This paper researches unsymmetrical voltage sag influence on torque ripple in scalar controlled (V/Hz), rotor field oriented (RFO) and direct torque controlled (DTC) drives. Electric drives performance degradation during voltage sag mainly depends on the used control algorithm. Industrial drives with all three types control methods are experimentally tested. Experiments with digital observer's application confirm the proposed solution. .

In this paper, the composition and structure of typical microgrid system are described briefly first. Different control methods of microgrid system and their advantages and shortcomings are analyzed in detail. The comparative analysis of different control methods is carried out. Finally, a practical control scheme of an example is proposed which provides a reference for related research and engineering practice.
