A Novel Power Grid Security Situation Assessment Method for Intelligent Dispatching

To improve the accuracy of power grid security situation assessment and shorten the early warning time of power grid risks, this paper proposes an intelligent scheduling method. Firstly, the dispatching theory is used to process the power grid security data, eliminate the irrelevant attributes of the data, and form a safety data collection. Then, the power grid data is continuously monitored with safety standards, situation thresholds, and safety policies, and the accident assessment and accident location are identified. Finally, refer to the security log and error threshold, determine the security posture level, and send early warning signals. The simulation results show that the intelligent scheduling method proposed in this paper can improve the accuracy of security situation assessment and shorten the early warning time under the guidance of scheduling theory Significantly better than the online monitoring method. Therefore, the intelligent dispatching method can effectively evaluate the security situation of the power grid and meet the requirements of early warning of the security situation of the power grid.
