Electrical distribution networks state estimation

Many of the past work on distribution state estimation have been focused on the adoption of a transmission state estimation approach, without necessarily accounting for specific requirement distribution networks analysis. On distribution networks, typically, there are very few real-time measurements, and power consumption of each load is very uncertain. This paper presents an alternative approach to distribution state estimation with limited Real-Time Measurements Points (RTMP). This method includes two steps; in the first step Correlation Coefficient (CC) between power consumption of each LP and RTMP with usage of least squares (LS) is determined. In the second step; with data of RTMP, CC and forward backward load flow modification, excellent state estimation of electrical distribution networks can be determine.
