Abstract
The new age idea of a smart grid is attracting a lot of interest in the power systems research area and industry. Utilities are concerned about the increasing energy demands and strict regulatory initiatives set up by the reliability councils. There has been large amounts of investment by Department of Energy in several Smart Grid Demonstration projects across the country to quantify the benefits of a smart grid. The Pullman Smart Grid Demonstration project in the state of Washington is one such project and is led by Avista Utilities This thesis explores the Volt/VAr control (VVC) scheme to be implemented on the thirteen feeders in Pullman, WA. Actual feeder models and load data is used and the analysis has been conducted in SynerGEE, a distribution software tool on two feeders. Initial VVC results show a 2-2.5% decrease in demand for 2.5-3% decrease in voltage for one distribution feeder. Further analysis with capacitors, voltage regulators, and smart meter data resulted in a more accurate analysis. Various capacitor control techniques and placement, control of voltage regulators are explored and simulation results are analyzed. Data from smart meters is used to further improve the performance of the proposed scheme.
