Distribution system state estimation device and distribution system state estimation method

摘要

The distribution system management device (1) according to the present invention receives measured values from a plurality of high-voltage sensors that measure the voltage and power flow of the distribution lines of the high-voltage system, and receives power from a plurality of smart meters that measure power. The communication unit (16) for receiving and a distribution line between two high-voltage sensors among the plurality of high-voltage sensors are divided into a plurality of sections, and the two measurement values received from two high-voltage sensors and the section-by-section A voltage control unit (15) for estimating a voltage distribution in the distribution line based on the amount of electric power.
