AREA OF INTEREST 2: ADVANCED SENSING, MONITORING, AND CONTROL TECHNOLOGIES FOR ENHANCED ASSET UTILIZATION AND GRID RELIABILITY
Area of Interest 2 contains two (2) Subtopics designated as 2A and 2B. The objective of this area of interest is to enhance utilization of available assets and reduce disturbance frequencies and durations. Projects proposed for this Area of Interest will support achieving the Smart Grid 2030 Targets of operational/system efficiency and grid reliability/resilience.

AREA OF INTEREST 2: ADVANCED SENSING, MONITORING, AND CONTROL TECHNOLOGIES FOR ENHANCED ASSET UTILIZATION AND GRID RELIABILITY
Area of Interest 2 contains two (2) Subtopics designated as 2A and 2B. The objective of this area of interest is to enhance utilization of available assets and reduce disturbance frequencies and durations. Projects proposed for this Area of Interest will support achieving the Smart Grid 2030 Targets of operational/system efficiency and grid reliability/resilience.
2A. PROGNOSTIC HEALTH MANAGEMENT (PHM)
PHM technologies are sought to increase the reliability of the grid and the lifetime of the assets themselves. The grid assets in need of PHM include new and legacy equipment critical to ensuring reliable grid operations, such as transformers, switchgear, cables, generators, and motors. PHM technologies shall be capable of monitoring grid assets for signatures of incipient failure, e.g., temperature and pressure (and gradients), dielectric properties of insulating fluids/materials, arcing (signatures and by-products), voltage magnitude, current magnitude, real and reactive power flow direction, and phase angle. PHM technologies should also facilitate use of the sensed information to optimally manage distributed resources and support adaptive protection and control, e.g., by changing the operating points of equipment to extend their life and avoid unplanned outages.

2B. DISTRIBUTION SYSTEM SENSING
Distributed sensors are needed to improve the detection and isolation of system power quality issues, faults, and equipment failure. Phasor measurement units (PMU) already allow for accurate measurement of phase angle, which could be used to prevent unintentional islanding or facilitate grid re-synchronization following an islanding event. However, existing PMUs are mainly intended for transmission level use, and are too costly for widespread deployment in distribution systems. While most electric utilities employ such real-time monitoring of transmission line conditions and major equipment in their substations, very little has been done for monitoring distribution facilities
beyond the substation. Without monitoring capabilities, utilities in general would not have adequate information to respond to, not to mention to prevent occurrence of, any power disturbance events (power outages and power quality phenomena) beyond the substation. The annual cost of such power disturbances to the U.S. economy is enormous – on the order of $100 billion according to EPRI. Additionally, lack of monitoring information would lead to system efficiency loss, as the distribution system performance could not be optimized according to changing conditions.
