Abstract

This thesis presents a detailed comparative performance analysis of two Volt/VAr (Voltage and Reactive Power) control strategies in distribution networks. The study specifically examines the impact of implementing Volt/VAr control within multiple string inverters on the low-voltage side of a Generator Step-Up (GSU) transformer, in contrast to utilizing a centralized Power Plant Controller (PPC) located on the high-voltage side of a GSU transformer.

The work also estimated the loss in accuracy associated with modeling multiple string inverters as an aggregate, in contrast, to explicitly modeling each inverter and its linked string impedance.
