e-News for power industry leaders

Issue 11 - July 2017

Welcome to the eleventh issue of ITL and the new financial year.

As I mentioned in the last edition of ITL, this year is another busy one for CIGRE and its members.

Our SEAPAC event concluded successfully in March with record attendance and we are now looking forward to our other major biennial event - CIDER (Conference on the Integration of Distributed Energy Resources) . This second edition of CIDER has attracted a full exhibition list and major industry support including Siemens as the event Platinum sponsor, Wilson Transformer Company and Schneider Electric - Gold sponsors and PSC, Statcom Solutions and Omicron supporting the event as silver sponsors. We have also been fortunate to have secured Mr. John Bradley - CEO of Energy Networks Australia as the keynote speaker. More information and a registration link to the event which is scheduled for 15th & 16th August can be viewed here.

We have already submitted the abstracts to be considered for the Paris Session in August 2018 and I am please to say we have submitted a record 29 technical abstracts. Thank you to all those who have shown interest and put the work into the submissions and good luck in the selection process.

Membership numbers continue to climb and Australia currently ranks 8th globally in terms of CIGRE equivalent membership.

This edition cover some of the recently published work arising from our members' participation in global working groups and study committees and also offers a summary of the recently concluded symposium in Dublin which dealt with the topic of ‘Experiencing the Future Power System Today’ .

Finally, there is a short section providing a brief summary of upcoming CIGRE related events.

During 2017, we will be making a conscious effort to provide more information on our technical activities via LinkedIn, our website and twitter, so if you want to keep up to date, click below to go to our sites.

CIGRE Reference document demonstrates cables can be used for long AC transmission links

The increasing difficulty with finding overhead line transmission routes and the arrival of large scale wind and solar power stations in new locations is driving a significant interest in the use of long length AC HV and EHV cable systems. Cigre Working Group B1.47, ‘Implementation of Long AC HV and EHV Cable Systems’ has recently published a Technical Brochure (TB 680) as a comprehensive reference document on this topic. The TB demonstrates that it is possible to build AC cable links with lengths of over 150km and loads of more than 500MVA. Ken Barber from Australia chaired the Working Group and the TB is an important document for anyone seriously considering this issue.


Methods recommended for the evaluation of the environmental impact of dispersed generation

Dispersed or Distributed Generation is growing rapidly as a source of electricity. Within Australia, this is almost entirely due to rooftop solar which is approaching 4500MW of capacity. Cigre Working Group C3.05, ‘Environmental Impact of Dispersed Generation’ has recently published a Technical Brochure (TB 679) on recommended procedures and methods for this topic. Steve Martin was the Australian member of the Working Group. The report notes that the the full life cycle impacts including manufacture and disposal should be taken into account in any environmental impact assessment and this should be integrated into an overall system view.


Dublin Symposium - 'Experiencing the Future Power system today'

Some commentators are predicting that within the next 10 or so years, Australia will have one of the highest penetrations of intermittent renewable generation in the world. South Australia already has the second highest per capita penetration of combined wind and solar so this is clearly a possible scenario. The Symposium in Dublin on ‘Experiencing the Future Power System Today’ could therefore not have been timelier. This is particularly so considering the ambitions of Ireland to source 40 percent of its electricity from renewables by 2020 and for wind generation to provide the majority of this. Ireland is a small system with demand varying from 2GW to 7GW and limited support from 1GW of interconnection with Great Britain. It provides a great case study to examine the challenges of a rapid change to the generation mix. A key aspect of the Symposium related to the technical and market impacts of high penetrations of wind and solar. A range of emerging new technologies and methods to manage these challenges were raised in papers and discussed in the various sessions.


Upcoming events and meetings

CIGRE Australia has several upcoming events and meetings that may be of interest.
