Abstract :
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 allocation of PMUs from the point of view of minimum state estimation residual error, a new methodology is used with a new hybrid state estimation technique. The comparison is applied to a large system depicted from unified electrical power network (UEPN) of Egypt. The simulation results are discussed in details.
