Suppose I have my own home-grown generator -- wind, solar, etc -- that I
want to connect to The Grid.
The first problem I see is voltage regulation, shunt current:
To feed the grid, you have to be at some voltage above grid voltage.
How do you dump all your current capacity to grid, without possibly
over-volting the grid locally?
And, if just incrementally above grid voltage, how do dump all your current
capacity to the grid, without having to lose it to a shunt? Does a voltage
regulator solve this, or does it still bleed excess off to shunt -- or to a
Even more of a problem would seem to be phase, discussed in
So connecting to the grid is not a trivial matter, not DIY stuff, it
Unless grid voltage regulators/synchroscopes are standard market items.
How does one do this? Idears? Links? ngs?
All these commercially provided windmill generators must have their own
Mebbe Edison was right: Shoulda stuck with DC?
Also, if what I read recently is correct, it seems that that very
high-voltage long distance transmission is actually more efficient with DC!
And now that there are solid state inverters, a DC-based grid might be
With zillions of DC inputs to a DC grid, all the ripple (inherent in
rotary-type systems), would statistically average out to a fairly straight
line, for even better DC!!
Until recently, poss. even still today, Con Ed in NYC provided high-power
DC, for things like elevators, etc. in some older buildings/locations. Man,
what a spark!
But you never see DC in anything constructed new, after the '60s, poss.
