| Abstract: | A Hamiltonian surface shaping power flow control (HSSPFC) method is used
to analyze the meta-stability and adjust pulsed power loads on a DC
electric power distribution network. Pulsed power loads are nonlinear,
time-variant systems that cause nonlinear limit-cycles. During the on
periods of a pulsed load, the system can be in an unstable state and is
damped back to stability during the off state of the load. Therefore,
over the entire period of the pulse the system may only be assessed as
meta-stable. As shown through simulation, HIL and hardware results, the
HSSPFC method is more accurate than the other small-signal approaches,
such as Eigenvalues, Nyquist, and Floquet theory, and can reveal
important details about the transient responses and performance. |
