What is a Vienna converter?

The Vienna converter is a three-phase, three-level rectifier topology that has been widely adopted in high-performance grid-connected systems due to its combination of efficiency, low harmonic distortion, and bidirectional power flow capabilities. In this study, we selected the Vienna converter for the following key reasons: 1.

Can battery storage be used in microgrids?

Another use case for battery storage on microgrids is aggregating BESS as a virtual power plant (VPP) to correct imbalances in the utility grid. At the grid level, when the supply of power from renewables temporarily drops, utilities need to respond quickly to maintain equilibrium between supply and demand and stabilize the grid frequency.
