Resumen

This article presents a robust optimal control approach for an islanded microgrid. The control structure includes a voltage controller based on mixed H2/Hinf state feedback using linear matrix inequalities and a power controller based on droop characteristics. Due to uncertainties and nonlinearities in the system, a polytopic modelling approach has been used. The proposed controller aims to achieve stability of the closed-loop system, reject disturbances, balance the power among distributed generation units, and minimize energy consumption. In addition, regional pole placement is used to obtain well-damped transient responses. Simulation results demonstrate the effectiveness of the proposed controller in the presence of load perturbation and disconnection of a distributed generation unit. Moreover, the article compares the proposed controller with the Hinf controller.
