Minimization of Microgrid Impact on Distribution Network Systems Through BESS Real-Time Control

This work deals with the design and the implementation of a real-time control strategy aimed at minimizing the impact of Microgrids (MGs) on distribution networks. The proposed procedure employs Battery Energy Storage Systems to track desired active power profiles at the MG tie-line. The control logic relies on a PID regulator characterized by saturation limits whose dynamic setting depends on the state of charge of the storage unit. The controller has been tested on the field, with the aim of minimizing the tie-line active power of a real MG over a 24 hours time window. Experimental results prove the effectiveness of the developed procedure.
