Technical Field

[0001] The present invention relates to the technical field of power system optimization dispatching, and in particular to a method, device and computer equipment for managing energy consumption of multi-load equipment. Background Art

[0002] With the widespread application of smart grids and industrial automation, existing load management algorithms usually only target a single device, using simple timing control or direct start-stop methods. Due to the diversity of load devices and their complex energy consumption characteristics, a single scheduling method can no longer cope with the current complex scenario requirements. Especially in scenarios such as industrial parks and smart homes, the energy consumption of various devices changes frequently, and the existing scheduling algorithms lack real-time response and adaptive optimization capabilities, resulting in low overall energy consumption optimization efficiency.

[0003] At present, common dispatching algorithms (such as demand response and load peak shaving) usually focus on a certain goal (such as reducing energy consumption or reducing costs), and fail to strike a balance between energy consumption optimization and operational efficiency. At the same time, traditional centralized dispatching methods are prone to response lags due to the complexity of equipment, which reduces the dispatching efficiency of the system.

[0036] The multi-objective optimization model is expressed by the following formula:

[0037] ;

[0038] in, is the overall optimization goal, , represent the first weight and the second weight respectively.

[0039] In an optional implementation, generating a dynamic power allocation scheme for electric equipment based on a multi-objective optimization model includes:

[0040] Obtain peak electricity price hours and peak load hours;

[0041] Generate a dynamic power allocation plan based on electricity price peak hours, load peak hours and multi-objective optimization functions.

[0042] In an optional implementation, a dynamic power allocation scheme is generated based on the peak electricity price period, the peak load period and a multi-objective optimization function, including:

[0043] During peak electricity price periods, increase the first weight in the multi-objective optimization function , reduce the power output of low-priority equipment and generate an optimized control operation cost plan;

[0066] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0067] According to an embodiment of the present invention, an embodiment of a method for managing energy consumption of multiple load devices is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0068] In this embodiment, a multi-load device energy consumption management method is provided, which can be used in a power system. Figure 1 is a flow chart of a method for managing energy consumption of multiple load devices according to an embodiment of the present invention. Figure 1 As shown, the process includes the following steps:

[0069] Step S101 , obtaining electricity price data and energy consumption data, operating status and load demand of electrical equipment, and classifying the priorities of electrical equipment based on the electricity price data, energy consumption data, operating status and load demand.

[0070] Specifically, in a large industrial park, there are multiple types of electrical equipment. The park's intelligent energy management platform collects real-time power consumption (energy consumption data), operating status, load demand and other data of the electrical equipment through smart meters, sensors and control modules installed on various electrical equipment.

[0071] Electricity price data refers to the tiered electricity price data within a day. Electricity-consuming equipment includes production equipment, air conditioning systems, lighting systems, and charging piles. The priority of electricity-consuming equipment is classified based on electricity price data, energy consumption data, operating status, and load demand. For example:

[0072] Production equipment has high requirements for energy consumption and operational stability and does not allow frequent shutdowns, so it can be defined as the highest priority electrical equipment. The air conditioning system is sensitive to operating time, but the power output can be adjusted dynamically, so it can be defined as a medium priority device. The lighting system and charging pile can flexibly adjust the operating time and power output according to the fluctuation of electricity price data and load conditions, and are flexible to use, so they can be defined as low priority equipment.

[0073] Step S102: using a preset multi-task learning model to predict the load demand of the electrical equipment in a preset time period in the future.

[0074] Specifically, the preset multi-task learning model can use LSTM (Long Short-Term Memory, long short-term memory network), and use LSTM to predict the load demand of the power equipment in the future preset time period. The future preset time period can be set according to actual conditions, and no specific restrictions are made here. In this embodiment, the future preset time period is the next 24 hours.

[0075] Step S103, generating a multi-objective optimization model based on the power consumption equipment priority, load demand and electricity price data, and generating a dynamic power allocation plan for the power consumption equipment based on the multi-objective optimization model.

[0076] Specifically, the multi-objective optimization model in this embodiment includes a load peak target and an operating cost target. Generating a dynamic power allocation plan for electrical equipment based on the multi-objective optimization model refers to controlling the load peak target and optimizing the operating cost target of the electrical equipment to achieve a power allocation plan in a dynamic balance state between the two.

[0077] Step S104, obtaining the load demand and external environment of the electrical equipment in real time, and adjusting the dynamic power allocation scheme of the electrical equipment based on the load demand and external environment.

[0078] Specifically, through closed-loop feedback control, the load demand and external environment of the power equipment are obtained in real time, and the dynamic power allocation plan of the power equipment is continuously optimized through the feedback mechanism, so that the power system is always in the best operating state.

[0079] The multi-load equipment energy consumption management method provided in this embodiment prioritizes the electrical equipment and predicts the load demand, generates a multi-objective optimization model based on the priority, load demand and electricity price data of the electrical equipment, generates a dynamic power allocation plan for the electrical equipment based on the multi-objective optimization model, dynamically adjusts the power allocation to ensure that high-priority equipment is always stably supplied, and low-priority equipment can be flexibly adjusted according to system scheduling. The load demand and external environment of the electrical equipment are obtained in real time through closed-loop feedback control, and the dynamic power allocation plan is continuously optimized through a feedback mechanism, so that the electrical equipment is always in the best operating state, so that energy consumption optimization and operating efficiency are always balanced, thereby solving the problem of failing to strike a balance between energy consumption optimization and operating efficiency.

[0080] In this embodiment, a multi-load device energy consumption management method is provided, which can be used in a power system. Figure 2 is a flow chart of a method for managing energy consumption of multiple load devices according to an embodiment of the present invention. Figure 2 As shown, the process includes the following steps:

[0081] Step S201 , obtaining electricity price data and energy consumption data, operating status and load demand of electrical equipment, and classifying the priorities of electrical equipment based on the electricity price data, energy consumption data, operating status and load demand.

[0082] Specifically, the above step S201 includes:

[0083] Step S2011: Classify the electrical equipment whose energy consumption data and operating status need to be kept stable and whose intermittent shutdown is not allowed as high-priority equipment.

[0084] For example, production equipment has high requirements on energy consumption and operation stability, and frequent shutdowns are not allowed. To ensure the normal operation of production equipment, the production equipment needs to be powered uninterruptedly. Therefore, production equipment can be classified as high-priority equipment.

[0085] Step S2012: Classify the electrical equipment that needs to be operated based on the operating time and whose load demand needs to be dynamically adjusted as medium priority equipment.

[0086] For example, the air conditioning system is sensitive to the operating time, but its power output can be adjusted dynamically. It only needs to ensure that the air conditioning system is powered uninterruptedly during the operating time of the air conditioning system. Therefore, the air conditioning system can be classified as a medium priority device.

[0087] Step S2013: classify the electrical equipment that needs to be dynamically adjusted based on electricity price data fluctuations and load demand as low priority equipment.

[0088] For example, lighting systems and charging piles can flexibly adjust operating hours and power output according to electricity price fluctuations and load conditions. There is no rigid limit on operating hours and they can be flexibly controlled. In order to achieve cost control, they can be used during low-peak electricity price periods. Therefore, lighting systems and charging piles can be classified as low-priority devices.

[0089] Step S202: Use a preset multi-task learning model to predict the load demand of the electrical equipment in a preset time period in the future.

[0090] Specifically, the above step S202 includes:

[0091] Step S2021, obtaining multi-dimensional time series data of electrical equipment, the multi-dimensional time series data including historical load data, historical electricity price data and historical weather data.

[0092] Specifically, historical load data of electric equipment, historical electricity price data, and historical weather data corresponding to the operation period of the electric equipment can be obtained from a database in the power system.

[0093] Step S2022: Use a preset multi-task learning model to extract the time series characteristics of the load change trend of the electrical equipment from the multi-dimensional time series data.

[0094] Specifically, in this embodiment, the preset multi-task learning model adopts LSTM, which includes an input layer, a shared hidden layer and a task-specific output layer. Electricity price data, load demand data, etc. are input into the input layer, and the time series characteristics of the load change trend are extracted in the shared hidden layer, and the load demand for future time periods is independently predicted through the task-specific output layer.

[0095] Step S2023, training the preset multi-task learning model based on the time series characteristics of the load change trend of the electrical equipment, the preset loss function and the preset optimizer to obtain a load forecasting model.

[0096] Specifically, the weighted mean squared error (MSE) is used as the preset loss function to balance the importance of tasks. During the training process, the optimizer is Adam, which is used to accelerate convergence. The specific training process is a mature related technology and will not be repeated here.

[0097] Step S2024: predicting the load demand of the electrical equipment in a preset time period in the future based on the load prediction model.

[0098] Specifically, the current load data of the electrical equipment is obtained, and the current load data of the electrical equipment is input into the load prediction model to obtain the load demand of the electrical equipment in the future preset time period. For example, the load demand prediction results of each electrical equipment are as follows:

[0099] Production equipment: Since its operating time and load are relatively stable, the system predicts that the load will remain at a high level during the daytime in the future working days.

[0100] Air conditioning system: By combining weather forecasts and historical usage data, it is predicted that load will peak during the midday period.

[0101] Charging stations: The power system predicts peak charging demand to be concentrated in the morning and evening. Based on historical usage patterns, the load will be higher in the evening.

[0102] Lighting system: Based on ambient light and historical data, it is predicted that the peak lighting demand in the evening will occur between 18:00 and 21:00.

[0103] Step S203: Generate a multi-objective optimization model based on the power equipment priority, load demand and electricity price data, and generate a dynamic power allocation plan for the power equipment based on the multi-objective optimization model. Figure 1 Step S103 of the illustrated embodiment will not be described in detail here.

[0104] Step S204, acquiring the load demand and external environment of the electrical equipment in real time, and adjusting the dynamic power allocation scheme of the electrical equipment based on the load demand and external environment.

[0105] The multi-load equipment energy consumption management method provided in this embodiment divides the electrical equipment into high-priority equipment, medium-priority equipment and low-priority equipment based on energy consumption data, operating status and load demand. Through the priority classification and real-time monitoring of the electrical equipment, the electrical equipment can be intelligently scheduled according to the actual situation to ensure the normal operation of important electrical equipment. The preset multi-task learning model is used to predict the load demand of the electrical equipment in the future preset time period, thereby realizing the monitoring and prediction of the load status of the electrical equipment and providing conditions for the subsequent dynamic power allocation of the electrical equipment.

[0106] In this embodiment, a multi-load device energy consumption management method is provided, which can be used in a power system. Figure 3 is a flow chart of a method for managing energy consumption of multiple load devices according to an embodiment of the present invention. Figure 3 As shown, the process includes the following steps:

[0107] Step S301, obtain electricity price data and energy consumption data, operating status and load demand of electrical equipment, and classify the priorities of electrical equipment based on electricity price data, energy consumption data, operating status and load demand. Figure 2 Step S201 of the illustrated embodiment will not be described in detail here.

[0108] Step S302: Use a preset multi-task learning model to predict the load demand of the power equipment in a preset time period in the future. Figure 2 Step S202 of the illustrated embodiment will not be described in detail here.

[0109] Step S303: generating a multi-objective optimization model based on the power consumption equipment priority, load demand and electricity price data, and generating a dynamic power allocation plan for the power consumption equipment based on the multi-objective optimization model.

[0110] Specifically, the above step S303 includes:

[0111] Step S3031, obtaining the number of electrical devices.

[0112] For example, in a large industrial park, obtain the number of all electrical equipment in the park, including all production equipment, air-conditioning systems, lighting systems and charging piles.

[0113] Step S3032, determining the cost objective function based on the power consumption equipment priority, load demand, electricity price data and the number of power consumption equipment.

[0114] Specifically, Figure 4 As shown, the cost objective function is expressed by the following formula:

[0115] (1);

[0116] in, is the cost objective function value, The total duration of the optimization time period, such as 24 hours in a day; is the total number of electrical equipment; is the power output of the electrical equipment d at time t, It is a key variable in power system regulation, which determines the power distribution of each power-consuming device at different time points; The electricity price data at time t. The electricity price will fluctuate during the day. For example, the electricity price is higher during the peak period in the evening and lower at night.

[0117] The purpose of the cost objective function is to calculate the total electricity cost. , which can reduce the consumption of expensive electricity and thus reduce operating costs.

[0118] For example, the electricity price is higher between 5pm and 9pm, when the power demand of charging piles and lighting systems is relatively high. The cost objective function value is calculated according to formula (1), and the power output of low-priority equipment is automatically reduced, so that high-priority production equipment can obtain stable power supply first, thereby reducing unnecessary high electricity price expenditures.

[0119] Step S3033, determining the peak objective function based on the load demand and the number of electrical equipment.

[0120] Specifically, Figure 4 As shown, the peak objective function is expressed by the following formula:

[0121] (2);

[0122] in, is the peak objective function value, The goal of formula (2) is to find the maximum value of the total load at each moment, that is, the load peak value; For the calculation of all moments within the optimization period; is the total power output of all electrical devices at time t.

[0123] The peak objective function is used to control the load peak of the entire park to ensure that the total load is not too high and to avoid overloading the power system. The power system keeps the load peak within a reasonable range by reducing the power output of low-priority equipment.

[0124] For example, during the noon period, when the air conditioning system, charging piles, and lighting system are turned on at the same time, the total load may exceed the carrying capacity of the entire park. According to formula (2), the power output of the charging piles and lighting system is automatically reduced to prioritize the stable operation of production equipment and avoid exceeding the load limit of the entire park.

[0125] Step S3034: determine a first weight of the cost objective function and a second weight of the peak objective function based on the electrical equipment priority, load demand and electricity price data.

[0126] Specifically, the first weight of the cost objective function is Indicates that the second weight of the peak objective function is Indicates that the first weight Control the power system's focus on cost targets, the second weight Control the power system's focus on load peak targets.

[0127] In order to optimize the cost target and the load peak target and achieve a balance between the two, the first weight should be adjusted according to the actual situation. and the second weight For example, during peak load periods (such as noon), the system will increase the second weight value, giving priority to optimizing load peaks to prevent overloading of electrical equipment.

[0128] For the first weight and the second weight Dynamic adjustment enables the power system to flexibly respond to different operating conditions and ensure optimal cost control and load management in different time periods.

[0129] Step S3035, generating a multi-objective optimization model based on the first weight, the second weight, the cost objective function and the peak objective function.

[0130] Specifically, the multi-objective optimization model is expressed by the following formula:

[0131] (3);

[0132] in, is the overall optimization goal, and formula (3) represents the overall optimization goal of the power system, combined with the cost objective function and peak objective function , while optimizing operating costs and load peak control. and the second weight Determines the focus of the power system during optimization.

[0133] Step S3036: Generate a dynamic power allocation plan for the electrical equipment based on the multi-objective optimization model.

[0134] In some optional implementations, the above step S3036 includes:

[0135] Step b1, obtaining the peak electricity price period and the peak load period.

[0136] Peak electricity price hours are from 5pm to 9pm every day.

[0137] The peak load period is, for example, 12 noon every day.

[0138] Step b2, generating a dynamic power allocation plan based on the electricity price peak period, load peak period and a multi-objective optimization function.

[0139] In some optional embodiments, step b2 includes:

[0140] Step b21, during the peak electricity price period, increase the first weight in the multi-objective optimization function, reduce the power output of low-priority equipment, and generate an optimized control operation cost plan.

[0141] For example, during peak electricity prices (such as 5pm to 9pm): If set higher, operating costs will be prioritized, reducing electricity bills by reducing the power output of low-priority devices, such as charging stations and lighting systems.

[0142] Step b22, during the load peak period, increase the second weight in the multi-objective optimization function, reduce the power output of medium priority devices and low priority devices and make the high priority devices run stably, and generate an optimized load peak solution.

[0143] For example, during peak load periods (such as noon), the second weight Set it higher to control the load peak and give priority to reducing the medium-priority and low-priority equipment, that is, reduce the power output of the air-conditioning system, lighting system and charging piles to ensure that the total load is within the carrying capacity.

[0144] Step b23, combining the optimization control operation cost scheme and the optimization load peak scheme to form a dynamic power allocation scheme.

[0145] The above steps realize the adaptive distributed dispatching mechanism of the power system, and dynamically allocate the power output of each power-consuming device:

[0146] Power is always allocated to production equipment first to ensure that normal production tasks are not affected.

[0147] The power allocation of the air conditioning system is dynamically adjusted based on the forecast results and actual operation conditions. When the overall load of the park is high (such as during the noon period), the output power of the air conditioning system will be reduced as needed to reduce energy consumption.

[0148] During the peak electricity consumption in the evening, the system prioritizes allocating photovoltaic power to charging piles, reducing the expenditure on purchasing electricity from the power grid.

[0149] The multi-load equipment energy consumption management method provided in this embodiment increases the first weight in the multi-objective optimization function during the peak electricity price period, reduces the power output of low-priority equipment, and generates an optimized control operation cost plan; during the peak load period, increases the second weight in the multi-objective optimization function, reduces the power output of medium-priority equipment and low-priority equipment and enables high-priority equipment to operate stably, generates an optimized load peak plan, and realizes the generation of a dynamic power allocation mechanism based on real-time load feedback, so that the power system has the ability to adaptively adjust to load peaks or electricity price fluctuations.

[0150] Step S304, obtaining the load demand and external environment of the electrical equipment in real time, and adjusting the dynamic power allocation scheme of the electrical equipment based on the load demand and external environment.

[0151] Specifically, the external environment includes weather data and electricity price data, as well as photovoltaic power generation data.

[0152] The above step S304 includes:

[0153] Step S3041, when the actual load of the electrical equipment is higher than the load demand, the load peak optimization scheme is continued to be used by reducing the power output of the medium priority equipment and the low priority equipment and making the high priority equipment run stably.

[0154] Specifically, when the actual load is higher than predicted (for example, a production line suddenly increases its load demand), the power system will ensure the normal operation of production equipment by lowering the output power of medium-priority and low-priority equipment, that is, lowering the output power of the air-conditioning system and lighting system.

[0155] Step S3042: if the photovoltaic power generation in the external environment increases, the photovoltaic power generation is used preferentially to supply power to the electrical equipment, and the operation cost control scheme is adjusted and optimized.

[0156] Specifically, if the amount of photovoltaic power generation increases, the system will prioritize using it to meet the peak load of the park, reducing the amount of electricity purchased from the grid, thereby saving costs.

[0157] The multi-load equipment energy consumption management method provided in this embodiment constructs a multi-objective optimization model through the cost objective function and the peak objective function and the corresponding weights, and generates a dynamic power allocation plan for the power-consuming equipment based on the multi-objective optimization model to ensure that high-priority equipment is always stably supplied and low-priority equipment can be flexibly adjusted according to system scheduling. Through closed-loop feedback control, the power system has the adaptive adjustment capability of the closed-loop feedback mechanism, especially the rapid response and scheduling optimization capability when dealing with sudden load changes.

[0158] As one or more specific application embodiments of the embodiments of the present invention, the multi-load device energy consumption management method provided by the present invention is further described in detail as follows:

[0159] This embodiment focuses on the needs of an industrial park. In a large industrial park, there are multiple types of electrical equipment, including production equipment, air conditioning systems, lighting equipment, and charging piles. Each type of equipment has different energy consumption characteristics, operating requirements, and load changes. In order to maximize energy efficiency and reduce electricity expenses during peak hours, the park adopts the multi-load equipment energy consumption management method of the present invention.

[0160] The core load equipment is as follows:

[0161] Production equipment: Constant operating power of 100 kW, stable operation throughout the day is required.

[0162] Air conditioning system: The power can be flexibly adjusted, ranging from 50-100 kW, and operates from 8:00 to 20:00 daily.

[0163] Lighting system: fixed power 20 kW, lit from 18:00 to 6:00 the next day.

[0164] Charging piles: Maximum load 50 kW, with peak usage between 7:00–9:00 and 17:00–20:00.

[0165] Electricity price difference: During peak hours (17:00–21:00), the electricity fee is 1.5 yuan / kWh, and during other periods, it is 0.8 yuan / kWh.

[0166] The total load limit of the park is set at 200 kW.

[0167] The operation process is as follows:

[0168] 1. Data collection and priority classification: Real-time collection of data such as energy consumption and operating status of equipment in the park, and classification based on importance:

[0169] High priority equipment: production equipment.

[0170] Medium priority equipment: air conditioning systems.

[0171] Low priority equipment: lighting systems and charging stations.

[0172] 2. Load forecast: Combine historical records with real-time status to estimate the load demand in the next 24 hours:

[0173] Production equipment: Stable throughout the day, with a constant load of 100 kW.

[0174] Air conditioning system: peaks at 100 kW at 12:00 and 16:00 respectively.

[0175] Lighting system: Nighttime demand from 18:00 to 21:00 is 20 kW.

[0176] Charging piles: Peak demands in the morning and evening are 30 kW and 50 kW respectively.

[0177] 3. Dynamic scheduling optimization: Use multi-objective algorithms to flexibly adjust equipment power allocation:

[0178] Peak electricity price period (17:00–21:00):

[0179] The production equipment maintains 100 kW.

[0180] The air conditioning system is turned down to 80 kW.

[0181] The lighting system remains at 20 kW.

[0182] The charging stations will be delayed until after 21:00 to avoid peak electricity charges.

[0183] Low electricity price period:

[0184] The air conditioning system was restored to 100 kW.

[0185] The charging station operates at full capacity from 22:00 to 6:00 the next day, with a power of 50 kW.

[0186] 4. Closed-loop feedback and real-time adjustment: The system continuously monitors the actual load and makes dynamic adjustments based on changes:

[0187] If the air conditioning demand increases to 110 kW, the charging pile power will be reduced to 40 kW to ensure that the total load does not exceed 200 kW.

[0188] If the increase in photovoltaic power generation reaches 30 kW, it will be supplied to air-conditioning systems and charging piles first, reducing dependence on the external power grid.

[0189] Implementation results:

[0190] Cost reduction: By adjusting the operating hours of charging piles, electricity bills can be saved by about 300 yuan per day.

[0191] Load peak control: The maximum load was successfully controlled below 200 kW, effectively preventing system overload.

[0192] The multi-load equipment energy consumption management method provided in this embodiment has a dynamic power allocation function. It dynamically adjusts the power allocation according to the real-time load demand and priority of the equipment to ensure that high-priority equipment is always stably supplied, and low-priority equipment can be flexibly adjusted according to the power system scheduling. Through closed-loop feedback control, the energy consumption data and load demand of electrical equipment are collected in real time, and the scheduling decisions are continuously optimized through the feedback mechanism, so that the power system is always in the best operating state. The dynamic power allocation mechanism of this embodiment can be applied to multi-load equipment systems, such as charging pile management, electrical appliance scheduling in smart homes, and other scenarios to ensure the optimal energy efficiency of the overall system.
