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) Module circuit (b) Symbol for module section 5.2 was used to regulate the average dc bus voltage (Vdc+ + Kk-)/2. The overall test ... But in the computer simulations, the inverter M3 was modeled as a single-phase microgrid inverter. The parameters of ... 5.17: Circuit diagram of the asynchronous intertie test system. Fig.
