The surplus electric power interchange effect among residential blocks by the smart grid judging from urban form

Abstract

To make effective use of solar power, studies of the interchange effect of surplus electric power through a smart grid have attracted attention recently. However, the interchange effect among existing blocks that vary in their characteristics has not been sufficiently clarified. Therefore, this study analyzed the interchange effect among residential blocks related to urban form and existing blocks. Results show the following: 1) urban sprawl forms with low-density population give little room for interchange among blocks; 2) an urban form including less-used land mixed with a dense population, with the housing type and population density differing markedly on each block, interchange of surplus electric power can be done efficiently among blocks; 3) the interchange effect is small in a compact urban form.
