Description

Technical Field

[0001] The present invention relates to an intelligent control system, and in particular to a hybrid energy storage working state intelligent control system based on big data. Background Art

[0002] As the proportion of renewable energy continues to increase globally, hybrid energy storage systems, due to their multi-energy complementary characteristics, have become key equipment for smoothing fluctuations and improving grid stability. In existing energy storage systems, the coordinated operation of heterogeneous energy storage units such as gas tanks and batteries faces many challenges. On the one hand, there is a strong coupling relationship between environmental parameters such as temperature, pressure, and humidity and multiple physical fields such as gas flow rate and state of charge. Traditional single-variable PID control methods are prone to parameter oscillation, resulting in a 10% to 25% decrease in system efficiency. On the other hand, fixed threshold management models are difficult to apply in dynamic load scenarios, especially in cases of extreme temperature fluctuations (>2°C / minute) and excessive humidity (>60%). Equipment aging is accelerated, and maintenance costs increase by more than 30%.

[0003] In recent years, data-driven approaches have been introduced to the field of energy storage control, aiming to improve the operational efficiency and stability of energy storage systems by collecting and analyzing large amounts of operational data. However, existing algorithms still have some shortcomings. On the one hand, they often fail to establish a quantitative correlation model between energy storage efficiency, environmental stability, and equipment lifespan. The optimization objective is too simplistic and fails to fully consider the complex relationships between these factors. On the other hand, faced with the problem of multi-constraint coupling, existing intelligent control technologies are prone to falling into local optimality, making it difficult to find the global optimal solution, resulting in limited overall performance.

[0065] The technical solution of the present invention is described in detail below with reference to the accompanying drawings.

[0066] like Figure 1 As shown, the intelligent control system of hybrid energy storage working status based on big data is as follows:

[0067] The temperature monitoring and regulation module is used to monitor the temperature of the energy storage system or its operating environment in real time, make adjustments based on temperature data fed back by the sensor, and automatically control the heating or cooling equipment to keep the energy storage system within the set optimal temperature range. It includes a temperature sensor and a first PID controller. The temperature sensor is used to monitor the temperature of the energy storage system and its operating environment in real time and provide timely feedback. The first PID controller is used to automatically adjust the temperature to ensure that the equipment operates at the optimal temperature state.

[0068] The pressure monitoring and control module is used to monitor pressure changes within the system or working environment in real time, ensuring that the system is always within a safe pressure range. If the module detects a leak in the device, it will immediately trigger an alarm to alert personnel to conduct maintenance. It includes a pressure sensor and a second PID controller. The pressure sensor is responsible for monitoring the pressure in the system in real time, providing accurate pressure data and ensuring that an alarm or notification is triggered when the pressure is abnormal. The second PID is responsible for automatically adjusting and maintaining the pressure to ensure that the energy storage system operates stably within the appropriate pressure range, avoiding damage caused by excessively high or low pressure, and improving the system's safety and performance.

[0069] The humidity monitoring and dehumidification module is used to monitor the humidity level of the energy storage system or working environment to prevent excessive humidity from negatively impacting the energy storage equipment. It includes a humidity sensor and a condenser. The humidity sensor is used to monitor the humidity level of the energy storage system or working environment. The condenser is responsible for cooling the gas and condensing it into liquid through heat exchange, helping to manage thermal energy, control system temperature, and improve overall efficiency.

[0070] The flow rate monitoring and regulation module is responsible for real-time monitoring of the gas flow rate in the energy storage system and optimizing the flow rate through intelligent control methods to ensure efficient, safe, and stable operation of the system. It includes a flow rate sensor and an exhaust fan. The flow rate sensor is used to monitor the flow rate of air, liquid, or gas to ensure the normal flow of air or liquid in the system. The exhaust fan is used to automatically start according to the environment to adjust the flow rate and maintain the efficient operation of the ventilation system.

[0071] The gas storage tank, the temperature monitoring and regulation module, the pressure monitoring and control module, the humidity monitoring and dehumidification module, and the flow rate monitoring and regulation module are respectively connected to the gas storage tank.

[0072] The core operation and multi-parameter collaborative execution module is used to receive data from temperature sensors, pressure sensors, humidity sensors, and flow rate sensors, execute the population iterative calculation of the Golden Jackal algorithm (GJO), and convert the optimization parameters output by the algorithm into control instructions for each module. It is independently deployed in the system main control unit.

[0073] The first PID controller is used to intelligently control the temperature so that the energy storage element operates within a given suitable temperature range. The core idea of the first PID controller is to achieve dynamic adjustment of the system through a weighted combination of the proportional (current error), integral (historical error accumulation), and differential (future error prediction), ultimately stabilizing the temperature near the set value, that is, 15°C-25°C.

[0074] Among them, the output formula of the first PID controller is constructed as follows:

[0075]

[0076] Where u(t) represents the output signal of the controller, K p , K i , K d Represent the proportional gain, integral gain, and differential gain respectively; e(t) represents the error value at the current moment;

[0077] represents the integral of the error accumulated over time, Indicates the instantaneous rate of change of error.

[0078] The second PID controller is used to intelligently control the pressure so that the energy storage element operates within a given appropriate pressure range. The core idea of the second PID controller is to achieve dynamic adjustment of the system through a weighted combination of the proportional (current error), integral (historical error accumulation), and differential (future error prediction), ultimately stabilizing the pressure near the set value, that is, 6-10 bar.

[0079] The second PID controller formula is as follows:

[0080]

[0081] Among them, u p (t) represents the output signal of the controller, Represents proportional gain, integral gain, and differential gain respectively, e p (t) represents the error value at the current moment;

[0082] represents the integral of the error accumulated over time, Indicates the instantaneous rate of change of error.

[0083] The condenser is used to intelligently control humidity so that the energy storage element can operate within a given suitable humidity range. The condenser dehumidification output formula is as follows:

[0084] ΔH=k c ·P c Δt;

[0085] Where ΔH represents the temperature drop, k c represents the condenser power, and Δt represents the operating time. During the process, the operation of the condenser will reduce the gas temperature and needs to cooperate with the temperature regulation module. At this time, the condenser runs at full power, and the temperature regulation module compensates for the temperature drop caused by condensation, ultimately making the working environment humidity lower than 60%;

[0086] The exhaust fan is used to intelligently control the gas flow rate so that the energy storage element can operate within a given suitable gas flow rate range. The output formula of the PID controller is constructed as follows:

[0087]

[0088] Where N(t) represents the real-time speed of the exhaust fan, controls the output, and drives the exhaust fan to adjust the gas flow rate; K pv , e v (t), K iv , respectively represent the proportional coefficient, flow rate deviation, and integral coefficient;

[0089] represents the integral of historical deviations;

[0090] Through the combination of proportional and integral terms, the exhaust fan speed N(t) is dynamically adjusted to make the actual flow rate approach the target value.

[0091] That is 0.5-2m 3 / min;

[0092] Construct a comprehensive optimization objective function J that integrates energy storage efficiency, environmental stability, and life loss:

[0093]

[0094] Where J represents the objective function, λ1, λ2, and λ3 represent the energy storage efficiency weight coefficient, the environmental fluctuation penalty weight coefficient, and the life loss weight coefficient, respectively; η storage represents the energy storage efficiency, They represent temperature variance, pressure variance, humidity variance, and flow rate variance respectively; ΔSOH represents the health state attenuation;

[0107] Where T_Mt, P_Mt, H_Mt, V_Mt, respectively represent the dynamic setting value of the temperature PID controller (instead of the attached Figure 1 fixed 20℃), the optimized set pressure of the pressure control module (instead of fixed 8bar), the humidity threshold for condenser startup (instead of fixed 60%), the target value of the flow rate PI control (instead of fixed 1m 3 / min);

[0116] where K p , K i , K d are the proportional, integral, and differential gains of the first PID controller respectively; T_actual is the actual temperature measurement value;

[0117] 2. Pressure-flow rate coordinated control: coupling relationship modeling

[0122] Where SOC_Mt represents the average state of charge optimized by GJO, ranging from 0.3 to 0.8; a represents the SOC correction coefficient;

[0123] 3. Humidity-temperature compensation logic: dynamic adjustment of condenser power
