Steady-State and
Contingency Analysis
Evaluates normal and N-1/N-1-1 grid conditions to ensure reliable interconnection without
overloading equipment.
Stability Analysis
Assesses system behavior during disturbances to verify voltage, frequency, and rotor angle
stability.
Short-Circuit Analysis
Determines fault current levels to validate breaker ratings and protective device adequacy.
SCR (Short-Circuit
Ratio) Analysis
Measures system strength at the point of interconnection to ensure stable inverter operation
and control performance.
Review of Protection
Settings
Verifies relay coordination and protection schemes for safe fault detection and clearing.
Frequency Response and
Ride-Through Capability
Evaluates project performance under grid disturbances.
Model Validation and
Parameter Tuning
Ensures PSSE and PSCAD models accurately reflect plant behavior.
Transformer
Energization Study
Analyzes inrush currents and switching transients to mitigate energization impacts on the grid.
Reactive Power
Capability Analysis
Confirms the plant's ability to meet voltage control and power factor requirements under all
conditions.
Evaluation and Cost
Estimation of Upgrades
Identifies required transmission upgrades and provides high-level cost estimates for
interconnection.
Unintended Islanding
Study
Evaluates risks of the plant unintentionally energizing a de-energized grid section and
proposes mitigation measures.
Deliverability Analysis
Assesses the ability to deliver full output to the grid under various system conditions without
curtailment.
Grid Compliance Support
End-to-end assistance with ISO/TSP interconnection requirements and technical approvals.
