A Study for Actual Operation of Voltage Estimation in Distribution Systems Using Smart Meters

Toward the solution of the global climate change problem, efforts are underway in Japan to achieve carbon neutrality and to reduce greenhouse gas emissions to zero overall. In recent years, renewable energies have become more widespread, but power flow have become more complex, and there is concern that power quality in the distribution system will deteriorate. In order to maintain power quality, a detailed understanding of power conditions is necessary. In this paper, we focus on the voltage management of the distribution system and introduce a method for estimating the voltage of the distribution system.
