Past wind and solar data to cover some years would then be used to calculate the reliability over some years, toghether with monte carlo analysis of unplanned outages and grid disruptions of various kinds and some reductionist model of how a grid operator would behave and how much spinning reserve they would have.<br /><br />Then they'd be given a score card that contains the cost, the CO2 intensity in grams per kWh supplied(surplus kWh, e.g. wind nobody wants to take delivery of, are simply discarded) and a map containing the extent of brown-outs/rolling black-outs and the extent of black-outs. They'd be given the option to tweak their grid and try again.<br /><br />Unfortunately it's a huge pain in the arse to build such a grid and obtain all the relevant data for some time-period.Soylenthttps://www.blogger.com/profile/08125903130939473555noreply@blogger.comtag:blogger.com,1999:blog-7597656451205429515.post-85712621450610312232010-01-25T01:18:10.895-06:002010-01-25T01:18:10.895-06:00The account of the review process sounds odd.

Do we know in what terms Jacobsen has refused cooperation?<br /><br />If Hannahan has responded to Jacobsen's initial review, and Jacobsen is refusing to exercise his opportunity to comment further, surely that amounts to a decision by Jacobsen to allow the revised version to pass into publication without further comment?<br /><br />The idea that the editor is not able to publish without Jacobsen's say so also seems absurd. Surely in the case of an uncooperative reviewer the editor can exercise discretion. He should publish the revision on the basis that Jacobsen has not felt there is anything further to address in the revision. But failing that, he could assign an alternative reviewer.<br /><br />This just sounds fishy. It doesn't sound like the formal review process is done with yet. I hope Bill will continue to persevere with the editor, or submit to a different journal. It is really important to get these arguments into print. Failing to do so is to abandon the scientific high ground to naive flights of academic fantasy, without challenge from engineering practice and experience.John Morgannoreply@blogger.comtag:blogger.com,1999:blog-7597656451205429515.post-27656509625743177822010-01-24T13:40:51.591-06:002010-01-24T13:40:51.591-06:00Charles,

The AWEA and other wind advocates consistently use a 35% capacity factor in their publications.<br /><br />Can you point me to the references that show US land-based "locations where capacity factors of .40 and above have been observed", because I can't find any. I suspect that some of these observations have been instantaneous or less-than-annual values.<br /><br />Thanks.Paul Lindseynoreply@blogger.comtag:blogger.com,1999:blog-7597656451205429515.post-39479024645326709742010-01-24T13:02:06.569-06:002010-01-24T13:02:06.569-06:00Paul, Archer & Jacobson did not use typical w...Paul, Archer & Jacobson did not use typical wind locations, rather they picked out prime locations in the best settings. There is a very considerable variation in the wind capacity of different locations, and West Texas, Oklahoma, Kansas, and New Mexico have some locations where capacity factors of .40 and above have been observed.Charles Bartonhttps://www.blogger.com/profile/01125297013064527425noreply@blogger.comtag:blogger.com,1999:blog-7597656451205429515.post-42981468295083796572010-01-24T12:24:33.802-06:002010-01-24T12:24:33.802-06:00When I read the Archer & Jacobsen paper, I tho...When I read the Archer & Jacobsen paper, I thought the capacity factor that they used was way too high.
