Abstract: The present invention pertains to a microgrid system. A microgrid system according to an embodiment of the present invention is a microgrid system that is operated while separated from a power grid, wherein said microgrid system comprises: a first microgrid that includes a first load, a first ESS, a first distributed power system and a first controller; and a second microgrid that includes a second load, a second ESS, a second distributed power system and a second controller, and wherein a line connecting the first and the second microgrid is opened and closed using a relay, and the first and the second controller determine whether to open or close the relay by communicating with one another.

Abstract: The present disclosure provides a protective glass for a solar cell module having improved power generation efficiency of a solar cell obtained by minimizing reflection of light incident onto the protective glass, and a manufacturing method for the same. The protective glass for a solar cell module includes a plurality of glass beads formed in a spherical or hemispherical shape and arranged in the horizontal direction. The plurality of glass beads is disposed on at least one of the upper and lower portions of the sealing member. In addition, the method of manufacturing a protective glass for a solar cell module includes preparing a plurality of glass beads formed in a spherical or hemispherical shape, arranging the glass beads in a horizontal direction, and injecting a molten glass solution into the glass beads and forming the protective glass.
