After the progress information of the load control application form is obtained, the power grid management platform can detect whether a change event associated with the main network load control information is triggered or not according to a preset trigger rule and by combining the real-time obtained progress information of the load control application form.
Specifically, the trigger rule may be a trigger rule based on the main network load control information, the distribution network load control information, or the load control mode information.
For example, when a part of parameters in the main network load control information or the distribution network load control information or the load control manner information satisfies the trigger rule, a change event associated with the main network load control information may be detected to be triggered, and when a part of parameters in the main network load control information or the distribution network load control information or the load control manner information does not satisfy the trigger rule, a change event associated with the main network load control information may be detected to be not triggered.
Furthermore, whether a change operation performed by an operator on the main network load control information is received or not may be detected, and when the change operation performed by the operator on the basis of the schedule information of the load control application form acquired in real time is detected, it may be determined that a change event associated with the main network load control information is triggered, and when the change operation performed by the operator on the basis of the schedule information of the load control application form acquired in real time is not detected, it may be determined that the change event associated with the main network load control information is not triggered.
The change operation may be performed by the staff based on the schedule information of the load control application form acquired in real time, or may be performed by the staff needing to change the main network load control information based on the work demand.
When a trigger change event is detected, the main network management system can acquire change information aiming at the main network load control information, and then can update the main network load control information by adopting the change information, so that the step of issuing the main network load control information to the distribution network management system is executed according to the updated main network load control information.
In practical application, when a currently triggered change event is triggered based on a trigger rule, the power grid management platform may further determine a parameter to be changed in the main grid load control information according to the change rule, and generate change information of the parameter to be changed, and then the main grid management system may obtain the change information, generated by the power grid management platform according to the change rule, for the main grid load control information, and update the parameter in the main grid load control information by using the change information, so as to perform a step of issuing the main grid load control information to the distribution network management system according to the updated main grid load control information.
When the currently triggered change event is triggered by change operation based on workers, the power grid management platform can respond to the change operation of the workers, determine parameters needing to be changed in the main grid load control information, determine change information of the parameters needing to be changed in the main grid load control information in the change operation of the workers, and then the main grid management system can acquire the change information of the parameters needing to be changed in the main grid load control information determined by the power grid management platform from the change operation of the workers, update the parameters in the main grid load control information by adopting the change information, and execute a step of sending the main grid load control information to the distribution network management system according to the updated main grid load control information.
In the specific implementation, because when the cooperative work content is changed, the problem that the communication between the main network and the distribution network staff is not timely occurs, so that the staff still operates according to the unchanged work content, and potential safety hazards exist, the power grid management platform can detect whether a change event is triggered or not, and further can change the cooperative work content between the main network management system and the distribution network management system, namely when the parameters in the main network load control information are changed, the trigger change event is detected, and update is performed on the parameters in the main network load control information by responding to the change operation of the staff, or update is performed on the parameters in the main network load control information by a change rule, so that the updated main network load control information can be sent to the distribution network management system, and the cooperative change of the main network management system and the distribution network management system is completed, therefore, the problem that the main network is not communicated with the working personnel of the distribution network in time is avoided, and the potential safety hazard that the operation is still carried out according to the unchanged working content is reduced.

And 103, the main network management system receives the load control mode information fed back by the power mechanism, acquires distribution network load control information in the distribution network management system, and generates target load control information aiming at the target event according to the main network load control information, the distribution network load control information and the load control mode information.
The target load control information may be linkage control information related to the main network management system, the distribution network management system and the power mechanism, and the target load control information may be used to control the power supply amount of the main network and the distribution network through the main network management system, the distribution network management system and the power mechanism.
After the power mechanism feeds back the load control mode information to the main network management system, the main network management system can receive the load control mode information fed back by the power mechanism and acquire distribution network load control information in the distribution network management system, and then can generate target load control information for a target event according to the main network load control information, the distribution network load control information and the load control mode information.
In practical application, the power mechanism may add the load control mode information to the load control request form in the power grid management platform, so that the main grid management system obtains the load control mode information in the load control request form through the power grid management platform, and completes feedback of the load control mode information, and then the main grid management system may obtain the load control task corresponding to the target event by obtaining the main grid load control information, the distribution network load control information, and the load control mode information in the load control request form in the power grid management platform, and integrating the obtained main grid load control information, the distribution network load control information, and the load control mode information, and may issue the load control task after obtaining the load control task.
Specifically, the load control tasks may include a load control subtask for the main network management system, a load control subtask for the distribution network management system, and a load control subtask for the electric power mechanism, and the load control tasks may be used to trigger operations for controlling the power supply amount in the main network management system, the distribution network management system, and the electric power mechanism.
In an optional embodiment, the specific implementation manner of generating the target load control information for the target event according to the main network load control information, the distribution network load control information, and the load control manner information in step 103 may be:
the main network management system respectively checks parameters of main network load control information, distribution network load control information and load control mode information according to preset checking rules; and when the parameters in the main network load control information, the distribution network load control information and the load control mode information are checked to be correct, the main network management system generates target load control information aiming at the target event according to the main network load control information, the distribution network load control information and the load control mode information.
The checking rule is used for checking parameters in the main network load control information, the distribution network load control information and the load control mode information, and the checking rule is generated based on user requirements.

When it is determined that a parameter in the main network load control information, the distribution network load control information, and the load control manner information is abnormal, the main network management system may determine that the parameter in the main network load control information, the distribution network load control information, and the load control manner information is checked incorrectly, the main network management system may generate a parameter abnormality message, notify a worker of the parameter abnormality message to the main network management system, and further receive a reset operation performed by the worker of the main network management system based on the parameter abnormality message, where the reset operation may be used by the main network management system to re-perform the steps from step 101 to step 103 until each parameter in the main network load control information, the distribution network load control information, and the load control manner information obtained after the re-execution is not abnormal.
