Advanced Grid Modeling

Advanced Grid Modeling Research Program

The Office of Electricity's (OE) Advanced Grid Modeling program supports building capacity and capability within the electric sector to analyze the electricity delivery system using Big Data, advanced mathematical theory, and high-performance computing to assess the current state of the gird, mitigate reliability risks, and understand future needs. Berkeley Lab is one of the National Labs contributing to this program through the projects described below.

Current Projects

Block-level Approach for Risk Mitigation in Electricity Networks

Berkley Lab is developing an innovative bottom-up risk-controlled methodology for distribution system planning to reduce the uncertainty "seen" from the transmission-grid. This methodology will help utilities and regulators understand how distribution grid investments in DERs can decrease the long-term uncertainty in peak load at the substation and, therefore, decrease the need for transmission capacity. By structuring utility investments into blocks of risk mitigation, bottom-up uncertainty control options are provided while guaranteeing network operational constraints.

Modeling Decision Dependent Ambiguous Uncertainty in Power Systems

A stable and resilient operation of the power system requires a comprehensive framework to help the industry make decisions under uncertain grid conditions. In real applications, this uncertainty is difficult to characterize (ambiguous) due to lack of data or the uncertainty characteristics depend on decisions from the system operator. This project is developing a foundational mathematical framework to handle these complex aspects of real-life uncertainty in power systems and help utilities and ISOs make better risk-informed decisions regarding planning and operation of the grid.

Advanced ISO Models for Storage and Hybrid Resources Operation

 

This research addresses key modeling challenges that ISOs/RTOs and the software industry are currently facing in representing energy storage resources in day-ahead and real-time operations that can be easily integrated with existing systems in the next couple years. The modeling challenges and solutions proposed by the project team are informed by industry feedback through a recurrent engagement with ISOs/RTOs and the storage industry. The objective is to produce analyses and models that can support decisions around storage operation in bulk power systems.

Decision Support Tool to Estimate the Cost of Climate-Related Impacts and the Value of Resilience Investments in the Electricity Sector

Berkeley Lab is assisting the further development of an online decision-support tool for utilities to assess their resilience posture. The tool can help identify projected future climate impacts of concern across a utility service territory and then evaluate the economic justification for adaption action. Berkeley Lab research will be integrated into the Climate Risk and Resilience Portal (ClimmRR), a FEMA-sponsored online data and decision-support tool originally developed by Argonne National Lab. 

 

Past Projects

Risk-controlled Expansion and Planning with Distributed Resources (REPAIR)

The Risk-controlled Expansion Planning with Distributed Resources (REPAIR), developed by Lawrence Berkeley National Lab, is an innovative tool to support decisions around utility grid planning to prevent and mitigate the impact of outages caused by routine equipment failures (reliability) or by extreme events (resilience), such as storms, earthquakes or wildfires that long term interruption of service.

Scientific Machine Learning for Simulation and Control in Large Scale Power Systems

This project aims to develop new tools at the intersection of scientific machine learning (SciML) and power systems engineering. These tools will accelerate the simulation of power systems with high penetration of power electronic converters (PECs), to ensure that we can simulate these systems in near-real time. This acceleration will be achieved by 1) using SciML to develop accurate models of aggregations of PECs in order to reduce the number of equations we need to solve and 2) using SciML to improve the mathematical techniques we use for solving these equations.
