GB Power System Introduction

The GB power system is changing:• Generation

– Closure of large synchronous generation– Increased non-conventional: wind, PV…

• Network– Heavily constrained boundaries (B6 Scotland-England) – Intra-network HVDC, new HVDC interconnectors– Series Compensation (Fixed & Thyristor-Controlled)

Requirement for enhanced monitoring, to:• Clear the fog: Give operators a more confident picture of the

system operating state and true limits• Give early warning of emerging problems• Aid in event diagnosis & response• Provide study data to improve models & understanding



VISOR Introduction - the project overarching objectives and the consortium

The VISOR project: Jan 2014 – Dec 2017

• Funded through Ofgem’s Network Innovation Competition (NIC)

• Project partners – National Grid, SSE, GE Grid Solutions and the University of Manchester

Objectives

• Create the first integrated GB Wide Area Monitoring System (WAMS) across 3 GB Transmission Owners and System Operator

• Deploy Phasor Measurement Units (PMUs) and the first ever Waveform Measurement Units (WMUs) to provide high resolution, synchronised phasor measurements

• Demonstrate the concepts and tangible benefits of new WAMS capabilities to system planning, real-time operation and post event analysis

Project Key Exploitable Results

VISOR has revolutionised the real-time monitoring of the GB network andimproved the management of the grid integrating new technologies such as • Intra-network HVDC• HVDC interconnectors• Series compensation• Wind farm controllers



Deployment prospects of the most promising solutions

• WAMS Datacentre server at each TOFor local aggregation & visualisation

• WAMS Data Hub at SOFor full GB aggregation & visualisation

• Inter-TO CommunicationsIPSec and MPLS, cybersecurity

• New Waveform Measurement Units (WMUs) deployed for SSO visibility



The main lessons learned and barriers to innovation / Exploitation of the results

Lessons Learnt (+/-) Lesson Learnt Example Positive The importance of a contingency plan Cross- TO communication links

and data transfer.

Positive Ensuring IT/OT cybersecurity personnel are engaged early particularly in pilot projects which can follow ‘unconventional’ routes into the business.

Strict cybersecurity governance protects Energy Management System (EMS)

Positive Importance of internal and external stakeholder engagement.

PG&E and Quanta Technology in particular, USA utilities received $328 million (combined federal and private funding) for PMUs.



Needs for future R&I / Inter-regional cooperation

MIGRATE (Massive InteGRATionof power Electronics)• Look at stability key

performance indicators• Deploying the world’s first live

…

• VISOR used standard protocol IEEE C37.118 for data flows

• Successfully interoperated PMUs of 3 manufacturer with Phasor Data Concentrator (PDC)

• A PDC aggregates multiple PMU streams into a single PDC stream

• Bandwidth efficiency

• Cascading to multiple destinations

• Reliable delivery across long network links (e.g. TCP, data recovery)



VISOR Conclusion

The VISOR project: Jan 2014 – Dec 2017• Successfully created the first integrated GB Wide Area

Monitoring System across 3 GB TOs and SO

• Leading to visibility of sub-synchronous oscillations, and oscillation source location

• Deployed PMUs and the first ever Waveform Measurement Units

• Demonstrated the concepts and tangible benefits of new WAMS capabilities to system planning, real-time operation and post event analysis

• Substantial performance improvement in WAMS performance over the course of the project

• Informed the requirements for a production grade system
