Resumo

One of the main features of microgrids is their ability to operate in grid-connected and islanded modes. In each mode of operation, distributed energy resources (DERs) can be managed through grid forming or grid following control strategies. A microgrid may experience significant voltage and frequency fluctuations during unintentional isolation events. This papers proposes an adaptation of the control strategy known as Virtual Synchornous Machine with the aims to smooth the transition to islanded mode without depending on any external command signal for islanding detection. The proposed control strategy is applied to a 1 MW, 1.2 MWh Battery Energy Storage System that will act as the grid former in an 11.9 kV microgrid currently being deployed at the State University of Campinas (Brazil). Hardware-in-the-loop simulations result of the system with the control strategy implemented in a digital signal processor (DSP) are presented for validation. (AU)
