  31. AMI Definition and Components

  32. Meter Reading has gone through several evolutionary cycles, with AMR more recently giving way to AMI. Manual Meter Reading Electronic Meter Reading (EMR) Off-Site Meter Reading (OMR) Automated Meter Reading (AMR) Advanced Metering Infrastructure (AMI) Gateway/ Home Automation Advanced Metering Infrastructure (AMI) is a term coined to differentiate bidirectional, high functionality technologies from older, automated meter reading (AMR) technologies. According to FERC: Advanced metering is a metering system that records customer consumption [and possibly other parameters] hourly or more frequently and that provides for daily or more frequent transmittal of measurements over a communication network to a central collection point.

  33. Utility Operational Benefits: Improved Outage Detection – smart meters automatically send information when power is removed and restored Improved Meter to Billing Processes – moves from a manual to automated process Faster Customer Inquiry Response Time – enables operators ready access to customer information Fewer Customer Complaints, More Customer Control – provides system operator with near-real time information Customer Service Connection Convenience – can remotely provision service Active Tracking of Inactive Meters and Theft – allows verification that no consumption is measured on inactive locations Customer and Societal Benefits: Lower Energy Bills – by shifting consumption to off-peak periods and by conservation Lower Market Price Benefits – reduces the need to purchase energy at higher spot prices Deferred Generation Construction Costs – energy reduction can help avoid new generation Smart In-home Systems – to provide energy information and consumption feedback Distributed Generation Assets – to measure resources that feed or reduce grid requirements Smart Grid Technologies – provides means to improve the performance and reliability of the grid When utilities explore AMI, they realize that it enables key utility, customer and societal benefits

  38. AMI and Smart Grid

  39. Smart Grid and AMIHow AMI reinforces the seven principal characteristics of the Modern Grid • Motivation and inclusion of the consumer is enabled by AMI technologies that provide the fundamental link between the consumer and the grid. • Generation and storage options distributed at consumer locations can be monitored and controlled through AMI technologies. • Markets are enabled by connecting the consumer to the grid through AMI and permitting them to actively participate, either as load that is directly responsive to price signals, or as part of load resources that can be bid into various types of markets, • AMI smart meters equipped with Power Quality (PQ) monitoring capabilities enable more rapid detection, diagnosis and resolution of PQ problems. • AMI enables a more distributed operating model that reduces the vulnerability of the grid to terrorist attacks. • AMI provides for self healing by helping outage management systems detect and locate failures more quickly and accurately. It can also provide a ubiquitous distributed communications infrastructure having excess capacity that can be used to accelerate the deployment of advanced distribution operations equipment and applications. • AMI data provides the granularity and timeliness of information needed to greatly improve asset management and operations.

  40. Smart Grid and AMIHow AMI relates to the 5 key technology areas of the Modern Grid • Integrated Communications: AMI provides the last and by far the most extensive link between the grid (including the consumer’s load) and the system operator. • Sensing and Measurement: Smart meters extensively measure system conditions (including PQ) down to the consumer level. • Advanced Control Methods: Consumer-side applications process information and initiate control actions locally (sometimes based on real time pricing). Distribution operations centers process AMI information and take control actions at the system and regional level. • Advanced Grid Components: AMI supports the deployment of distributed energy resources and can reduce the communication network costs of deploying pole-top distribution automation components. • Improved Interfaces & Decision Support:: AMI consumer portals, home area networks, and in-home displays provide the human interface and support consumer decision-making. Decision support at distribution operations centers is enabled by the additional information provided by AMI.

  41. Head-End MDUS How SAP supports AMI and Smart Grid

  42. Demand Response and Distributed Energy Resources (DR/DER) are key areas of AMI and Smart Grid intersection • Time-based tariff programs enabled by AMI can help meet customers need for more efficiency • TOU linkage to Thermostat program are an effective means of helping consumers capture economic benefits • In-home display units can help customers better understand the connection between consumption and costs • Metering will be used for Measurement and Verification. • Distributed energy resources can be effectively managed, administered and incorporated into integrated reserve management programs: Metering will provide the requisite monitoring • Energy storage can be effectively dispatched to offset peaks; Metering will be used to capture the net results • Distributed Generation can be viewed, managed and controlled as required; Metering will provide net use calculations

  43. Meters can provide “Last Gasp” messaging that indicates a power failure or restoration conditions; Back office applications can leverage this to supplement other network monitoring functions. Linkage between meter physical and electrical addresses can be used for further circuit failure analsys Power restoration notification and the ability to individually “ping” a meter for status can help ensure full restoration in a given area; This could help eliminate “nested” outage call backs for field crews. ReliabilityAutomated outage and restoration processing at service points is a key function that can augment existing outage management processes.

  44. Distribution Grid ManagementFeeder and Distribution Automation can be enabled through the AMI infrastructure and with selected upgraded meter functionality • Distribution Grid Management • Communication/control of distribution switches • Distribution transformer load management • Utilization of sensors for advanced functions/analysis (fault detectors, equipment/conductor temperatures, etc) • Contingency analysis and overload mitigation • Distribution system voltage management/control • Self Healing System/High Speed Communication for control/protection • High speed communication to support advanced sectionalizing schemes • Sensors and other IED’s are being included as AMI network peripherals • Many DA vendors are beginning to support open standards that are being used for AMI networks • This helps further justify AMI and DA infrastructure investments

  45. Smart Grid and AMI Alignment Asset ManagementImproved equipment health assessment and associated asset management functions • Regular data capture from field assets can be used to drive intelligence-based maintenance programs. • Linking status reports with other key parameters (such as temperature) can now provide additional criteria to be used for field operations • Preventative Maintenance routines can begin to displace more expensive Corrective Maintenance dispatches • Inventory management can be optimized based on more accurate models • Load data can be aggregated to identify key areas of interest • Actual field data from meters can be used to verify load design forecasts and limits • Critical conditions can be addressed prior to failure or overstressed states

  46. Summary

  47. AMI Background Linking AMI, Smart Grid, and SAP • AMI provides the link between the customer and the grid via: • Smart Meters and Home Area Networks • AMI communication network • The AMI communication network can be leveraged to support deployment of sensors and monitoring equipment • The MDUS and SAP are key components that need to be integrated to support the required AMI functionality
