I. Introduction
THE traditional electrical utility industry is undergoing a major transformation that will enable demand management, reliability gains, resource efficiency, customer participation, and cleaner energy across the electrical grid [1]. This transformation is being facilitated by the development of so-called Smart Grid (SG) applications such as Demand Response Management (DRM), the Supervisory Control and Data Acquisition (SCADA) system, the Advanced Metering Infrastructure (AMI), and emergency response [2].
