The Influence of Load on Risk-Based Small-Disturbance Security Profile of a Power System
IEEE Transactions on Power Systems, 2018Co-Authors: Kazi N. Hasan, Robin Preece, Jovica V. MilanovicAbstract:This paper establishes a generic severity function that can be used to produce power system Security risk Profiles. It is illustrated by analyzing the impacts of system load attributes on the small-disturbance rotor angle stability of a power system. The load attributes contributing to the oscillatory modes can be considered as inherent uncertain variables within power systems and include load power variations, load composition, and load model parameters. Uncertainty in the renewable power generation is also incorporated in the probabilistic modelling and risk assessment to demonstrate the flexibility of the approach. A novel approach is proposed to select the severity functions to logically represent small-disturbance Security margin. The risk Profile of a power system has been presented considering the probability density functions of power system critical modal damping and a selected set of severity functions. The analysis techniques developed are illustrated with a modified version of the 68-bus NETS-NYPS power system with a high amount of renewable power penetration. The relative importance of the load attributes and the impact of these attributes on stability boundaries have been identified at varying risk levels with respect to their contribution to small-disturbance stability.

An integrated Security framework for open wireless networking architecture
IEEE Wireless Communications, 2007Co-Authors: Jongmin Jeong, Z.j. HaasAbstract:An integrated Security mechanism is one of the key challenges in the open wireless network architecture because of the diversity of the wireless networks in OWA and the unique Security mechanism used in each one of these networks. Because the overall Security of the network is as strong as its weakest component, integration of the overall Security mechanism in OWA is of primary importance. In this article, we comparatively analyze the unique network-centric features and Security mechanisms of various heterogeneous wireless networks that are expected to be part of OWA. Then, after defining the specific integrated network model of OWA, we propose an integrated Security platform based on the Security Profile concept
