With the diversification and complexity of power demand, demand-side resources, such as controllable loads, distributed power sources, and energy storage systems, have become important factors affecting the accuracy of power grid load forecasting. The characteristics of these resources, such as light intensity, wind speed, real-time electricity prices, load reduction, load transfer, and energy storage charging and discharging power, have brought unprecedented challenges to short-term load forecasting due to their high spatiotemporal variability and uncertainty.

[0028] like Figures 1 to 7 As shown, an embodiment of the present invention provides a power grid load forecasting data collection device, comprising: an installation box 1; a wind speed measurement component 3, comprising a first control box 32, a fan box 33, a wind vane component 37 and a transmission structure, wherein the first control box 32 is rotatably mounted on the top of the installation box 1, the fan box 33 is mounted on the top of the first control box 32, and the wind vane component 37 is rotatably arranged above the fan box 33, and the rotation axis of the wind vane component 37 coincides with the rotation axis of the first control box 32 and the fan box 33; the transmission structure is connected to both the wind vane component 37 and the first control box 32 to drive the first control box 32 to rotate synchronously at the same angle driven by the wind vane component 37; a light collection and measurement component 5, comprising a light intensity detection probe 54, a second control box 53 and a photovoltaic panel 52 for collecting light energy and converting it into electrical energy, the second control box 53 is positionally adjustable mounted on the installation box 1, and the light intensity detection probe 54 is mounted on the second control box 53 to monitor the light intensity in real time through the light intensity detection probe.

[0029] By using the power grid load forecasting data collection device provided in the embodiment of the present invention, through the precise design of the wind speed measurement component 3 and the light collection and measurement component 5, the device of the present invention can collect more comprehensive and accurate environmental data, thereby compensating for the problem in the prior art that the load forecasting accuracy is affected by insufficient environmental monitoring.

[0030] In the above embodiment, the core part of the device is the installation box 1, which has a stable structure and can accommodate and protect the internal components. The top of the installation box 1 is designed with an interface for the wind speed measurement component 3, and the bottom is provided with a retractable mechanism for the light collection and measurement component 5, which ensures that each measurement component can be accurately extended and recovered when needed, while avoiding damage in a non-working state. The core of the wind speed measurement component 3 is the first control box 32, which is connected to the top of the installation box 1 through a bearing and can rotate freely to track the wind direction. The fan box 33 is installed on the top of the first control box 32 and contains a sensitive wind speed sensor. The wind vane component 37 is connected to the first control box 32 through a connecting rod 34, a pulley 35 and a pull rope 36. When the wind direction changes, the rotation of the wind vane component 37 will be transmitted to the first control box 32 through a transmission structure, so that the fan box 33 adjusts the angle to ensure that the measurement direction is consistent with the wind direction, thereby improving the accuracy of wind speed measurement. The second control box 53 is flexibly positioned and connected to the installation box 1 through the translation assembly 4. It can slide along the storage cavity 11 of the installation box 1 to achieve automatic extension and retraction of the light intensity detection probe 54 and the photovoltaic panel 52. The photovoltaic panel 52 is used to collect light energy and convert it into electrical energy to provide energy for the device. The light intensity detection probe 54 is installed on the second control box 53 and is used to monitor the light intensity in real time. Its position and angle can be adjusted to ensure accurate measurement under various lighting conditions.

The wind vane component 37 includes a connecting rod 34, a pulley 35 and a pull rope 36. The wind vane component 37 itself is designed as a light material, which can sensitively respond to changes in wind direction. The connecting rod 34 is connected to the bottom of the wind vane component 37, and the pull rope 36 is fixed on the connecting rod 34, and the other end is connected to the pulley 35 inside the first control box 32. A ring groove 31 is specially designed at the top edge of the first control box 32, and the direction of the ring groove 31 is set around the second control box 53. The pulley 35 is located in the ring groove 31 and can slide freely under the traction of the pull rope 36. When the wind direction changes and the weather vane component 37 rotates, the connecting rod 34 and the pull rope 36 connected thereto will also move accordingly. The pull rope 36 pulls the pulley 35 to slide in the ring groove 31. Since the pulley 35 is connected to the internal mechanical structure of the first control box 32, this sliding will be transmitted to the first control box 32 and the fan box 33 installed on the top thereof through the connecting rod 34 mechanism, so that the first control box 32 and the fan box 33 can adjust the angle synchronously and always keep consistent with the wind direction.

The installation box 1 is the main carrier of the device, and a storage cavity 11 is provided inside. The storage cavity 11 is designed to accommodate and protect the photovoltaic panel 52 and the light intensity detection probe 54. In the non-working state, the photovoltaic panel 52 and the detection probe can be completely stored in the installation box 1 to avoid damage from the external environment, and at the same time facilitate the transportation and storage of the device.

The mounting frame 51 is rotatably connected to the mounting box 1, and the angle can be flexibly adjusted through the drive of the electric push rod 48 to adapt to the changes in the position of the sun at different times and ensure the accuracy of light intensity detection. The moving block 55 is connected to both the second control box 53 and the mounting frame 51. It slides in a straight line in the storage cavity 11 of the mounting box 1 to control the extension or retraction of the light intensity detection probe 54 and the photovoltaic panel 52.

[0033] like Figure 2 , Figure 3 As shown, specifically, the power grid load forecasting data collection device also includes a translation component 4, which is drivingly connected to the moving block 55 and the mounting frame 51 to drive the moving block 55 and the mounting frame 51 to slide along the storage cavity 11 of the mounting box 1. The use of the translation component 4 enables the light collection and measurement component 5 to freely extend and retract in the storage cavity 11 of the mounting box 1, which not only improves the protection of the component, but also enhances the flexibility of data collection. When it is necessary to measure the light intensity, the component can be quickly extended outdoors, and can be recovered in time when it is not in working state or in bad weather, which effectively avoids damage to the component and prolongs its service life.

The translation assembly 4 mainly includes a screw 41, a connecting block 45, a shaft seat 42, a motor 43 and a slider 47, wherein the two ends of the screw 41 are rotatably mounted on both sides of the installation box 1 through the shaft seat 42, the motor 43 is drivingly connected to the screw 41, the screw 41 is driven to rotate by the motor 43, and the connecting block 45 on the screw 41 moves relatively along the axial direction of the screw 41 as the thread rotates.

Through the linkage of the electric push rod 48 and the translation component 4, the flexible adjustment of the angle of the photovoltaic panel 52 is achieved, ensuring that the photovoltaic panel 52 can be automatically aligned according to the change of the light direction, which significantly improves the light energy collection efficiency and the electric energy conversion rate.

[0050] Dynamic scheduling: According to the comparison between power consumption and power generation, the working state of the photovoltaic panel 52 is intelligently scheduled, such as giving priority to turning on the photovoltaic panel 52 for charging when the power is low.

[0051] Energy distribution: The electric energy generated by the photovoltaic panel 52 is reasonably distributed, and the operation of the wind speed measurement component 3 and the light intensity detection component is given priority. The excess electric energy can be stored or used for other auxiliary functions, such as the self-cleaning system.

[0052] Specifically, the installation box 1 has a storage cavity 11 for storing the photovoltaic panel 52 and the light intensity detection probe 54; a brush 12 is fixed on the top inner wall of the outlet end of the storage cavity 11, and the brush 12 contacts the light intensity detection probe 54 and the surface of the photovoltaic panel 52 to remove dust on the upper surface of the light intensity detection probe 54 and the photovoltaic panel 52; the first control box 32 and the second control box 53 are both equipped with built-in batteries, which are connected to the photovoltaic panel 52 to be charged according to the light energy collected by the photovoltaic panel 52; the power grid load prediction data collection device also includes a top plate 38 and a telescopic rod 39, the wind vane component 37 is rotatably mounted on the top plate 38, and the top plate 38 is connected to the installation box 1 through the telescopic rod 39, and the telescopic rod 39 adjusts the height of the top plate 38 by adjusting its length. At least two storage cavities 11 are provided in the installation box 1, which are respectively used to store the photovoltaic panel 52 and the light intensity detection probe 54. A brush 12 is fixed on the inner wall at the top of the outlet end of the storage chamber 11. The brush 12 is in close contact with the light intensity detection probe 54 and the surface of the photovoltaic panel 52. When the light collection and measurement component 5 is extended or recovered from the storage chamber 11, the brush 12 automatically removes dust and impurities on the upper surface of the light intensity detection probe 54 and the photovoltaic panel 52, ensuring the cleanliness of the component surface and improving the light energy collection efficiency and light intensity detection accuracy. Built-in batteries are installed in the first control box 32 and the second control box 53, and the built-in battery and the photovoltaic panel 52 form a closed-loop system for collecting and storing electric energy. When the photovoltaic panel 52 is in working state, the collected light energy will be converted into electric energy, and the built-in battery will be charged to provide a stable power supply for the operation of the device. Under non-light conditions or when the built-in battery is fully charged, the device can automatically stop the electric energy conversion process of the photovoltaic panel 52, reduce energy waste, and realize intelligent energy management. The top plate 38 is designed as a liftable structure, which is connected to the top of the installation box 1 through a telescopic rod 39. The wind vane component 37 is rotatably mounted on the top plate 38 and can rotate freely to indicate the wind direction. The telescopic rod 39 adjusts the height of the top plate 38 by adjusting its length. When the device is not in operation or needs to be stored, the telescopic rod 39 is shortened, the top plate 38 is lowered, and the entire wind speed measurement assembly 3 is stored inside the installation box 1 and protected by the cover frame 2 to avoid damage from the external environment; in the working state, the telescopic rod 39 is extended, the top plate 38 is raised, and the wind vane component 37 can more accurately sense the change of wind direction, thereby improving the accuracy of wind speed measurement.

[0053] The present invention also provides a method for predicting power grid load of demand-side resources, the prediction method comprising the following steps:

[0054] Collecting samples: The collecting devices are arranged in different areas to collect sample sets, where the sample set parameters include weather, day type, historical load and general demand-side resource factors. The general demand-side resource factors include light intensity, wind speed, real-time electricity price, load reduction, load transfer and energy storage charging and discharging power. The wind speed measurement component 3 and the light intensity detection component are used to measure the wind speed and light intensity in different areas of the day and record the data to form a comprehensive sample set;

[0055] Analyze samples: After preprocessing the sample set, divide it into a training sample set and a test sample set; use the training sample set to train the RBM layer by layer, and use the output of the trained previous layer RBM as the input of the next layer RBM, until all RBM layers of the DBN are trained, completing the pre-training of the DBM;

[0056] Establish the model: take the pre-trained DBN as the initial state of the network, and the parameters obtained by training as the initial parameters of the DBN. Then use the back-propagation BP neural network method and the gradient descent method to conduct supervised learning on the overall weight of the network, optimize the initial values ​​of the network parameters of the DBN model, and obtain the optimal load forecasting model.

[0057] Prediction: The trained DBN load forecasting model is tested using the test sample set. The tested model can then predict the load on the forecasting day.

[0058] Furthermore, the characteristic of the cone disk in the step is that the bottom plane radius of the cone disk is the same as the sieve plate. Because the inner circle radius of the water collecting tank is larger than the radius of the filter layer, when the cone disk moves to the inner circle of the water collecting tank, it will not affect the water delivery.

[0059] The present invention can adjust the height of the top plate 38 through the telescopic rod 39. When storing, the height can be lowered to facilitate storage management. The mounting column and the first control box 32 are on the same axis. The wind drives the weather vane component 37 to flutter. According to the position of the tail end of the weather vane component 37, the pull rope 36 pulls the pulley 35 to slide along the annular groove 31, and the connecting rod 34 drives the first control box 32 and the fan blade box 33 to rotate, so that the angle of the fan blade box 33 is consistent with the direction of the wind vane component 37, thereby improving the accuracy of wind speed measurement.

[0060] The present invention drives the screw 41 to rotate through the motor 43, and the connecting block 45 and the screw 41 thread cooperate to drive the connecting block 45 to move horizontally, so that the second control box 53, the light intensity detection probe 54 and the photovoltaic panel 52 are synchronously extended from the storage cavity 11 and maintained in the same straight line. Corresponding to the direction of light, the slider 47 of the electric push rod 48 is pulled by the bottom of the installation frame 51 and slides outward along the moving groove 46 synchronously. When the photovoltaic panel 52 moves out of the installation box 1, the extended end of the electric push rod 48 is retracted to adjust the angle of the photovoltaic panel 52, so as to collect light energy in the direction of light.

[0061] The present invention can store and protect the wind speed measurement component 3 to avoid damage by enclosing the cover frame 2 on the upper end of the installation box 1, and is convenient to carry and transport. After the light energy generated by the photovoltaic panel 52 is converted into electrical energy through the system box 6, the power generation and power consumption are counted, and the wind speed and light intensity values ​​recorded multiple times are recorded through the data transmitted by the first control box 32 and the second control box 53. The brush 12 at the entrance end of the storage cavity 11 can be used to wipe the surface of the photovoltaic panel 52 every time it is retracted and the light intensity is detected, so as to avoid being blocked and covered by dust.

[0062] Compared with the prior art, the present invention can accurately measure the light intensity and wind speed of the outdoor environment through the cooperation of the wind speed measurement component 3, the light collection and measurement component 5 and the translation component 4. The wind speed measurement component 3 can adjust the angle according to the wind direction to avoid errors in the wind speed measurement. The device is easy to carry and install, and is convenient for multi-point distribution in the area to improve the accuracy of the model data in the area.

[0063] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0064] Improve the accuracy of data measurement: The adaptive adjustment module adjusts the position and angle of components in real time according to changes in wind speed and light intensity, ensuring the accuracy of data measurement and improving the reliability of grid load forecasting.

[0065] Automatic cleaning: The innovative brush 12 design automatically removes dust from the surface of the photovoltaic panel 52 and the light intensity detection probe 54, thereby reducing maintenance costs, extending component life, and maintaining consistency and stability in data collection.

[0066] Energy self-sufficiency: The combination of photovoltaic panels 52 and built-in batteries achieves energy self-sufficiency, reduces dependence on traditional power sources, and improves the portability and environmental adaptability of the device.

[0067] Communication and data storage: The communication module enables remote data transmission with the central server, making real-time monitoring and data analysis possible. The storage module ensures the safe storage of data in the event of communication interruption, providing data guarantee for subsequent load forecasting.

[0068] Structural optimization and protection: The telescopic rod 39 is used to adjust the height of the top plate 38 and the detachable cover frame 2 design improves the flexibility and protection performance of the device structure, reduces external interference during wind speed measurement and light collection, and ensures the normal operation of the device in various environments.

[0069] To sum up, the power grid load prediction data collection device of the present invention significantly improves the accuracy and reliability of data collection through its innovative structural design, intelligent control system and self-cleaning mechanism, reduces maintenance costs, extends the service life of the device, and realizes self-sufficiency of energy and remote data transmission and storage, providing an efficient, intelligent and portable data collection solution for power grid load prediction.
