What does Volt/Var Control and Optimization manage?
The correct answer is B. voltage levels and power quality. Volt/Var Control and Optimization (VVCO) is a grid management function specifically designed to regulate voltage levels and reactive power (Var) across the distribution network, directly improving power quality and reducing energy losses - making B correct.

Explanation
Volt/Var Control and Optimization (VVCO) is a grid management function specifically designed to regulate voltage levels and reactive power (Var) across the distribution network, directly improving power quality and reducing energy losses - making B correct.
Why the distractors are wrong:
- A (Fault Location Isolation) is managed by FLISR (Fault Location, Isolation, and Service Restoration) systems, not VVCO.
- C (Compliance/Regulatory) is an administrative/governance function, not a real-time grid control operation.
- D (Service Restoration) is also part of FLISR - it handles switching operations after a fault is isolated.
Memory tip: Break down the acronym - "Volt" = voltage levels, "Var" = reactive power/power quality. VVCO literally tells you what it manages in its own name.
