Abstract:In the case of high proportion of distributed energy access, the AC-DC hybrid distribution network has lower network loss and more flexible control ability than the traditional AC distribution network. In order to provide relatively accurate guidance for the AC-DC construction in the distribution platform area, the characteristic index boundary conditions should be analyzed. In the background of high proportion of photovoltaic access, the intelligent optimization algorithm to regulate the flexible equipment, and analyzes the boundary conditions of photovoltaic permeability, power supply radius and load capacity.
