What are the dynamic reactive reserves currently on this generator? a) 50 b) 30 c) 0 d) 20 - Correct Answer: d) 20 A Balancing Authority has a Frequency Bias Setting of -200 MW/.1Hz. What is the Balancing Authority's Frequency Response for a frequency of 59.95 Hz? a) 10 MWs b) 50 MWs c) 100 MWs d) 200 MWs - Correct Answer: c) 100 MWs A Balancing Authority is scheduled to receive 300 MWs from the north and 400 MWs ...

Generating units jointly owned by two or more Balancing Authorities may be modeled in the AGC systems as a "virtual" tie line flow (pseudo-tie). To properly account for the jointly owned unit as a pseudo-tie, each Balancing Authority must include a portion o fthe unit's MW output as an adjustment to the ________ in its ACE equation. net actual interchange (NIA) A dynamic schedule is commonly used for scheduling jointly-owned generation between Balancing Authority Areas. To properly acco...

A Balancing Authority notices that Operating Reserve has steadily declined throughout the hour. What is the most likely cause? a) Loss of a large generator in the area b) An inaccurate load forecast c) Loss of a major transmission line d) A malfunction of EMS b) An inaccurate load forecast Balancing Area A notices that the Interconnection frequency is 59.94 Hz and their ACE is 0. Which of the following could be the cause of this reading? a) A net under-generation in Balancing Area...

You are an external BA with a frequency bais of 20 MW/.1 Hz that sees a frequency of 60.02 due to a large loss of load in the contingent BA. If your generator governor control systems responded to the frequency deviation approximately how much of a generation change would you BA experience? -4MW Net actual interchange minus Net scheduled interchange is what? Inadvertent interchange Suppose your interconnection operators at 59.97 Hz from one minute after midnight to noon and operate a...
