Disclosed in a stand-alone micro-grid autonomous control system including: at least one battery system directly changing a reference frequency thereof according to a charge amount, and providing power having the changed reference frequency; at least one power generator measuring the reference frequency from the power provided form the at least one battery system, and starting generating power or stopping generating power based on the measured reference frequency; and at least one load measuring the reference frequency from the power provided from the battery system, and performing a synchronization operation or a synchronization releasing operation based on the measured reference frequency.

Stand-alone micro-grid autonomous control system and method

The present invention relates to a super water-repellent organic/inorganic composite material, more particularly to a new-concept super water-repellent organic/inorganic composite material with superior separation property having skin layer chemically immobilized with functional polymer on the porous inorganic support surface with fractal surface structure and pores of nanometers to micrometers, using grafting-from surface polymerization method.
