[0002] In today's society, the efficient use and rational allocation of energy have become crucial issues. Natural gas, as a vital energy source, plays an indispensable role in numerous aspects of industrial production and daily life. Gas energy storage systems, through specialized equipment and processes, can store gas under appropriate conditions and release and utilize it on demand. However, operational control of gas energy storage systems is crucial, and optimizing the system's energy conversion efficiency is a pressing issue. Summary of the Invention

[0021] In the following description, specific details such as specific system structures and techniques are provided for purposes of illustration rather than limitation to facilitate a thorough understanding of the embodiments of the present disclosure. However, it will be apparent 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 obscuring the description of the present disclosure with unnecessary detail.

[0022] In order to make the purpose, technical solutions and advantages of the present disclosure more clear, specific embodiments will be described below with reference to the accompanying drawings.

[0023] refer to Figure 1 , Figure 1 This is a schematic diagram of the structure of a gas energy storage system according to 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. Both the first and second power supply modules are 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 and second power supply modules are connected by pipelines.

[0024] Containerized gas-fired generator sets can be fed with either natural gas or industrial biogas. Natural gas is a non-renewable resource, while industrial biogas, derived from industrial processes, is a renewable resource. Industrial production generates abundant organic waste, which is ultimately converted into biogas. Gas-fired generator sets can utilize biogas to generate electricity, with the generated electricity serving as a backup resource. This ensures the continuity and stability of industrial production, creates a virtuous cycle of waste treatment and energy generation, and promotes the development of a circular economy.

[0025] The operating principle of a gas-fired generator set is as follows: natural gas, industrial biogas, or other fuels are delivered via pipelines or storage tanks to a gas-fired generator set within a container. Before entering the generator, the fuel undergoes filtration and pressure regulation to ensure purity and the appropriate pressure. The treated fuel gas is mixed with air and fed into the engine cylinder, where it rapidly combusts, producing high-temperature, high-pressure fuel gas that pushes the piston downward. The piston's reciprocating motion is transmitted to the crankshaft via a connecting rod, causing it to rotate. This drive then causes the generator, connected to the crankshaft, to rotate. The coils within the generator move in a magnetic field, cutting through magnetic lines of flux. Based on the principle of electromagnetic induction, this generates an induced electromotive force and current in the coils, converting mechanical energy into electrical energy.

[0026] 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 this 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.

[0027] refer to Figure 2 , Figure 2 This is a schematic diagram of the actual structure of the gas energy storage system provided by one embodiment of the present disclosure. The first power supply module is a gas generator set, which contains 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 operating principle of the entire system is as follows:

[0028] Natural gas or biogas is stored in gas tanks and delivered to generators via a gas pressure reducing station. The generators use the heat generated by the combustion of natural gas, biogas, or other combustible gases to generate electricity, which is then delivered to the first load. Denitrification equipment is also installed during the gas combustion process to reduce nitrogen oxide emissions and protect the environment and human health. The gas-fired generators generate heat during power generation. Part of this waste heat is converted into steam by a waste heat boiler, while the remaining heat is converted into hot water by a heat exchanger. The hot water is then used to recover bromine in a bromine generator, achieving waste recycling. The waste heat from the hot water and steam is then transferred to a waste heat conversion device (such as an organic Rankine cycle power generation device) to generate some electricity. The electricity generated by the waste heat conversion device is then delivered to the second load.

[0029] Please refer to Figure 3 , Figure 3 This is a flow chart of an operation control method for a gas energy storage system provided in one embodiment of the present disclosure, the method comprising:

[0030] 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.

[0031] In this embodiment, when the load of the first power supply module (i.e., the gas-fired generator set) is at the first load, the energy conversion efficiency of the gas-fired generator set is the first energy conversion efficiency. When the load of the second power supply module (the heat recovery power generation module) is at the second load, the energy conversion efficiency of the heat recovery power generation module is the second energy conversion efficiency. When the first and / or second loads suddenly increase, to improve the energy conversion efficiency of the gas-fired energy storage system, it is necessary to determine a target operating strategy for the system in this scenario. For example, the system stores multiple operating strategies corresponding to different first and second loads. When the first load increases from A kW to 2 A kW, while the second load remains unchanged, the system uses the operating strategy corresponding to the optimal energy conversion efficiency at a load of 2 A kW as the target operating strategy. The target operating strategy can be the specific values ​​of parameters such as the generator speed, generator pressure, output voltage, and output current of the gas-fired generator set in this scenario.

[0032] The target operation strategy is an operation plan formulated to maximize the load of the gas energy storage system. This means that during the entire system operation process, the chemical energy of the gas should be converted into electrical energy as efficiently as possible.

[0033] The target operation strategy includes adjusting the control parameters of the first and second power supply modules. Rather than adjusting the first or second power supply module in isolation, the target operation strategy considers the interaction and collaborative operation between the two modules from a system-wide perspective.

[0034] For example, changes in the power output of the first power supply module will affect the amount and temperature of 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 to ensure that the entire gas energy storage system achieves the highest energy conversion efficiency under different operating conditions (such as varying power demand and gas quality).

[0035] S102: Update a first control parameter of the first power supply module based on the target operation strategy to obtain a first target control parameter; and control the first power supply module according to the first target control parameter.

[0036] In this embodiment, the first control parameters are parameters used to control the operating state of the gas-fired generator set, including but not limited to power output control parameters, gas supply control parameters, and parameters related to power generation efficiency. Power output control parameters may include target power, power regulation frequency, maximum output power, minimum output power, etc. Gas supply control parameters may include gas flow rate and gas pressure, etc. Power generation efficiency parameters may include air-gas mixture ratio, combustion temperature, combustion pressure, exhaust gas temperature, etc.

[0037] The first power supply module, or the gas-fired generator set, is the primary power source, and its operating status directly determines the system's basic power output. From an energy flow perspective, the first power supply module is the starting point for energy conversion. Changes in its operating status trigger a series of chain reactions, including changes in waste heat flow and temperature, which directly impact the second power supply module. For example, an increase in gas flow in the first power supply module leads to an increase in the heat content of the exhaust gas after combustion, which serves as the energy source for the second power supply module. Therefore, adjusting the first control parameters of the first power supply module according to the target operating strategy first allows for better adaptation of the second control parameters of the second power supply module. Once the second target control parameters are determined, the second power supply module can be controlled accordingly.

[0038] Updating a first control parameter of the first power supply module based on the target operation strategy to obtain a first target control parameter includes:

[0039] A first characteristic of the target operation strategy is determined, and a first control parameter of the first power supply module is determined based on the first characteristic.

[0040] 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 that matches 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.

[0041] In this embodiment, the first power supply module has numerous control parameters. However, not all of these parameters need to be updated during each update. Instead, the control parameters associated with the target operating strategy, namely the first control parameters, can be updated. The updated parameters can be specific numerical values. First, based on the first characteristic of the target operating strategy, the parameters of the first power supply module that require adjustment are determined. Second, based on the second characteristic of the target operating strategy, the specific adjustment methods for these parameters are determined.

[0042] Controlling the first power supply module according to the first target control parameter includes:

[0043] The adjustment parameters in the PI control loop corresponding to the first target control parameter in the first power supply module are adjusted according to the change in the parameter value of the first target control parameter. The adjustment parameters include proportional adjustment parameters and integral adjustment parameters.

[0044] 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;

[0045] 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.

[0046] 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.

[0047] Because when the change in the parameter value of the first target control parameter is greater than or equal to the first preset change, 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 in the parameter value of the first target control parameter is less than the first preset change, the parameter value needs to be slowly adjusted to the set value, so the integral adjustment parameter is selected for adjustment.

[0048] S103: Update the second control parameter of the second power supply module based on the first target control parameter to obtain a second target control parameter; and control the second power supply module according to the second target control parameter.

[0049] In this embodiment, the second control parameters are 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 the heat source inlet temperature and the heat recovery medium outlet temperature; flow control parameters may include the heat recovery medium flow rate and exhaust gas flow rate; and heat recovery efficiency control parameters may include the heat transfer temperature difference, heat exchanger fouling level, and pressure loss.

[0050] The second power supply module can be a heat recovery power generation module, typically operating in conjunction with the first power supply module. The second power supply module can utilize the high-temperature exhaust gas generated by the first power supply module for heat recovery power generation. By updating the second control parameters based on the first target control parameters, the second power supply module can better utilize the heat generated by the first power supply module. For example, if the exhaust temperature of the first power supply module increases due to operating parameter adjustments, the second power supply module can update the flow and temperature control parameters of the heat recovery medium to more effectively recover the waste heat for power generation.

[0051] Updating a second control parameter of the second power supply module based on the first target control parameter to obtain the second target control parameter includes:

[0052] determining a second control parameter of the second power supply module based on the first target control parameter;

[0053] The second control parameter is updated based on the target operation strategy to obtain a second target control parameter.

[0054] In this embodiment, the second power supply module includes multiple control parameters. Changes in the control parameters of the first power supply module will also cause changes in the control parameters of the second power supply module. For example, if the first target control parameter increases the output power of the first power supply module, the waste heat generated (such as exhaust gas temperature and flow rate) will also increase accordingly. The second power supply module needs to determine its second control parameters based on these energy changes.

[0055] The second control parameter may be several 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.

[0056] When the gas flow rate increases, the exhaust temperature of the first power supply module rises, and changes occur in the heat source inlet temperature, heat recovery medium outlet temperature, heat recovery medium flow rate, exhaust gas flow rate, and heat transfer temperature difference. Therefore, based on the generated power and gas flow rate, the second control parameters of the second power supply module can be determined as the heat source inlet temperature, heat recovery medium outlet temperature, heat recovery medium flow rate, exhaust gas flow rate, and heat transfer temperature difference. The final values ​​of these second control parameters are updated based on the load, becoming the second target control parameters.

[0057] Controlling the second power supply module according to the second target control parameter includes:

[0058] The adjustment parameters in the PI control loop corresponding to the second target control parameter in the second power supply module are adjusted according to the change in the parameter value of the second target control parameter. The adjustment parameters include proportional adjustment parameters and integral adjustment parameters.

[0059] 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;

[0060] 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.

[0061] 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.

[0062] Because when the change in the parameter value of the second target control parameter is greater than or equal to the second preset change, 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 in the parameter value of the second target control parameter is less than the second preset change, the parameter value needs to be slowly adjusted to the set value, so the integral adjustment parameter is selected for adjustment.

[0063] As can be seen from the above, 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 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 costs of the system, but also reduces energy waste to a certain extent, achieving more green and sustainable energy utilization.

[0064] On the other hand, the present disclosure takes into account that adjusting 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 based on the control parameters of the first power supply module. This helps to 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 system's response speed and adjustment capabilities can be further improved, thereby improving the energy conversion efficiency of the gas energy storage system.

[0065] In one embodiment of the present disclosure, updating the second control parameter of the second power supply module based on the first target control parameter to obtain the second target control parameter includes:

[0066] Determining a first ratio, where the first ratio is a ratio between a first control parameter and a corresponding second control parameter;

[0067] 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.

[0068] 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, namely the first ratio. This first ratio can be set based on factors such as the design parameters, performance characteristics, and operating conditions of the two power supply modules, or it can be derived through real-time measurement and calculation. This ratio reflects the correlation or coordination of the control parameters of the two power supply modules, ensuring that they can cooperate with each other during operation to jointly meet the overall system requirements.

[0069] After determining the first ratio, the system updates the second control parameter of the second power supply module based on this ratio and the first target control parameter of the first power supply module. For example, if the exhaust gas flow rate (first control parameter) of the first power supply module is 8 m³ / h, and the corresponding heat recovery medium flow rate (second control parameter) of the second power supply module is 2 m³ / h, the first ratio is 4. If the new exhaust gas flow rate is 12 m³ / h, the heat recovery medium flow rate of the second power supply module is updated to: 12 m³ / h × 1 / 4 = 3 m³ / h.

[0070] As can be seen from the above, 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 parameters of the second power supply module accordingly. This approach not only improves the overall operating efficiency of the system but also ensures coordinated operation between the modules, thereby improving energy conversion efficiency.

[0071] In one embodiment of the present disclosure, updating the second control parameter of the second power supply module based on the first ratio and the first target control parameter includes:

[0072] Calculating a first variation, where the first variation is a variation between the first target control parameter and the first control parameter;

[0073] 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;

[0074] The second control parameter of the second power supply module is updated based on the second change.

[0075] In this embodiment, the first variation is used to measure the degree of change in the control parameters 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 parameters to the first target control parameters), this change will affect the second power supply module. For example, if the power output of the first power supply module is updated from a first power to a second power, where the first power is less than the second power, the magnitude of this 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.

[0076] 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 this relationship (the first ratio). After determining the second change, the system determines an updated second target control parameter based on the second change and the original second control parameter of the second power supply module. This allows the control parameters of the second power supply module to be adjusted accordingly based on the changes in the first power supply module to adapt to the target operation strategy and ensure coordinated operation between the two modules.

[0077] 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.

[0078] In one embodiment of the present disclosure, determining a target operation strategy based on the first load amount and the second load amount includes:

[0079] selecting a target operating strategy from a plurality of operating strategies of the control module based on the first load amount and the second load amount;

[0080] Among them, different operation strategies correspond to different power supply modules.

[0081] In this embodiment, an operating strategy refers to a specific scheme for controlling the operation of the gas energy storage system. Each operating strategy includes a series of parameter settings and control instructions that dictate the operating modes of the first and second power supply modules, such as power output settings, gas flow control, and heat recovery medium flow control. Different operating strategies are suitable for different system requirements and operating conditions. For example, one operating strategy may focus on maximizing power output during peak hours, while another may improve energy conversion efficiency to save energy during low loads.

[0082] The target operating strategy is selected from multiple operating strategies stored in the control module and is used to optimize the current system operation. The target operating strategy is determined based on the first load and the second load, with the goal of achieving the highest energy conversion efficiency for the entire gas energy storage system.

[0083] 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.

[0084] Different operating strategies correspond to different power supply modules. Some operating strategies tend to adjust the control parameters of the first power supply module, some operating strategies tend to adjust the control parameters of the second power supply module, and some operating strategies can adjust multiple control parameters of the first and second power supply modules at the same time. Different operating scenarios and goals require different levels of system control accuracy. For example, a simple operating strategy may only include two parameters: power output and gas flow, while a complex operating strategy, in addition to the above two parameters, also includes the setting of multiple parameters such as combustion temperature, heat recovery medium temperature and flow.

[0085] 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;

[0086] Selecting a target operating strategy from the operating strategies of the control module based on the first load amount and the second load amount includes:

[0087] If the first load is greater than a first preset threshold and the second load is equal to or less than a second preset threshold, determining the target operation strategy to be the first operation strategy;

[0088] 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;

[0089] If the first load is greater than a first preset threshold and the second load is greater than a second preset threshold, the target operation strategy is determined to be the first operation strategy and the second operation strategy.

[0090] In this embodiment, when the first load is greater than a first preset threshold, it indicates that the control parameters of the first power supply module need to be adjusted, thereby improving the first energy conversion efficiency. When the second load is greater than a second preset threshold, it indicates that the control parameters of the second power supply module need to be adjusted, thereby improving the second energy conversion efficiency.

[0091] Because the first operating strategy is the operating strategy for the first power supply module, and the second operating strategy is the operating strategy for the second power supply module. Therefore, if the first load amount is greater than the first preset threshold value, and the second load amount is equal to or less than the second preset threshold value, it can be considered that the first power supply module has an abnormality, 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 amount is greater than the second preset threshold value, and the first load amount is equal to or less than the first preset threshold value, it can be considered that the second power supply module has an abnormality, 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 amount is greater than the first preset threshold value, and the second load amount is greater than the second preset threshold value, it can be considered that the first power supply module and the second power supply module have an abnormality, 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.

[0092] In this embodiment, the first preset threshold value can be determined based on the design specifications of each engine in the gas generator set, the degree of equipment aging, energy costs, and pollution emission standards. The second preset threshold value can be determined based on the heat recovery medium, heat conversion efficiency, heat recovery economic costs, and pollutant emission standards.

[0093] As can be seen from the above, this embodiment can select the optimal target operating strategy from different operating strategies by comparing the relationship between the first and second load amounts and the preset threshold. This selection mechanism not only improves the adaptability and flexibility of the energy conversion system, but also ensures that the system maintains high operating efficiency under different operating conditions.

[0094] 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:

[0095] Extract the target operation strategy to obtain the target features;

[0096] Calculating a matching degree between the target feature and each first control parameter, and determining a third control parameter from the plurality of first control parameters based on an arrangement order of the matching degrees;

[0097] The third control parameter is updated to obtain the first target control parameter.

[0098] The target operation strategy includes the number of parameters;

[0099] Determining a third control parameter from the plurality of first control parameters based on the order of arrangement of the matching degrees includes:

[0100] The first n matching degrees are selected from the order of arrangement of the matching degrees, and a 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.

[0101] In this embodiment, feature extraction is performed on the target operation strategy to obtain target features, including: determining target operation strategy effect words, segmenting the text in the target operation strategy to obtain multiple target words;

[0102] Calculate the relevance of each target word to the target operation strategy effect word;

[0103] Determine target features based on relevance.

[0104] After determining the target characteristic, the degree of match between the target characteristic and each first control parameter needs to be calculated. Based on the matching results, a third control parameter is determined from the multiple first control parameters. The target characteristic is a key indicator extracted from the target operation strategy, such as a specific power output range or gas flow rate. The first control parameters are the various parameters that control the operation of the first power supply module, such as actual output power and combustion temperature. Calculating the degree of match determines the extent to which each first control parameter meets the requirements set by the target characteristic.

[0105] For example, suppose the target characteristic requires the first power supply module to increase its output power to 800 kW within a certain timeframe, and the first control parameter includes a power regulation rate. If the power regulation rate is 50 kW per minute, then a calculation (for example, calculating the time required to reach the target power based on the current power, target power, and regulation rate) can be used to determine the degree of compatibility between this power regulation rate and the target power increase requirement. If the calculation results show that this regulation rate can achieve the target power of 800 kW within a reasonable timeframe, the compatibility is high. Conversely, if the regulation rate is too slow and the target power cannot be reached in a timely manner, the compatibility is low.

[0106] After calculating the degree of match between the target feature and each first control parameter, these matching degrees are arranged in descending order. This order can intuitively demonstrate the degree of fit between each first control parameter and the target feature. The top n matching degrees are then selected from the order of matching degrees, and based on these top n matching degrees, a third control parameter is determined from the multiple first control parameters.

[0107] 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, based on 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.
