| File Type | Description |
| *mon.file | It informs load flow simulator the branches needed to be monitored when N-1 contingency happens. It also monitors and records the bus voltages within specific ranges or outside the range. |
| *sub.file | It tells load flow analysis to consider and perform at specific zone. It includes all involved power network elements in the case study. |
| *con.file | It is used to trip line or power elements to create contingency scenarios. Three types of contingencies: N-0 (system intact), N-1 (single power element outage) and N-2 (two power elements outage). In this case, N-1 is chosen. |
