Power Flow Problem - 500MW

More Power receives means you are using more than 500MW in utility 2. Check your demand load. Where is this in Dubai?

This is the kind of solution that requires qualified (via experience) Engineers.

I'd recomend you contact a reputable power generation engineering group.

Black & Veatch, comes to mind, there are others.

Big power needs correct and proper answers! Suggest you check with a qualified firm that works with power distribution as a failure will cost more than an expert does!!!

Two BIG questions here-

First, is Utility No2 being billed for more than 500MW of power? If so, by what authority since they contracted for 500 MW and, apparently, no more.

Second- Who knows that Utility No2 is getting more than 500 MW? How and where is it being measured?

Third (lesser) question- Why is Utility No2 getting all of this excess power? Don't they have enough generation capacity to produce up to 500 MW of their load?

Solution Suggestion- Utility No1 installs a set of diodes and vacuum switches that will activate based on the monitored energy flow to Utility No2. OR finds a way to dedicate the output from enough generators to match the 500 MW contract feed.

Utility 2 cannot receive more power than what is agreed and actually consumes. If the Utility 1 injects more power then the system frequency/voltage shall rise, affecting the power quality. If you worry about this kind of problem a solution would be a monitoring system for power quality, and charge penalties to Utility 1. Another solution would be to use an electronic power converter; with it you can power at what frequency you want, no matter what the Utility 1 sends you. This is a more expensive solution.

Thank you all for useful answers

"Usefull Answers" ? Where?

Normally, when you supply a customer you limit his uptake with some kind of device: Fuses, Circuit breakers, etc..

If the consumer takes more power, his Current intake increases. A limiting device will trip his connection to protect the Utility if this can cause disruption to the utility supplying. Otherwise, a metering device will check the amount consumed and charge accordingly. IF NEEDED, an Agreement can be that Any power take exceeding the 500MW at any time, will be recorded and a penalty charge added.

There are many ways to skin the cat....(?)

I found them all useful and yours too since they were all though provoking and opened up my mind to various possibilities. Not that they answered what I exactly was looking for but nevertheless I appreciate everyone's time and efforts.

Great answer and this is exactly what I was looking for.

I agree- Great info and why I love to visit CR4.
