Microgrid field test experiences in Japan

In Japan, three field tests of microgrid were started in 2005. The DER (distributed energy resources) capacity of each microgrid is 710, 750, and 2400 kW, respectively. A field test of voltage control for a distribution feeder connected with multiple PV systems was started in 2003. In this paper, at first proposed microgrid control system is outlined and then field tests outline is stated
