[0011] According to the above technical solution, the operation method of the power coordination system mainly includes the following steps:

[0012] Step S1: Collect the steam load data, coal input, steam volume and power generation of the equipment through the equipment comprehensive information collection module, and collect the user's usage data and corresponding power consumption data in real time through the user-side comprehensive data collection module;

[0013] Step S2: When data is transmitted in the node, the resource optimization module starts to analyze the server resources occupied by the device and the utilization rate of the resources in the node, and limits the resource occupation of the node according to the remaining resources in the server;

[0014] Step S3: After the data collection is completed, the system starts the power adjustment module, starts to analyze the user's usage habits, predicts the power consumption on the user side according to the analysis results, monitors the actual power consumption on the user side, and adjusts the power distribution according to the actual power consumption;

If the ratio is less than the system threshold, it means that the transmission node does not over-occupy the server resources. Otherwise, the over-occupied server resources of the transmission node are released and returned to the resource pool.

[0019] According to the above technical solution, step S3 further includes the following steps:

[0020] Step S31: retrieve the historical electricity consumption records in the user's electricity meter, identify the user's usage time characteristics and corresponding electricity consumption, cluster according to the user's usage time characteristics, identify all electricity consumption under the current usage time characteristics, and calculate the user's predicted electricity demand under the current usage time characteristics through the formula In the formula, G represents the predicted power demand of the user under the current usage time characteristics, β represents the influence coefficient of the power consumption deviation coefficient of the user under the current usage time characteristics on the predicted power demand, H represents the average power usage of the user under the current usage time characteristics, calculate the sum of the power demand of all users under each time characteristic, and send the total power demand under each time characteristic to the device management end;

[0022] According to the above technical solution, step S4 further includes the following steps:

[0023] Step S41: retrieve the water level change in the equipment water tank, calculate the change in the water in the equipment water tank, that is, the amount of water evaporated, retrieve the rated evaporation capacity of the current equipment, and calculate the steam load rate of the current equipment through the formula In the formula, F represents the steam load rate of the current equipment, L represents the amount of water evaporated in the equipment water tank, and L 定 It represents the rated evaporation capacity of the equipment, and η represents the error coefficient of the steam load rate of the equipment;

When the real-time steam load rate of the device is greater than the second threshold, it is marked as the first adjustment device.

[0026] Step S44: When F2 is less than the threshold set by the system, the tags in other devices are identified. When the first adjustment device exists in the tag, the first adjustment device is called to calculate the adjustable steam volume of the target device, and the adjustable steam volume of the first adjustment device is allocated to the current device to compensate the current device. When the first adjustment device does not exist in the tag, the second adjustment device is called to calculate the adjustable steam volume of the target device, and the adjustable steam volume of the second adjustment device is allocated to the current device. The steam load rate of the current device after adjustment is calculated. If the steam load rate is still less than the system threshold, the steam load rate of the second adjustment device is replaced with the steam load rate of the current device. Otherwise, the adjustable steam volume of the second adjustment device is allocated to the current device.

[0027] According to the above technical solution, step S44 further includes the following steps:

[0030] Compared with the prior art, the beneficial effects achieved by the present invention are as follows: the present invention, by controlling the transmission node to release resources and return to the resource pool when there is no data to transmit, can avoid the transmission node occupying a large amount of server resources, causing insufficient server resources of other data transmission nodes, leading to data transmission congestion and long data transmission time, thereby increasing the data transmission speed and reducing the adjustment delay; by detecting whether the transmission node excessively occupies server resources and releasing the excess resources back to the resource pool, it can avoid the transmission node excessively occupying server resources and causing resource waste, and other transmission nodes cannot obtain sufficient server resources for data transmission, resulting in slow data transmission, further improving resource utilization and data transmission efficiency; by predicting the user's power consumption, the system can adjust the equipment in advance, and can accurately control the amount of coal and power supply invested in the equipment to avoid excessive coal investment. Waste is caused, thereby improving energy utilization efficiency. By dividing the meter changes in the adjacent target areas and dispatching the power plant reserve energy according to the analysis results, it is possible to avoid insufficient electricity supply that causes the company's production equipment to be unable to operate, reduce power fluctuations, improve user experience, and further improve user satisfaction. By real-time detection of the equipment's steam load rate and adjusting the equipment's steam load according to the steam load rate, the equipment's steam loads can compensate for each other, avoiding long-term low steam loads for the equipment, resulting in equipment damage and low efficiency, greatly improving the equipment's utilization rate and equipment efficiency. By analyzing the impact of the equipment's steam load on the equipment's efficiency and then accurately calculating the amount of coal required for the equipment, it is possible to avoid excessive coal filling, resulting in increased power generation, and the enterprises in the park cannot use all the electricity, resulting in a large waste of resources, further improving resource utilization and equipment efficiency.

[0043] Step S2: When data is transmitted in the node, the resource optimization module starts to analyze the server resources occupied by the device and the utilization rate of the resources in the node, and limits the resource occupation of the node according to the remaining resources in the server;

[0046] Step S2 further comprises the following steps:

[0047] Step S21: call the user-side data transmission node, identify whether there is data to be transmitted in the data transmission node, if there is data to be transmitted in the transmission node, mark the node as a running node, otherwise anchor the server resources in the transmission node, release all server resources and return them to the resource pool, inject the data detection resources in the resource pool into the transmission node, and put the transmission node into a standby state. When the data detection resource receives data, wake up the transmission node and call the resources in the resource pool to compensate the transmission node. By controlling the transmission node to release resources and return to the resource pool when there is no data to transmit, it can avoid that the transmission node occupies a large amount of server resources, causing insufficient server resources of other data transmission nodes, resulting in data transmission congestion and long data transmission time, thereby increasing the data transmission speed and reducing the adjustment delay;

By predicting the user's electricity consumption, the system can adjust the equipment in advance, and can accurately control the amount of coal and power supply invested in the equipment, avoid waste caused by excessive coal input, and thus improve energy utilization efficiency;

[0051] Step S32: retrieve the user-side electric meter and identify the voltage in the current line on the user side. When the voltage in the user-side line is less than the threshold set by the system, retrieve the electric meter data of the adjacent target area and identify the real-time change in the electric meter data.

When the first adjustment device exists in the tag, the first adjustment device is called to calculate the adjustable steam volume of the target device, and the adjustable steam volume of the first adjustment device is allocated to the current device to compensate the current device. When the first adjustment device does not exist in the tag, the second adjustment device is called to calculate the adjustable steam volume of the target device, and the adjustable steam volume of the second adjustment device is allocated to the current device.
