Abstract

Penetration of renewable energy sources in distribution network is accelerating in recent years, and it becomes more important to supervise voltage fluctuations in distribution lines. Meanwhile, there are projections to deploy smart meters at each customer site in many regions, and it is expected that smart meter measurements are effectively utilized. In order to monitor the distribution line voltage, we proposed an estimation method for distribution network voltage utilizing smart meter measurements, whose feature is a capability to reduce the estimation errors against distribution line parameter uncertainties. The effectiveness of the estimation method was confirmed by simulations.
