Abstract
The availability of phasor measurement unit (PMU) has provided a method of taking current and voltage phasor measurement directly, which makes linear state estimation possible. The implementation of PMUs is increasing and enough PMU placements can guarantee the system observability and measurement redundancy. The large number of PMU presence requires certain methods to lower the computation burden. The objective of this thesis is to implement a two-level linear state estimation which can utilize PMU measurements and estimate the states at both the substation level and the control center level. The architecture of databases, communications and application programs that are required to support this two-level linear state estimation is described. Besides, as the availability of phasor measurements may not be available for all buses in both real practical worlds and simulation environment, an optimal PMU placement approach suitable for the two-level linear state estimation is also introduced. The two-level state estimation is applied to two study systems. The first study system is the WECC 6000 bus system and the second one is the ISO New England system.
