If adjusted to 10 %, the setting will reserve that on the generators. In this way, the generator plant can always instantly supply the set
amount. The setting refers to the actual PV production, hence it is a dynamic spinning reserve because the pv production may vary.

Note that the spinning reserve setting can be taken from the ASC, or a PLC can write the data into the ASC. This is adjusted in the
last setting, and the default is "ASC settings".
