Exercise No. 1: ACE Chart variation after Generation Loss

4 Exercise No. 1: ACE Chart variation after Generation Loss Purpose The purpose of this exercise is to illustrate what happens to ACE in a simple system following the loss of generation. During this exercise you (PALCO Balancing Authority) will lose the Crawford 2 unit, a loss of ~335 MW of generation. This is a little under 7% of total online generation in the PALCO Balancing Area at the time.

5 Results: Record the following Values after the Unit Trip: Maximum Frequency Deviation: ___________ Initial Frequency Recovery due to Governor Droop: ________ Did BA meet DCS? YES/NO

11 Advanced Exercise No. 1 Objectives To be able to operate under emergency conditions.

12 Background Weather is normal, no storms forecast. It is 2 PM Your system Net Scheduled Interchange is 0 MW All units are on-line except the 70 MW Baker Unit and 80 MW Uxbrdg Unit The Amus unit is removed from service for emergency repairs for 48 hours. All NERC and FRCC Reliability Standards and Procedures are applicable.

22 Advanced Exercise No. 2 Objectives To be able to plan for a system emergency.

23 Background All NERC and FRCC Reliability Standards and Procedures are applicable. The sales are non-firm contracts.

24 Advanced Exercise No. 1A You are assigned the responsibility of drafting a System Restoration Plan for your system. You have only one unit capable of blackstart – The Baker Unit. Determine the path you will use to bring start up power to the Crawford Units 1 & 2.

27 This exercise will bring Murphy’s Law into play. Here are the assumptions: A severe storm moved through the Crawford area and both Baker to Crawford 230 kV lines No. 1 and 2 are out of service for repairs. This storm precipitated a blackout. Baker is the only black start unit. Start-up Power is required for the Crawford Units 1 & 2. Write a switching order to bring startup power from Baker to the Crawford 1 and 2 Units.
