Description

TECHNICAL FIELD

[0001] The application belongs to the field of equipment load dynamic management and regulation, and particularly relates to an equipment load dynamic management and regulation method. BACKGROUND

[0002] As the core carrier of marine ecosystem protection and scientific research, the observation platform of the marine nature reserve undertakes key tasks such as water quality monitoring, biodiversity investigation, and meteorological and hydrological data collection. However, such platforms are usually deployed in remote sea areas far from land, and the energy supply is highly dependent on limited renewable energy (such as solar energy, wind energy, and wave energy) and energy storage batteries, facing the prominent contradiction between "unstable energy supply" and "continuous operation demand" of equipment.

[0003] In the prior art, the energy management of the observation platform mostly adopts a "static allocation" mode:

[0004] Low energy utilization efficiency: real-time power of multi-source power generation systems such as solar photovoltaic, vertical axis wind power, and wave energy is not monitored and integrated, resulting in waste in capturing and converting renewable energy;

[0005] Lack of dynamic load regulation: the equipment operation state is fixed, and dynamic adjustment is not made according to the remaining capacity of the energy storage battery, real-time power generation, and equipment load importance, often resulting in problems such as "high-priority equipment stopping due to energy storage depletion" or "low-priority equipment continuously consuming power";

[0006] Single energy-saving strategy: energy saving is achieved through simple "on-off" control, and hierarchical energy-saving strategies are not designed for different equipment characteristics, making it difficult to balance between "reducing energy consumption" and "ensuring data continuity".

[0007] The above problems directly lead to insufficient power supply continuity and stability of the observation platform, seriously restricting the integrity of long-term ecological monitoring data, and even missing important observation opportunities such as rare marine biological activities and extreme weather events due to key equipment downtime. SUMMARY

[0008] The purpose of the present application is to provide an equipment load dynamic management and regulation method, which constructs an energy-saving strategy implementation order table, combines real-time power generation and energy storage state, and dynamically manages the load of the equipment of the marine nature reserve observation platform, so that the equipment sequentially enters "the lowest state" operation, significantly reduces the total load power and power consumption, maximizes the extension of the power supply time, and ensures the continuity and stability of the observation tasks of the marine nature reserve.

[0009] To achieve the above purpose, the technical solution of the present application is: an equipment load dynamic management and regulation method, comprising:

[0010] According to the importance of equipment load and the working characteristics of the marine nature reserve observation value guard platform, an equipment energy saving strategy implementation sequence table is set up;

[0011] Through real-time online detection of photovoltaic, wind power, wave power generation and seawater desalination status, the real-time total power of photovoltaic, wind power and wave power generation is calculated;

[0012] Through online detection of real-time capacity of energy storage battery and real-time power of equipment, it is analyzed and compared whether to execute or exit the energy saving control measures.

[0013] Further, the energy saving control measures include: intelligent sleep standby, dynamic power adjustment, timing on-off, remote start-stop, so that the related equipment of the marine nature reserve observation value guard platform enters the "minimum state" operation mode in sequence.

[0014] Further, the method comprises the following steps:

[0015] S1, according to the historical meteorological data of the relevant sea area, the annual multi-energy complementary power generation comprehensive output curve of the sea area is drawn, the photovoltaic, wind power and wave power generation output in different seasons and months is measured, and the rated power of multi-energy complementary power generation unit and the proportion of each new energy power generation unit power are determined;

[0016] S2, according to the importance of equipment load and the working characteristics of the marine nature reserve observation value guard platform, the "minimum state" operation mode is maintained, including dynamic power adjustment, intelligent sleep standby, preset on-off time, remote start-stop, and the equipment energy saving strategy implementation sequence table is made to implement the energy saving strategy in sequence;

[0017] S3, taking into account the power consumption of various equipment loads maintaining the "minimum state" operation mode, the annual power generation comprehensive output curve of the normal operation mode and the "minimum state" operation mode is drawn, and the energy saving control measure execution and exit conditions are calculated;

[0018] S4, real-time detection and calculation of photovoltaic, wind power, wave power real-time total power, energy storage battery real-time capacity, equipment load total power, when the energy saving control measure execution condition is met, the energy saving control measure process is executed in sequence, and the related equipment "minimum state" operation mode is maintained; when the energy saving control measure implementation condition is not met, the energy saving control measure process is exited in sequence, and the related equipment returns to the "normal operation" state.

[0019] Furthermore, the rated installed capacity of photovoltaic, wind power, and wave energy generator sets is designed based on the actual power load of the marine nature reserve observation and monitoring platform, taking into account factors such as the suction tube jacket foundation structure of the marine nature reserve observation and monitoring platform and its available space, the climate conditions for new energy power generation, the characteristic structure of the generator set, installation conditions, and safe and stable operation. Based on this, the effective area of ​​solar panels and ocean wave energy panels is optimized, and the rated capacity of energy storage batteries is configured.

[0020] Furthermore, the wave energy power generation device automatically switches between two operating modes—wave energy power generation and seawater desalination—based on the real-time capacity of the energy storage battery and the total real-time power generation of wind power, photovoltaic power, and wave energy.

[0021] When the wave energy generation device is in operation, it captures kinetic energy by moving with the waves through the floating body, realizing the three-level conversion of wave energy → mechanical energy → electrical energy, and providing clean marine wave energy power to the observation and monitoring platform of the marine nature reserve nearby.

[0022] In the seawater desalination process, the wave energy generator captures kinetic energy by moving with the waves through a floating body, and then directly drives the seawater desalination device through mechanical energy. This achieves a three-stage conversion from wave energy to mechanical energy to seawater desalination, thus completing the seawater desalination process.

[0023] Furthermore, based on the importance of equipment load and operational characteristics of the marine nature reserve observation and monitoring platform, a sequence table for implementing energy-saving strategies is established, specifically as follows:

[0024] Equipment is divided into uncontrolled equipment and controlled equipment. Equipment that needs to work continuously or intermittently on demand is classified as uncontrolled equipment, while equipment that can be adjusted as needed is classified as controlled equipment.

[0025] Based on the operating characteristics and load importance of the controlled equipment, energy-saving control measures and priorities are set. , The higher the value, the higher the priority; those with higher priority will be given priority in ensuring power supply operation. That is, equipment will implement energy-saving control measures in order of priority from low to high, and equipment will withdraw from energy-saving control measures in order of priority from high to low.

[0026] Furthermore, the rated installed capacities for wind power, photovoltaic, and wave energy generator units are set as follows: , , The system's rated total installed capacity is It is equal to the sum of all rated capacities:

[0027]

[0028] To ensure the continuous and stable operation of the equipment of the marine nature reserve observation and surveillance platform, the rated total installed capacity should be N times the rated total load of the equipment .

[0029]

[0030] Based on the suction pile jacket foundation structure of the marine nature reserve observation and surveillance platform and its available space, new energy power generation climate conditions, generator set characteristics, installation conditions, and factors affecting safe and stable operation, the proportion of the installed capacity of three types of new energy power generation equipment is set as , , .

[0031] Considering the seasonal impact on wind power, photovoltaic power, and wave power generation capacity, the weight coefficients of the power generation capacity are set as , where i takes the value of 1, 2, or 3, representing wind power, photovoltaic power, and wave power, respectively; and j takes the value of 1, 2, 3, or 4, representing spring, summer, autumn, and winter, respectively.

[0036] Further, the rated capacity of the energy storage battery is N times the rated total load of the equipment :

[0037]

[0038] M represents that under extreme climate conditions where wind power, photovoltaic power, and wave power are all not generated, the energy storage battery capacity should ensure continuous operation time of not less than M days according to the importance and continuous operation characteristics of the marine nature reserve observation and surveillance platform.

[0039] The real-time capacity of the energy storage battery is Wh .

[0040]

[0041] SOC is the proportion of the current remaining capacity of the energy storage battery to the rated capacity.

[0042] The real-time total power of the equipment is:

[0043]

[0044] n is the number of devices.

[0045] Further, the lower limit ratio of the power generation capacity that needs to take energy-saving control measures is set: That is, when the following conditions are met, the necessary energy-saving control measures are triggered:

[0046]

[0047] The upper limit ratio of the power generation capacity that needs to take energy-saving control measures is set: That is, when the following conditions are met, the necessary energy-saving control measures are triggered:

[0048]

[0049] is the total real-time power generation of photovoltaic, wind power, and wave power, is the system dynamic power generation capacity.

[0050] Further, by online detection of the real-time capacity of the energy storage battery and the real-time power of the device, it is analyzed and compared to determine whether to execute or exit the energy-saving control measures, which is implemented as follows:

[0051] (1) Real-time detection of the current remaining capacity of the energy storage battery SOC, which reaches the following critical point when switching the charging and discharging state:

[0071] The selected controlled device is added to the regulated device set , the selection is terminated, and the iteration is exited.

[0072] The energy-saving regulation measures are sequentially executed on the controlled devices in the regulated device set .

[0073] When the controlled devices have all executed the energy-saving regulation measures and there is no controlled device that can execute the energy-saving regulation measures, i.e., the system currently has no regulation capacity, the remaining operation duration is calculated, a push alarm information is generated, and the shore-based management and control center executes emergency measures including emergency power generation vehicles to provide emergency power generation according to the pre-plan.

[0094] The technical solutions of the present application will be specifically described below in conjunction with the drawings.

[0095] The present application provides a device load dynamic management and regulation method, comprising:

[0096] According to the device load importance and working characteristics of the marine nature reserve observation value platform, an energy-saving strategy implementation order table is set.

[0097] Through real-time online detection of photovoltaic, wind power, wave power generation and seawater desalination state, the total real-time power generation of photovoltaic, wind power and wave power is calculated;

[0098] Through online detection of real-time capacity of energy storage battery and real-time power of equipment, it is analyzed and compared whether to execute or exit energy-saving control measures.

[0099] The following is the specific implementation process of the present application.

[0100] The device load dynamic management and control method of the present application comprises the following steps:

[0101] As shown in the figure, the device load dynamic management and control method of the present application mainly comprises the following steps: Figure 1

[0102] S1, according to the historical meteorological data of the relevant sea area, the annual multi-energy complementary power generation comprehensive output curve of the sea area is drawn, the photovoltaic, wind power and wave power generation output in different seasons and months is measured and calculated, the rated power of multi-energy complementary power generation unit and the proportion of power of each new energy power generation unit are determined;

[0103] S2, according to the equipment load importance and working characteristics of the marine nature reserve observation and watch platform, the maintenance of "minimum state" running mode including dynamic power adjustment, intelligent sleep standby, preset on-off time, remote start-stop machine is formulated, and the equipment energy-saving strategy implementation sequence table of the energy-saving strategy in sequence is formulated;

[0104] S3, taking into account the power consumption of various equipment loads maintaining "minimum state" running mode, the comparison of annual power generation comprehensive output curve between normal running mode and "minimum state" running mode is drawn, and the execution and exit conditions of energy-saving control measures are calculated;

[0105] ​S4. Real-time detection and calculation of the total real-time power generation of photovoltaic, wind power, and wave energy, the real-time capacity of energy storage battery packs, and the total power load of equipment. When the conditions for implementing energy-saving control measures are met, the energy-saving control measures process is executed in sequence to maintain the relevant equipment in the "minimum state" operating mode. When the conditions for implementing energy-saving control measures are not met, the energy-saving control measures process is exited in sequence, and the relevant equipment is restored to the "normal operation" state.

[0106] In this example, the rated installed capacity of photovoltaic, wind power, and wave energy generator sets is designed based on the actual power load of the marine nature reserve observation and monitoring platform. It takes into account factors such as the suction tube jacket foundation structure of the marine nature reserve observation and monitoring platform and its available space, the climate conditions for new energy power generation, the characteristic structure of the generator sets, installation conditions, and safe and stable operation. Based on this, the effective area of ​​solar panels and ocean wave energy panels is optimized, and the rated capacity of energy storage batteries is configured.

[0107] In this example, the wave energy power generation device automatically switches between two working states: wave energy power generation and seawater desalination, based on the real-time capacity of the energy storage battery and the real-time total power generated by wind power, photovoltaic power, and wave energy.

[0108] When the wave energy generation device is in operation, it captures kinetic energy by moving with the waves through the floating body, realizing the three-level conversion of wave energy → mechanical energy → electrical energy, and providing clean marine wave energy power to the observation and monitoring platform of the marine nature reserve nearby.

[0109] In the seawater desalination process, the wave energy generator captures kinetic energy by moving with the waves through a floating body, and then directly drives the seawater desalination device through mechanical energy. This achieves a three-stage conversion from wave energy to mechanical energy to seawater desalination, thus completing the seawater desalination process.

[0110] In this example, a sequence table for implementing energy-saving strategies is set up based on the importance and operating characteristics of the equipment load. The specific implementation is as follows:

[0111] Equipment is divided into uncontrolled equipment and controlled equipment. Equipment that needs to work continuously or intermittently on demand is classified as uncontrolled equipment, while equipment that can be adjusted as needed is classified as controlled equipment.

[0112] Based on the operating characteristics and load importance of the controlled equipment, energy-saving control measures and priorities are set. , The higher the value, the higher the priority; those with higher priority will be given priority in ensuring power supply operation. That is, equipment will implement energy-saving control measures in order of priority from low to high, and equipment will withdraw from energy-saving control measures in order of priority from high to low.

[0113] Table 1 is the sequence table for implementing the energy-saving strategy of the equipment set in this invention.

[0114] Table 1: Sequence table of implementing equipment energy-saving strategy

[0115]

[0116] In this example, the rated installed capacity of wind power, photovoltaic, and wave energy generator set is respectively set as , , , the rated total installed capacity of the system is , which is equal to the sum of each rated capacity:

[0117]

[0118] To ensure the continuous and stable operation of the marine nature reserve observation and surveillance platform equipment, the rated total installed capacity should be N times of the rated total load of the equipment , usually N is 5:

[0119]

[0120] Combined with the suction pile jacket foundation structure including the marine nature reserve observation and surveillance platform and its available space, new energy power generation climate conditions, generator set characteristic structure, installation conditions, and factors for safe and stable operation, the proportion of the installed capacity of three new energy power generation equipment is set as , , , usually the value is 0.5, 0.2, and 0.3;

[0121] Combined with the seasonal influence on wind power, photovoltaic, and wave energy generation capacity, the generation capacity weight coefficient is set as , i takes the value range of 1, 2, and 3, respectively representing wind power, photovoltaic, and wave energy; j takes the value range of 1, 2, 3, and 4, respectively representing spring, summer, autumn, and winter; Table 2 is the generation capacity weight coefficient table set by the present application.

[0122] Table 2: Seasonal generation capacity coefficient

[0123]

[0124] Combined with the above conditions, the system dynamic generation capacity is:

[0125]

[0126] The real-time online detection of wind power, photovoltaic, and wave real-time generation power is respectively , , , the total real-time generation power of photovoltaic, wind power, and wave energy is calculated as :

[0127] .

[0128] In this example, the rated capacity of the energy storage battery is required in combination with the known conditions The total rated load of the device is N times:

[0129]

[0130] M represents the requirement of the importance and continuous working characteristics of the marine nature reserve observation value guard platform in the extreme climate conditions (windless and calm sea, dark clouds) where wind power, photovoltaic power, and wave power are all unavailable. The energy storage battery capacity should ensure continuous operation time of not less than M days (24M hours);

[0131] The real-time capacity of the energy storage battery is Wh:

[0132]

[0133] SOC is the proportion of the current remaining capacity of the energy storage battery to the rated capacity;

[0134] The real-time total power of the device is :

[0135]

[0136] n is the number of devices.

[0137] In this example, the lower limit ratio of the power generation capacity that needs to take energy-saving control measures is set as That is, when the following conditions are met, the necessary energy-saving control measures are triggered:

[0138]

[0139] The upper limit ratio of the power generation capacity that needs to take energy-saving control measures is set as That is, when the following conditions are met, the necessary energy-saving control measures are triggered:

[0140]

[0141] is the real-time total power of photovoltaic power, wind power, and wave power, is the dynamic power generation capacity of the system.

[0142] In this example, based on the safe and stable operation of the battery of the energy storage system, the upper and lower limits of the battery SOC are set, as shown in Table 3:

[0143] : the minimum value set to prevent over-discharge of the battery;

[0144] : the maximum value set to prevent overcharging of the battery;

[0145] The energy storage system is an important support for the energy saving strategy. To reasonably adjust the power through the energy storage, set the upper and lower limits of the energy storage SOC adjustment as shown in Table 3:

[0146] : the minimum value of triggering power adjustment;

[0147] : the maximum value of triggering power adjustment;

[0148] Table 3: Energy storage battery SOC setting parameters

[0149]

[0150] Therefore, the conditions for energy storage to be available: Further, When there is no need to adjust the power, When the power needs to be adjusted. When the system output is left, the charging of the energy storage battery is given priority.

[0151] In this example, the historical curve of the generated power, the sunshine time and the wind speed of the weather forecast are combined to use the BP neural network algorithm to predict the future ultra-short-term wind power, photovoltaic power and wave energy generation capacity. The predicted curves are respectively: , , The total generation capacity curve is:

[0152] .

[0153] When the generated power significantly decreases, further check the energy storage, predict the ultra-short-term generation capacity, calculate the expected load and adjustable power, and dynamically select the equipment according to the equipment priority from low to high to execute the control measures, so as to reduce the system load;

[0154] When the generated power significantly increases, further check the energy storage, predict the ultra-short-term generation capacity, calculate the expected load and adjustable power, and dynamically select the equipment according to the equipment priority from high to low to exit the control measures;

[0155] In order to ensure that the energy storage system stably supports the system, the remaining power of the energy storage is monitored in real time, and the charging and discharging state is switched if necessary.

[0156] When the short-term generation capacity is detected to be abundant and the energy storage battery has sufficient power, and according to the weather condition prediction, it is possible that there will be power curtailment, the photovoltaic and wind turbine generators continue to supply power to the load at the same time, under the premise of ensuring the safe and stable operation of the observation platform, the wave energy generator set is withdrawn from the power generation state, and automatically switched to the seawater desalination working state, directly using the wave mechanical energy to drive the seawater desalination device (mechanical vapor compression MVC device, etc.), saving the electric energy conversion link, improving the conversion efficiency, and producing fresh water to meet the work and life needs of the duty personnel.

[0157] In this example, as shown in Figure 2 The specific control strategy is implemented as follows

[0158] (1) Real-time detection of the current remaining capacity of the energy storage battery SOC accounts for the rated capacity, and the following critical points are taken when switching the charging and discharging state:
