Integrated power systems versus early turbo-electric drive

Beyond the name, how does a modern integrated power system differ from the turbo-electric drives used on older American warships?

Modern systems integrate propulsion and every major electrical load, use far more efficient machinery and controls, and can distribute redundant generating capacity to preserve capability after damage or during maintenance.

The underlying electrical principle is familiar from early turbo-electric ships, but modern machinery, metallurgy, control systems, and efficiency are much more capable. An integrated system supplies propulsion, sensors, weapons, and hotel loads from a common electrical architecture, with sensors and weapons often imposing the largest demands. Multiple generators allow operators to triage the electrical network after damage instead of treating propulsion and combat systems as isolated loads. Designing generating capacity at about 150 percent of expected demand would let a ship absorb damage or take machinery offline for maintenance without losing its operational output.
