Abstract

This paper presents a novel digital control strategy for the islanding mode operation of a power electronics based energy management system (EMS). Thanks to the use of a high performance repetitive controller combined with active damping, the EMS is capable of supplying a high quality sinusoidal voltage to critical loads when the ac grid is not available. The proposed control scheme is analyzed and implemented in a FPGA based control platform; it achieves a very low output voltage THD and holds a large stability margin for a wide range of load conditions. Analysis and simulations demonstrate the superiority of the proposed controller versus open loop control. Laboratory experiments with linear and non-linear loads validate the model used for the simulations that demonstrate the excellent performance of the new control strategy.
