Regulation of the dc bus voltage of the BTB gateway by a PI controller driving the power set point of each VSC is shown to effect autonomous power exchange between asynchronous microgrids. A control-Lyapunov-function-based relative voltage angle controller is proven to minimize the power pulsations at the dc bus of a gateway between asymmetric single-phase circuits and a three-phase circuit. Results from computer simulations and laboratory experiments corroborate the theoretical predictions.... a power electronic load balancing compensator in a three-phase three wire system 13 2.1 Two types of periodic signals 24 2.2 Block diagram ... 47 3.3 Phasor diagrams for pulsating power balance in a single-phase pseudo-direct converter.
