During my fourth quarter on the E.S. Cornwall Memorial Scholarship (17th August 2015 to 31st October 2015) I have started my placement with Commonwealth Edison (ComEd), the transmission and distribution network owner for northern Illinois.

While at ComEd I will be working with the Smart Grid and Technology team. My work over the past quarter has been focused on developing a modelling algorithm to quantify the ability of ComEd’s distribution network to accommodate distributed generation. This metric, termed “distributed generation hosting capacity”, has been an area of focus for many industry leading research institutions like the Electric Power Research Institute (EPRI). As a part of my work I have combined a number of analysis techniques spanning network modelling, Monte Carlo simulation, and “big data” analysis to develop at technique that can automatically analyse a large number of distribution feeders.

My fourth quarterly report (PDF 3.5MB) provides an overview of this work and its value to the electricity supply industry.

I welcome any feedback on this report or my future direction.

During my third and final quarter with UK Power Networks (1st March 2015 to 31st May 2015) I have undertaken placements with the Network Design Standards team and Future Networks team. My work within these groups have provided me with an understanding of:

  • The Transform model, Element Energy Load Growth model, and Imperial College London Load Related Expenditure model. These models provide UK Power Networks with an understanding of their long-term load growth, estimated customer load profiles, and long-term load driven investment costs.
  • UKPN’s application of the IPEC online partial discharge monitoring tool, which is used in proactively identifying and locating faults on HV switchgear and cables.
  • Undertaking large scale data analysis to assist in understanding and improving network reliability.

My work with the Element Energy Load Growth and Imperial College London Load Related Expenditure model have given me a working experience with these models, while highlighting their importance in understaning and quantifying future network challenges. In contrast my, experience with online partial discharge monitoring has highlighted some of the opportunities and challenges of partial discharge monitoring and its use in managing ageing assets.

My third quarterly report (PDF 1.6MB) provides an overview of this work and the its value to the electricity supply industry.

I welcome any feedback on this report or my future direction.

During the second quarter of my E. S. Cornwall Memorial Scholarship (1st December 2014 to the 28th February 2015) I have continued my placement with UK Power Networks based predominantly in the Engineering Standards and Assurance Team. My work during this period, which was multifaceted, included:

  • Developing an “Asset Management Manual,” which outlines how UK Power Networks manage their assets and how their systems and process are consistent with the requirements of ISO55000. This document will play a key role in UK Power Networks’ transition to and accreditation with ISO55000.
  • Documenting the Distribution Transformer model utilised in the Asset Risk and Prioritisation tool.
  • Undertaking a short placement with the Strategy and Regulation team where I was responsible for analysing and benchmarking DPCR5 and RIIO-ED1 plans across the UK’s 14 distribution license areas.

Through this experience I have continued to learn about optimising expenditure in asset management, particularly through my experience with the Asset Risk and Prioritisation tool. In addition, my experience with the Strategy and Regulation team highlighted the role of the regulator (Ofgem) in incentivising DNOs to improve efficiency and reduce cost.

My second quarterly report (PDF 1.4MB  here) provides an overview of the RIIO model’s output measures and incentives, highlighting challenges they pose for DNOs and how similar mechanisms may be utilised by the Australian Energy Regulator.

It also details my work on the “Asset Management Manual” and Asset Risk and Prioritisation tool.

I welcome any feedback on this report or my future direction.

First report for the E.S. Cornwall Scholarship – 3 months with UK Power Networks

During the first quarter of my E. S. Cornwall Memorial Scholarship (1st September to the 1st December 2014) I began work with UK Power Networks in their Engineering Standards and Assurance Team.

My core focus during this period has been on UK Power Networks’ transition from PAS55 to ISO55000 accreditation. To this end I have:

  • developed an understanding of the integration of PAS55:2008 within UKPN;
  • performed a gap analysis for the transition from PAS55:2008 to ISO55000:2014; and
  • worked with a small team of consultants from The Woodhouse Partnership Limited (TWPL) on the scoping and development of an “Asset Management Manual” for UKPN.

From my review of UK Power Networks’ asset management system I identified a number of innovative projects and systems that are targeted at enabling informed operation and investment in assets. These include:

  • The Distribution Network Visibility (DNV) project, which investigated improvements in monitoring, particularly in secondary substations, and the benefits that may be derived from improved data availability, visibility, and analysis.
  • The Asset Risk and Prioritisation (ARP) tool, an extension of the more widely known Condition Based Risk Management tool, which provides an analytical means for estimating and optimising the replacement and refurbishment of assets based on a variety of asset information.

During this quarter I have sought exposure to these systems and the value they add to asset management.

My work and resultant findings from this period are documented in my first quarterly report (PDF 2.1MB).   I welcome any feedback on this report and my future direction.
