control parameter is determined from the multiple first control parameters based on the first n matching degrees.

[0071] In this embodiment, because there are multiple first control parameters, when adjusting the parameters according to the target operation strategy, not all control parameters need to be adjusted. Instead, according to the matching degree between the target characteristics in the target operation strategy and the first control parameters, the first n control parameters with the highest matching degree are selected for adjustment. This not only improves the pertinence and efficiency of the parameter adjustment, but also ensures that the adjusted control parameters can more accurately meet the requirements of the target operation strategy, thereby optimizing system performance, reducing unnecessary adjustment work, and improving the overall control effect and response speed.
