Climate Change Impacts in the Assured Energy of the Brazilian Power Generation System

Funded by Brazilian Electricity Regulation Agency (ANEEL) Strategic R&D Project, 2011-2014

The goal of this project is to evaluate possible climate change effects in the Brazilian hydropower systems. We aim to evaluate results of the climate projections from the 4th report of the Intergovernamental Pannel on Climate Change (IPCC) and their association with future water inflows in all the major water basins in the country. An interaction among regional climate, water inflows modeling, and optimal dispatch is considered in this work assessing potential impacts for the Brazilian hydropower system.

Refinement of the FREEDM Center Cost-Benefit Model

Funded by NCSU Future Renewable Electric Energy Delivery and Management Systems Center (FREEDM), 2016-2017

The goal of this project is to perform a benefit comparison between competing technologies with respect to cost and performance of alternatives as well as simulations of FREEDM and alternatives in OpenDSS.

Diversifying Investments in NC Offshore Renewable Energy Technologies

Funded by NC Renewable Ocean Energy Program (NCROEP), 2017-2018

The goal of this project is to identify optimal resource portfolios that consider multiple offshore renewable energy sources. To achieve this goal, we will enhance the portfolio optimization framework we developed during the previous fiscal year and apply it to multiple offshore renewable sources off the North Carolina coast, including offshore wind, wave, and Gulf Stream current energy.

A Proposed Energy Storage Study for North Carolina

Funded by UNC Policy Collaboratory, 2017-2018

The objective of this project is to generate an analysis of the economics of energy storage devices in the state of North Carolina that provides clear policy guidance to the NC General Assembly, NC Utilities Commission, and the NC Energy Policy Council, informed by stakeholder engagement and the application of open and transparent modeling tools.

Collaborative Research: NSF-NSFC: Improving FEW system sustainability over the SEUS and NCP: A cross-regional synthesis considering uncertainties in climate and regional development

Funded by National Science Foundation (NSF), 2018-2023

The overarching research question of this proposal is to understand the potential effects of uncertain climate and FEW development scenarios (i.e., policy and demand changes) on the sustainability of regional Food Energy and Water (FEW) system. Given the FEW interdependency complexities, we consider as study regions the Southeast US and North China Plain, that are large enough to capture the cascading impacts across the three systems from both the US and China. In that way, local/regional climatic impacts or policy changes on any of the FEW systems could be used to understand the impacts on the regional FEW systems.

Optimizing Investments in Offshore Renewable Energy in the North Carolina Electric Sector

Funded by NC Renewable Ocean Energy Program (NCROEP), 2019-2020

The goal of this project is to conduct portfolio optimization analysis of renewable energy resources using hourly data and identify the most promising site locations and generating technologies for the North Carolina coast. We will integrate the optimal offshore energy portfolio into our open source capacity expansion model of the NC electric sector and evaluate the cost-effectiveness of offshore energy in the state. Such systems-level economic analysis of offshore energy in North Carolina provides critical information to third party developers, electric utilities, and electricity cooperatives.

Analyzing Investments in NC Offshore Renewable Energy Under Uncertain Resource Availability and Hurricane Damages

Funded by NC Renewable Ocean Energy Program (NCROEP), 2020-2021

The goal of this project is to quantify the risk of low probability, high impact events associated with low offshore energy production and the risk of hurricane damage. Such systems-level economic analysis of offshore energy in North Carolina has never been done and will provide critical information to third-party developers, electric utilities, and electricity cooperatives. The consideration of these low probability, high impact events can provide critical insights that affect the selection of optimal offshore energy portfolios in North Carolina.

Assessing the Risk of Hurricane Damage to Marine Hydrokinetic Devices

Funded by NC Renewable Ocean Energy Program (NCROEP), 2021-2022

The goal of this project is to rigorously analyze the vulnerability and potential consequences of hurricane damage to wave and ocean current devices located off the North Carolina coast. The analysis of extreme events in the context of marine renewable energy is of critical importance to the future deployment of these technologies in North Carolina.

A Data-Driven Risk-Based Enterprise for Operational Decision Support

Funded by Department of Homeland Security - Center of Excellence on Cross-Border Threat Screening and Supply Chain Defense, 2021-2023

This project seeks to mitigate the risks of transboundary pest and disease threats (TPDT’s) by developing data integration and forecasting methods that improve decisions about the presence of possible TPDT’s before they reach our ports of entry. This project will develop and use artificial intelligence algorithms that learn, adapt, and evolve to improve decisions to aimed at detecting suspect imports and, therefore, preventing the introduction of TPDT’s in the U.S.

Mooring System Analysis and Fragility Curve Estimation: The Economic Impact of Low Probability High Impact Events on Ocean Current Devices

Funded by NC Renewable Ocean Energy Program (NCROEP), 2022-2023

In this project, we aim to improve the modeling/analysis of the mooring systems for ocean current devices and propose a fragility curve design capable of representing the most critical conditions for this technology. In addition, an aligned goal is to integrate the fragility analyses into a capacity expansion model of the NC energy system to make an economic assessment of the impact of these mooring fragility during operating conditions.

Fused Portfolio, Site, and Device Sizing Optimization for Harnessing North Carolina’s Coastal Renewable Energy Resources

Funded by NC Renewable Ocean Energy Program (NCROEP), 2022-2023

The objective of this project is to create an integrated framework that fuses (i) site selection, (ii) number of each type of device at each site, and (iii) device sizing sub-problems into a single tool, simultaneously accounting for the resource models, technical performance models, and cost models. The proposed work will lie at the intersection of two stated interests of the NCROEP, namely (i) resource assessment (via synthetic resource modeling) and (ii) device efficiency improvement (via optimization). In developing the aforementioned integrated tool, our team will build upon independent resource modeling, portfolio optimization, and device performance analysis to create a nested integrated optimization framework.
