[0002] With the large-scale development of renewable energy such as wind power and photovoltaic, the problem of abandoned wind and light is becoming increasingly prominent, resulting in a large amount of clean energy waste. At the same time, the demand for heating in the northern region is huge in winter, and the traditional coal and gas heating method has high energy consumption and large carbon emissions. Abandoned wind and light heating converts the off-grid wind and photovoltaic power into heat energy, realizing the dual goals of "abandoned energy utilization + clean heating", and is the key path to solve the problem of renewable energy consumption and traditional heating pollution.

DETAILED DESCRIPTION

[0018] In order to make the purpose, technical scheme and advantages of the embodiments of the application clearer, the technical scheme in the embodiments of the application will be described clearly and completely in conjunction with the drawings in the embodiments of the application. Obviously, the described embodiments are part of the embodiments of the application, not all the embodiments. The components of the embodiments of the application described and shown in the drawings can be arranged and designed in various different configurations.

[0019] Therefore, the following detailed description of the embodiments of the application provided in the drawings is not intended to limit the scope of the claimed application, but only represents selected embodiments of the application. All other embodiments obtained by those skilled in the art without creative labor based on the embodiments in the application belong to the scope of protection of the application.

[0020] Some embodiments of the present application will be described in detail with reference to the drawings. The following examples and features in the examples can be combined with each other without conflict.

[0021] Example one Figure 1 A flow chart of an intelligent high-efficiency heating method for consuming and abandoning wind and light is provided for the embodiments of the present application, as shown in Figure 1 The method specifically comprises the following steps: Step S102, obtaining the electric energy parameters of abandoned wind and light and the heat load demand value of the user end.

[0022] To achieve the dual goals of "abandoned energy utilization + clean heating", the embodiments of the present application need to collect real-time data from two key dimensions: on the one hand, the energy supply side, i.e. the electric energy parameters of abandoned wind and photovoltaic power, the core of which is the real-time and fluctuating abandoned power value (unit: kW); on the other hand, the energy demand side, i.e. the heat load demand value (unit: kW) of the user end, which reflects the instantaneous power required to supplement the heating at present. By continuously and synchronously obtaining these two types of dynamic power parameters, the intelligent high-efficiency heating system for consuming and abandoning wind and light (i.e. the execution subject of the embodiments of the present application) can perceive "how much fluctuating clean electric energy is available for utilization" and "how high the heating power is required by the user end" in real time, providing accurate quantitative input basis for subsequent optimization decisions such as power matching, storage and distribution of energy conversion.

[0023] Step S104, based on the electric energy parameters, calling the preset power adaptation strategy to dynamically control the number of operating modules of the modular electric heating device to adapt to the fluctuation of abandoned power and convert electric energy into heat energy.

[0024] In view of the random and fluctuating characteristics of abandoned wind and light electric power (hereinafter referred to as abandoned power), the system presets a power adaptation strategy. The core logic of this strategy is to dynamically and flexibly determine the number of electric heating modules in operation (the modular electric heating device is composed of multiple electric heating modules) according to the size of the real-time acquired abandoned power. Its essence is to realize the real-time matching of abandoned power and electric heating power. For example, when the abandoned power is high, more electric heating modules are automatically operated to provide higher total heating power, so as to fully absorb electric energy; when the abandoned power decreases, the number of operating modules is reduced, so that the total heating power decreases. Through this dynamic control, the electric energy-heat energy conversion power can track and match the fluctuation curve of the abandoned power in real time, thereby maximizing the instantaneous conversion of unstable electric energy resources into heat energy, and significantly improving the abandoned power consumption rate.

[0025] Step S106, the converted heat energy is transferred to the circulating water through the heat exchange medium, and according to the temperature of the heated circulating water, it is delivered to the corresponding temperature zone of the layered heat storage device with at least two independent temperature zones for storage and insulation.

[0026] In the embodiment of the present application, the electric heating device generates heat energy at a certain power, which is efficiently transferred to the heating circulating water through an intermediate heat exchange medium (such as high-temperature heat-conducting oil), which helps to improve the heat exchange efficiency. Then, the circulating water heated to different temperatures will be strategically delivered to the layered heat storage device. Specifically, the device is divided into at least two (such as high-temperature zone, low-temperature zone) independent and thermally isolated temperature zones. The system delivers the circulating water to the temperature-matched temperature zone inlet for storage according to the actual outlet water temperature. This temperature zoning storage method effectively avoids the ineffective mixing of different grades of heat energy, so that the stored heat energy (in the form of hot water) can maintain its available temperature level. The device essentially constitutes a heat energy "buffer pool" and "energy storage library" with temperature stratification, which not only stores heat energy, but more importantly, classifies and stores different grades of heat energy, providing adjustment capability for subsequent precise and stable heat energy output according to user demand for power and temperature.

[0027] Step S108, based on the heat load demand value and the heat storage state parameters of each temperature zone in the layered heat storage device, a preset supply-demand matching strategy is called to determine the heating scheme.

[0028] The heating scheme includes: the priority and proportion of calling heat storage energy from each independent temperature zone of the layered heat storage device. The heat storage state parameters of each temperature zone in the layered heat storage device include: the average temperature and available heat storage capacity of hot water in each temperature zone. The available heat storage capacity of any temperature zone = effective water storage volume of the temperature zone × density of water × specific heat capacity of water × (real-time average temperature of the temperature zone - minimum acceptable return water temperature of the heating system).

[0029] After obtaining the heat load demand value and the heat storage state parameters of each temperature zone in the layered heat storage device, it is known that the heat load demand value quantifies the total heating power required by the current heating system, while the heat storage state parameters of each temperature zone in the layered heat storage device include the average temperature and available heat storage capacity of hot water in each independent temperature zone, which accurately describes the inventory status of different grades of heat energy. Next, a preset supply-demand matching strategy is called, which is a complete and hierarchical decision rule. Its core logic includes the following two layers: The first layer: call priority rules. This establishes the basic energy call sequence. The most typical and efficient rule is "call by descending average temperature of temperature zones", that is, preferentially call the temperature zone with the highest average temperature (such as the high-temperature zone), and then sequentially call the next temperature zone with a higher temperature (such as the medium-temperature zone) when the available heat storage of the high-temperature zone is insufficient to meet the total demand. This ensures that high-quality heat energy is preferentially utilized when possible to maintain system overall efficiency and heating stability.

[0030] The second layer: call proportion calculation rules. First, determine whether the available heat storage of the highest priority temperature zone (such as the high-temperature zone) is greater than or equal to the current heating load demand value. If yes, the heating scheme is that 100% of the heating load demand is met by the high-temperature zone alone. At this time, there is no proportion allocation problem, and the call proportion is (high-temperature zone: 100%, other temperature zones: 0%). If no, that is, the available heat storage of the high-temperature zone is insufficient to cover the total demand. The heating scheme is that the total available heat storage (100%) of the high-temperature zone is called out first to meet part of the total demand. The remaining demand = heating load demand value - available heat storage of the high-temperature zone. Then, the remaining demand is taken as a new "demand value" to repeat the above judgment and call logic for the next temperature zone (such as the medium-temperature zone). This process is recursively performed until the demand is fully met or all temperature zones have been called and still not enough. If all temperature zones are called and still not enough, a backup scheme is enabled, for example, the power grid power supply module is started, or the heating power set value is reduced according to a preset rule.

[0031] Through the above operation, the embodiment of the present application can generate a specific energy deployment action plan according to the real-time demand of the user end and the heat energy inventory state, thereby completely solving the problem of "blind heat storage and energy supply" in the prior art, and providing a direct decision basis for realizing precise, orderly and efficient heat energy supply.

[0032] Step S110, control the operating parameters of the heating circulation system according to the heating scheme to deliver the heat energy stored in the layered heat storage device to the user end, and dynamically adjust the operating parameters of the heating circulation system based on the temperature feedback information of the user end to maintain the stability of the heating.

[0033] After obtaining the heating scheme, the embodiment of the present application first performs energy extraction and delivery according to the heating scheme: according to the call priority and proportion determined in the scheme, the control instructions for the specific operating parameters of the heating circulation system are converted. The total flow and proportion of hot water extracted from each temperature zone are mainly controlled by adjusting the operating frequency of the variable frequency circulating pump in the heating circulation system, and the related valves (such as the water mixing valve and the three-way valve) are adjusted, so that the hot water of different temperatures extracted from the heat storage device is mixed and delivered to form a total heat output that meets the requirements of the scheme.

[0034] Subsequently, the system enters a feedback-based dynamic adjustment phase: in order to overcome the direct influence of real-time interference such as pipeline loss and environmental changes on the heating effect, the system continuously receives temperature feedback information (such as the actual indoor temperature) from the user end and compares it with the preset target temperature range in real time. When the actual temperature deviates from the target, the system will automatically fine-tune the operating parameters of the heating circulation system (for example, increase the pump frequency to increase the flow rate, or adjust the water mixing ratio to change the water supply temperature) to dynamically compensate and correct the heating output. Through the closed-loop control of "plan execution-effect monitoring-parameter fine-tuning", the intelligent scheduling scheme is finally implemented to achieve stable and comfortable heating effect at the user end, ensuring that the heating quality at the end remains highly stable even in the case of front-end energy fluctuations.

[0035] The embodiment of the present application provides a kind of intelligent high-efficiency heating method of wind and light abandoned, which obtains the electric energy parameter of wind and light abandoned and the heat load demand value of user end in real time, dynamically regulates and controls the number of operation module of modular electric heating device by preset power adaptation strategy, accurately adapts the fluctuation of abandoned power to maximize the consumption of abandoned power;Different temperature circulating water is stored and kept by layered heat storage device, and heat loss is reduced, which provides buffer and adjustment capacity for stable heating;Determine the priority and proportion of heat storage calling based on supply-demand matching strategy, and dynamically adjust the operating parameters of heating circulation system based on user end temperature feedback, effectively solve the technical problems of low abandoned power consumption efficiency, poor heating stability and insufficient supply-demand matching degree in the prior art, realize efficient use of abandoned power, accurate and stable heating and energy optimization, improve heating comfort and energy utilization efficiency.

[0036] In an alternative embodiment, the electric energy parameter includes: abandoned power; Figure 2 As shown in the above step S104, based on the electric energy parameter, the preset power adaptation strategy is called to dynamically control the number of operation modules of the modular electric heating device, which specifically includes the following steps: Step S1041, obtain the preset abandoned power consumption starting threshold and the rated power of a single electric heating module in the modular electric heating device.

[0037] Specifically, the abandoned power consumption starting threshold is a preset power value (for example, 50kW), which defines the minimum power threshold for the system to start actively consuming abandoned wind and light power, to avoid frequent start-stop of equipment causing loss when the abandoned power is too small and does not have economic or technical consumption value. The rated power of a single electric heating module is the design nominal power of each modular heating unit (for example, 50kW), which is the basic unit for module quantity calculation. The acquisition of the above two parameters provides a clear numerical reference for subsequent judgment and calculation, ensuring the orderliness and economy of control actions.

[0038] Step S1042, in the case of determining that the curtailment power is greater than or equal to the curtailment startup threshold, the number of modules currently required to be started by the modular electric heating device is calculated according to the curtailment power and the rated power.

[0039] After obtaining the curtailment startup threshold, the embodiment of the present application compares the real-time monitored curtailment power with the curtailment startup threshold. Only when the curtailment power reaches or exceeds the threshold, the system determines that there is enough curtailment power to be consumed at present, and enters the formal consumption calculation process; otherwise, the system will maintain the heating device in standby or low-power state.

[0040] When the startup condition is met, the following calculation is performed: according to the current curtailment power and the known single-module rated power, the number of electric heating modules required to be put into operation to maximize the consumption of this part of power is calculated. The calculation logic is usually: module number = curtailment power / single-module rated power (the result is rounded down). For example, if the curtailment power is 230kW and the single-module rated power is 50kW, it is calculated that 4 modules need to be started (230 / 50=4.6, rounded down to 4). This calculation method directly realizes the "quantization" of fluctuating curtailment power into discrete and executable device start-stop instructions, which is a specific embodiment of dynamically adapting to power fluctuations.

[0041] Step S1043, a module start-stop control instruction corresponding to the module number is generated and issued to the modular electric heating device.

[0042] According to the number of modules calculated in the previous step, the embodiment of the present application further generates a specific and digital start-stop control instruction. The instruction will specify which electric heating modules need to be started (or which group) and which electric heating modules need to be turned off, to ensure that the total number of modules actually running matches the calculated number of modules.

[0043] Subsequently, the instruction is issued to the electric control unit of the modular electric heating device through the control network (such as industrial bus). The electric control unit receives and executes the instruction, drives the corresponding device to complete the physical start-stop operation of the specific heating module. Through this step, the abstract decision based on power calculation described above is accurately and timely converted into the change of the physical state of the heating device, so as to finally realize the follow-up response to the fluctuation of curtailment power, and convert the fluctuating electric energy into heat energy in real time and in quantity.

[0044] In an alternative embodiment, the layered heat storage device comprises: a high-temperature zone, a medium-temperature zone and a low-temperature zone, and a temperature insulation plate is arranged between each temperature zone to prevent heat exchange; the embodiment of the present application further comprises the following steps: Step S201, calculating the ratio between the curtailment power and the heat load demand value.

[0045] Step S202, performing the priority allocation strategy based on energy sufficiency according to the ratio.

[0046] Wherein, in the case of determining that the ratio is greater than the first proportion threshold, the converted heat energy is controlled to be preferentially stored in the high-temperature zone of the layered heat storage device.

[0047] In the case of determining that the ratio is less than the first proportion threshold and greater than or equal to the second proportion threshold, the converted heat energy is controlled to be used for direct heating to the user side and for heat storage in the medium-temperature zone of the layered heat storage device at the same time.

[0048] In the case of determining that the ratio is less than the second proportion threshold, the stored heat energy in the layered heat storage device is called for heating, and when the called heat energy is insufficient, the power grid is called to supplement the missing heat energy.

[0049] Specifically, the ratio of the curtailed power to the heat load demand value quantifies the sufficiency of the curtailed energy relative to the actual demand at the current time. A ratio greater than 1 indicates that the curtailed power is sufficient, and a ratio less than 1 indicates that the curtailed power is insufficient. By continuously calculating this ratio, the system can convert the complex supply and demand state into a clear and comparable numerical signal, providing a direct basis for subsequent strategy judgment.

[0050] Next, the ratio is compared with the preset proportion threshold (the first proportion threshold and the second proportion threshold, for example, taking values of 1.2 and 0.8 respectively), and according to the comparison result, the preset priority allocation strategy corresponding to different energy sufficiency scenarios is executed, so as to dynamically determine the flow direction (storage or direct supply) of the newly generated heat energy and the storage priority.

[0051] When the system determines that the ratio is greater than the first proportion threshold, it means that the curtailed power is significantly higher than the current heat load demand (for example, the curtailed power is more than 1.2 times the demand). In this sufficiency scenario, the core of the strategy is to preferentially store the converted heat energy in the high-temperature zone of the layered heat storage device. This means that the system will maximize the use of the abundant curtailed power to produce high-quality heat energy and store it, rather than directly use it to meet the current relatively low heat demand. The technical purpose is to establish a high-quality "energy reservoir" when energy is sufficient, store the fluctuating and intermittent curtailed power resources in the form of high-quality heat energy, and provide protection for future energy shortages or high demand. This effectively solves the supply and demand mismatch problem of "insufficient heat storage when curtailed power is sufficient" in the background technology.

[0052] When the system determines that the ratio is less than the first ratio threshold and greater than or equal to the second ratio threshold, it means that the curtailed power and the heat load demand are roughly matched (for example, the curtailed power is between 0.8 to 1.2 times the demand). In this balanced scenario, the strategy is changed to use the converted heat energy for direct heating to the user side and for storing in the medium-temperature zone of the layered heat storage device at the same time. On the one hand, the system uses a part of the heat energy in real time to meet the current demand of the user, realizing immediate consumption; on the other hand, another part of the heat energy (usually the part exceeding the instantaneous demand or the part with optimal utilization efficiency) is stored in the medium-temperature zone as a reserve for smoothing future fluctuations. This strategy takes into account both immediate consumption and buffer reserve, improving the flexibility of system operation, striving to meet the current demand while making moderate reserves for possible future fluctuations.

[0053] When the system determines that the ratio is less than the second ratio threshold, it means that the curtailed power is insufficient to cover the current heat load demand (for example, the curtailed power is less than 80% of the demand). In this shortage scenario, the core of the strategy is to prioritize the use of stored heat energy in the layered heat storage device for heating. The system will call stored heat energy from the high-temperature zone, the medium-temperature zone, etc. according to the heating scheme to make up for the power gap. This strategy ensures that heating is not interrupted when curtailed power is insufficient. Further, as a kind of completeness guarantee, when all stored heat energy is still insufficient, the system will call the power grid to supplement the missing heat energy. This usually means starting the standby electric heater (powered by the power grid) or supplementing heat in other ways, thus constituting a comprehensive, multi-level energy security system from clean curtailed power to heat storage buffer, to stable power grid, ultimately realizing continuous and stable heating, overcoming the defect of "shortage of energy supply during user peak" in the prior art.

[0054] In an optional embodiment, in step S106, the converted heat energy is transferred to the circulating water through the heat exchange medium, which specifically includes the following contents: The heat exchange between the heat exchange medium and the circulating water is realized by a double-pipe heat exchanger, and the heat exchange medium circulates in the inner side of the heat exchanger, and the circulating water circulates in the outer side of the heat exchanger.

[0055] Specifically, the embodiment of the present application adopts a high-efficiency heat exchanger, specifically a double-pipe heat exchanger, as the core equipment for realizing the transfer of heat energy from the intermediate heat exchange medium to the heating circulating water. The structure physically isolates and tightly couples the flow channels of the two fluids (heat exchange medium and circulating water) to achieve efficient heat exchange. Inside the heat exchanger, the heat exchange medium (such as high-temperature heat-conducting oil) circulates in the pipes on the inside of the heat exchanger. This part of the high-heat fluid carries the heat from the electric heater. At the same time, the circulating water of the heating system circulates in the flow channel on the outside of the heat exchanger. The two fluids are arranged in counter-flow or co-flow on both sides of the heat exchanger wall, and conductive heat exchange is carried out through the heat exchanger wall. Such a structure design effectively solves the technical problems that may be caused by direct heating of the circulating water by the electric heater, such as fouling, local overheating, and the influence of water quality on the service life of the heating element, while providing good controllability and heat exchange efficiency.

[0056] In an alternative embodiment, the heat storage state parameters of each temperature zone in the layered heat storage device include the average temperature and available heat storage of hot water in each temperature zone; and the step S108 of determining the heating scheme based on the heat load demand value and the heat storage state parameters of each temperature zone in the layered heat storage device comprises the following steps: According to the preset calling rule, the heat energy is preferentially called from the independent temperature zone with the highest average temperature, and if the available heat storage of the temperature zone is insufficient, the heat energy is sequentially supplemented from other independent temperature zones in order of decreasing average temperature until the total called heat energy meets the heat load demand value, thereby forming the heating scheme.

[0057] Specifically, the supply-demand matching strategy adopted by the embodiment of the present application has a clear, definite and efficient calling rule as its core: when making a decision, the system preferentially calls heat energy from the independent temperature zone with the highest average temperature. This rule directly reflects the principle of preferential use of high-grade heat energy (high-temperature hot water), because using higher-temperature heat energy can reduce the required water flow or more easily maintain the stability of the water supply temperature under the premise of meeting the same heat load demand, thereby improving the overall energy efficiency and heating quality of the system.

[0058] Furthermore, the rule further defines the processing logic when the resources of the preferentially called temperature zone are insufficient: if the available heat storage of the (highest temperature) temperature zone is insufficient to completely meet the current heat load demand value, the system sequentially supplements the heat energy from the independent temperature zone of the next temperature level in order of decreasing average temperature. This process is a cyclic or progressive judgment and calculation process: the system first attempts to use all the available heat storage of the highest temperature zone to meet the demand; if it is insufficient, the difference is used as a new demand target, and the next highest temperature zone is called; this cycle continues until the total heat energy called from each temperature zone reaches or exceeds the heat load demand value. By executing the above rule, the system ultimately forms a heating scheme.

[0059] And, the heating scheme explicitly contains the call priority (i.e. the call order from high to low temperature) and the specific call ratio. The call ratio is calculated according to the actual contribution of the available heat storage of each temperature zone in the progressive call process and the total heat load demand value. For example, if the final call involves high temperature zone and medium temperature zone, the scheme will explicitly record how many percentage of heat is called from the high temperature zone and how many percentage of heat is supplemented from the medium temperature zone. This strategy ensures that at any moment, the system can generate a certain and quantifiable dispatching instruction based on the current inventory, so as to realize "accurate supply-demand matching" and effectively solve the technical problems of low supply-demand matching degree and poor heating stability.

[0060] In an alternative embodiment, in step S110, the operating parameters of the heating circulation system are controlled according to the heating scheme, specifically including the following steps: Step S1101, according to the proportion of the heat storage energy called from each independent temperature zone (such as high temperature zone and medium temperature zone) determined in the heating scheme, the corresponding total circulation water flow is calculated.

[0061] It is known that the heating scheme contains the specific proportion of heat storage energy called from each independent temperature zone (such as high temperature zone and medium temperature zone). Next, this abstract energy allocation ratio needs to be converted into the specific total circulation water flow required to drive heat energy transportation, and its calculation logic is based on the principle of heat balance: the total heat power required to be output by the system (equal to the user heat load demand value) is known, and the hot water called from each temperature zone has different temperatures (the average temperature of each temperature zone is known). In order to mix the hot water of different temperatures to reach the target water supply temperature and output the required total heat, the total mass flow (or volume flow) required to pump these hot water out of the heat storage device must be calculated. Therefore, the system needs to calculate the total circulation water flow set value required to realize the heating scheme according to the call ratio in the heating scheme, the actual water temperature of each temperature zone, and the target water supply temperature, etc. parameters, through the built-in calculation model or formula (prior art), so as to complete the key conversion from energy dispatching plan to water power transportation instruction.

[0062] Step S1102, according to the total circulation water flow, adjust the operating frequency of the variable frequency circulating pump in the heating circulation system to control the circulation water flow through the heating main pipeline.

[0063] After obtaining the total circulating water flow rate set value, the execution link is entered. In the embodiment of the present application, a variable frequency circulating pump is used as a core power and control component. Specifically, the system adjusts the running frequency of the variable frequency circulating pump in the heating circulation system according to the calculated total circulating water flow rate set value. The control principle is that the delivery flow rate of the circulating pump is approximately proportional to the running speed (determined by the motor frequency). By increasing or decreasing the output frequency of the frequency converter, the speed of the water pump can be linearly and continuously adjusted, so as to accurately control the circulating water flow rate flowing through the heating main pipeline, and make it stable around the set value calculated in step S1101.

[0064] In an alternative embodiment, in step S110, the running parameters of the heating circulation system are dynamically adjusted based on the temperature feedback information from the user end, specifically including the following steps: Step S1103, receiving the measured temperature value from the indoor temperature sensor at the user end.

[0065] Step S1104, comparing the measured temperature value with the preset target temperature range.

[0066] Step S1105, when the measured temperature value continuously falls below the lower limit of the target temperature range, increasing the running frequency of the variable frequency circulating pump and / or adjusting the water mixing valve to increase the water supply temperature.

[0067] Step S1106, when the measured temperature value continuously exceeds the upper limit of the target temperature range, decreasing the running frequency of the variable frequency circulating pump and / or adjusting the water mixing valve to decrease the water supply temperature.

[0068] On the basis of executing the heating scheme and delivering heat energy, the embodiment of the present application further introduces a closed-loop feedback mechanism based on the actual feeling of the user end, dynamically fine-tunes the heating process, and ensures the stability and comfort of the final heating effect. This is a key guarantee link for realizing stable heating and improving user experience.

[0069] Specifically, the system continuously collects the measured temperature value representing the final heating effect through the indoor temperature sensor (such as an indoor temperature controller, with an accuracy of ±0.5℃) deployed at the user end. This can more directly and truly reflect the quality of the heating environment actually felt by the user compared with only monitoring the water supply temperature of the main pipeline. Receiving these multi-point temperature data from the user end constitutes the perception basis of closed-loop control, realizes real-time acquisition of the temperature feedback information at the user end, and solves the problem that the control link of the traditional system is disconnected from the user's feeling.

[0070] Next, the received measured temperature value is compared with the preset target temperature range. This target temperature range is a reasonable interval (for example, 18℃~22℃) set in advance according to the heating comfort requirement. The purpose of comparison is to determine whether the current heating output accurately meets the user's demand or whether there is a persistent deviation. This operation is the premise of adjustment decision, which upgrades the control target of the system from simply executing the flow instruction to maintaining the stability of the terminal temperature.

[0071] When the comparison result identifies a persistent deviation, the system automatically performs the corresponding correction action, which is the core embodiment of dynamic adjustment. The specific adjustment logic is as follows: When the measured temperature value is persistently lower than the lower limit of the target temperature range, it indicates that the heating is insufficient. The system will take one or a combination of the following measures to increase the heating output: 1. Increase the operating frequency of the variable frequency circulating pump: by increasing the circulating water flow, more heat is delivered to the user end in unit time; 2. Adjust the mixing valve to increase the water supply temperature: by changing the mixing ratio of high-temperature water supply and low-temperature return water, the water supply temperature entering the user's heat dissipation system is increased, thereby enhancing the heat dissipation intensity.

[0072] When the measured temperature value is persistently higher than the upper limit of the target temperature range, it indicates that the heating is excessive. The system performs the opposite operation: 1. Reduce the operating frequency of the variable frequency circulating pump: reduce the circulating water flow to reduce the heat delivery rate; 2. Adjust the mixing valve to reduce the water supply temperature: reduce the proportion of high-temperature water supply to reduce the water supply temperature entering the user end.

[0073] Through the above-mentioned "perception-judgment-execution" closed-loop process, the system can compensate in real time for the impact of changes in building thermal inertia, extreme weather, user window opening and other unpredictable disturbances in actual operation on indoor temperature. This ultimately ensures that even in the case of unstable front-end heat source due to fluctuating abandoned power, the user's indoor temperature fluctuation can be controlled within a very small range (such as temperature fluctuation ≤±2℃) through terminal feedback adjustment, significantly improving the stability of heating and heating comfort.

The user adaptation assembly is specifically a building heat station plate heat exchanger (heat exchange area 30-80m 2 ), an indoor temperature controller (installed at the user end with an accuracy of ±0.5℃), which can provide real-time feedback on user heat load demand.

[0078] 5. Intelligent monitoring and control module (core control unit): multiple sensors (temperature, pressure, flow, power, liquid level, and leakage sensors) are installed throughout the system to collect data at a frequency of 2s / second, and the controller uses an industrial-grade PLC (Siemens S7-1500) + edge computing module, which has built-in power consumption optimization algorithms, supply-demand matching algorithms, and fault diagnosis algorithms. It also includes a configuration interaction unit, which can optionally use a 15-inch touch screen (resolution 1920x1080) that supports 4G / 5G remote communication, and a mobile phone APP / computer client can be used for real-time monitoring, parameter setting, and remote control. In addition, an emergency control module is configured: an emergency stop button and a remote alarm function (SMS + APP push), which can quickly respond when an abnormality occurs.

[0079] 6. Safety protection module (comprehensive protection), including: electrical protection, heat protection, environmental protection, and fire protection. Among them, the electrical protection includes: a leakage protector (action current ≤30mA), overload protection, over / under voltage protection, and short circuit protection, with a cut-off response time ≤0.05s; the heat protection includes: water tank over-temperature protection (>70℃ automatic stop heating), pipeline overpressure protection (>0.4MPa automatic pressure relief), and dry burning protection (liquid level below the lower limit stop pump); the environmental protection includes: waterproof and dustproof design (protection level IP54), low temperature anti-freezing protection (pipeline temperature <5℃ automatic start heating); the fire protection includes: a smoke alarm installed on the top of the water tank and a dry powder extinguisher to prevent fire risks.

[0080] When implementing the above scheme, the intelligent monitoring and control module (control cabinet size 1000mmx1200mmx1500mm) and the data storage server are installed in the control room, the 15-inch touch screen is embedded on the front of the control cabinet, and the sound and light alarm is installed on the side; the outdoor equipment area is arranged according to the process: abandoned wind and light access cabinet → modular electromagnetic heater → sleeve heat exchanger → vertical heat storage water tank → variable frequency circulating pump set → building heat station.

[0081] The pipeline connection relationship is as follows: the abandoned wind and light access cabinet is connected with the electromagnetic heater through the cable, the heater outlet heat conducting oil pipe is connected with the jacketed heat exchanger, and the heat exchanger circulating water pipe is connected with the top of the heat storage water tank (divided into three paths corresponding to three layers of area); the bottom outlet of the heat storage water tank is connected with the circulating pump set, the pump set outlet is connected with the heat supply main pipeline, and the heat supply main pipeline is divided into each building heat station through the electric three-way regulating valve, and the heat station backwater pipeline returns to the water tank low temperature area inlet, forming a closed loop.

[0082] The leakage protector and overload protection device are integrated in the access cabinet, the pressure relief valve and liquid level sensor are installed in the heat storage water tank, the smoke alarm and fire extinguisher are arranged around the equipment area, and all sensors are connected to the control module through the cable.

[0083] After the system starts, the parameter initialization is completed, and the abandoned power and user load data are synchronously collected; based on the data, the abandoned power consumption optimization strategy is generated, the heating module is dynamically started and stopped to realize power adaptation; the heated hot water is stored in the corresponding area of the water tank according to temperature, avoiding mixing; the heating scheme is determined by supply-demand matching judgment, and the variable frequency circulating pump accurately supplies energy according to user load; the user end room temperature is fed back in real time, and the water supply parameter is dynamically adjusted; the data center collects and analyzes the whole process, optimizes the operation strategy, forms a virtuous cycle of "collection-analysis-control-optimization", and meets the shutdown conditions.

[0084] Among them, before the method starts formal operation, there is an implicit system startup and parameter initialization phase. This phase is not a direct energy conversion or control step, but the basis for intelligent operation. After the system starts, a series of preset operation parameters and control thresholds will be loaded from the storage unit. These parameters include: the target temperature range of each temperature zone of the layered heat storage device (such as high temperature zone target 58-62℃, medium temperature zone 50-55℃, low temperature zone 40-45℃), the user end water supply target temperature (such as 45-50℃), and the safety operation boundary threshold (such as voltage allowable range, system maximum allowable pressure, etc.). These preset values provide a reference value for all real-time comparison, judgment and control actions (such as abandoned power consumption starting threshold, target temperature range), and are the premise for the system to realize intelligentization and operate according to the preset strategy.

[0085] The operation of data statistical analysis and optimization is also included in the embodiment of the present application, and the core thereof is that the system will periodically collect and store historical operation data such as abandoned power consumption rate, heat supply efficiency, energy consumption of each device, and user end temperature stability during long-term operation. Based on these big data, the system can use built-in algorithms or machine learning models to review and self-optimize the operation strategy. For example, the abandoned power consumption starting threshold and the proportion threshold in the power adaptation strategy are automatically analyzed and adjusted, or the calling rules in the supply-demand matching strategy are optimized, or even the user heat load mode is predicted. This enables the system to adapt to long-term factors such as seasonal changes and user habit changes, realize the evolution from operation according to fixed rules to continuous optimization of rules during operation, and continuously improve the overall energy efficiency and economy.

[0086] In addition, when the shutdown condition (end of heating season, system failure, manual instruction) is met, the heating module is stopped first, then the circulating pump frequency is gradually reduced, and finally the valve and power are turned off, and the water tank is maintained in a heat preservation state.

[0087] In summary, the embodiment of the present application has the following advantages over the prior art: first, the abandoned power consumption rate is greatly improved. Through the modular electromagnetic heater and the optimization algorithm, the abandoned wind and light power fluctuation is matched in real time, the consumption rate is greater than or equal to 90%, the clean energy is maximized, and thousands of tons of standard coal equivalent of abandoned energy can be consumed annually; second, the stability and comfort of heat supply are significantly improved. The three-layer partition heat storage + insulation board design, combined with precise temperature control, ensures the stability of heat supply, so that the water temperature fluctuation is less than or equal to ± 2℃, and the user experience is greatly improved; third, the supply-demand matching is more accurate. Based on the real-time linkage of abandoned power parameters and user heat load, the "heat storage-energy supply" precise scheduling is realized, the matching degree is more than 90%, and "heat storage waste" and "energy supply shortage" are avoided; fourth, the energy efficiency is higher. The electromagnetic heater (conversion efficiency greater than or equal to 98%) + high-density insulation layer (heat loss is significantly reduced), which improves the energy utilization efficiency and reduces the heat loss and operating cost; fifth, the intelligence and safety are stronger. The electrical, thermal, and environmental multidimensional protection, combined with remote monitoring and automatic optimization, supports unattended operation and remote control, the safety accident rate is controlled to be less than 0.1%, the operation and maintenance cost is reduced, and it is more suitable for large-scale clean heating projects and meets the current energy transformation needs.
