This paper presents a comparison between phasor measurement units' (PMUs') optimal allocation for system topological observability, and PMUs' optimal number and locations for minimum state estimation residual error. A newly developed technique based on discrete particle swarm optimization (DPSO) is used in finding the PMUs' optimal allocation for different system unobservability depth. For the optimal...
The phasors readings of the phasor measurement units (PMUs) are taken into consideration in state estimation analysis. The paper presents the effect of changing the locations and numbers of PMUs through the buses of the power network on the system state estimation results. A computer program is built and tested on 14- bus IEEE standard system. Also it is applied on a system depicted from the Egyptian...
A new modified discrete particle swarm optimization (DPSO) technique is developed to determine the optimal number and locations for phasor measurement units (PMUs) in power system network for different depth of unobservability. The PMUspsila readings are to be utilized using a newly developed technique for on-line voltage stability monitoring. The DPSO developed technique is tested on 14-bus and 57-bus...
