"Clean Coal" Claims that Solar can't handle Baseload power demands!

[redpoint5]

That's what I keep saying. Solar isn't a replacement to conventional generation, but in addition to it.

Pretty easy to accommodate a few percent of solar / wind onto the grid, but as that percentage increases, the overall costs begin to skyrocket.

In other words, there isn't even a flat LCOE that can be quoted because it depends on the percentage of the grid comprised of solar and various local conditions.

Solar becomes a liability by 10% as shown by California, the correct number is some where around 5%. Solar is only good for covering the peak day time load.
Wind becomes a liability some where around 20% to 25% and that depends on a lot. Such as how evenly distributed the wind farms are to the loads. Wind could make up 50% of a power grids power with the perfect distribution of loads and wind turbines with reliable wind.
For example in Texas if you find Abilene, draw a line straight north and west, that western block of Texas generates most of their wind power. The problem is getting that power a thousand miles south and several hundred miles east.

RE: My post #111, Scott Adams today proposes V2G without an intervening microgrid. Sometimes he talks like an NPC.

Agreed. What makes V2G viable is the Powerwall or equivalent.

Ultimately, networked microgrids with load balancing.

Electric vehicle, microgrid and solar/wind harvesting form a triumvirate. Similar to Internet being formed as a network of networks, rational power distribution would have dumb pipes connecting intelligent edges.

Yeah, I think distributed power will become the norm. Still going to need some sort of centralized control to disconnect / balance sections of the grid as needed.

Just got to the part about V2G in Scott's talk. Seems like he's got enough basic understanding to have a basically sound prediction of where we're headed.

As I understand it, Software Defined Power (a brainchild of data centers) controls the shift between the three phases to modulate something. IDK They know decentalized distribution.

[Piotrsko]

All i know is that phase angle differences appear as a dead short to the generation facility that isn't exactly in sync

[redpoint5]

My assumption is that "selfish" microgrids are likely to function very well to drive electricity costs down and respond in real time to incentives and disincentives. That said, some sort of centralized control would still be necessary to prevent cascading events.

It might be fine if I've got excess capacity and want to arbitrage it out on the grid, but something has got to make sure all the others responding to market price aren't overloading our local circuits. There has to be oversight of distribution.

The Internet is the first thing that humanity has built that humanity doesn't understand, the largest experiment in anarchy that we have ever had.

I'd add from a certain limited understanding of Space Weather.

Suppose you use radiative panels that beam heat directly to the cold darkness of Outer Space, instead of through a wall? Suppose the panels would be 40% the size of PV panels for powering conventional HVAC?

New AC Tech Sends Heat Into Space & Saves 95% On Cooling Bills!

Runs on water/polyethylene glycol.

I'd want a white cupola with a water tank, that has a Rainbird and can be purged during any wildfire event.

I'm sure some combination of 1970s imagination and 2050s technology will be optimal... until we imagine 1990s with 2070s technology.
