Title: High and Low Voltage Mitigation in Distribution Systems using a Residential Static Volt-Ampere Reactive Compensator

Program: Doctor of Philosophy in Electrical and Computer Engineering

Advisor: Dr. Said Amhed-Zaid, Electrical and Computer Engineering

Committee Members: Dr. Thad Welch, Electrical and Computer Engineering and Dr. Nader Rafla, Electrical and Computer Engineering


A new single-phase device, Residential Static Volt-Ampere Reactive Compensator (RSVC), is proposed as a way to mitigate high and low voltage issues in distribution systems caused by high penetration of Distributed Generation. The proposed RSVC consists of a fixed capacitor that works parallel with a Pulse-Width Modulation (PWM) switched reactor. The PWM switching is performed via a state machine that prevents the inductor from being open-circuited or short-circuited. Loss Sensitivity Factors are used in conjunction with Quasi-steady-state time-series simulations to identify the buses that can host an RSVC in a residential feeder with voltage issues.
