We express our appreciation to EPRI and in particular Paul Myrda for his support and guidance for the project. We also express our appreciation for the support provided by PSERC's industrial members, as well as EPRI members, and by the Energy management systems (EMS), control centers that manage the transmission-generation grid, have existed since the 1960s. They have gradually evolved over the years mostly in an incremental manner. Now, major transformation is of EMS systems is essential to support emerging behavior the power system, affected by variable and less predictable renewable energy penetration, availability of newer types of sensors, and communication systems, and powerful computation platforms. As part of this project, various " seams " have been identified that are of interest and that are apparent in current power system operations and control practices. These seams are: 1. Communication architecture of current systems is not suitable for enhanced sensing capability enabled by synchronized phasor measurement units (PMU) 2. The difficulty in comparing application results due to the utilization of different models in operations and planning, and to tie these models to PMU data 3. Repetitiveness of simulations in contingency analysis applications 4. Continued utilization of legacy code in today's software applications, which rely primarily on sequential computing rather than taking advantage of modern high performance computing technology 5. A lack of look-ahead visualization capabilities, which are critical for today's modern electric grid with its non-dispatchable renewables, increasing levels of demand response, and deployment of energy storage. There exists a need for next generation power system management tools that use unified geo-spatial models, more efficiently handle massive scenario evaluation such as contingency analysis, and provide look-ahead visualization capabilities. This report focuses on attempting to address some of these limitations. Chapter II of this report provides a summary of advances in fast communication systems for PMU applications, …
