Description

technical field [0001] The invention relates to the technical field of optimal configuration of micro-grids, in particular to an optimal configuration method for AC-DC hybrid micro-grids. Background technique [0002] Microgrid is one of the effective ways to utilize new energy. In recent years, more and more renewable energy sources have been connected to the grid in the form of microgrids and have been well utilized. However, with the increase in the types of distributed power sources and the growth of DC loads, the structure of the AC microgrids commonly used in the past The limitations of the DC microgrid are becoming more and more obvious, and the pure DC microgrid also has disadvantages such as expensive converter equipment and high reactive power consumption. The AC-DC hybrid microgrid combines the advantages of the AC microgrid and the DC microgrid, and can effectively integrate a variety of distributed power sources and energy storage devices into the distribution ...
