And combustion engines have their ideal operating point. You usually want to run them close to where they are most efficient, and stress and wear is lowest, to minimize their costs. And there's more complications…
So you need to balance a lot of variables and the solution depends on many factors: What are the exact numbers we are talking here? What risks can we take? Is this the power supply for a weekend home? Or for a whole metropolitan area, with hospitals, traffic lights, and subways?

Enter batteries. Here, we use the term for electro-chemical assets which can both consume (charging) and produce (discharging) power. But they charge/discharge DC, so, like with PV power, you need to connect a string of batteries to your (AC) grid through an inverter which converts between AC/DC. The combination of a string of batteries and an inverter is often called an "AC battery" and usually controlled as a singular asset. Like combustion generators, battery inverters are grid-forming.
