Abstract
The new generation of smart meters can provide valuable information. “New generation” smart meters provide voltage magnitude and apparent power measurements. In addition, voltage angle measurements referenced to the substation can be added. The aim of this paper is to formulate a state estimation algorithm for power distribution system, using apparent power, voltage angle and voltage magnitude measurements at low voltage residential customers. The research is focused on the American distribution system, which ranges from medium-voltage substations to low-voltage consumers. The objective is to determine the state of a distribution network, using only measurements provided by smart meters. Simulations performed on an EPRI test network section show that the voltages in MV can be estimated from smart meter measurements.
