Performance Assessment of Distributed Control in Micro-Grid

DGs in a micro grid as agents which requires only own information and the information of some neighbors. Input–output feedback linearization is used to control tracker synchronization problem and complex communication network used which improve the system reliability. The control is responsible to maintain the voltage and frequency of the micro grid within the acceptable ranges. To achieve a dynamic variation for the output active power ratios among the distributed energy resources, the distributive cooperative control has to adjust the references of frequency for the rated active power and the references of voltage for rated reactive power. The proposed control may lead to unacceptable voltage and frequency in the micro grid and has to adjust the references of the voltage and frequency consequently. The developed novel solution takes into account the converters parameters as apparent power limit and maximum active power which balance the system and improves reliability. The control parameters and its effectiveness for a desired response speed verified by the simulation of a micro grid test system.
