Utility owned inverters to come in the future?

Well, I just had to share this article with you, the readers of my blog. And as it turns out I had an invention idea the other week which could allow the power utility to own the inverters.

Now I do not want to give to much information out for my idea; it is safe to say that the utility would also own the inverter with my set up. See, up until now inverters have been owned by the land or business who wanted to feed electricity to the utility. But the idea talked about in this article would allow the power utility to own it instead-- the basic premise to my idea as well.

Now for those of you reading this article who may not have the extensive background in electrical theory and operation, I will try to breakdown a piece of this article for you. See, as an engineer I know that everything dealt with is KVARS not KW (Kilowatts) which you shuld be more familiar with. And a simple graphic representation of KVARS as well as KW and how the relate to each other can be seen in this graphic:


And as can be made very apparent by this graphic-- the cosign theta losses that are incurred in power systems are the resultant vector of both the KVARS and kilowatts. And this vector is referred to as the KVA (Kilovolt-amps) of the system.

And you may be thinking what does this have to do with inverters in the first place? Well if the inverter was utility owned, they could simply change the delay angle, and thereby allowing them to help themselves out by eliminating their KVAR consumption. What would this mean in the end for average customers-- a more reliable grid for sure. But what would this mean for the utility-- a much more efficient means of power transmission, and of course a more reliable grid as an offshoot of this fact.
