Power System Analysis And Design SI Edition 6th Edition By Glover – Test Bank
True/False – Two points each. Circle T if statement is true, F if statement is False.
T F 1. Nonlinear equations, such as those for the power flow, can have
T F 2. Because of line resistance, the power flow Jacobian matrix is
guaranteed to never be singular.
T F 3. In the power flow the voltage angle at the slack bus does not
T F 4. The dc power flow solves for the per unit voltage magnitudes,
assuming that the voltage angles are constant at zero degrees.
T F 5. When solving a minimization problem adding contraints will result
in a cost function value that is greater than or equal to that of the
T F 6. In the PJM and MISO LMP markets generators are never paid
more than they offer into the market.
T F 7. In three-phase systems using symmetrical components, the
negative sequence is used to represent non-zero neutral currents.
T F 8. Economic dispatch primarily is concerned with determining which
units to turn on/off.
T F 9. In economic dispatch, the penalty factor at the slack bus is always
T F 10. When considering faults on high voltage transmission lines, such
as those operating at 500 or 765 kV, the most common type of fault
is the balanced three-phase faults covered in Chapter 7.
