Integrating synchrophasor technology with the Oregon State University campus smart grid project

The paper presents the initial study on the integration of synchrophasor infrastructure within the Oregon State University (OSU) Corvallis campus smart grid project. Two popular approaches for transmission level synchrophasor placement are preliminarily applied in a benchmark distribution level network, and subsequently compared in order to evaluate their performance. The first method utilizes a linear optimization approach given the network electrical distances; the second method inspects the sensitivities of bus voltage and angle with respect to power injection by running ac power flow. Moreover, it considers additional constraints and rules such as the size of system and local operating policies/priorities. Finally, a few candidate solutions are identified for the placement of synchrophasors on the OSU-Corvallis campus. This project also builds a geographical campus grid model in PowerWorld to better visualize the experiment outcomes.
