Friday, 18th February, 2022 – A Virtual Conference

The VCE Physics Teachers’ Conference in 2022 jointly organised by STAV and Vicphysics, will take place on Friday 18 February 2022 and, following on from the success of this year’s Conference, it will be a virtual conference.  There will be synchronous (live) and asynchronous (pre-recorded) sessions.

The program is available at this website or downloaded from here. Registration will be available by Friday, 10th December.
The program includes:

  • Keynote address: See details below
  • Three sessions of live workshops, each with six workshops on offer
  • Seven asynchronous sessions which will be available to be viewed from 11th February.
  • VCAA Update and Unpacking assessment in the new VCE Physics Study Design with Maria James, Science Curriculum Manager at VCAA
  • Review of the 2021 VCE Physics Examination by Andrew Hansen, Chief Assessor. A summary of the report will be available on video prior to the conference for teachers to view and forward questions which will be addressed on the day by Andrew.

If you have any questions, please email the STAV Administration Officer

Keynote address – Innovations in electricity: Is 100% renewable now possible?

Speaker: Dr Bob Sheehy, Regenersys P/L
Abstract:

Bob SheehyGeneration of electrical energy has traditionally used coupled thermal engines and very large magnetic rotating generators to convert rotational energy to electricity. The recent explosive growth of power electronics capabilities and energy harvesting devices such as photovoltaic panels, wind turbines, wave and tidal power generators and fuel cells is increasing the amount of distributed electricity sources being connected to our electricity grids. Many of these sources are direct current (DC) in nature and require some form of power conversion to match the alternating current (AC) and frequency of the grid before power can be delivered. Power electronics and advanced software algorithms make it possible for all these renewable sources to emulate traditional rotating generators. Concerns have been raised over the frequency and voltage stability of the grid as more distributed sources are added, but the flexibility of the new power converters and energy storage solutions have already demonstrated that those concerns can be addressed through innovative use of the new technologies.
This presentation will look at the core differences between traditional large thermal power generation and smaller distributed power generation, the inverters and power converters role in interfacing renewable sources to the grid, and how energy storage coupled with power electronics is providing voltage and frequency stabilisation to the grid – unlocking a pathway toward potentially 100% sustainable electricity.

Bio:

Dr Sheehy has a PhD in electrical engineering. He started at CSIRO Division of Applied Physics working in the High Voltage test laboratory on various metrology projects and industrial calibration testing up to 1MVDC and 500kVAC while researching insulation condition monitoring in high voltage motors and generators. He worked in industry where he developed several modular power conversion systems for interfacing batteries with the grid and renewable sources that were licensed for manufacture globally. In the last decade, he has been involved in several teams developing medical products, especially the use of nanotechnology in diagnostic x-ray; development of algorithms for optimised control of micro wind turbines, and development of miniature modular high voltage sources to 160kVDC.
Dr Sheehy has completed two years of Antarctic service as an electrical engineer at Davis and Mawson stations to upgrade and operate scientific instruments used to gather data for climate change analysis, and to support improvements to the station isolated power grids. He is a co-inventor on several pat ents on power conversion, nanotechnology based x-ray tubes and x-ray applications.

This conference is joint initiative of Vicphysics Teachers’ Network and the Science Teachers’ Association of Victoria (STAV).
