Abstract

The MicroGrids (MG) are essential structures for the advancement of smart grids. However, some particularities, such as the reduction of the inertia of such systems are challenges for its proper operation, mainly throughout the islanded operation mode. Thus, this article adopts the control of synthetic inertia through the Battery Energy Storage System (BESS). In order to make sure of the proper BESS operation, a management system is proposed, supported by the Rate Of Change Of Frequency (ROCOF) and the current State Of Charge (SOC). The results showed the stage of BESS load for normal conditions of operation and the contribution of the synthetic inertia, evidencing a reduction of the rate of change and frequency deviation occasioned by the unbalance between demand and generation due to the islanding and, consequently, a formation of a MG.
