Resumo

This paper proposes an adaptive droop control strategy for simultaneous regulation of voltage and frequency in isolated microgrids to meet the relevant legislation (NBR 5410 and IEEE 1547). The technique is based on the traditional structure of the Droop control (P-f) and (Q-V), aided by recursive least squares methods to estimate the line parameters. The control law is adaptive because the controller gains are self-adjusting to the operating conditions imposed by the loads and the legal restrictions for fluctuations in voltage and frequency in the microgrid. The controller was validated in different microgrids (1-bus, 3-bus, and IEEE 14-bus) and different types of loads. The simulation results show the effectiveness of the controller: rapid response in the accommodation of variations in loads; active power-sharing between the inverters and; stable and safe operation of the microgrid.
