Abstract
The purpose of this thesis is to present a simulation model for the users to operate on a large-scale electric grid in a non-uniform dynamically varying GMD (Geo-Magnetic Disturbance) storm and to gauge their performance. Here the thesis introduces about GMD storm and then explains the various modifications in the design of synthetic grid to make this case as realistic as possible. This thesis then discusses various tools available for users to interact with the model. After this the next topic introduces about the performance metrics which will be used to gauge users’ performances. The two metrics System Frequency and Bus Voltages are inspired from the nodal operating guide of Electric Reliability Corporation of Texas. The rest of the metrics are the Unserved Load and Generator MVAR (Mega Volt Ampere Reactive) Reserve Capacity. Finally, the thesis compares the result of four scenarios using the performance metrics. These scenarios are the Do-Nothing scenario, Load Shedding Scenario, Inexperienced Operator Scenario, and the Experienced Operator Scenario. The result rates each of the performances and the results were showing that experienced operator performed better than the inexperienced and the do-nothing scenario, and the load shedding scenario though gives a good result but should be avoided unless the system is about to collapse.
