FIG. 28 is a diagram illustrating how the Energy Management System Engine works in conjunction with the other elements of the analytics system to provide indexing of the stability and reliability of an electrical power system, in accordance with one embodiment. Conventional approaches to energy management typically rely on real-time data readings supplied directly from power quality meters and sensors that are interfaced with the components (that comprise an electrical system) to provide a simple live metrics (e.g., voltage, current, frequency, etc.) of how the electrical system is operating. Alternatively, conventional energy management systems may also permit basic historical trending and rudimentary statistical methods to be performed to generate a historical energy profile of how the electrical system has previously operated.
