Optimal Placement of Phasor Measurement Units for Harmonic State Estimation in Unbalanced Distribution System Using Genetic Algorithms

This paper present a method to find minimum number of phasor measurement units (PMUs) for complete observability of power system network for normal operating conditions.A linear algorithm is used to determine the minimum number of PMUs needed to make the system observable. For state estimation and fault diagnosis in power system synchronized snapshot of whole system must be necessary. The proposed method is used to benchmark the optimal PMUs placement solution for the IEEE 14-bus, IEEE 18- bus, IEEE 30-bus and IEEE 57-bus test systems.

Simulation Results

With phasor measurement units (PMU) become available in the distribution system; the estimation accuracy of the distribution system state estimation (DSSE) is expected to be improved. Based on the weighted least square (WLS) approach, this paper proposed a new state estimator which takes into account the PMU measurements including voltage magnitude and phasor angle, and load current magnitude and phasor angle. Simulation results indicate that the estimation accuracy is obvious improve by adding PMU measurements to the DSSE. Furthermore, the estimation accuracy changes with the installation site of PMU, and can be maximized by choosing the installation site appropriately.

This paper present a method to find minimum number of phasor measurement units (PMUs) for complete observability of power system network for normal operating conditions .A linear algorithm is used to determine the minimum number of PMUs needed to make the system observable without considering zero injection buses. For state estimation and fault diagnosis in power system synchronized snapshot of whole system must be necessary. The proposed method is used to benchmark the optimal PMUs placement solution for the IEEE 14-bus, IEEE 18-bus, IEEE 24-bus, IEEE 30-bus and IEEE 57-bus test systems.
