My knowledge of turbines is about a century out of date, so please be so good to add everything you know to this discussion. As I understand it:. It used to be that every turbine on the grid was synchronized and people found out how the grid communicated its energy behaviour by changing frequency. This happened as emergent behaviour, almost by accident. As the grid operators came to rely on it, newer technology has to emulate it. But today, most of Europe shares the same grid, which was impossible at the time. There have to exist technological advances to make this possible. And solar doesn't even have an inherent frequency, it's DC. So what you say sounds very reasonable. But I hope never to see from close by what happens if modern energy equipment fails catastrophically.
