What describes isochronous governor control in parallel operation?

Explanation:
In parallel operation, all generators must run at the same speed (frequency). An isochronous governor is used to hold that speed constant as load changes, so the system frequency stays fixed. To enable load sharing among several units, you use droop: the governor allows a small change in speed (and thus frequency) as load varies, which lets generators share the load in proportion to their capacities. So isochronous control keeps speed steady, while droop introduces a controlled speed change to distribute load across machines.
