Description

Technical Field

[0001] This invention relates to the field of smart grid technology, and more specifically, to a method and system for predicting the adjustable potential of industrial electricity load. Background Technology

[0002] Currently, a user's physical adjustment potential is the theoretical maximum response potential under a given demand response strategy, also known as the user's "reducibility." A user's adjustable potential, on the other hand, is the final response potential a user can achieve after considering the influence of subjective and objective conditions such as electricity price, incentive mechanisms, the presence or absence of terminal control equipment, communication channel type, terminal control equipment type, communication reliability, and user willingness. In urban areas, diverse users mainly consist of commercial and residential users, with a small number of industrial users. Compared to residential users, implementing demand response for industrial users is more difficult. Industrial processes must consider not only power resources but also material storage, product characteristics, and production shifts. Although industrial loads have high requirements for power supply reliability, some production processes are interruptible. Developing reasonable interruptible load pricing based on the user's interruptible load potential and related costs can guide users to interrupt power consumption during peak daily periods, reducing the pressure on the system's power supply.

[0003] However, there is currently no method in the technology to accurately predict the adjustability potential of industrial users. Summary of the Invention

[0004] The main objective of this invention is to provide a method and system for predicting the adjustable potential of industrial power load, so as to solve the problem that the existing technology cannot predict the adjustable potential of industrial users.

[0005] To achieve the above objectives, according to one aspect of the present invention, a method for predicting the adjustable potential of industrial power load is provided, comprising: step S1: classifying industrial power consumption and obtaining the process flow of each type of industrial power consumption, and determining the response type of the electrical equipment in each process step of the process flow; step S2: determining whether the electrical equipment is a flexible electrical load based on the response type of the electrical equipment in each process step; if the electrical equipment is a flexible electrical load, obtaining the proportion of the flexible electrical load in the total power consumption of the process flow and its response capacity; step S3: obtaining the adjustable potential of this type of industrial power consumption based on the proportion of the flexible electrical load and the response capacity; wherein, the response type includes non-adjustable load, transferable load, and interruptible load; the response capacity is the proportion of the responsive power of all flexible electrical loads in the current process step to the total power of all electrical equipment within multiple set time periods.

[0006] Furthermore, methods for classifying industrial electricity consumption include: dividing industrial electricity consumption into electricity consumption in the steel industry, non-ferrous metals and rolling processing industry, cement industry, chemical fiber industry, papermaking industry, plastics industry, rubber industry, textile industry, chemical industry, electronic component manufacturing industry, electrical appliance manufacturing industry, and daily necessities manufacturing industry.

[0007] Furthermore, determining whether an electrical device is a flexible electrical load based on its response type includes: if the electrical device is an interruptible load, then the electrical device is determined to be a flexible electrical load; if the electrical device is a transferable load, then the electrical device is determined to be a flexible electrical load within a preset time period or at a preset time point.

[0008] Furthermore, the method for predicting the adjustable potential of industrial power load also includes: if the power equipment is determined to be a flexible power load, then the response time of the power equipment is obtained, and the power supply to the power equipment is stopped or the power supply time is adjusted according to the response time; wherein, the response time includes the day-ahead response and the intraday response.

[0009] Furthermore, the method for obtaining the adjustable potential of this type of industrial electricity consumption based on the electricity consumption ratio and response capacity includes: within the current response time, the adjustable potential of this type of industrial electricity consumption is the sum of the products of the electricity consumption ratio and response capacity of each process stage.

[0010] Furthermore, the method for predicting the adjustable potential of industrial electricity load also includes a step S4 following step S3, which is: determining the incentive compensation electricity price based on the adjustable potential.

[0011] Furthermore, the method for determining the response type of electrical equipment in each process step of the process flow includes: listing the electrical equipment used in each process step and determining the response type of each piece of electrical equipment one by one.

[0012] Furthermore, for electrical equipment with a response time of one day in advance, the interruption duration and / or interruption time of the electrical equipment need to be determined at least one working day in advance.

[0013] Furthermore, the response capacity for electricity consumption in the steel industry is 1.

[0014] According to another aspect of the present invention, an industrial power load adjustable potential prediction system is provided, which applies the above-described industrial power load adjustable potential prediction method.

[0015] The industrial power load adjustable potential prediction method, applying the technical solution of this invention, includes the following steps: Step S1: Classifying industrial power consumption and obtaining the process flow of each type of industrial power consumption, and determining the response type of the electrical equipment in each process step; Step S2: Determining whether the electrical equipment is a flexible load based on the response type of the electrical equipment in each process step. If the electrical equipment is a flexible load, then obtaining the proportion of flexible load in the total power consumption of the process and its response capacity; Step S3: Obtaining the adjustable potential of this type of industrial power consumption based on the proportion of flexible load and its response capacity. Thus, the industrial power load adjustable potential prediction method can accurately obtain the adjustable potential of each industry as a prediction reference by analyzing the process flow of industrial users in different industries, collecting the load proportion of each step in the process flow, and simultaneously analyzing the response type and response capacity. This solves the problem in the prior art that the adjustable potential of industrial users cannot be predicted. Furthermore, the industrial power load adjustable potential prediction method in this application has a clear concept, simple method, and accurate prediction results. Attached Figure Description

[0021] To address the problem that existing technologies cannot predict the adjustability potential of industrial users, this application provides a method and system for predicting the adjustability potential of industrial power load.

[0022] like Figure 1 As shown, the methods for predicting the adjustable potential of industrial electricity load include:

[0023] Step S1: Classify industrial electricity consumption, obtain the process flow of each type of industrial electricity consumption, and determine the response type of the electrical equipment in each process step of the process flow.

[0024] Step S2: Determine whether the electrical equipment is a flexible electrical load based on the response type of the electrical equipment in each process step. If the electrical equipment is a flexible electrical load, obtain the proportion of the flexible electrical load in the total power consumption of the process and the response capacity.

[0025] Step S3: Obtain the adjustable potential of this type of industrial power consumption based on the power consumption ratio and response capacity;

[0026] The response types include non-adjustable loads, transferable loads, and interruptible loads; the response capacity is the proportion of the responsive power of all flexible electrical loads under the current process stage to the total power of all electrical equipment within multiple set time periods.

[0027] By applying the technical solution of this embodiment, the method for predicting the adjustable potential of industrial electricity load can accurately obtain the adjustable potential of each industry as a reference for prediction by analyzing the process flow of industrial users in different industries, collecting the load ratio of each link in the process flow, and analyzing the response type and response capacity. This solves the problem that the existing technology cannot predict the adjustable potential of industrial users. Furthermore, the method for predicting the adjustable potential of industrial electricity load in this application has a clear concept, is simple, and provides accurate prediction results.

[0028] In this embodiment, the method for classifying industrial electricity consumption includes:

[0029] Industrial electricity consumption is categorized into electricity consumption for the steel industry, non-ferrous metals and rolling processing industry, cement industry, chemical fiber industry, papermaking industry, plastics industry, rubber industry, textile industry, chemical industry, electronic component manufacturing industry, electrical appliance manufacturing industry, and daily necessities manufacturing industry.

[0030] Specifically, electricity loads are generally categorized into three main types: industrial loads, public utility loads, and residential loads. Industrial loads can be further divided into heavy industrial loads and light industrial loads. Heavy industrial users are mostly continuous production enterprises, including those in metallurgy, machinery, energy (electricity, petroleum, coal, natural gas, etc.), chemicals, and building materials industries. Their load rates are high and generally stable throughout the year. Compared to other types of users, heavy industrial users consume more electricity on a larger scale and require higher voltage levels connected to the grid. Surveys indicate that many heavy industrial users are classified as first- or second-level loads; short-term power outages can cause significant economic losses and even personal injury accidents, thus requiring extremely high power supply reliability. Light industrial users include textiles, papermaking, bicycles, tobacco, food, and many other industries. Their load characteristics vary considerably, and their requirements for power supply reliability are not entirely the same. Industries such as textiles typically operate on a three-shift system with high load rates, and power supply voltage levels in large and medium-sized textile factories reach 10kV or even higher. The economic losses caused by power outages are substantial, necessitating high power supply reliability.

[0031] Specifically, the technological processes in the steel industry include coking, sintering, power supply, ironmaking, oxygen production, lime mining, auxiliary processes, steelmaking, and rolling. The cement industry's processes include milling, vertical kiln calcination, crushing, and raw material intake. The chemical fiber industry's processes include esterification, polymerization, cutting, spinning, winding, and post-processing. The paper industry's processes include pulping, refining, papermaking, winding, and warehousing. The plastics industry's processes include blown film, cutting, electrothermal processing, extrusion, box forming, ultrasonic molding, punching, hydraulic pressing, crimping, high-speed punching, slitting, winding, slicing, cutting, high-frequency welding, and injection molding. The rubber industry's processes include granulation, foaming, molding, finishing, and shipping. The textile industry's process flow includes pre-spinning, post-spinning, dyeing, winding, weaving, and post-processing.

[0032] In the steel production process, the equipment in the coking, sintering, and power supply stages must first be operational to transport the corresponding products to the ironmaking stage. Then, the oxygen production, auxiliary processes, and lime mining stages operate in unison, combining the products for the next stage, steelmaking. Finally, the steel is output from the steel plant for rolling, thus completing the steelmaking process. Table 1 shows the load ratio of the steel industry at each different stage. Based on the survey, the power consumption of each piece of equipment at different stages can be analyzed to obtain load ratio data.

[0033] Table 1 Load proportions of electricity consumption at different stages in the steel industry

[0034] Process coking process Sintering process Power supply Ironmaking process Oxygen generation process Load ratio 1.78％ 12.7％ 10.16％ 6.77％ 19.48％ Process limestone mine Auxiliary links Steelmaking process Steel rolling process Load ratio 1.69％ 1.69％ 21.17％ 24.56％

[0035] Specifically, the non-ferrous metals and rolling processing industry includes stainless steel pipe production, steel pipe production, and aluminum profile processing. The stainless steel pipe production process includes raw material slitting, rolling, pipe welding, polishing, and packaging. The steel pipe production process includes nitrogen production, casting, extrusion, pipe making, and annealing. The aluminum profile processing process includes casting, extrusion, oxidation, spraying, and water treatment.

[0036] It should be noted that, due to the very small proportion of adjustable loads in industries such as chemical engineering and electronic component manufacturing, this application does not analyze the various process steps in these industries. Furthermore, since the electricity consumption characteristics of different users in the electrical appliance manufacturing and daily necessities industries vary, and their electricity consumption is typically not very high, this application does not divide or predict the process flows for these industries.

[0037] In this embodiment, the typical process flow of electricity consumption in each industry is analyzed to obtain the typical manufacturing process of electricity consumption in each industry.

[0038] It should be noted that the process flow described in this application omits steps that do not inherently require much electricity. Some steps may be crucial and indispensable for product manufacturing in the industry, but if they do not require significant or no electricity, they will not be included in the classification of steps in this invention. The classification of steps in this application is primarily based on the analysis of the electrical energy used by industrial users at each stage, as collected by the power system.

[0039] In this embodiment, determining whether an electrical device is a flexible electrical load based on its response type includes:

[0040] If the electrical equipment is an interruptible load, then the electrical equipment is determined to be a flexible electrical load;

[0041] If the electrical equipment is a transferable load, then it is determined that the electrical equipment is a flexible electrical load during a preset time period or at a preset time point.

[0042] Specifically, the analysis first examines all electrical equipment involved in different processes across various industries, considering the role of each piece of equipment in that process and the impact of its interruption, ultimately classifying its response type. Generally, for the chemical industry, air conditioning equipment in the plant environment is considered a non-adjustable load, while for industries such as steel and cement, air conditioning equipment in the plant area is considered a transferable load.

[0043] In this application, interruptible loads are distinguished from non-adjustable loads; interruptible loads can be interrupted at any time without affecting equipment operation. Transferable loads, on the other hand, refer to equipment whose usage time can be flexibly adjusted. Compared to interruptible loads, they offer greater flexibility in adjustment, such as electric vehicles and air conditioners, whose start-up and operation times can be pre-adjusted based on the overall grid strategy. Interruptible loads, however, primarily refer to the amount of load that can provide emergency support when the grid experiences an emergency.

[0044] Specifically, taking the steel industry as an example, in the coking process, the electrical equipment is classified as a Class I load, requiring uninterrupted power supply 24 hours a day, and therefore belongs to the category of non-adjustable loads. Similarly, the sintering process and power supply process also belong to this category. On the other hand, the ironmaking process, steelmaking process, steel rolling process, and oxygen production process are considered interruptible loads. Relatively speaking, the lime and auxiliary processes in mining are more flexible and belong to the category of transferable loads.

[0045] In this embodiment, for electricity consumption in the steel industry, there are only two scenarios: production interruption and normal production. Therefore, the calculation of load adjustment potential can include both the potential to reduce load and the potential to increase load. The potential to reduce load is obtained by multiplying the electricity response capacity of all links with a day-ahead response time and response type of interruptible or transferable load by their respective electricity consumption percentages. For the steel industry, the response capacity is 1 for all links. Therefore, the calculated potential load reduction is 55.88% for the following links: ironmaking (6.77%), mining / lime (1.69%), auxiliary links (1.69%), steelmaking (21.17%), and rolling (24.56%). The total potential load increase is obtained by solving for the maximum load capacity that the power grid can supply to the steel industry user and subtracting the user's current load.

[0046] In this embodiment, the method for predicting the adjustable potential of industrial electricity load further includes:

[0047] If the electrical equipment is determined to be a flexible electrical load, the response time of the electrical equipment is obtained, and the power supply to the electrical equipment is stopped or the power supply time is adjusted according to the response time; the response time includes the day-ahead response and the intraday response.

[0048] Specifically, considering that the response of some electrical equipment needs to be preset one working day in advance to realize the change of its load, this response time is called day-ahead response, such as in the ironmaking process. Other processes, on the other hand, can be flexibly adjusted according to the grid conditions on the production day; this type of response time can be called intraday response, such as most transferable loads.

[0049] In this embodiment, the method for obtaining the adjustable potential of this type of industrial power consumption based on the power consumption ratio and response capacity includes:

[0050] Within a given response time, the adjustable potential of this type of industrial electricity consumption is the sum of the product of the electricity consumption proportion of each process stage and the response capacity.

[0051] Specifically, response capacity is the proportion of the responsive power of all flexible electrical loads in the current process stage to the total power of all electrical equipment within multiple set time periods. The responsive power of the electrical equipment is obtained by modeling the electrical equipment in each stage.

[0052] In this embodiment, the method for predicting the adjustable potential of industrial electricity load further includes step S4, which follows step S3. Step S4 is as follows:

[0053] Incentive compensation electricity prices are determined based on adjustable potential.

[0054] In this embodiment, the method for determining the response type of electrical equipment in each process step of the process flow includes:

[0055] List the electrical equipment used in each process step and determine the response type of each piece of equipment.

[0056] In this embodiment, for electrical equipment with a response time of one day in advance, the interruption duration and / or interruption time of the electrical equipment need to be determined at least one working day in advance.

[0057] Optionally, for electricity consumption in the steel industry, the response capacity is 1.

[0058] In this embodiment, for certain processes in certain industries, the response capacity value may not necessarily be 1. Taking the electrolytic aluminum industry as an example, analyzing the equivalent circuit of electrolytic aluminum production yields the high-voltage side bus voltage V. AH With DC voltage V B The relationships between them can be constructed using the following formula:

[0059]

[0060] in, Let be the voltage drop across the saturated reactor, and k be the turns ratio of the on-load tap-changing transformer. Through field testing at an aluminum plant, the equivalent circuit model of the plant yielded E = 354.6V and R = 2.016mΩ. Simulations using this data show a positive linear correlation between the active power of the electrolytic aluminum load and the DC voltage.

[0061] Generally speaking, the time required for each tap change of an on-load tap-changing transformer is approximately 7 seconds. If only the turns ratio k of the on-load tap-changing transformer is used to adjust the DC voltage V... B The decrease in electrolytic aluminum load power is abrupt and discontinuous. The on-load tap-changing transformer has multiple taps, with each tap having an adjustment range of 1.25%.

[0062] Based on the modeling, the DC voltage is controlled by adjusting the turns ratio of the on-load tap-changing transformer. The DC voltage is stepped, resulting in a stepped power output for the electrolytic aluminum load, with each transition cycle lasting 7 seconds. If the tap changer of the on-load tap-changing transformer is continuously adjusted, the low-voltage side bus voltage V... AL The voltage V changes to 0.9875 pu, 0.9750 pu, 0.9625 pu, 0.9500 pu, and 0.9375 pu at 7s, 14s, 21s, 28s, and 35s respectively. d The values ​​also change to 0.9875pu, 0.9750pu, 0.9625pu, 0.9500pu, and 0.9375pu respectively, while the electrolytic aluminum load power changes to 0.9713pu, 0.9431pu, 0.9152pu, 0.8878pu, and 0.8608pu respectively.

[0063] The saturated reactor can be considered a controllable nonlinear impedance. Its working principle is to use the current in the DC winding to change the reactance of the AC winding. Its adjustment speed is very fast, controllable within 500ms. In the DC voltage regulation of electrolytic aluminum, the on-load tap-changing transformer plays a coarse adjustment role, while the saturated reactor plays a fine adjustment role. To reduce the number of tap changer operations of the on-load tap-changing transformer and extend its lifespan, the adjustment range of the saturated reactor, which plays a fine adjustment role, should not be less than two tap differences of the on-load tap-changing transformer, nor less than the voltage of the anode effect of one electrolytic cell (40-50V), typically 50-70V. The adjustment is achieved by controlling the saturated reactor. When the voltage changes by 60V, the DC voltage V BWith a voltage change of 90V, the electrolytic aluminum load power becomes 0.8661 pu. If both an on-load tap-changing transformer and a saturated reactor are used for regulation simultaneously, calculations show that the electrolytic aluminum load power becomes 0.8661 pu, 0.8394 pu, 0.8131 pu, 0.7873 pu, 0.7618 pu, and 0.7367 pu at 500ms, 7s, 14s, 21s, and 28s, respectively. This means the frequency regulation capacity provided by this electrolytic aluminum load at 500ms, 7s, 14s, 21s, and 28s is 13.39%, 16.06%, 18.69%, 21.27%, 23.82%, and 26.33%, respectively. In conclusion, continuous adjustment of the electrolytic aluminum load can be achieved through continuous voltage adjustment; a DC voltage adjustment of 0.1 pu results in a 24.7% adjustment of the electrolytic aluminum load.

[0064] This application also provides an industrial power load adjustable potential prediction system (not shown), which applies the above-described industrial power load adjustable potential prediction method.
