Description

Technical Field

[0001] This invention relates to the field of industrial energy management technology, specifically to a comprehensive energy and carbon dynamic optimization management system based on multi-dimensional data fusion. Background Technology

[0002] As the global goal of carbon neutrality progresses, industrial production systems are facing the dual pressures of energy structure transformation and carbon emission constraints. Traditional single-energy management models are no longer sufficient to meet the current needs of low-carbon manufacturing. In existing industrial scenarios, energy management systems typically focus on real-time balance of electricity supply and demand and energy efficiency analysis, while carbon management systems often focus on ex-post carbon accounting and quota management. These two systems exhibit inherent heterogeneity in data and a mismatch in time scales. Energy data typically presents as high-frequency power fluctuations, while carbon emission data is often based on static factors or long-term statistical values. This results in a disconnect between energy flow and carbon flow at the physical control level, making it difficult to achieve deep synergistic optimization on the same timeline.

[0003] Furthermore, most existing energy and carbon optimization methods rely on rule-based static scheduling strategies or offline linear programming algorithms. These methods are inadequate in handling high-frequency carbon intensity fluctuations caused by renewable energy grid integration, lacking sufficient dynamic response capabilities. When the proportion of clean energy in the external power grid experiences momentary fluctuations, traditional control logic often struggles to map these fluctuations to the operating conditions of production equipment in real time due to the lack of a unified physical model. Simultaneously, existing optimization models typically employ complex logical constraints to describe the physical characteristics of production equipment. This approach not only increases the computational burden on control algorithms but also distorts the mapping between physical objects and control models, making it difficult for the system to minimize carbon emissions while ensuring production continuity when facing complex source-load fluctuations. Therefore, a comprehensive optimization management solution that can break down energy and carbon data barriers, unify physical and information models, and possess high-frequency dynamic response capabilities is urgently needed. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a comprehensive energy and carbon dynamic optimization management system based on multi-dimensional data fusion. This system solves the problem that existing technologies, due to the heterogeneous fragmentation of energy flow and carbon flow data and the lack of a unified physical mapping model, make it difficult for traditional control methods that rely on static rules or complex logic to achieve real-time dynamic collaborative optimization of high-frequency carbon fluctuations while ensuring production continuity.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a comprehensive energy and carbon dynamic optimization management system based on multi-dimensional data fusion, comprising: The multi-dimensional data sensing module is used to collect available power and carbon emission factors on the source side, and to normalize the collected data to construct a source-side carbon voltage vector. The virtual impedance mapping engine module is used to acquire the operating conditions and material inventory data of the load-side equipment, and reconstruct the operating characteristics of the physical equipment into virtual impedance parameters including virtual resistance, virtual inductance and virtual capacitance. An adaptive topology control module is used to analyze the frequency characteristics of the source-side carbon voltage vector and determine the virtual circuit connection relationship between each device node and the source node based on the frequency characteristics to generate a topology correlation matrix. An impedance matching optimization module is used to construct an objective function based on the source-side carbon voltage vector, the virtual impedance parameters, and the topological correlation matrix, and to calculate the optimal virtual response vector and the target impedance correction amount that optimize the objective function. The execution feedback module is used to convert the optimal virtual response vector into the power setting value and action timing of the physical device, and generate control logic interlocks based on the topological correlation matrix.

[0006] Preferably, the multidimensional data sensing module constructs the source-side carbon voltage vector by: mapping the per-unit value of the available power amplitude on the source side to the real part of a complex vector; mapping the product of the differential value of the carbon emission factor with respect to time and the energy-carbon weighting coefficient to the imaginary part of a complex vector; and, based on the complex number construction rule, linearly superimposing the real part with the imaginary part multiplied by the imaginary unit to generate the source-side carbon voltage vector; the multidimensional data sensing module determines the source-side energy supply status by calculating the phase angle of the source-side carbon voltage vector.

[0007] Preferably, the virtual impedance mapping engine module calculates the virtual impedance parameters in the following ways: The virtual resistance is defined as the ratio of the square of the reference virtual voltage to the minimum power required to sustain the equipment process. The ratio of the physical inertia coefficient to the maximum power ramp rate allowed by the device is defined as the virtual inductance; The difference between the maximum inventory capacity and the current inventory is defined as the virtual capacitance.

[0008] Preferably, the virtual impedance mapping engine module is also used to establish a material energy mutual inductance coupling model between devices. When the inventory of downstream devices is detected to exceed the warning threshold, a virtual mutual inductance coefficient is generated based on the impact rate of the power change of upstream devices on the inventory of downstream devices, and mutual inductance impedance is introduced in the virtual circuit calculation to reduce the current of the upstream device branch.

[0009] Preferably, the adaptive topology control module performs time-frequency transformation analysis on the imaginary part of the source-side carbon voltage vector to obtain the dominant frequency. When the dominant frequency is higher than a preset high-frequency threshold, the device node with virtual inductance is configured as a virtual series connection; when the dominant frequency is lower than a preset low-frequency threshold, the device node with virtual capacitance is configured as a virtual parallel connection.

[0010] Preferably, the objective function constructed by the impedance matching optimization module is specifically a carbon flow transport efficiency objective function, which includes two parts: the first part is used to maximize the directional consistency between the source-side carbon voltage vector and the system's total virtual response current vector, and the second part is used to minimize the magnitude of the sum of the imaginary part of the system's equivalent complex impedance and the imaginary part of the source-side internal impedance.

[0011] Preferably, the impedance matching optimization module introduces a virtual phase-locking constraint when solving for the optimal virtual response vector. The virtual phase-locking constraint requires adjusting the device parameters so that the sum of the inductive reactance generated by all virtual inductors, the sum of the capacitive reactance generated by all virtual capacitors, and the algebraic sum of the imaginary part of the source-side impedance at the dominant frequency point approaches zero.

[0012] Preferably, the method by which the execution feedback module performs physical inverse mapping includes: calculating the physical active power setpoint based on the real part of the product of the conjugate vector of the optimal virtual response vector and the corresponding node virtual voltage; calculating the relative delay in the physical time domain based on the phase angle of the optimal virtual response vector divided by the dominant angular frequency; when the relative delay is positive, the control device starts with a delay; when the relative delay is negative, the control device preloads in advance.

[0013] Preferably, the execution feedback module maps the topology correlation matrix to control logic interlocking in the following ways: mapping the virtual serial relationships defined in the topology correlation matrix to sequential control logic, and connecting the start signal of the downstream device in series with the operating status signal of the upstream device; mapping the virtual parallel relationships defined in the topology correlation matrix to synchronous control logic, and allocating load tasks according to the proportion of the virtual admittance values ​​of each device.

[0014] Preferably, the execution feedback module is also used to monitor the actual operating impedance of the device in real time after the instruction is issued, and only when the percentage deviation between the actual operating impedance and the target impedance value exceeds a preset threshold, the impedance matching optimization module is triggered to recalculate the target impedance correction amount.

[0015] This invention provides a comprehensive energy and carbon dynamic optimization management system based on multi-dimensional data fusion. It has the following beneficial effects: 1. This invention constructs a source-side carbon voltage vector, creatively mapping steady-state energy supply capacity to a complex real part and non-steady-state carbon emission fluctuation trend to a complex imaginary part. This effectively solves the problem of inconsistent dimensions and difficulty in coordinated control of energy and carbon data in traditional systems, and realizes vectorized isomorphism of multi-source heterogeneous data. This enables the system to accurately calculate and optimize energy supply stability and carbon emission fluctuation simultaneously in a unified complex domain mathematical model.

[0016] 2. This invention utilizes virtual impedance mapping technology to equate the operating inertia of physical equipment and material inventory to inductance and capacitance parameters in a virtual circuit, respectively, and constructs a virtual impedance network based on Kirchhoff's laws. The mechanism abandons the traditional complex conditional logic judgment code and utilizes the inherent DC-passing, AC-blocking, or charging and discharging physical characteristics of circuit elements to automatically realize flexible adjustment of the timing of production equipment actions, reducing the complexity of the control algorithm and improving the system's adaptive ability to cope with sudden changes in operating conditions.

[0017] 3. This invention adopts an adaptive topology reconstruction and virtual phase-locking strategy based on carbon frequency characteristics, dynamically switching the virtual series-parallel connection relationship between devices according to the dominant frequency of carbon emission fluctuations; by using inductive reactance to suppress carbon jitter in high-frequency series connection and capacitive reactance to absorb low-carbon energy in low-frequency parallel connection, and combined with phase-time conversion to control device start and stop, it achieves precise timing matching between production load and clean energy fluctuations without changing the hardware facilities, effectively reducing the overall carbon loss in the production process.
