Grid reliability studies for 3 gw of computational load

Challenge

A load of this scale creates voltage, stability, and contingency risks that existing frameworks were not designed to handle. Power-electronic-dominated behavior introduces dynamic risks relating to large block trips and rapid reconnection, sub synchronous interactions, and transmission upgrade timing all require explicit modeling and coordinated resolution.

Approach

Perform activities across three core areas:

• Sensitivity and risk analysis: Running sensitivity analyses on trip timing, reconnection logic, load ramp rates, and composite load interactions to access performance bounds.
• Integrated planning: Evaluating impacts across generation, transmission, and distribution to identify required upgrades and operational mitigations.
• Steady-state and dynamic modeling: Performing large load integration studies including steady-state, transient stability, and dynamic performance assessments.

Results

• Performed large load integration studies encompassing steady-state, transient stability, and dynamic performance assessments.
• Developed and tested multiple dynamic load model configurations, including user-defined models, to evaluate system stability impacts.
• Conducted cascading risk screening, power quality assessments and grid strength evaluations to quantify system exposure.
• Ran sensitivity analyses on trip timing, reconnection logic, load ramp rates, and composite load interactions to define performance bounds.
• Evaluated integrated planning impacts across generation, transmission, and distribution to identify required upgrades and operational mitigations.
