Development Trend and Subjects of New Distribution Network Technology

Abstract

Because of real introduction of distributed power generation (DG) such as photovoltaic power generation, wind power generation, co-generation system and so on, it becomes necessary to investigate some technical measures of the utility distribution system to cope with the introduction of DG. The METI organizes about the directionality of technical development for the distribution system by some committees. Focusing on the result of the governmental investigations, this paper describes development trend and subjects of future new distribution network system which makes it possible to achieve smooth introduction of DG and to utilize DG successfully for load leveling, keeping power quality, enhancement of supply reliability and so on. © 2004, The Institute of Electrical Engineers of Japan.
