The Power Flow Problem 5. For a certain bus type, when formulating the power flow problem, we reduce the dimensionality of the problem by removing the reactive power equation from the set of equations to be solved. What bus type is this? Explain why this does not result in an under-constrained problem such that there are more unknowns than equations. 6.
