1. Role of ICT in Power System

Architecting a packet based network for to support current, developing and future utility use cases and

applicationsAndrew O’Brien, Australia

INDUSTRY DRIVERS AND CHALLENGES

• Major grid transformation with the increased penetration of distributed and renewable energy resources, advanced metering, distributed control and automation, multiservice networks, among others.

• Increase of distributed generation is tending towards a lack of visibility and control at distribution level.

• Communication flow models have largely followed a one-way power delivery flow from generation to consumer.

• Most communication networks consist of multiple point-to-point circuits connecting substations to control centers for SCADA and EMS applications, and point-to-point circuits between substations for protection applications.

THE FUTURE GRIDE WIDE AREA NETWORK

• Electrical grids are shifting to an any-to-any power delivery model.

AN ARCHITECTURAL APPROACH

TELEPROTECTION OVER PACKET NETWORKS

Stringent requirements• Network Latency expected to be 4~16ms• Tolerable jitter depends on the protection relay vendor and

is typically in the range of 0.25 – 1.0 milliseconds• Relay attachment requirements: C37.94, E1/T1, X.21, E&M,

RS422, and recently Ethernet• Transport emulation: CESoPSN, SATOP and EoMPLS.• Frequency synchronisation: Sync-E, 1588 PTP.• Traffic Engineering

EXAMPLES OF EVOLVING REQUIREMENTS

• 61850 Edition 2• Next Generation Energy Management Systems• Wide Area Monitoring, Control and Protection Schemes

NETWORK DESIGN PRINCIPALS

• Determinism• Path selection control• Security• Resiliency• Quality of Service• Traffic Engineering• Ease of Operations• Timing and Synchronisation• Multiple Traffic Type Support

CONCLUSIONS INDIA 2013

• Power industry is seeing a shift in WAN design from TDM to packet based networks

• Utilities have been deploying MPLS and other packet based networks in large scale for some time.

• Successful implementation require careful consideration and planning
