I'd love to upvote, but come on, that "Master of puppets" devilish Netanyahu just screams "antisemitic clishés". We don't need shit like that to criticize genocide and zionist propaganda.

Where are you, a big city or a small town? In the US or elsewhere?

It may be hit or miss, but depending on where you are, there may be people willing to help without expecting monetary compensation. Charities, e.g. by religious groups, or mutual aid groups (the latter especially in big cities).

I wish you all the best, no person deserves to be abandoned like that.

We're talking about engineers here! We're using MATLAB or Python if we're programming at all.

Whoever wrote this has an extremely outdated technical understanding of renewables and energy storage... or wants to push this outdated understanding out of an economic interest/agenda.

Yes, a stable AC grid needs inertia, which was historically only provided by the generators in gas, coal and nuclear power plants. Yes, inverter-connected systems like batteries and PV plants don't provide inertia naturally. But there are control algorithms out there which would enable these systems to provide inertia just as well... And they could be going into large-scale rollout at least on new batteries and wind power plants within months if it was required by grid codes or incentivized by a market.

I agree that, whatever exactly happened initially, led to a disconnect of the mostly photovoltaic generation in Spain (not yet outfitted with such synthetic inertia algorithms) and the central European grid where more natural inertia was available. The high local PV surplus no longer exported to Europe led to an enormous increase in the grid frequency. The PV plants disconnected which led to a just as quick decrease of frequency and an automatic disconnect of loads - boom, the grid is dead. So far, their analysis was also what I presented to my students on Tuesday. But drawing the conclusion that renewables are bad just reveals either incompetence or an insidious agenda.
