[0078] In the embodiment of the present application, the energy analysis and evaluation module analyzes and determines the conversion power value per unit time in the parameter data of each power generation model as follows:

[0079] The historical hydroelectric power generation data is extracted to determine the power generation efficiency of the hydroelectric power generation model, and a hydroelectric power generation mapping table is formed to reflect the conversion power value under the corresponding flow speed within the cycle time T as A a , and the consumption cost corresponding to the cycle time T is N a .

[0080] The historical wind power generation data is extracted to determine the power generation efficiency of the wind energy power generation model, and a wind power generation mapping table is formed to reflect the conversion power value under the corresponding wind speed within the cycle time T as B b , and the consumption cost corresponding to the cycle time T is N b .

[0081] The historical solar power generation data is extracted to determine the power generation efficiency of the solar energy power generation model, and a solar power generation mapping table is formed to reflect the conversion power value under the corresponding light intensity within the cycle time T as D d , and the consumption cost corresponding to the cycle time T is N d .

[0082] The historical biomass combustion power generation data is extracted to determine the power generation efficiency of the biomass energy power generation model, and a biomass energy mapping table is formed to reflect the conversion power value under the corresponding combustion of different biomass materials within the cycle time T as E e , and the consumption cost corresponding to the cycle time T is N e .

[0083] The historical geothermal energy power generation data is extracted to determine the power generation efficiency of the geothermal energy power generation model, and a geothermal energy mapping table is formed to reflect the conversion power value under the corresponding flow within the cycle time T as F f , and the consumption cost corresponding to the cycle time T is N f .

[0084] By establishing each power generation model based on renewable energy power generation data and correlating each power generation model, the power generation values and consumption costs in each energy data are compared and determined, so as to monitor the running state of the system in real time, monitor the fluctuation of wind and solar power generation in real time, so as to realize higher management and evaluation in the subsequent energy selection process, guarantee the accuracy of data, and facilitate better adaptation to strategy scheduling operation.

[0085] In this embodiment of the invention, the effect of wind speed direction change on power generation efficiency is as follows:

[0086] During the process of acquiring wind speed data, the direction data of the wind force is determined simultaneously, so that the power generation efficiency is highest when the blades are facing the wind.

[0087] Starting from the center of the wind turbine, a spatial coordinate system is established to determine the wind direction. The direction of the support frame used for the wind turbine is taken as the opposite direction of the Y-axis. An X-axis is established in the plane where the blades are located, which is perpendicular to the Y-axis from the starting point. A Z-axis is also established in the plane where the starting point is located, which is perpendicular to both the X-axis and the Y-axis.

[0088] The angle between the wind direction and its projection onto the planes along the Y and Z axes is determined by the sensor as α, while the angle between the projection and the Z-axis is β. The measured wind speed is V. c ;

[0089] Based on the determined wind direction, the manufacturer issues adjustment instructions for the wind turbine unit, adjusting the rotor direction angle β of the wind turbine unit to a position perpendicular to the projected lines. At this point, the wind speed directly opposite the blades is V. b =V c ×Cosα,V b This represents the b-th actual wind speed value.

[0090] In this embodiment of the invention, the effect of changes in the illuminated area of ​​a photovoltaic array on power generation efficiency is described:

[0091] Extract the illuminated area S of the photovoltaic array under the same light intensity from historical data. m And the corresponding illuminated area S m The power generation is K m ;

[0092] Therefore, the power generation conversion coefficient for the corresponding area is determined as k = (K1 / S1 + K2 / S2 + ... + K m / S m ) / m, and then determine the real-time power conversion value of solar power generation based on the conversion coefficient k.

[0093] In this embodiment of the invention, the operation of the energy analysis and assessment module in integrating meteorological data, geographical data, and load data to assess and calculate energy usage within a given period is as follows:

[0094] Based on historical load data, the daily load is divided into periodic intervals to determine low load and high load intervals.

[0095] The priority order of each power generation model is determined by determining the corresponding power generation and consumption cost of each power generation model, and then determining the influence degree of each power generation model by combining the change of meteorological data, and finally determining the loss cost of each power generation model during scheduling by the required load position, so as to evaluate the priority of each power generation model.

[0096] In the embodiment of the application, the determination of the priority order of each power generation model is as follows:

[0097] A period interval is selected, and the effective income of each model during the normal operation of the period time is calculated. The effective income calculation formula of hydraulic power generation in the corresponding period time T is: a =A a ×Q1-N a , P a represents the effective income under the current hydraulic conversion power value, Q1 is the value of power conversion, and the effective income P b of wind power generation, the effective income P d of light energy power generation, the effective income P e of biomass power generation and the effective income P f of geothermal power generation are obtained in the same way. Whether all energy models exist in the current energy management area is determined, and after removing the energy models not in the range, the effective incomes of the remaining energy models are compared and sorted.

[0098] Then, it is determined whether the power conversion operation of each energy model is affected under the corresponding different interval nodes through the real-time change of meteorological data, and the effective income of each energy model is sorted after the compensation of the combined meteorological data.

[0099] Finally, the loss of each energy model during power transmission is determined by the scheduling position of the load supply, and the current energy model loss cost and the subsequent energy model saving cost are determined according to the association of the energy model priority order and the load data. The saving cost is the difference between the effective income of the current energy model and the effective income of the subsequent adjacent energy model in the same time supply minus the loss cost. If the loss cost is greater than the saving cost and less than the grid cost, the energy model with the minimum saving cost is selected as the first power supply energy model.

[0100] The sorting of the power supply energy model is realized in sequence, and the power supply strategy is generated.

[0101] By determining the corresponding power generation and consumption costs of each power generation model, the priority of each power generation model is determined. Then, by combining changes in meteorological data, the degree of impact on each power generation model is determined. Finally, the loss cost of scheduling each power generation model is determined by the required load location. In this way, the priority of each power generation model is evaluated and the plan is dynamically adjusted according to the actual situation to ensure the stable operation of the system and the efficient use of energy, while reducing cost losses.

[0102] In this embodiment of the invention, the energy optimization and scheduling module performs energy optimization management operations based on optimization strategies as follows:

[0103] After determining the order of the corresponding power supply energy, the combined power supply operation of the load area is realized according to the order, and when the preceding power supply energy is insufficient to support the load, the subsequent power supply energy is used to combine the power supply.

[0104] Ultimately, when all available power sources are unable to meet the load, direct power supply is achieved through the power grid.

[0105] Example 2 differs from Example 1 in that: the present invention also discloses a comprehensive energy management method, specifically including the following steps:

[0106] S1. Collect and preprocess data on various renewable energy power generation through various sensors;

[0107] S2. Establish various energy generation models and determine the power supply cost of each energy generation model based on power conversion, environmental impact, transmission loss and load data, and determine the optimization strategy for the current period.

[0108] S3. Finally, after generating instructions based on the optimization strategy, the scheduling and management of energy are completed.

[0109] Example 3 differs from Examples 1 and 2 in that: An experimental operation was conducted on a designated small area using an existing energy management system that ranks power supply according to energy conversion efficiency and an energy management system that uses various models to correlate power supply and considers factors based on power supply changes. The load time period and specific conditions of the small area were kept consistent. The final comprehensive energy conversion benefits and any abnormal power supply situations were then recorded. The specific results are shown in Table 1.

[0110] Table 1. Comparison of Experiments

[0111]

[0112] The results show that the existing energy management system needs to participate in power supply through the power grid in the process of energy power supply, so the final comprehensive benefit is lower than that of the energy management system of the application, and the existing energy management system is obviously frequent in abnormal times of not timely in realizing power supply scheduling operation due to environmental fluctuations, so compared with the energy management system of the application, the energy management system of the application can better realize the application in actual operation.
