| dc.description.abstract | The Phasor Measurement Unit (PMU) introduces new functionality to the measurement spectrum, with accurate time tagging and synchronization capability, and is thus the next step in the technological evolution of state estimation in electrical power systems. This thesis presents the theoretical basis behind a two-pass hybrid linear state estimation model, the aim of which is to utilize PMU measurements in conjunction with classical state estimation. Following this, the construction of a hybrid linear state estimator application is discussed. Numerical simulation has been conducted to evaluate the feasibility of the model as a way of utilizing the increasing availability of synchrophasor measurements to improve state estimation. The results indicate a significant potential improvement of state estimation, especially in aspects of monitoring dynamic behaviour within the system. | |
