Brookhaven Lab supports the Department of Energy/OE AGM program through the following projects.
Formal Analysis for Dynamic Stability Assessment
Brookhaven Lab has developed an innovative and tractable method for assessing the stability of both transmission and distribution systems in the power grid under uncertainties from heterogeneous sources, such as Distributed Energy Resources. Details...
Stochastic Sizing and Operation of Grid-Level Energy Storage Systems under Intermittent Renewable Generation and Increasing Load Forecasting Uncertainties
Brookhaven Lab has developed probabilistic sizing techniques for Energy Storage Systems (ESS) based on grid-inertia responses under high penetration of renewables, along with stochastic operation optimization techniques for ESSs that account for the intermittence of renewable generation. Details...
Risk-Informed Decision-Making Capability using Electric Power Industry Standard Planning Tools as a Platform
This project demonstrated the usefulness of probabilistic electric grid reliability metrics and the complementary enhancement of the deterministic counterpart considering various uncertainties, including those from renewable generation in the emerging probabilistic contingency analysis (PCA) for a large utility scale system.

Practical Quantum Analytics for Ultra-Efficient and Resilient Bulk Power Systems Operations
This project aims to develop practical and scalable quantum grid analytics (QGrid Analytics) to enable ultra-resilient bulk power system operations. An open-source QGrid Analytics Toolbox will be developed, which consists of efficient linear and non-linear quantum solvers and quantum consensus-based distributed algorithms for grid analytics.
A Deep Learning Based Online Platform for Critical Anomaly Detection and Emergency Control to Enhance Grid Reliability and Resiliency
The objective of this study is to develop a data-driven, deep learning-based solution to prevent the propagation of cascading failures when the grid is challenged by unexpected contingencies or combinational contingencies under uncertain environments. The proposed end-to-end technology will be an online platform capable of evaluating and predicting grid conditions and selecting emergency control actions focused on load shedding strategies and determination of timing and boundaries for splitting the grid into self-sustained islands, as needed, to mitigate the propagation of cascading failures.

Grid of the Near Future: Development of a New Framework for Modeling, Stability Analysis, and Control
This project will investigate and understand some of the fundamental issues the transitioning bulk power grid of the near future is facing and develop a new framework for modeling, stability analysis, and control to address these issues. The grid of the future is expected to be dominated by converter interfaced generation (CIGs) with some of the grid connected synchronous generators (SGs). Therefore, the “near future” grid of interest will be the one with comparable generation capacity of SGs, grid-following CIGs, and a small fraction of grid-forming CIGs. New issues are expected during this long transition and must be dealt with properly. The project will be carried out by developing (1) a modeling framework to account for dynamics of different time scales for SG and converter models to include SG stator transients, transmission line dynamics, and averaged model of the converters with inner and outer control loops, phase lock loops (PLLs), and DC-side dynamics with all limiting functions; (2) advanced control solutions for converters and two specific grid-forming technologies, i.e., droop control and matching control and for supporting the weak grid using the retired generators as synchronous condensers.
About DOE AGM Research
The electric power industry has undergone extensive changes over the past several decades and become substantially more complex, dynamic, and uncertain, as new market rules, regulatory policies, and technologies have been adopted. As the electric delivery system continues to evolve, the availability of more detailed data about system conditions from devices such as phasor measurement units (PMUs) used for wide area visibility and advanced meter infrastructure (AMI) used for dynamic pricing and demand response will help improve the system’s reliability and flexibility.
Working with the large volume and variety of data to make it more relevant and actionable to grid operators and utilities, however, poses significant challenges. Continuing to shift operational data analytics from a traditionally off-line environment to further expand real-time situational awareness of grid conditions and measurement-based, faster control will require significant advancements in algorithms and computational approaches.

To address these challenges, DOE’s Office of Electricity (OE) Advanced Grid Modeling (AGM) Program sponsors research to:
- Support the transformation of data to enable preventative actions rather than reactive responses to changes in grid conditions;
- Direct the research and development of advanced computational and control technologies to improve the reliability, resiliency, security, and flexibility of the nation’s electricity system;
- Help system operators and utilities prevent blackouts and improve reliability by expanding wide-area real-time visibility into the conditions of the grid
- Support improvement of the performance of modeling tools and computations that are basis of the grid operations and planning; and
- Support the tracking and expansion of the use of quantitative risk and uncertainty methods by federal and state level energy system decision makers regarding energy infrastructure investments.
