Technical Field

[0001] The present invention relates to the field of electricity, and particularly to a comprehensive energy supply method, device, and storage medium for factories. Background Art

[0002] With the transformation of the global energy structure and the deepening of the concept of sustainable development, energy management in semiconductor manufacturing factories, such as polysilicon factories, which are important production bases for semiconductor production, has attracted increasing attention. Semiconductor manufacturing, such as polysilicon production, is a process with high energy consumption and high emissions. Traditional energy management methods are difficult to meet the increasingly strict environmental protection requirements and market competition needs. Therefore, exploring an efficient, environmentally friendly, and flexible energy management method has become an important issue faced by semiconductor manufacturing factories.

[0003] Currently, a comprehensive energy collaborative system can be used to supply energy to semiconductor manufacturing factories. By integrating various energy resources, the comprehensive energy collaborative system expects to achieve efficient utilization and flexible scheduling of energy. However, in actual applications, due to the often close coupling relationship between the energy supply end and the energy consumption end, this coupling relationship leads to inflexible energy scheduling, poor flexibility of the comprehensive energy collaborative system, and inability to meet the requirements of efficient utilization and flexible scheduling of energy when the comprehensive energy collaborative system is pre-designed.

[0054] To make the above objects, features, and advantages of the present application more obvious and understandable, the following will describe in detail the specific implementation manners of the present application with reference to the accompanying drawings.

[0055] In the following description, many specific details are set forth to facilitate a thorough understanding of the present application. However, the present application may be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the connotation of the present application. Therefore, the present application is not limited by the specific embodiments disclosed below.

[0056] In a traditional polysilicon factory energy system, there is often a tight coupling relationship between the energy supply end and the energy consumption end. This coupling relationship results in inflexible energy scheduling and difficulty in adapting to changes in energy demand during the production process. At the same time, due to the lack of effective utilization of renewable energy, the energy utilization efficiency of the traditional energy system is low, and the production cost is high. In addition, with the continuous expansion of the scale of polysilicon factories and the increasing complexity of production processes, the stability and reliability of the energy system also face severe challenges.

[0057] Currently, an integrated energy collaborative system can be used to supply energy to a polysilicon factory. By integrating various energy resources, the integrated energy collaborative system is expected to achieve efficient energy utilization and flexible scheduling. However, in actual applications, the integrated energy collaborative system often lacks consideration of decoupling between the energy supply end and the energy consumption end during design, resulting in poor system flexibility, difficulty in expansion and upgrade.

[0058] The integrated energy collaborative system includes green energy, such as renewable energy sources like wind energy and solar energy. These renewable energy sources have the advantages of being clean, environmentally friendly, and sustainable, and are of great significance for reducing carbon emissions and production costs in polysilicon factories. However, the volatility and intermittency characteristics of renewable energy also pose new challenges to energy management. How to effectively integrate renewable energy into the energy system of a polysilicon factory and achieve efficient energy utilization and flexible scheduling is an urgent problem to be solved in the current industrial energy management field.

[0059] That is to say, currently, due to the often tight coupling relationship between the energy supply end and the energy consumption end, this coupling relationship leads to inflexible energy scheduling, and the integrated energy collaborative system has poor flexibility and cannot meet the requirements of efficient energy utilization and flexible scheduling when the integrated energy collaborative system was pre-designed.

[0060] Based on this, the present application provides a comprehensive energy supply method for factories, which includes: constructing an energy supply end component system for supplying energy to the factory and an energy consumption end component system for the factory to consume energy. The energy supply end component system includes multiple energy supply components, and the energy consumption end component system includes multiple workshop components. That is, the energy supply end and the energy consumption end are constructed as multiple separate components to achieve the decoupling of energy supply and energy consumption; constructing a first topological relationship for multiple energy supply components to perform multi-energy coupling according to the energy flow relationship between multiple energy supply components, and constructing a second topological relationship for multiple workshop components to perform multi-energy coupling according to the energy flow relationship and material flow relationship between multiple workshop components. That is, the relationships between the decoupled components form topological relationships through the energy flow relationship or material flow relationship between the components; constructing a connection relationship between multiple energy supply components in the energy supply end component system and multiple workshop components in the energy consumption end component system through the first topological relationship and the second topological relationship, so as to use the connection relationship for the energy supply component to supply energy to the workshop component. That is, using the first topological relationship and the second topological relationship to achieve flexible connection of multiple components included in the decoupled energy supply end and energy consumption end, thereby realizing flexible energy supply. That is to say, the method provided by the present application can decouple the energy supply end and the energy consumption end, realize flexible connection and independent operation between the energy supply end and the energy consumption end, optimize the energy configuration and utilization efficiency, and meet the requirements of efficient energy utilization and flexible scheduling of energy when pre-designing a comprehensive energy collaborative system.

[0061] To better understand the technical solutions and technical effects of the present application, specific embodiments will be described in detail below with reference to the accompanying drawings.

[0062] Reference Figure 1 As shown, it is a schematic flowchart of a comprehensive energy supply method for factories provided by an embodiment of the present application. The method includes the following steps:

[0063] S101, construct an energy supply end component system for supplying energy to the factory and an energy consumption end component system for the factory to consume energy.

[0064] In the embodiment of the present application, the factory is a semiconductor manufacturing factory, such as a polysilicon factory. The factory can include an energy supply end and an energy consumption end. To achieve the decoupled design of the energy supply end and the energy consumption end, an energy supply end component system for supplying energy to the factory and an energy consumption end component system for the factory to consume energy can be constructed. The energy supply end component system includes multiple energy supply components, and the energy consumption end component system includes multiple workshop components.

[0065] Specifically, the multiple energy supply components include an electric energy supply component and a heat energy supply component, that is, the energy supply end can supply electric energy and heat energy.

[0066] As a possible implementation, the multiple energy supply components include a power grid component, a self-owned power plant component, an energy storage component, a photovoltaic power generation component, and a wind power generation component, as shown in Figure 2 . The power grid component, the self-owned power plant component, the energy storage component, the photovoltaic power generation component, and the wind power generation component are power supply components, and the self-owned power plant component is a heat supply component.

[0067] The following is a specific introduction to the multiple energy supply components.

[0068] As the main power supply source, the self-owned power plant component not only has sufficient power generation capacity to meet the basic power demand of the factory, but also provides heat supply for the factory through a cogeneration mechanism. In addition, the design of the self-owned power plant needs to consider the flexibility of maintenance and expansion to ensure that it can be upgraded or repaired without affecting other components.

[0069] The wind power generation component can adaptively adjust the power generation efficiency according to weather and environmental conditions. The wind turbine groups included in the wind power generation component operate independently of each other. Even if some wind turbine groups fail, it will not affect the normal operation of the overall wind power generation component.

[0070] The photovoltaic power generation component has an autonomous adjustment ability and can dynamically optimize the power generation performance according to real-time lighting conditions. Each photovoltaic panel included in the photovoltaic power generation component can operate independently, ensuring that even if a single photovoltaic panel fails, it will not affect the stability of the overall photovoltaic power generation component.

[0071] The energy storage component can independently manage the storage and release of electric energy and has a fast response ability to changes in power demand. The internal design of the energy storage component is multiple independently controllable units, and each unit can be individually managed and scheduled, thus ensuring the flexibility and stability of the energy storage system.

[0072] As a backup power source, the power grid component automatically intervenes in power supply when the self-owned power plant component, the wind power generation component, or the photovoltaic power generation component cannot meet the load demand. This design ensures that the factory can still obtain stable power supply in the case of insufficient power generation by the self-owned power plant component, the wind power generation component, or the photovoltaic power generation component, thus ensuring the continuity and stability of the overall power system.

[0073] That is to say, the integrated energy of the energy supply end is designed into relatively independent components, namely, the power grid component, the self-owned power plant component, the energy storage component, the photovoltaic power generation component, and the wind power generation component. Among them, the scale and layout of the wind power generation component and the photovoltaic power generation component should be reasonably designed according to the local wind energy and solar energy resource conditions. The access of these renewable energy components such as the wind power generation component and the photovoltaic power generation component can not only reduce the dependence on the traditional power grid, but also effectively reduce the carbon emissions in the polysilicon production process; the capacity and type of the energy storage component should be reasonably selected according to the power demand fluctuation of the factory and the peak-valley electricity price mechanism. After the decoupling design, each component can independently manage its energy supply to ensure the stable operation of the energy supply end under complex working conditions. The entire energy supply end is based on the modular design concept, and each component has independent equipment characteristics, such as power generation capacity, energy conversion efficiency, etc., and can be flexibly combined or adjusted according to actual needs, and will not affect the normal operation of other parts during maintenance, upgrade or expansion. This improves the reliability, maintainability and expandability of the energy supply end.

[0074] The multiple workshop components include the electric energy demand workshop component and the thermal energy demand workshop component, that is, there are demands for electric energy and thermal energy at the energy consumption end.

[0075] As a possible implementation manner, the multiple workshop components include the finished product workshop component, the reduction workshop component, the raw material workshop component, the cold hydrogeneration workshop component, and the auxiliary workshop component, as shown in Figure 2 shown.

[0076] The energy consumption demands of the energy consumption end are designed into relatively independent components, namely, the finished product workshop component, the reduction workshop component, the raw material workshop component, the cold hydrogeneration workshop component, and the auxiliary workshop component. Through the decoupling design, each workshop component can operate independently and flexibly adjust its energy demand according to its own production load, realizing the independence and flexibility among different workshop components during the production process.

[0077] S102. Construct a first topological relationship of multi-energy coupling for multiple energy supply components according to the energy flow relationship between the multiple energy supply components.

[0078] In the embodiment of the present application, after the energy supply end is designed as multiple energy supply components, a first topological relationship of multi-energy coupling for multiple energy supply components can be constructed according to the energy flow relationship between the multiple energy supply components.

[0079] Specifically, when multiple energy supply components include a power grid component, a self - contained power plant component, an energy storage component, a photovoltaic power generation component, and a wind power generation component, the energy flow relationships include an electric energy flow relationship, a light energy flow relationship, and a wind energy flow relationship. Then, the first topological relationship for multi - energy coupling constructed based on the electric energy flow relationship, light energy flow relationship, and wind energy flow relationship among the power grid component, self - contained power plant component, energy storage component, photovoltaic power generation component, and wind power generation component is that the power grid component is used to supply electric energy to the self - contained power plant component, energy storage component, photovoltaic power generation component, and wind power generation component; the self - contained power plant component is used to supply electric energy and heat energy; the photovoltaic power generation component is used to convert light energy into electric energy; the wind power generation component is used to convert wind energy into electric energy; and the energy storage component is used to store and release electric energy.

[0080] That is to say, according to the energy flow relationships among the components at the energy supply end, a multi - energy coupling topological structure including wind energy, light energy, and electric energy flow relationships is constructed. This topological structure should be able to clearly reflect the collaborative and complementary relationships among different energy supply components, as well as the transmission and distribution paths of energy in the system. The specific energy flow relationships at the energy supply end are as follows: (1) As the main power source, the power grid provides basic power guarantee for the entire energy supply end. It not only provides necessary electric energy support for the self - contained power plant, but also directly provides stable power supply for other energy conversion and storage facilities, such as wind power, photovoltaic power, and energy storage. (2) The self - contained power plant plays an important role at the energy supply end. It can not only directly provide power for the factory, but also generate heat (steam) through the combined heat and power generation mechanism. This heat energy can be used to meet the heat energy demand in the factory production process. The operation of the self - contained power plant complements the power supply of the power grid, ensuring the stability and reliability of power supply. (3) As representatives of renewable energy, wind power and photovoltaic power also have a place at the energy supply end. Wind power uses wind resources to generate electricity, and photovoltaic power converts light energy into electric energy through solar panels. The access of these two renewable energy sources not only reduces the dependence on the traditional power grid, but also helps to reduce carbon emissions and realize the utilization of green energy. (4) The energy storage component plays a role in regulating and balancing at the energy supply end. When the power supply is sufficient, the energy storage component can absorb the excess electric energy for storage; while during peak power demand or insufficient power supply, it can release the stored electric energy to supplement the power supply.

[0081] The first topological relationship describes the wind energy, light energy, and electric energy flow relationships among the components at the energy supply end. By constructing this topological relationship, the collaboration and complementarity of multiple energy supply methods can be realized, improving the stability and reliability of the energy system. At the same time, this topological relationship can also facilitate energy scheduling and optimization, reducing production costs and carbon emissions.

[0082] Next, a quantitative and specific introduction to the first topological relationship will be given.

[0083] The power generation of the self - contained power plant components can be calculated by the following formula:

[0084] P powerplant = m·LHV·η CP

[0085] Wherein, P powerplant is the power generation of the self - contained power plant components, with the unit of kW; m is the fuel mass flow rate, with the unit of kg / s; LHV is the lower heating value of the fuel, with the unit of kJ / kg; η CP is the thermal energy conversion efficiency.

[0086] The power generation of the wind power generation components can be expressed by the following formula:

[0087]

[0088] Wherein, P wind is the power generation of the wind turbines included in the wind power generation components, with the unit of kW; P R is the rated power generation per unit time of the wind turbine, with the unit of kWh; v is the actual wind speed at the hub height of the wind turbine, with the unit of m / s; a, b, c, d, e, f are fitting coefficients; v in and v out are the cut - in wind speed and cut - out wind speed of the wind turbine respectively, with the unit of m / s; v R,i and v R,j are the upper limit wind speed and lower limit wind speed of the rated wind speed range of the wind turbine respectively, with the unit of m / s.

[0089] The power generation of the photovoltaic power generation components can be calculated by the following formula:

[0090] P solar = A C ·GI T ·η PV ·f PV

[0091] Wherein, P solar is the power generation of the photovoltaic power generation components, with the unit of kW; A C is the area of the PV panel, with the unit of m 6 ; GI T is the total irradiance, with the unit of W / m 6 ; η PV is the reference efficiency of the solar cell panel; f PV is the derating factor, which is the efficiency loss caused by dust, shading, rain, snow, etc.

[0092] The charge - discharge power of the energy storage components can be expressed as:

[0093] P storage = ±η charge / discharge ·ΔE / Δt

[0094] Among them, P storage is the charging and discharging power of the energy storage component, with the unit of kW; η charge / discharge is the charging / discharging efficiency; ΔE is the energy change amount, with the unit of kWh; Δt is the time interval, with the unit of h.

[0095] The electric power of the power grid component can be expressed as:

[0096] P buy = P total_g - (P powerplant + P wind + P solar + P storage )

[0097] Among them, P buy is the power purchase of the power grid component, with the unit of kW; P total_g is the total power demand, with the unit of kW; P powerplant , P wind , P solar , P storage are respectively the power generation of the self-owned power plant component, the wind power generation component power, the photovoltaic power generation component power, and the charging and discharging power of the energy storage component.

[0098] Based on the decoupling design of the energy supply end and the construction of the first topological relationship, the energy flow of the entire energy supply end forms a multi-energy complementary and dynamically balanced closed-loop system. Energy is efficiently transferred and distributed through coupling and coordination among various links, ensuring the stable operation of the polysilicon factory and the sustainability of production. The process of adjusting the energy coordination strategy according to the first topological relationship is as follows: The wind power generation component and the photovoltaic power generation component monitor the power generation fluctuations in real time through the consistency algorithm and adjust the charging and discharging behavior of the energy storage component; The self-owned power plant component adjusts the output in a timely manner to make up for the fluctuations when the power generation of the wind power generation component and the photovoltaic power generation component is unstable, realizing the flexible matching of multi-energy flow. When the self-owned power plant component cannot meet the load demand, the power grid component quickly intervenes to provide stable power support. Through the intelligent scheduling algorithm, the power generation characteristics and energy demands of each energy supply component are analyzed in real time, and the energy flow direction is dynamically adjusted according to the fluctuation laws of wind energy and light energy and the capacity constraints of the energy storage component, ensuring that the energy supply is always in the optimal state. This multi-energy coupling topological structure effectively alleviates the influence of the volatility of wind energy and light energy, realizes fast and accurate energy matching and dynamic optimization, and at the same time provides convenience for energy management and monitoring, ensuring the efficient and reliable operation of the energy supply system.

[0099] S103. Construct a second topological relationship for multi-energy coupling of multiple workshop components according to the energy flow relationship and material flow relationship among multiple workshop components.

[0100] In the embodiments of the present application, after the energy-consuming end is designed as multiple workshop components, a second topological relationship for multi-energy coupling of the multiple workshop components can be constructed according to the energy flow relationship and material flow relationship among the multiple workshop components.

[0101] The second topological relationship describes the energy and material flow relationships among the various workshop components of the energy-consuming end. By constructing such a topological relationship, the energy configuration and utilization efficiency in the production process can be optimized, and energy consumption and emissions can be reduced. At the same time, this topological relationship can also facilitate production scheduling and optimization, improving production efficiency and product quality.

[0102] Specifically, when the multiple workshop components include a finished product workshop component, a reduction workshop component, a raw material workshop component, a cold hydrogeneration workshop component, and an auxiliary workshop component, the energy flow relationship includes a heat energy flow relationship and an electric energy flow relationship. The material flow relationship is the material transfer relationship among the multiple workshop components.

[0103] For example, in the process of preparing trichlorosilane (TCS), a large amount of silicon tetrachloride (STC) is produced as a by-product. The polysilicon production line uses the cold hydrogeneration method to reconvert STC into TCS required for polysilicon production, which not only solves the problem of by-products but also realizes green chemical economy. Cold hydrogeneration is to add Si powder and a catalyst into a fluidized bed reactor, and after mixing STC with H 2 and introducing it into the reactor, the reaction occurs under the catalytic action to obtain TCS. The reaction temperature is generally controlled at 500 - 600 °C, and the conversion rate is between 25% - 35%, and continuous production can be carried out. The reaction products trichlorosilane and unreacted silicon tetrachloride are collected through a series of condensation systems, and trichlorosilane and silicon tetrachloride are separated through a chlorosilane rough separation system, and silicon tetrachloride continues to enter the circulation system as a reaction raw material. Therefore, the manufacturing process of preparing trichlorosilane and the manufacturing process of cold hydrogeneration of silicon tetrachloride are decoupled into two independent workshop components for execution, that is, the raw material workshop component and the cold hydrogeneration workshop component for execution. There is a material flow relationship of trichlorosilane and silicon tetrachloride between the raw material workshop component and the cold hydrogeneration workshop component.

[0104] The second topological relationship for multi-energy coupling of the multiple workshop components constructed according to the heat energy flow relationship, electric energy flow relationship, and material flow relationship among the finished product workshop component, reduction workshop component, raw material workshop component, cold hydrogeneration workshop component, and auxiliary workshop component is that the finished product workshop component is used to obtain electric energy, the reduction workshop is used to convert the raw materials of the raw material workshop into the finished products of the finished product workshop component, the reduction workshop is used to obtain electric energy and transfer heat energy to the raw material workshop, the raw material workshop is used to obtain electric energy and transfer heat energy to the auxiliary workshop, the cold hydrogeneration workshop component is used to obtain electric energy, provide electric energy to the auxiliary workshop component, and obtain heat energy, and the auxiliary workshop component is used to obtain electric energy and obtain heat energy. Refer to Figure 2As shown, the material flow relationship between different workshops is clearly demonstrated, laying a theoretical foundation for improving production efficiency and resource utilization rate.

[0105] That is to say, according to the energy and material flow relationship among the components at the energy consumption end, a multi-energy coupling topological structure including electric energy and thermal energy is constructed. This topological structure should be able to clearly reflect the energy consumption and material flow conditions between different workshops, as well as the transmission and utilization efficiency of energy in the production process. Through the decoupled design of the multi-energy coupling topological relationship at the energy consumption end, the material and energy flows between workshops are optimized, reducing unnecessary energy waste. The resource utilization efficiency of each workshop is significantly improved, energy consumption is reduced, the production process is optimized, and the overall production efficiency and product quality are also enhanced.

[0145] S104. Construct the connection relationship between multiple energy supply components in the energy supply end component system and multiple workshop components in the energy consumption end component system through the first topological relationship and the second topological relationship, so as to use the connection relationship for the energy supply from the energy supply components to the workshop components.

[0146] In the embodiment of the present application, after obtaining the first topological relationship between multiple energy supply components at the energy supply end and the second topological relationship between multiple workshop components at the energy consumption end, the connection relationship between multiple energy supply components in the energy supply end component system and multiple workshop components in the energy consumption end component system can be constructed through the first topological relationship and the second topological relationship, so as to use the connection relationship for the energy supply from the energy supply components to the workshop components.

[0147] Considering that multiple energy supply components include electrical energy supply components and thermal energy supply components, and multiple workshop components include electrical energy demand workshop components and thermal energy demand workshop components, the connection relationship includes an electrical connection relationship and a thermal connection relationship. Therefore, the electrical connection relationship between the electrical energy supply components in the energy supply end component system and the electrical energy demand workshop components in the energy consumption end component system is constructed through the first topological relationship and the second topological relationship, so as to use the electrical connection relationship for the electrical energy supply from the electrical energy supply components to the electrical energy demand workshop components; the thermal connection relationship between the thermal energy supply components in the energy supply end component system and the thermal energy demand workshop components in the energy consumption end component system is constructed through the first topological relationship and the second topological relationship, so as to use the thermal connection relationship for the thermal energy supply from the thermal energy supply components to the thermal energy demand workshop components.

[0148] Specifically, by using the first topological relationship and the second topological relationship, an electrical energy connection relationship is established among the power grid components, self-owned power plant components, energy storage components, photovoltaic power generation components, wind power generation components, and the finished product workshop components, reduction workshop components, raw material workshop components, cold hydrogeneration workshop components, and auxiliary workshop components, so as to utilize the electrical energy connection relationship to supply electrical energy from the power grid components, self-owned power plant components, energy storage components, photovoltaic power generation components, and wind power generation components to the finished product workshop components, reduction workshop components, raw material workshop components, cold hydrogeneration workshop components, and auxiliary workshop components; by using the first topological relationship and the second topological relationship, a thermal energy connection relationship is established between the self-owned power plant components and the raw material workshop components, cold hydrogeneration workshop components, and auxiliary workshop components, so as to utilize the thermal energy connection relationship to supply thermal energy from the self-owned power plant components to the raw material workshop components, cold hydrogeneration workshop components, and auxiliary workshop components. Refer to Figure 2 as shown.

[0149] In the embodiments of the present application, in order to enable multiple energy supply components to provide stable electrical energy support and thermal energy support to multiple workshop components through the electrical energy connection relationship and the thermal energy connection relationship, the total supply of the energy supply end component system and the total demand of the energy consumption end component system can be calculated according to the first topological relationship, the second topological relationship, and the connection relationship; with the goal of making the total supply equal to the total demand, the operating states of multiple energy supply components in the energy supply end component system in the energy coordination strategy are calculated.

[0150] Specifically, considering that multiple energy supply components supply electrical energy and thermal energy to multiple workshop components, the total supply includes the total electrical energy supply and the total thermal energy supply, and the total demand includes the total electrical energy demand and the total thermal energy demand.

[0151] The total supply at the energy supply end is:

[0152] E total_g = E buy + E powerplant + E wind + E solar + E storage

[0153] Q total_g = ηE powerplant

[0154] where, E total_g is the total electrical energy supply, E buy is the electricity purchased from the power grid, E powerplant is the power generation of the self-owned power plant components, E wind is the power generation of the wind power generation components, E solar is the power generation of the photovoltaic power generation components, E storage is the charge or discharge amount of the energy storage components, Q total_gis the total heat energy supply, and η is the heat-electricity ratio of cogeneration.

[0155] The total demand at the energy consumption end is:

[0156] E total_c = E prod + E red + E raw + E ch + E aux

[0157]

[0158] Q total_c = Q raw + Q ch + Q aux

[0159] Among them, E total_c is the total electricity demand, E prod is the power consumption of components in the finished product workshop, E red is the power consumption of components in the reduction workshop, E raw is the power consumption of components in the raw material workshop, E ch is the power consumption of components in the cold hydrogeneration workshop, E aux is the power consumption of components in the auxiliary workshop, is the basic power of the cold hydrogeneration reactor, t ch is the operating time of the cold hydrogeneration reactor, α is the coefficient of the influence of the auxiliary workshop on the power of the cold hydrogeneration workshop, Q total_c is the total heat energy demand, Q raw is the heat consumption of components in the raw material workshop, Q ch is the heat consumption of components in the cold hydrogeneration workshop, Q aux is the heat consumption of components in the auxiliary workshop.

[0160] Taking the equality of the total supply and the total demand as the goal, the supply-demand balance relationship of electric energy and heat energy between the energy supply end and the energy consumption end is as follows:

[0161] E total_g = E total_c

[0162] Q total_g = Q total_c

[0163] Among them, E total_g is the total electricity supply; E total_c is the total electricity demand; Q total_g is the total heat energy supply; Q total_c is the total heat energy demand.

[0164] In the embodiments of the present application, the real-time supply of the energy supply end component system, the real-time demand of the energy consumption end component system, and the stored energy can be obtained; the energy coordination strategy is adjusted according to the real-time supply, real-time demand, and stored energy, and the operating states of multiple energy supply components in the energy supply end component system are adjusted according to the energy coordination strategy.

[0165] Specifically, sensors and data acquisition systems can be installed to monitor the energy states of the energy supply end and the energy consumption end in real time to achieve fast matching. The decoupling design can adjust the charge and discharge strategies of the energy storage components in real time according to the changes in energy demand to ensure the balance between supply and demand and the stability of the system. By obtaining the supply, demand, and storage status of electrical energy, thermal energy, and other energy data, and using historical data to analyze the balance between supply and demand, an optimized energy coordination strategy is formulated, such as storing energy when the power is excessive and releasing energy when it is insufficient, adjusting the power load of the polysilicon production workshop, optimizing the power distribution between the power grid and the self-owned power plant, and optimizing the proportion of renewable energy use according to the wind power generation and photovoltaic power generation conditions, thereby constituting an efficient and flexible energy management system to ensure the balance between energy supply and demand and the stable operation of the system.

[0166] In practical applications, based on the decoupling design of the energy supply end and the energy consumption end, the flexible connection and independent operation between the two are realized by adjusting the connection relationship between the energy supply end component system and the energy consumption end component system. Specifically, the following measures can be taken to achieve the decoupling design: Adopt the modular design concept to design the energy supply end and the energy consumption end into relatively independent components. Each component can be flexibly combined and replaced according to actual needs to achieve the scalability and upgradability of the system. Adopt the standardized interface design to ensure the smooth connection and communication between different components. By formulating unified interface standards and communication protocols, the interoperability and interchangeability between components are realized. Adopt intelligent monitoring and control technologies to achieve real-time monitoring and intelligent control of each component at the energy supply end and the energy consumption end. By collecting and analyzing the operation data of each component, the energy scheduling and distribution strategies are adjusted in a timely manner to ensure the stable operation and efficient utilization of the system.

[0167] As an example, with the goal of minimizing costs, an optimization schedule is carried out with a 24-hour cycle. The hourly electricity and heat demands of the energy consumption end are as Figure 3 shown, and the power generation output distribution plan of the energy supply end is obtained, as Figure 4As shown in the figure. By independently regulating each energy source and flexibly adjusting the energy distribution, giving priority to the consumption of low-cost new energy, the new energy consumption rate is as high as 82%. The energy supply side not only effectively reduces the overall energy consumption cost, but also significantly reduces the use of fossil fuels, thereby reducing carbon emissions. This decoupling design enables each energy module to operate independently and efficiently through precise control of supply-demand balance and multi-energy coordination mechanism, and quickly adjusts the energy transmission path and distribution strategy under complex load fluctuation conditions. The decoupled system has higher flexibility and scheduling ability, ensuring the optimal energy flow path between modules, thus achieving the optimal overall operation configuration and maximizing the resource utilization efficiency.

[0168] In practical applications, it can also be customized and optimized according to specific requirements. For example, the configuration and operation mode of the energy supply end component system can be adjusted according to the production characteristics and energy requirements of different workshops; the energy scheduling and distribution strategy can be optimized according to the changes in external energy supply and market price fluctuations; advanced monitoring and control technologies can be used to achieve real-time monitoring and intelligent management of the energy system.

[0169] From the above description, it can be seen that the integrated energy supply method for factories provided by the embodiments of the present application designs the connection relationship between the energy supply end component system and the energy consumption end component system in an adjustable and replaceable manner, enabling the energy system to flexibly respond to the changes in energy requirements of different workshops and external energy supply fluctuations, and significantly improving the dynamic adaptability of the system. The decoupling design realizes efficient collaboration by independently optimizing each subsystem, reduces energy transmission losses, improves the overall energy efficiency of the system, thereby reducing production costs and carbon emissions. Through independent management and efficient collaboration, the decoupling design enhances the fault tolerance ability of the integrated energy management system, ensuring that the failure of a single component does not affect the operation of the entire system, and significantly improving the stability and reliability of the system. The decoupling design facilitates the expansion and upgrade of future systems. Through modular design, each component can be flexibly adjusted and expanded according to requirements, effectively supporting the long-term development and technological upgrade of the system. It can also be customized and optimized according to specific requirements, and advanced monitoring and control technologies are used to achieve real-time monitoring and intelligent management of the energy system, improving the operation efficiency of the system and the accuracy of energy scheduling.
