Spectral Clustering For Electrical Phase Identification Using Advanced Metering Infrastructure Voltage Time Series, Logan Blakely Jan 2019

Spectral Clustering For Electrical Phase Identification Using Advanced Metering Infrastructure Voltage Time Series, Logan Blakely

Dissertations and Theses

The increasing demand for and prevalence of distributed energy resources (DER) such as solar power, electric vehicles, and energy storage, present a unique set of challenges for integration into a legacy power grid, and accurate models of the low-voltage distribution systems are critical for accurate simulations of DER. Accurate labeling of the phase connections for each customer in a utility model is one area of grid topology that is known to have errors and has implications for the safety, efficiency, and hosting capacity of a distribution system. This research presents a methodology for the phase identification of customers solely using ...


Technology Planning For Aligning Emerging Business Models And Regulatory Structures: The Case Of Electric Vehicle Charging And The Smart Grid, Kelly R. Cowan Dec 2017

Technology Planning For Aligning Emerging Business Models And Regulatory Structures: The Case Of Electric Vehicle Charging And The Smart Grid, Kelly R. Cowan

Dissertations and Theses

Smart grid has been described as the Energy Internet: Where Energy Technology meets Information Technology. The incorporation of such technology into vast existing utility infrastructures offers many advantages, including possibilities for new smart appliances, energy management systems, better integration of renewable energy, value added services, and new business models, both for supply- and demand-side management. Smart grid also replaces aging utility technologies that are becoming increasingly unreliable, as the average ages for many critical components in utility systems now exceed their original design lives. However, while smart grid offers the promise of revolutionizing utility delivery systems, many questions remain about ...


Configuring The Urban Smart Grid: Transitions, Experimentation, And Governance, Anthony Michael Levenda Sep 2016

Configuring The Urban Smart Grid: Transitions, Experimentation, And Governance, Anthony Michael Levenda

Dissertations and Theses

In the face of challenges of energy security, decarbonization, resilience, and the replacement of aging infrastructure systems, federal, state, and local actors are facilitating the development of smart electricity networks to transition towards a more sustainable electricity system. In the United States, development of "smart grids" is being pursued as a national policy mandate and goal, promising that the deployment of smart grid technologies -- referring in general to digital information and communication technologies that sense, monitor, control and manage the electric grid -- will make electricity systems more environmentally sustainable and reliable, and at the same time, provide opportunities for growth ...


A Utility-Scale Deployment Project Of Behind-The-Meter Energy Storage For Use In Ancillary Services, Energy Resiliency, Grid Infrastructure Investment Deferment, And Demand-Response Integration, Joseph Nathanael Wilson Jun 2016

A Utility-Scale Deployment Project Of Behind-The-Meter Energy Storage For Use In Ancillary Services, Energy Resiliency, Grid Infrastructure Investment Deferment, And Demand-Response Integration, Joseph Nathanael Wilson

Dissertations and Theses

Electric utilities are increasingly incentivized to integrate new renewable energy generation resources to their systems; however, operations-related issues arise due to the non-dispatchable and stochastic nature of these renewable energy sources. These characteristics lead to a variety of issues for utilities, among which are voltage fluctuations, balancing dispatch against ramping events, short-duration power fluctuations, and the need to invest in peaking generation facilities just to accommodate the renewable energy. A traditional solution to these issues is to employ renewable generation-following techniques using either newly constructed gas peaking plants, or by shifting existing generation resources to this following responsibility. Unfortunately, use ...
