Motivation

• Customer Demand Response Participation
• The value of this mechanism has been summarized
  by the Peak Load Management Alliance as having
  the following impacts on both providers and
  customers/consumers
• Reducing suppliers and customers risk in the
  market
• Reliability of the electricity system
• Reducing costs associated with generation,
  transmission, and distribution
• Creating efficient markets
• Reducing environmental impact by reducing or
  delaying new power plant developments

Smart Grid Definition

• A Smart grid system is any two-way
  communications system and associated equipment
  and software, including equipment installed on
  the electrical delivery system and on the
  premises of retail end-use customers, that
  utilizes the electrical delivery system to
  provide real-time monitoring, diagnostic, and
  control information
• California Senate Bill No. 1438
• Introduced by Senator Padilla on February 21st,
  2008

Smart Grid Network Model

Communication Requirements (ANSI C12.22)

• Initially, communications with electronic devices
  consisted of transporting memory data via
  proprietary protocols which were unique to each
  manufacturer. The desire for interoperability and
  support for multiple manufacturers by reading and
  programming systems created a need for
  standardization of data formats and transport
  protocols.
• This standard extends upon the concepts of the
  ANSI C12.18 Protocol Specification for ANSI Type
  2 Optical Port, ANSI C12.19 Utility Industry
  End Device Data Tables, and ANSI C12.21
  Protocol Specification for Telephone Modem
  Communication standards to allow transport of
  table data over any reliable networking
  communications system.

Components of Smart Grid Distribution System
10
Home Area Network (HAN)

• Each demand response enabled appliance will be a
  hybrid sensor/actuator device
• Each device provides a power measurement to the
  meter
• Meter is an actuator that sends control signals
  to devices based on measurement and pricing
  information provided by utility

11
Home Area Network (HAN)
12
Neighborhood Area Network (NAN)

• From the NAN point of view, each meter is a
  hybrid sensor/actor
• Each access point logically coupled with a local
  control switch for a subset of houses is an actor
• Currently FPL (Florida Power Lighting) has a
  deployment of roughly 5000 AMI smart meters per
  access point
• GE kV2c meter
• Silver Springs NIC equipped with Zigbee Pro
  platform

Conclusion/Looking Forward

• Determine how to anonymize customer data as it
  traverses the NAN
• Incorporate these criteria with the ANSI C12.22
  standard to create a secure HAN and NAN
  communication protocol
