Abstract

Microgrids are designed to operate at a fundamental frequency (50 or 60 Hz). However, certain types of loads generate voltage and/or current harmonics that increase power system heat losses. These harmonic losses reduce system efficiency, cause apparatus overheating and increase power costs. Besides that, the Distributed Generation (DG) is expected to play an important role in future power systems, since it is able to reduce losses, improve power quality to end users. In this paper we propose new harmonic droop controller to compensate the harmonic currents produced by each DG to feed the nonlinear loads. Furthermore, the proposed controller is able to damp the total harmonic distortion of the voltage at the common connection point (PCC). Modeling and simulations incorporate to define the best control parameters for a proper operation. Experimental results are given to show the efficiency of the proposed algorithm.
