It's not clear to me what exactly happened, and I don't have time right now to inspect the log. Keep in mind that capacity charges are for peak demand contributions over the last 168 timeslots, so if there was a peak 5 days ago and you revoked all your tariffs 4 days ago, you could still be charged.

Does this make sense?

Yes grampajohn, that you say is right, but the strange is that the charges continue in the next weeks.
Distribution transaction charges are 0, but capacitytransaction no.

I have the log open, but it would save me a lot of time if you would tell me where to look. Which CapacityTransaction instances, or which timeslots?

Thanks.

Thanks for the details. I've confirmed the situation by filtering out your CONSUMPTION and PRODUCTION tariff transactions, and I see that there is no consumption or production for your broker after ts 463, which is before the end of the first assessment interval. This is now Issue #882. I have an idea what the problem might be; I'll write a test first to confirm it. If it's what I suspect, it will be a quick fix and a big embarrassment for me. I wrote that code.

John

The problem was more subtle than I expected, but we now have a deployed fix. Games that start after about 25 June 17:30 UTC should contain the fix. Thanks for spotting and analyzing this issue.

Thanks for reporting this problem; I'm sorry this is still happening. I've had no time today, and may not find time tomorrow. But I will definitely look into it as soon as I get a break.

Hi John,

Jun 25, 2016; 11:48am you post:

"The problem was more subtle than I expected, but we now have a deployed fix. Games that start after about 25 June 17:30 UTC should contain the fix. Thanks for spotting and analyzing this issue. "

However the problem continues in the final games.  

The proof is game 2016_finals_12, in which COLDPower makes the decision to revoke all his tariffs just after the first CapacityTransaction charge (a large charge) and for the following weeks a CapacityTransaction charge is imposed too. Notice that the agent does not has customers after it revokes all his tariffs.

We do not understand why a broker pay a CapacityTransaction charge  2,3,4,5 ... weeks after it has no customers.

Thanks in advance

Yes, I see that there is still a problem. I did indeed show that one possible cause of this problem could not happen, and a second could, so I added a test and fixed it. There must be a third possibility that I have not yet tracked down. I apologize for having been completely booked yesterday, and unfortunately I won't have much time to work on this until Monday, unless I can pull together enough material to work on it offline during an overseas flight on Sunday. Please be assured that this is very high on my priority list.

Thanks for your patience.

John

We believe the effects of this problem (Issue #882) can be corrected by ex post analysis. I will look into this early next week, and (assuming it's reliable) we'll adjust the scores on the finals to reflect the correction. We do not want the standings in the finals to be affected by this problem.

Thanks John,

After the tournament all need beers and relax. This tournament has been exhausting for the broker developers and for the game developers.

Good Call, Ansel ;)

l guess the time for a beer has come. I'll open one or two bottles tonight (while being in Marseille, awaiting the hopefully epic match against France), I hope that Toby will enjoy a beer as well ( he is on an outdoor trip in Sweden since the start of the tournament). Thanks all for their efforts to make this an interesting competition again! I hope that John and Wolf will solve the capacity charge issues.

And, Ansel, should you ever be in Germany, let me invite you for a beer, was a pleasure to compete with you and your team (and all others as well!).

All the best for now, Wolfram (Team Maxon)

Hi Wolfram,

We are exhausted, but  happy.  Today we (COLD Team) are celebrating the results of this competition.

All teams fought to the last game. Our congratulations to all, in particular for your team (Team Maxon) the absolute winner of this year. Good job of the game developers and the brokers developers.

and if I'm ever in Germany, be sure we will go by beers.

Was a pleasure participate on this competition.

Thanks to all.
