Question
For the power system given below: Identify the generator, slack and load buses. Upon completion of a full AC power flow study, what quantities have been determined? That is, list all the bus voltage magnitudes and phase angles that are calculated in each iteration of the AC power flow study. Do not perform any calculations. Repeat part b for the Fast Decoupled power flow. Briefly discuss the similarities and/or differences between the values of the bus voltages obtained from the full AC power flow and the values of the bus voltages obtained from the Fast Decoupled power flow.Explanation / Answer
A)Bus 1 is slack bus as for slack bus voltage magnitude and phase angle are specified and real and reactive power at this bus is not specified
Bus3 is generator bus, as for generator bus voltage magnitude is known whereas reactive power and phase angle is unknown.
Bus 2 and bus 4 is load bus,as for load buses real and reactive power is known and voltage magnitude and phase angle is unknown .
