By S. Massoud Amin and Anthony M. Giacomoni T THE EXISTING POWER DELIVERY system is vulnerable to both natural disasters and intentional attack. A successful terrorist attempt to disrupt the power delivery system could have adverse effects on national security, the economy, and the lives of every citizen. Secure and reliable operation of the electric system is fundamental to national and intern...

Probably the most significant development in the future is the evolution of the EMS to a more intelligent, automated system to analyze, predict and prevent events leading to a total system collapse. The transition to a highly automated system is possible in part by the recent advances in communication technology, hardware architecture, web services and installation of synchronized phasor measur...

This paper addresses the application of data mining approach on Static Security Evaluation (SSE) of deregulated power system. The process of building binary class classifiers is divided into two components: (i) comparison the methods, and (ii) selection of the best classifier. Preliminary results of using eleven algorithms of Decision Tree’s classifiers (DTC) for SSA are presented. A comprehens...

Dynamic security analysis is performed to ensure that a power system will survive any recognized contingency and will transfer to a new but acceptable steady-state condition. This article deals with one of the very important dynamic security indices – the critical clearing time. Some of the popular methods of calculating the critical clearing time (CCT) have been reviewed. A more recent method ...

This paper proposes a fast pattern matching technique using Artificial Neural Networks that takes advantage of the off-line studies to accurately estimate security limits on-line. The precise methodology of operation planners is followed to establish the limits used to train the networks. A hierarchical design combining margin estimators for different security criteria and operating conditions ...

Increasing the penetration of variable generation has a substantial effect on operational reliability power systems. The higher level uncertainty that stems from this variability makes it more difficult to determine whether given operating condition will be secure or insecure. Data-driven techniques provide promising way identify security rules can embedded in economic dispatch model keep syste...

Optimal power flow (OPF) is a major task in power system economics and operation. In OPF power real power outputs from the generators of a power system are so adjusted that the total production cost is minimum. Security constraint OPF (SC-OPF) is minimizing the cost keeping line flows within their respective limits for security reasons. Real power output from generators, generator bus voltage m...
