Abstract

Microgrids are receiving tremendous attention due to increasing need to integrate distributed generations (DG) and to provide reliable power to critical loads. Proper power management in microgrid is required to regulate the system voltage and frequency, maintain power quality, and manage DGs. A microgrid system has been studied. A microcontroller method for two parallel inverters which represent two DG in microgrid is proposed and described in details. The proposed technique has been applied to adjust the frequency and voltages of the two inverters to suit the grid requirements in various operating mods in order to manage the system and improve its efficiency.
