AI High Voltage Work Planning

Grid operators need better ways to handle congestion on transmission or distribution networks, where power flows can exceed safe limits and create reliability and cost issues. It addresses the problem of power grid congestion due to the increasing use of renewable energy sources, which can lead to inefficiencies and higher operational costs. Frequent renewable-driven voltage swings were forcing Chubu Electric Power Grid to switch stabilizing devices on and off too often, increasing wear, maintenance, and replacement costs on a long, slim transmission network.

The Problem

“AI High Voltage Work Planning for Congestion and Voltage Control”

Organizations face these key challenges:

1

Power flows exceed thermal or stability limits during renewable peaks

2

Voltage swings cause frequent on/off switching of stabilizing equipment

3

Manual planning cannot keep pace with intraday renewable variability

4

Operators must balance reliability, cost, and curtailment under uncertainty

5

Long, slim transmission networks are sensitive to reactive power and voltage instability

6

Existing rule-based controls are conservative and create unnecessary asset wear

7

Data is fragmented across SCADA, EMS, historian, outage management, and weather systems

Impact When Solved

Reduce renewable curtailment through earlier congestion prediction and optimized mitigationLower switching frequency for capacitors, reactors, and voltage stabilizing devicesCut maintenance and replacement costs caused by excessive equipment operationsImprove N-1 security planning and operational reliability on long transmission corridorsShorten operator decision time for day-ahead, intraday, and real-time planningIncrease usable transfer capacity without compromising safety constraints

The Shift

Before AI~85% Manual

Human Does

  • •Review one-line diagrams, outage requests, and switching procedures to define the work scope and sequence.
  • •Coordinate with operations, protection, outage management, and field crews to confirm constraints, clearances, and timing.
  • •Build and revise schedules in spreadsheets based on asset condition, permits, workforce availability, and expected customer impact.
  • •Validate safety, reliability, and regulatory requirements through manual checks and expert judgment.

Automation

    With AI~75% Automated

    Human Does

    • •Set planning priorities and approve recommended work windows, switching sequences, and outage plans.
    • •Review AI-flagged conflicts, safety risks, and data gaps and decide how exceptions should be handled.
    • •Confirm regulatory, safety, and operational compliance before releasing the plan for execution.

    AI Handles

    • •Fuse topology, load, asset health, outage history, permits, and workforce data into a current planning view.
    • •Recommend lower-risk work windows, switching sequences, and resource allocations based on predicted outage and restoration risk.
    • •Automatically check constraints, detect schedule conflicts, and flag missing clearances or inconsistent assumptions.
    • •Estimate job duration, crew needs, and likely customer interruption impacts across planning scenarios.
