Abstract
Power systems engineers lack the capability of knowing the real time status of the system and its vulnerabilities. Digital twins are introduced as a solution for distribution system applications and security.A digital twin's ability to perform real time calculations and analyses make it a unique tool that can strengthen our understanding of the power grid, mitigate threats, and improve decision making. Investigating how digital twins' application in power systems can help improve its efficiency, reliability, and functionality. A digital twin is used in this thesis to model and show the impact of the addition of distributed devices to enhance the reliability of power systems in rural areas.
Utility customers expect the highest levels of reliability as many day-to-day activities involve loads requiring a constant energy supply. In urban areas, to ensure this reliability factor, many utilities use networked systems to add redundancy in the event of an outage. In rural areas, however, lower population densities and power system branches cause the reliability techniques used in urban areas to become less practical. Consequently, customers in rural areas experience more outages and longer outage times due to the distance between customers.
Current research focuses on the integration of distributed generation to support rural circuits. This thesis will explore the impact of also integrating distributed storage in rural systems at the edge of the grid. These models will evaluate how these feeders accommodate new devices and how they impact the reliability of the circuit. The creation of these system models will help create a foundation for the development of a digital twin, which can be useful for utility personnel. The addition of newer devices will provide the utility more data to not only train their digital twin and run more accurate studies, but also better monitor and understand what is occurring on the rural circuits to make more informed decisions.
