We describe a method for application-specific customization of dynamic phasors, intended for use in wide-area monitoring and control of electric power networks. In particular, we propose frequency-selective customization for accurate tracking of time-variant harmonic content under both steady-state (nearly-periodic) and transient operating conditions. Our approach relies on a recently introduced family of generalized dynamic phasors obtained via a so-called Phasor Bank transform. We provide an explicit compact characterization of the optimally-robust reconstruction stage of this transform, which can be used with any (customized) choice of its analysis stage. Since the phasor bank transform allows causal delay-free perfect reconstruction of any input waveform, it is perfectly suited for (closed-loop) control applications.
