These controllers leverage the information provided by the system identification method and enhance the Microgrid stability by increasing the power range of operation. The controllers combine non-linear control techniques with the traditional PI control structure, in which the proportional and integral gains vary according to the estimated load power, allowing it to maintain constant dynamics at all operating conditions.
