If you're describing nearly free and unlimited electricity as a problem, you may want to reconsider some things.
It's a very capitalist way of thinking about the problem, but what "negative prices" actually means in this case is that the grid is over-energised. That's a genuine engineering issue which would take considerable effort to deal with without exploding transformers or setting fire to power stations
Home owned windmills, solar panels and battery storage solves that.
"put the excess energy into batteries" is an idea, and is already pretty much what is done, but the large scale implementation still requires a lot of time, effort, and expense.
In no home outside of fringe uses are any lights 12vdc, with the exception of maybe led strip lights for undercabs. They're all designed for 120vac. That lightbulb in the diagram is an e37/medium base for 120vac.
How, exactly, does that solve anything? It's not like we can add some kind of magic automatic residential cutoff system (that would just make it worse) and residential distribution is already the problem! Residential solar is awesome (tho home batteries are largely elon propaganda...) but they only contribute to the above issue, not solve it. There are ways of addressing it, but they're complicated and unglamorous.
I don't see why home batteries are propaganda. Those prices are plummeting and they have decent payback times in some markets.
The reasons for getting solar is the same reasons for getting batteries.
Because home batteries, while provisionally useful in the same way as a standby generator (though the generator is going to be far more eco friendly than the batteries over their respective lifetimes), is a vastly inferior solution to the implementation of even local grid scale solutions. Also because there is essentially 0 infrastructure designed to handle said batteries, they wear out quite quickly at home scales (unless you're using uncommon chemistries, but if you're using iron-nickle batteries you're not the target audience here) and because Elon popularized them with his "powerwall" bullshit entirely to pump the stock value of Tesla's battery plant (which is it's own spectacular saga I encourage you to look up, it's a real trip).
Batteries in the walls are useful in niches, but the current technology which uses lipo/lion/lifepo4 chemistries is inherently flawed and a route to both dead linemen and massive amounts of E-waste. They could be useful potentially, but as it stands, it's really bad right now.
After installation, a home owner has free electricity? I'm not trying to solve the issues for the power grid people, they have teams of people for that.
Spain and Portugal had almost complete blackouts today. You know who wouldn't have had blackouts? The people with their own solar panels and windmills.
I acknowledge that there's no real way to communicate sincerity online, but I'm gonna go ahead and promise I'm not trying to be a dick here when saying this:
I think you're bonking up on the Dunning Kruger limit here, because that's absolutely not how it works. Not only are the vast majority of homes not candidates for useful solar installs (you can pay someone to do it, but holy cow nearly every residential solar installer is a scam looking at you, Lumio International (how's that RICO case going?)), but solar for home-use power generation is very much not the norm for a whole host of reasons (dead linemen one of the biggest ones) and the safety considerations for implementing it generally make it an onerous enough task to manage that it's appeal is restricted largely to special interest users (homesteaders, preppers, S&R, power system enthusiasts, van life, etc ). There are ways this could be mitigated, but it would require a massive grid overhaul and additional constant upkeep beyond what any current grid already requires.
Here in Australia 37% of households have rooftop solar. Hardly "only special interest groups".
Australia is an edge case for everything solar and I'll quite happily admit that! Yay Australia, well done. That said I'd be very willing to bet that the majority of those are not-above-50%-ideal installs (don't take that bet, I'm cheating)
Sorry, you've misunderstood, I was talking about direct home power generation being special interest, not residential solar in general. Aussies don't have a higher rate for direct power generation than anywhere else because grids are, by and large, all suffering from the same fundamental design issues. I'm not at all attempting to argue that solar installs in general are special interest, and especially with the incredibly well thought out incentives the aus gvmt has been offering for both new construction and residential conversion/installation. 100% best handling of it in the world right now.
Of course we can. They're called Microgrid Interconnection Devices (MIDs).
Microgrids that can disconnect from the utility at appropriate times may in fact make it better. If homeowners responded to utility alerts of high demand and opted to disconnect from the grid during those times while still having power, that would just make grid operators and home owners happier.
Microgrids are the solution!
While residential BESSs are largely Tesla based, they are absolutely key in the energy transition from fossil- to renewables-based power sources.
How?
Which ways?
MIDs are in fact one of the bigger ones! That said, all the ones I have worked with are promising but are as-yet still unreliable enough that municipal adoption has been mired in safety concerns and the usual nonsense. To be honest that's been ever since they were first added to the NEC (admittedly most of this initially was based on speculative concerns), because of course. There are still warranted concerns with the implementation of microgrids, including things that are obviously bullshit like a lack of confidence in the reactivity of stations to the potential for excessive peaking large residential adoption of home batteries might cause, but also much less bullshit things like the complicating risks of having very large lithium-based batteries present in a residential fire.
They are not insurmountable concerns, but they are ones that need answering and are not a small part of why I say that currently, home battery storage solutions just aren't there yet. Local-grid facilities (what one of your sources calls a Mini-grid) are currently the best solution, which is why so many utilities are installing them. I've no doubt that the issues will be worked out, and although it will be some time before the technology matures to where the economies of scale present at municipal scales are no longer a driving consideration, it'll probably get there.
very minor stuff
Is this what you'd intended to link here, because while you're factually accurate in their necessity and I'm not disputing your claims, as far as I can tell the source here is only discussing local-municipal ('mini grid') installs, not microgrid installs.
(edit: fixed some typos)
Sorry for the naive question, but is it no possible to send the excess electricity to the ground (in the electrical sense)?
To effectively waste electric power like that would take quite a bit of effort. It would be easier to make a giant heater that heats up air. But that would of course also be absurd. Just turn off the wind turbines etc. to reduce power generation.
Nothing an open/close gate couldn’t fix. The real problem is how overly complicated we feel we need to make things.
This is some real "basic biology" level thinking here. Even if it were as simple as "Pull the lever Krunk!" then you've just turned all that solar infrastructure into junk for the majority of the time that we need power.
People use the vast majority of electricity in a day in the afternoon and at night - times that are noticeably after the peak solar production time. So you have all that energy going into the system with nowhere to go because battery technology and infrastructure isn't there, and then no energy to fulfill the peak demand. This is an issue nuclear runs into as well because a nuclear plant is either on or off and isn't capable of scaling its power to the current demand.
There are times where power companies have to pay industrial manufacturing facilities to run their most energy consuming machines just to bleed extra energy out of the grid to keep it from overloading and turning into a multi-million dollar disaster that could take years to get people back on the grid.
The grid is always over energized. That’s not a problem. Large solar and wind farms connect to the grid with great specificity about the maximum amount of energy they will put on the lines. The problem would be not enough energy. Batteries are beginning to solve the dispatch energy issue with renewables. As long as republicans don’t get their way and ruin renewable energy with unfair fossil fuel mandates, the grid will continue to modernize in this way and we’ll be fairly independent of fossil fuels in the future for electricity.
No it's not, it's energized just right. Otherwise you run into either over or under frequencies. Both pretty catastrophic.
In fairness, capitalist expansion is predicated on generating and reinvesting profit. If you build an array of solar panels and generate a revenue less than the installation+maintenance cost of the panels, you don't have any more money to buy new panels and expand the grid.
That is, under a privatized system, anyway. If you're a public utility and your goal is to meet a demand quota rather than raise revenue for the next round of expansion, profit isn't your concern. You're looking for the lowest possible installation/maintenance/replacement cost over the lifetime of the system, not the high margins per unit installed.
Incidentally, this is why vertically integrated private firms that consider electricity an expense rather than a profit center have been aggressively rolling out their own privately managed solar/wind arrays. When the concern is minimizing cost rather than maximizing revenue, and you can adjust your rate of consumption to match the peak productive capacity of your grid, then solar/wind is incredibly efficient.
thats why Westinghouse had to crush Nikolai Tesla. you can't meter wireless power.
