In the conventional droop control method employed in the primary control layer, there is an inherent tradeoff between current-sharing accuracy and voltage regulation. Consequently, to achieve both accurate current sharing and maintain the bus voltage at its nominal value, secondary control schemes are implemented. Nevertheless, a proper design of control parameters of an electrical power system (EPS) is important as it has a huge impact on its stability and dynamic features. To that end, this article proposes a novel artificial intelligent-based design strategy for the optimal design of the power sharing and bus voltage compensation coefficients for the islanded more electric aircraft (MEA) EPS dc microgrid. Through the proposed approach, the bus voltage regulation and dynamic performance of the MEA EPS are improved in different EPS operation conditions when compared with the state-of-the-art methods. Furthermore, the safety and continuous operation of the electrical loads onboard the MEA are guaranteed. The proposed control approach can be conveniently implemented since there is no need for additional controllers and existing communication infrastructure such as power line communication can be utilized. The effectiveness of the proposed approach is validated in both simulations and hardware-in-the-loop experiments.
