Description

Technical Field

[0001] The present invention relates to the technical field of marine ranch power supply management, and in particular to a marine ranch power supply management system and method. Background Art

[0002] Marine ranches are a type of farm that conducts regional aquaculture in the ocean. Due to the large scale of aquaculture and the need for a lot of electrical equipment, marine ranches usually need to use wind, photovoltaic, and tidal power generation equipment to generate electricity in order to reduce or directly avoid the use of municipal electricity, thereby optimizing costs.

[0003] The Chinese patent with publication number: CN116452367A discloses an intelligent power supply management system. It includes a balancing area matching module and a balancing time point planning module. The present invention determines the power consumption of different places at different time points through the balancing area matching module, selects the matching area, and plans the balancing time point according to the matching area and the matching time point through the balancing time point planning module. The balancing time point is used as the centralized power supply time point, and the non-essential power supply area is disconnected in time, and the power supply is concentrated to the area with high power consumption, so as to reasonably allocate the power supply at different times and realize intelligent power supply management.

[0004] However, in the existing power supply management of ocean ranches, since electricity is a renewable resource, there is a lack of management constraints on various types of equipment when they are in use, resulting in most equipment being in a high-power working state all year round. This not only causes functions to exceed demand and wastes a large amount of electricity, but also long-term high-power operation will cause equipment to age and damage prematurely. Therefore, the existing ocean ranch power supply system lacks systems and methods for managing such situations.

[0005] In response to the above-mentioned technical defects, a marine ranch power supply management system and method are proposed. The billing rules are set based on the priority weights of power-consuming equipment and the peak and valley levels of renewable electricity resources. The power consumption of equipment is managed by the billing rules to achieve the effect of optimizing power supply management and solve the above-mentioned technical problems. Summary of the invention

[0006] The purpose of the present invention is to provide a marine ranch power supply management system and method, which solves the problem that since electric energy is a renewable resource, there is no constraint when various types of equipment are used, resulting in most equipment being in a high-power working state all year round. This not only causes functions to exceed demand and wastes a lot of electric energy, but also causes premature aging and damage of equipment due to long-term high-power operation.

[0007] To achieve the above object, the present invention provides the following technical solutions:

[0008] A marine ranch power supply management system includes a power storage and power supply system, a peak and valley calculation module, a central management module, a virtual billing module, a primary management module and a secondary management module. The power storage and power supply system is used to store the electric energy of renewable electric resources and transmit it to various marine ranch related equipment. The peak and valley calculation module is used to calculate the peak and valley values ​​of renewable electric resources to realize the prediction function of peak and valley values.

[0009] The central management module is used to process and calculate various data, manage the data in a unified manner, including the peak and valley values ​​of renewable power resources and virtual cost β, and formulate billing rules;

[0010] The virtual billing module implements virtual fee β billing for the ocean ranch-related electrical equipment based on the billing rules of the central management module;

[0011] The primary management module and the secondary management module are used to manage large categories of marine ranch-related electrical equipment and small categories of marine ranch-related electrical equipment, respectively.

[0012] Furthermore, the peak and valley calculation module calculates the peak and valley values ​​of the wind power generation equipment F, the photovoltaic power generation equipment G, and the tidal power generation equipment C in the marine ranch. The specific calculation process is as follows:

[0013] Calculate the wind power generation equipment F. Obtain the air density ρ, the area A swept by the wind turbine blades, the designed maximum wind speed v1, and the wind power generation efficiency η1 through external monitoring equipment or meteorological data. Substitute the above data into the formula of the peak value Ff of the wind power generation equipment F=0.5*ρ*A*v1*η1. Substitute the calculated peak value Ff of the wind power generation equipment F into the formula of the valley value Fg=0.5*ρ*A*v2*η1 of the wind power generation equipment F, where v2 is the minimum wind speed.

[0014] Calculate the photovoltaic power generation equipment G, obtain the equipment parameters to obtain the photovoltaic power generation efficiency η2, the area S of the photovoltaic panel, obtain the data of the maximum light intensity I1 through meteorological data, and substitute the above data into the formula of the peak value Gf=η2*S*I1 of the photovoltaic power generation equipment G, and then substitute it into the valley value Gg=η2*S*I2 of the photovoltaic power generation equipment G, where I2 is the minimum light intensity;

[0015] Calculate the tidal power generation equipment C, obtain the seawater density ρ1, gravity acceleration g, query the local maximum tidal range h1, the maximum flow Q1 tidal power generation equipment efficiency η3, substitute the tidal power generation equipment C peak value Cf=ρ1*g*h1*Q1*η3, substitute the tidal power generation equipment C valley value Cg=ρ1*g*h1*Q2*η3, where Q2 is the minimum flow;

[0016] Calculate the comprehensive peak value Zf=Ff+Gf+Cf, calculate the comprehensive valley value Zg=Fg+Gg+Cg, and obtain the peak period and valley period according to the comprehensive peak value Zf, comprehensive valley value Zg and the current timestamp. The rest of the time is the normal period.

[0017] Furthermore, the central management module also includes a classification unit for classifying the electrical equipment related to the ocean ranch. The classification process is as follows:

[0018] Obtain known marine ranch-related electrical equipment, including monitoring equipment jc, underwater lighting equipment Zm, oxygenation equipment Zy, baiting equipment Tr, and underwater robot charging equipment Jq, and prioritize each type of equipment, with high-level priority given to oxygenation equipment Zy and monitoring equipment jc, medium-level priority given to baiting equipment Tr, and low-level priority given to underwater lighting equipment Zm and underwater robot charging equipment Jq.

[0019] Furthermore, the central management module formulates virtual charging rules based on the calculated peak and valley values ​​of renewable power resources and the classification data of the classification unit. The specific rules are as follows:

[0020] Each type of equipment is divided into high-priority equipment, medium-priority equipment and low-priority equipment. The central management module divides the weight Qz range and discount coefficient Zk according to the equipment priority. The weight Qz range and discount coefficient Zk range of each type of equipment are:

[0021] Advanced priority equipment includes oxygenation equipment Zy and monitoring equipment jc, with a Qz range of 0.5-0.8 and an initial discount factor Zk of 0.1-0.3;

[0022] Intermediate priority equipment includes bait-casting equipment Tr, with a Qz range of 0.8-1.2 and an initial discount factor Zk of 0.3-0.5;

[0023] Low-priority equipment includes underwater lighting equipment Zm and underwater robot charging equipment Jq, with a Qz range of 1.2-1.5 and an initial discount factor Zk of 0.5-0.7;

[0024] Then, based on the corresponding weights Qz and discount coefficients Zk of various types of equipment, the central management module obtains the working status data of various types of equipment and establishes a supervision platform for adjusting the weights Qz and discount coefficients Zk.

[0025] Furthermore, the central management module establishes a supervision platform for evaluating the completion degree Wd of each type of equipment work, and determines the urgency Hd of the next work of each type of equipment based on the completion degree Wd. The specific process is as follows:

[0026] Real-time collection of working status data of various equipment, including: oxygen output of oxygen enrichment equipment Zy, data collection frequency of monitoring equipment jc, bait feeding amount of bait feeding equipment Tr, light intensity of underwater lighting equipment Zm, charging progress of underwater robot charging equipment Jq, and all data are recorded with the timestamp of the equipment at the same time to distinguish between peak, flat and valley periods;

[0027] The completion degree Wd is evaluated. The evaluation method is as follows: based on the monitoring status data, the evaluation index is calculated. The oxygen completion degree Wd of the oxygen enrichment equipment Zy = (actual output oxygen volume / preset standard oxygen volume) × 100%;

[0028] The data collection frequency completion degree of monitoring equipment jc Wd = (actual data collection frequency / preset standard frequency) × 100%;

[0029] The completion degree of feeding amount of feeding equipment Tr Wd = (actual feeding amount / preset feeding amount) × 100%;

[0030] The illumination intensity completion degree Wd of underwater lighting equipment Zm = (actual illumination intensity / preset standard illumination intensity) × 100%;

[0031] The charging progress completion degree Wd of the underwater robot charging equipment Jq = (actual charging progress / preset charging target) × 100%;

[0032] Based on the above calculation results as evaluation indicators, the support vector machine SVM algorithm is used to establish an evaluation model. Based on the completion degree Wd evaluation results, the urgency Hd of the equipment's next work is determined by arranging the completion degree Wd evaluation results from large to small. The urgency Hd is divided into three levels: Class A, Class B, and Class C, corresponding to the completion degree Hd of 0-40%, 40-80%, and 80-n%, respectively, where n>80.

[0033] Furthermore, the central management module adjusts the equipment billing weight Qz and discount coefficient Zk within a range based on the equipment urgency Hd and equipment priority. Under the same urgency Hd, the higher the equipment priority, the higher the adjustment priority, following the principle of relatively low billing for higher priority.

[0034] Furthermore, the virtual billing module implements virtual fee β billing for the ocean ranch-related electrical equipment based on the billing rules of the central management module. The billing formula is as follows:

[0035] Implement time-based virtual billing rules, which are divided into peak time, valley time and normal time. Calculate the virtual fee β that each type of equipment needs to pay during peak time, valley time and normal time. The calculation formula is as follows;

[0036] β peak = comprehensive peak power consumption * [peak power ratio of power generation equipment * equipment billing weight Qz * basic unit price 1 * (1-Zk peak)];

[0037] β flat = comprehensive normal period electricity consumption * [power proportion of power generation equipment during peak period * equipment billing weight Qz * basic unit price 1 * (1-Zk flat)];

[0038] β Valley = comprehensive valley period electricity consumption * [power proportion of power generation equipment during peak period * equipment billing weight Qz * basic unit price 1 * (1-Zk Valley)];

[0039] Among them, the power consumption is monitored by the billing module, and the power proportion of the power generation equipment = the output power of the equipment in a specific period / the total output power;

[0040] Total virtual cost βtotal=βpeak+βflat+βvalley.

[0041] Furthermore, the first-level management module sets a threshold value for the total virtual cost β of monitoring equipment jc, underwater lighting equipment Zm, oxygenation equipment Zy, bait feeding equipment Tr, and underwater robot charging equipment Jq. At the same time, the first-level management module obtains the total virtual cost β of the major equipment in real time and calculates it with the cost threshold. The calculation method is difference Cz=threshold of total virtual cost β-total virtual cost β. When the difference Cz>0, it means that the total virtual cost β has not exceeded the threshold. When the difference Cz<0, it means that the total virtual cost β has exceeded the threshold. The calculation result is transmitted by the central management module to the terminals of various equipment management departments.

[0042] Furthermore, the secondary management module is used to subdivide each device of each category, and the primary management module sets a threshold value of the total virtual cost βtotal for each device of each category. At the same time, the total virtual cost βtotal of each device is calculated through total virtual cost βtotal = βpeak + βflat + βvalley. The calculation method of difference Cz = threshold value of total virtual cost βtotal - total virtual cost βtotal is still used to finally obtain the usage cost of each device of each category of equipment, and manage it in a targeted manner. The equipment working power and time are adjusted according to the cost situation combined with the equipment priority and urgency Hd.

[0043] A method for managing power supply of an ocean ranch, the method specifically comprising the following steps:

[0044] S1: Based on the power storage and power supply system of the ocean ranch, the renewable electricity resources of wind power generation equipment, photovoltaic power generation equipment, and tidal power generation equipment are stored and transmitted to the relevant power consumption equipment of the ocean ranch. The peak and valley calculation module calculates the comprehensive power generation peak value Zf and valley value Zg of the renewable electricity resources to obtain the peak period and valley period, and the rest of the time is the normal period;

[0045] S2: The central management module prioritizes various types of equipment, among which high-level priority includes oxygenation equipment Zy and monitoring equipment jc, medium-level priority includes bait-feeding equipment Tr, and low-level priority includes underwater lighting equipment Zm and underwater robot charging equipment Jq;

[0046] S3: Based on the peak hours, valley hours, normal hours and priorities of various types of equipment obtained in S1 and S2, virtual billing rules are formulated, and two floating coefficients, weight Qz range and discount coefficient Zk, are obtained;

[0047] S4: Collect data on the working status of various equipment in real time, evaluate the degree of completion Wd, and derive the degree of urgency Hd based on the degree of completion Wd;

[0048] S5: Based on the urgency Hd and equipment priority obtained in S4 and S2, adjust the weight Qz and discount factor Zk in S3 within the range;

[0049] S6: Substitute the weight Qz and discount coefficient Zk obtained in S5 into the billing formula to calculate the total virtual cost of small and medium-sized equipment in a large category. Add the total virtual costs of all equipment in this category to get the total virtual cost of this category of equipment βtotal;

[0050] S7: Substitute the β total of a single device and each type of device into the calculation formula of difference Cz=threshold of total virtual cost β total-total virtual cost β total, obtain the difference between the virtual cost β total of each type of device and the virtual cost threshold of each type of device, and the difference between the virtual cost β total of each device and the virtual cost threshold of each device, and transmit the calculation results to the terminals of various types of equipment management departments;

[0051] S8: By calculating the cost difference, reasonably adjust the working power and time of the electrical equipment. The specific adjustment method is as follows: when the difference Cz>0, it means that the total virtual cost βtotal does not exceed the threshold. At this time, maintain the current working status of the equipment, or improve the equipment's working efficiency while ensuring basic operating needs. When the difference Cz<0, it means that the total virtual cost βtotal has exceeded the threshold. At this time, emergency control measures are required. For high-priority equipment, maintain its basic functions. At the same time, reduce the working power of the high-priority equipment or shorten the working time to reduce energy consumption.

[0052] Compared with the prior art, the present invention has the following beneficial effects:

[0053] 1. Through virtual billing, according to the priority and actual power demand of different equipment in the ocean ranch, according to the formulated billing rules, the use of electrical equipment is made more scientific and reasonable, avoiding unnecessary energy waste and achieving optimal management of electricity;

[0054] 2. Collect the working status data of various equipment in real time, combine the completion degree Wd to evaluate the urgency Hd, and adjust the billing weight Qz and discount coefficient Zk according to the urgency Hd and equipment priority. This dynamic billing adjustment mechanism can prompt the equipment department to pay more attention to the operating efficiency and energy consumption of the equipment, thereby actively optimizing the use of equipment and further improving the level of power management;

[0055] 3. Dynamically adjust the weight Qz and discount coefficient Zk in the peak, valley and normal periods in the virtual billing rules, so that the power generation characteristics of renewable energy in different periods can be fully utilized. The management department can reduce the use of virtual fees β in this way, so as to achieve the peak utilization of energy and reduce overall energy consumption;

[0056] 4. Give a lower billing weight and a higher discount coefficient to high-priority equipment, so that key equipment can pay more attention to energy conservation while ensuring operation. At the same time, appropriately increase the billing weight of low-priority equipment, guide the management department to reasonably control the use time and power of such equipment, reduce unnecessary energy consumption, and achieve the goal of overall energy conservation;

[0057] 5. The virtual billing method prompts the management departments of marine ranches to pay more attention to the efficiency of energy utilization and adjust the working power and time of equipment to adapt to changes in billing rules, thereby achieving efficient use of energy, helping to reduce the marine ranch’s dependence on traditional energy, reduce energy costs, and reduce the impact on the environment. This provides strong support for the sustainable development of marine ranches and is in line with the current concept of green development. BRIEF DESCRIPTION OF THE DRAWINGS

[0058] Figure 1 This is a system block diagram of Embodiment 1 of the present invention. DETAILED DESCRIPTION

[0059] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0060] Embodiment 1:

[0061] like Figure 1As shown, the ocean ranch power supply management system of the present invention includes a power storage and power supply system, a peak and valley calculation module, a central management module, a virtual billing module, a primary management module and a secondary management module. The power storage and power supply system is used to store the electric energy of the renewable electric resources and transmit it to various ocean ranch related equipment. The peak and valley calculation module is used to calculate the peak and valley values ​​of the renewable electric resources to realize the prediction function of the peak and valley values;

[0062] The central management module is used to process and calculate various data, manage the data in a unified manner, including the peak and valley values ​​of renewable power resources, virtual cost β, and formulate billing rules;

[0063] The virtual billing module implements virtual fee β billing for ocean ranch-related electrical equipment based on the billing rules of the central management module;

[0064] The primary management module and the secondary management module are used to manage large categories of marine ranch-related electrical equipment and small categories of marine ranch-related electrical equipment, respectively.

[0065] In this embodiment, the peak and valley calculation module calculates the peak and valley values ​​of the wind power generation equipment F, the photovoltaic power generation equipment G, and the tidal power generation equipment C in the marine ranch. The specific calculation process is as follows:

[0066] Calculate the F of wind power generation equipment. Obtain the air density ρ, the area A swept by the wind turbine blades, the designed maximum wind speed v1, and the wind power generation efficiency η1 through external monitoring equipment or meteorological data. Substitute the above data into the formula of the peak value Ff of the wind power generation equipment F=0.5*ρ*A*v1*η1, calculate the peak value Ff of the wind power generation equipment F, and substitute it into the formula of the valley value Fg of the wind power generation equipment F=0.5*ρ*A*v2*η1, where v2 is the minimum wind speed;

[0067] Calculate the photovoltaic power generation equipment G, obtain the equipment parameters to obtain the photovoltaic power generation efficiency η2, the area S of the photovoltaic panel, obtain the data of the maximum light intensity I1 through meteorological data, and substitute the above data into the formula of the peak value Gf=η2*S*I1 of the photovoltaic power generation equipment G, and then substitute it into the valley value Gg=η2*S*I2 of the photovoltaic power generation equipment G, where I2 is the minimum light intensity;

[0068] Calculate the tidal power generation equipment C, obtain the seawater density ρ1, gravity acceleration g, query the local maximum tidal range h1, the maximum flow Q1 tidal power generation equipment efficiency η3, substitute the tidal power generation equipment C peak value Cf=ρ1*g*h1*Q1*η3, substitute the tidal power generation equipment C valley value Cg=ρ1*g*h1*Q2*η3, where Q2 is the minimum flow;

[0069] Calculate the comprehensive peak value Zf=Ff+Gf+Cf, calculate the comprehensive valley value Zg=Fg+Gg+Cg, and obtain the peak period and valley period according to the comprehensive peak value Zf, comprehensive valley value Zg and the current timestamp. The rest of the time is the normal period.

[0070] It should be noted that the calculation of the comprehensive peak value Zf and the comprehensive valley value Zg can comprehensively reflect the overall supply capacity of renewable energy in the marine ranch. According to the comprehensive peak value Zf, the comprehensive valley value Zg and the current timestamp, the time can be divided into peak period, valley period and normal period, which is convenient for reasonably arranging the operation of electrical equipment according to peak, valley and normal times.

[0071] In this embodiment, the central management module further includes a classification unit for classifying the electrical equipment related to the ocean ranch. The classification process is as follows:

[0072] Obtain known marine ranch-related electrical equipment, including monitoring equipment jc, underwater lighting equipment Zm, oxygenation equipment Zy, baiting equipment Tr, and underwater robot charging equipment Jq, and prioritize each type of equipment, with high-level priority given to oxygenation equipment Zy and monitoring equipment jc, medium-level priority given to baiting equipment Tr, and low-level priority given to underwater lighting equipment Zm and underwater robot charging equipment Jq.

[0073] It should be noted that monitoring equipment is used to monitor the water quality, water temperature, and growth of marine organisms in real time in marine ranches, providing data support for scientific management. For example, water quality monitors can detect parameters such as dissolved oxygen, pH, and salinity in water to ensure a suitable growth environment for marine organisms.

[0074] Underwater lighting equipment Zm is used to provide lighting for the underwater area of ​​the marine ranch. On the one hand, it is convenient for the staff to conduct underwater observation and operations. On the other hand, it can also provide a certain lighting environment for marine organisms and promote the growth and reproduction of certain marine organisms.

[0075] Oxygen-enhancing equipment Zy is used to increase the dissolved oxygen content in the water to prevent marine life from dying due to lack of oxygen. Oxygen-enhancing equipment is particularly important in areas with high aquaculture density.

[0076] Feeding equipment Tr is used to feed the organisms in the marine ranch at a regular and quantitative time to ensure the nutrients required for the growth and development of the organisms;

[0077] Underwater robot charging equipment Jq is used to provide charging services for underwater robots. Underwater robots can be used for underwater inspections, equipment maintenance, etc. The charging equipment ensures their continuous operation;

[0078] Oxygenation equipment Zy and monitoring equipment jc are classified as high priority, mainly because they are crucial to the ecological environment and biological safety of marine ranches. Oxygenation equipment is directly related to the survival of marine organisms, while monitoring equipment can detect problems in time and take measures to avoid potential risks;

[0079] Feeding equipment Tr is classified as medium priority because feeding has an important impact on the growth and aquaculture benefits of marine organisms, but its urgency is slightly lower than that of oxygenation and monitoring equipment;

[0080] Underwater lighting equipment Zm and underwater robot charging equipment Jq are classified as low priority, mainly because they are relatively unimportant in the operation of the marine ranch. Underwater lighting equipment is mainly used to assist operations and biological growth, and growth is usually used at night, while underwater robot charging equipment is to ensure the operation of underwater robots.

[0081] In this embodiment, the central management module formulates virtual billing rules based on the calculated peak and valley values ​​of renewable power resources and the classification data of the classification unit. The specific rules are as follows:

[0082] Each type of equipment is divided into high-priority equipment, medium-priority equipment and low-priority equipment. The central management module divides the weight Qz range and discount coefficient Zk according to the equipment priority. The weight Qz range and discount coefficient Zk range of each type of equipment are:

[0083] Advanced priority equipment includes oxygenation equipment Zy and monitoring equipment jc, with a Qz range of 0.5-0.8 and an initial discount factor Zk of 0.1-0.3;

[0084] Intermediate priority equipment includes bait-casting equipment Tr, with a Qz range of 0.8-1.2 and an initial discount factor Zk of 0.3-0.5;

[0085] Low-priority equipment includes underwater lighting equipment Zm and underwater robot charging equipment Jq, with a Qz range of 1.2-1.5 and an initial discount factor Zk of 0.5-0.7;

[0086] Then, based on the corresponding weights Qz and discount coefficients Zk of various types of equipment, the central management module obtains the working status data of various types of equipment and establishes a supervision platform for adjusting the weights Qz and discount coefficients Zk.

[0087] It should be noted that the priority, weight range Qz, and discount coefficient Kz of various types of equipment are shown in Table 1:

[0088] Table 1 Equipment priority corresponding weight and discount coefficient table

[0089]

[0090] In this embodiment, the central management module establishes a supervision platform for evaluating the completion degree Wd of each type of equipment work, and determines the urgency Hd of the next work of each type of equipment based on the completion degree Wd. The specific process is as follows:

[0091] Real-time collection of working status data of various equipment, including: oxygen output of oxygen enrichment equipment Zy, data collection frequency of monitoring equipment jc, bait feeding amount of bait feeding equipment Tr, light intensity of underwater lighting equipment Zm, charging progress of underwater robot charging equipment Jq, and all data are recorded with the timestamp of the equipment at the same time to distinguish between peak, flat and valley periods;

[0092] The completion degree Wd is evaluated. The evaluation method is as follows: based on the monitoring status data, the evaluation index is calculated. The oxygen completion degree Wd of the oxygen enrichment equipment Zy = (actual output oxygen volume / preset standard oxygen volume) × 100%;

[0093] The data collection frequency completion degree of monitoring equipment jc Wd = (actual data collection frequency / preset standard frequency) × 100%;

[0094] The completion degree of feeding amount of feeding equipment Tr Wd = (actual feeding amount / preset feeding amount) × 100%;

[0095] The illumination intensity completion degree Wd of underwater lighting equipment Zm = (actual illumination intensity / preset standard illumination intensity) × 100%;

[0096] The charging progress completion degree Wd of the underwater robot charging equipment Jq = (actual charging progress / preset charging target) × 100%;

[0097] Based on the above calculation results as evaluation indicators, the support vector machine SVM algorithm is used to establish an evaluation model. Based on the completion degree Wd evaluation results, the urgency Hd of the equipment's next work is determined by arranging the completion degree Wd evaluation results from large to small. The urgency Hd is divided into three levels: Class A, Class B, and Class C, corresponding to the completion degree Hd of 0-40%, 40-80%, and 80-n%, respectively, where n>80.

[0098] It should be noted that through the indicators of completion degree Wd and urgency degree Hd, these evaluation indicators can quantify the working status of the equipment, so that managers can intuitively understand the working progress and effect of the equipment, thereby realizing the refined regulation of the power supply management of the marine ranch. The urgency degree Hd corresponds to the completion degree Wd as shown in Table 2:

[0099] Table 2 Completion and urgency correspondence table

[0100]

[0101] In this embodiment, the central management module adjusts the equipment billing weight Qz and discount coefficient Zk within a range based on the equipment urgency Hd and equipment priority. Under the same urgency Hd, the higher the equipment priority, the higher the adjustment priority, following the principle of relatively low billing for higher priority.

[0102] The virtual billing module implements virtual fee β billing for ocean ranch-related electrical equipment based on the billing rules of the central management module. The billing formula is as follows:

[0103] Implement time-based virtual billing rules, which are divided into peak time, valley time and normal time. Calculate the virtual fee β that each type of equipment needs to pay during peak time, valley time and normal time. The calculation formula is as follows;

[0104] β peak = comprehensive peak power consumption * [peak power ratio of power generation equipment * equipment billing weight Qz * basic unit price 1 * (1-Zk peak)];

[0105] β flat = comprehensive normal period electricity consumption * [power proportion of power generation equipment during peak period * equipment billing weight Qz * basic unit price 1 * (1-Zk flat)];

[0106] β Valley = comprehensive valley period electricity consumption * [power proportion of power generation equipment during peak period * equipment billing weight Qz * basic unit price 1 * (1-Zk Valley)];

[0107] Among them, the power consumption is monitored by the billing module, and the power proportion of the power generation equipment = the output power of the equipment in a specific period / the total output power;

[0108] Total virtual cost βtotal=βpeak+βflat+βvalley.

[0109] It should be noted that the urgency of the equipment Hd reflects the urgency of its current working status. For example, equipment with urgency Hd of Class A may be in an emergency state and needs to complete the task as soon as possible to ensure the normal operation of the marine ranch. In this case, the central management module adjusts the billing weight Qz and discount coefficient Kz according to the urgency Hd of the equipment to urge it to be put into operation as soon as possible. For non-urgent equipment, the billing weight Qz is increased and the discount coefficient Kz is reduced to balance energy distribution. The equipment priority reflects the importance of the equipment in the operation of the marine ranch. High-priority equipment such as oxygenation equipment Zy and monitoring equipment jc are directly related to the survival of marine organisms and the safety of the ranch. Therefore, under the same urgency Hd, the billing weight Qz and discount coefficient Kz should be adjusted first to ensure the normal operation of these key equipment. Following the principle of high priority and relatively low billing, the core functions of the marine ranch can be protected from excessive impact of energy costs. For example, when the power generation of renewable electricity resources is low and the energy supply is tight, the power demand of high-priority equipment is prioritized, and its billing weight is reduced and the discount coefficient is increased to enable it to continue to operate under limited energy resources.

[0110] In this embodiment, the first-level management module sets the threshold value of the total virtual cost βtotal for monitoring equipment jc, underwater lighting equipment Zm, oxygenation equipment Zy, bait throwing equipment Tr, and underwater robot charging equipment Jq. At the same time, the first-level management module obtains the total virtual cost βtotal of the major equipment in real time and calculates it with the cost threshold. The calculation method is difference Cz=threshold of total virtual cost βtotal-total virtual cost βtotal. When the difference Cz>0, it means that the total virtual cost βtotal has not exceeded the threshold. When the difference Cz<0, it means that the total virtual cost βtotal has exceeded the threshold. The calculation result is transmitted by the central management module to the terminals of various equipment management departments.

[0111] It should be noted that by implementing time-sharing virtual billing rules for peak periods, valley periods, and normal periods, the management department reasonably plans the use of equipment based on the threshold virtual cost β of the managed equipment type and the virtual cost β that has been incurred, as well as the billing weights Qz and discount coefficients Kz of different types of equipment in different time periods. This can better adapt to changes in the energy supply and electricity demand of the marine ranch and achieve optimal energy allocation.

[0112] In this embodiment, the secondary management module is used to subdivide each device of each category, and the primary management module sets a threshold value of the total virtual cost βtotal for each device of each category.

[0114] Embodiment 2:

[0115] The marine ranch power supply management method of the present invention specifically comprises the following steps:

[0116] S1: Based on the power storage and power supply system of the ocean ranch, the renewable electricity resources of wind power generation equipment, photovoltaic power generation equipment, and tidal power generation equipment are stored and transmitted to the relevant power consumption equipment of the ocean ranch. The peak and valley calculation module calculates the comprehensive power generation peak value Zf and valley value Zg of the renewable electricity resources to obtain the peak period and valley period, and the rest of the time is the normal period;

[0117] S2: The central management module prioritizes various types of equipment, among which high-level priority includes oxygenation equipment Zy and monitoring equipment jc, medium-level priority includes bait-feeding equipment Tr, and low-level priority includes underwater lighting equipment Zm and underwater robot charging equipment Jq;

[0118] S3: Based on the peak hours, valley hours, normal hours and priorities of various types of equipment obtained in S1 and S2, virtual billing rules are formulated, and two floating coefficients, weight Qz range and discount coefficient Zk, are obtained;

[0119] S4: Collect data on the working status of various equipment in real time, evaluate the degree of completion Wd, and derive the degree of urgency Hd based on the degree of completion Wd;

[0120] S5: Based on the urgency Hd and equipment priority obtained in S4 and S2, adjust the weight Qz and discount factor Zk in S3 within the range;

[0121] S6: Substitute the weight Qz and discount coefficient Zk obtained in S5 into the billing formula to calculate the total virtual cost of small and medium-sized equipment in a large category. Add the total virtual costs of all equipment in this category to get the total virtual cost of this category of equipment βtotal;

[0122] S7: Substitute the β total of a single device and each type of device into the calculation formula of difference Cz=threshold of total virtual cost β total-total virtual cost β total, obtain the difference between the virtual cost β total of each type of device and the virtual cost threshold of each type of device, and the difference between the virtual cost β total of each device and the virtual cost threshold of each device, and transmit the calculation results to the terminals of various types of equipment management departments;

[0123] S8: By calculating the cost difference, reasonably adjust the working power and time of the electrical equipment. The specific adjustment method is as follows: When the difference Cz>0, it means that the total virtual cost β does not exceed the threshold. At this time, maintain the current working state of the equipment, or improve the working efficiency of the equipment under the premise of ensuring basic operating needs. For oxygenation equipment Zy and monitoring equipment jc, slightly increase their working power or extend their working time without exceeding the safe operating range of the equipment to better protect the ecological environment and safety monitoring of the marine ranch. For the intermediate priority feeding equipment Tr, the feeding amount and feeding time can be appropriately adjusted according to the growth needs of marine organisms and feed reserves to improve the breeding efficiency. For the low-priority underwater lighting equipment Zm and underwater robot charging equipment Jq, the lighting intensity can be appropriately reduced or the charging time can be adjusted without affecting the underwater operation and the normal operation of the equipment to save energy;

[0124] When the difference Cz<0, it means that the total virtual cost β has exceeded the threshold. At this time, emergency control measures need to be taken. For high-priority equipment, maintain its basic functions, reduce the working power or shorten the working time of high-priority equipment, reduce energy consumption, and reduce the oxygen output of oxygenation equipment, but ensure the survival needs of marine life; reduce the data collection frequency of monitoring equipment, but ensure the monitoring of key data. Secondly, for medium-priority equipment, strictly control its working intensity and time, reduce the amount and number of baiting equipment, and avoid waste and environmental pollution caused by excessive baiting. For low-priority equipment, you can suspend or reduce its use, such as turning off some underwater lighting equipment, or adjusting the charging plan of underwater robots, giving priority to the power demand of important equipment;

[0125] Regardless of whether the difference Cz<0 or Cz>0, you can use various types of equipment reasonably during peak, valley and normal periods based on the preferential conditions of the billing rules and the equipment priority, including but not limited to increasing or decreasing the working power, increasing or decreasing the working hours, suspending the equipment operation or increasing or decreasing the equipment quantity.
