Voltage measurement location for state estimation in embedded distribution system

State estimation is important for the automatic management and control of complex distribution networks with significant distributed generation. State estimation has been used extensively on transmission systems where, generally, measurements of bus bar voltages and line power flows exist. However, distribution systems normally have only a limited number of measurements. In such systems, additional measurements are expensive and careful selection of location becomes important. This work presents a iterative approach to identify potential points for location of voltage measurements for state estimation as part of a proposed distribution management system. The developed technique identifies measurement locations to reduce the voltage standard deviation of the bus bars, which do not have a measurement. The algorithm is tested with IEEE and TNEB benchmark systems.
