I’m ignorant of the mechanism of solar panels and electrical grids…do they just explode if they are set up and not draining power?
Because why can’t you just cut the inflow of electricity on a signal? I’d appreciate actual answers.
Edit: In fact, I don’t see why “just don’t send the power if it isn’t needed” doesn’t work for any power generation source. In lieu of answers, I can imagine the issue is with the non-renewable resources. Maybe you want to spin down burning generators, if you don’t need the extra energy. So it’s a planning problem to know when you don’t need energy, so you know when you don’t need to burn resources.
But you don’t waste wind if you just let the turbines keep spinning while blocking of energy output. Sunlight isn’t burnt up if solar panels keep slurping while the downstream draw is blocked.
Is this a problem being baked in because it’s assuming “burnable fuel” restrictions?
We setup a 25kw setup recently in Pakistan but ran out of money to have inverter and batteries for it. So far they have been up for a couple months, none have exploded yet.
Solar panels have no problem if nothing consumes the power they can produce.
Wind turbines can be feathered and the turbine break engaged until they stop, at which point they’re not generating anything.
So negative energy prices are not really a technical problem of renewables, rather they’re due to the way the decision of “who stops their generation” being left to market systems - rather than there being some kind of centralized control, possibly with agreements in place, that decides which generators are stopped first when there is excess generation, market prices just float as offer and demand float and individual suppliers are left to individually decide if it’s worth it for them to generate for a given price or not and thus if they should reduce or stop their generation.
There are delays and inertia in the whole process of signalling demand/supply balance via market prices, so there result is that the price can overshot and undershot, the latter being sometimes all the way down to negative prices.
we can just put a white blanket on top of the panels…
