Decision tree approach to dynamic security assessment

Dynamic Security Assessment (DSA) of power systems is an important study for real time application in control centers. Historically, various numerical, methods have been adopted for carrying out DSA. These are time consuming and computationally intensive. So faster and easily computable methods for Security Assessment are the need of the hour. With the advances in technology, several new methods which are more effective than the earlier adopted methods have been developed. One of them is the use of Decision Trees (DTs) for Dynamic Security Assessment. The real time system data can be obtained which helps in identifying current system operating condition and hence used it in predicting whether the system is dynamically secure or not.As a result, making accurate predictions for the power system operating conditions is an important task for the current power system research. The research mainly interests in checking if the operating conditions are acceptable after contingencies.
