An improved state estimation algorithm and its implementation for distribution networks
Single-phase power system state estimation is widely used in the industry to identify the current power system operating state due to its relative accuracy. However, it is less accurate for low-voltage distribution networks, such as the 15-bus network system in the Lab of Clean Energy Resea...

| Summary: | Single-phase power system state estimation is widely used in the industry to identify
the current power system operating state due to its relative accuracy. However, it is
less accurate for low-voltage distribution networks, such as the 15-bus network
system in the Lab of Clean Energy Research at the Nanyang Technological
University, To that end, improvements to the existing single-phase Weighted-Least-
Square state estimation software has been set down as a goal for this project.
This project has seen the implementation of a three-phase Weighted-Least-Square
algorithm that incorporates Kirchoff’s Voltage Law and Kirchoff’s Current Law. The
implemented software estimated system state with higher accuracy compared to the
existing software for the IEEE-14 test bus system. Another three-phase power flow
algorithm, the Newton Raphson power flow method [1] was also explored and tested. |
