In this work, a similar concept based on the three-layer control hierarchy for a microgrid is presented. The three-layer control architecture for battery management and control is shown in Fig. 2 where the main targets of each layer are detailed with solid lines and dashed lines representing the power flows and the information flows, respectively.
