Abstract:
This paper presents the design and implementation of a resonant controller into a PI-P control configuration (PI-P+Resonant controller). The design of this controller is conducted for inverter operation in island mode within the context of microgrids The main PI-P control is avoid that large control signal causing the saturation phenomena in the systems. The Resonant controller allows providing high gain at the frecuency of the harmonics, in order to mitigate these harmonics. If both controller are combiate (PI-P-Resonant controllers) turns out to be an adequate solution to reduce total armonic distortion in the output voltage (THDv) of a single-phase inverter due to nonlinear loads.

Index Terms:
PI-P controller, resonant controller, single phase inverter, microgrid.
