Re: http://bravenewclimate.files.wordpress.com/2012/02/lang_renewable_energy_australia_cost.pdf Peter, thanks for dropping by. As I emailed you a few days ago (so for the benefit of others) I've had OzEA on life support since July 2011, but hope to have a new academic appointment soon that will ...

Subject: Transmission Analysis
Date: 2012-02-21 (at 04:06:57)

Hi Peter, The easiest thing for me to do would be to send you the 'non-simplified' version of my transmission analysis. This is based on hourly simulation data. Essentially the outcome is that the transmission network is relatively cheap (compared to the ...

Subject: The BoM gridded solar data - Part I
Date: 2012-02-20 (at 17:51:06)

I've been holding the BoM gridded solar 'data' for a few weeks, after Ben Elliston (see above) kindly mailed it to me on a USB stick. First some overall comments, and then more specific ones. Overall the Global Horizontal Irradiance (GHI) ...

Date: 2012-02-18 (at 19:06:39)

Ben McMillan @ #70, you said: "I could do a highly-simplified version of my transmission analysis, with only state-to-state links, and no automatic optimisation of links, if that would be useful. That would be more amenable to producing a bunch of ...

Date: 2012-02-18 (at 19:00:22)

Francis, I just noticed the OzEA round 1 Solar thermal Power Curve" on BNC http://bravenewclimate.com/2012/02/14/grattan-report-2012-critique/ , so I came here looking for more information. Then I found this thread. Comment #69 and #70 are interesting. It is pleasing to ...

Subject: Background Physics
Date: 2012-02-11 (at 07:48:04)

Slugs = Math.ceil(2 * Math.sqrt(EnergyMWh * 3.6e9 * PI / (SlugCForce * Gravity * SlugMass * (SlugLength + SlugSpacing)))); The above line in the code is non-obvious and needs explanation Here is the derivation: V * V = 2 * E / Mass Radius ...

Subject: backgroung physics
Date: 2012-02-09 (at 21:44:59)

Please use "view source" to see the javascript for all the calculations. I tried to calculate everything from first principle. e.g you see the following code. var GravityConstant = 6.67384e-11; var EarthMass = 5.9742e24; var EarthRadius = 6378.1e3; var Gravity = GravityConstant * EarthMass ...

Date: 2012-02-09 (at 18:47:09)

[fc: The form is impressive, but the total lack of background physics etc makes it impossible to take this seriously.] I am not an expert in this area, I merely have a BE (Electrical engineering) and BSc (Mathematics and Computer Science) ...

Subject: some perspective on the extremes
Date: 2012-01-29 (at 23:25:39)

To get some perspective on the extremes in the wholesale market (i.e. ~25% of value in < 1% of time) I've been looking at some artificial scenarios. The aim has been to get a rough handle on the 'value' inherent ...

Have updated the demand data up to end 2011, including the characterisation work. The previously observed growth in the peak demand has not continued in the same fashion.

Date: 2012-01-06 (at 08:33:35)

The cost of the data from the BoM is just to recovery the cost of the portable hard disk they will send it to you on. I've been informed that you are free to take a copy from anyone ...

Subject: BoM Hourly Solar Exposure Gridded Data
Date: 2012-01-05 (at 11:13:16)

Following up on a paper from the AuSES Solar 2011 conference, I have found that BoM are (now) providing hourly gridded irradiance data in 5km cells from 1998 to 2010. See: http://www.bom.gov.au/climate/how/newproducts/IDCJAD0111.shtml Need some dollars to get a copy of this, so ...

Subject: Demand Side Issues
Date: 2011-12-30 (at 14:10:32)

Load shifting and demand side management are potentially an important part of electricity system development, especially in the presence of increasing levels of supply from wind and solar. Back in 2009 when we tried to make sense of what was ...

It's taken me a while Arthur -- thanks very much for your thinking. You say at the end: "5 We will be able to get peoples attention, without spooking them into panic. In which case they will go for the quickest ...

Thanks Mark - I look forward to sitting down and reading this carefully. I noted on first parse that, like the work here, your group is yet to incorporate the transmission. I think this would be really valuable, and still ...

Dear Francis, My email to your University of Adelaide email address bounced, so I'm trying to contact you this way. You may publish this email if you think it appropriate. Congratulations on your simulations, which merit publication in a peer-reviewed journal as ...

Note, NT demand is around 1500 GWh / year. Some details can be found in this Power and Water Corporation presentation [24 Jan 2012] -- note that the above demand, as I understand it, is from the the Darwin- Katherine, Tennant Creek, ...
