The control center of the network collects
the system state of an electric power system through remote
terminal units (RTUs), for the processing and decision
making. Data transmitted to the control center should be
accurate and reliable enough for controlling a power system.
In order to have a reliable and accurate system state, the
utilities need to upgrade their SCADA system and install more
real-time measurements. However, the application of SCADA
for distribution system is limited and only available for
selected area. Moreover, in conventional operation of
distribution network, real-time information is very limited to
monitor the whole system at each point due to financial
constraints. Hence, this issue could be addressed by using
State Estimation (SE) method.
