The role of district heating in energy systems with early natural gas phase‑out
presenter: Bilal Siddique
description: Very high natural gas prices last year due to the Ukraine-Russia war renewed calls for earlier natural gas phase-out. On the demand side, more ambitious energy renovation targets were proposed to reduce the energy demand. We look at these two important policy scenarios (earlier natural gas phase-out and energy renovation) from an energy system perspective and study the role district heating can play under this new reality on top of already established targets for zero carbon emissions by 2050. In this study, we use the energy system model BALMOREL, which has a comprehensive representation of the heating sector along with the power sector.

The Open Grid Emissions Initiative (OGE): Hourly, plant-level data for the entire U.S. power system
presenter: Greg Miller (Singularity Energy)
description: Published in 2022, the open-source Open Grid Emissions Initiative was the first comprehensive, plant-level dataset of hourly-resolution generation, fuel consumption, and direct CO2, NOx, and SO2 emissions for the entire U.S. power sector. In this talk, we will share how we built on existing OS projects like PUDL, the innovations that enabled the dataset to be created, and the insights we gained into how several of the assumptions implicit in the use of existing power sector emissions datasets may under-count or misrepresent the climate and health impacts of air emissions from the U.S. power sector. We envision the Initiative becoming a central repository of, and hub of activity for addressing open research questions related to power sector emissions data, and the go-to source for high-quality, high-resolution data for future research on U.S. grid emissions.

Using PowerGenome as a common data source for the Model Intercomparison Project
presenter: Greg Schivley (Princeton University)
description: In the Model Intercomparison Project we use PowerGenome as the common data source for the open-source capacity expansion models GenX, Switch, TEMOA, and USENSYS. Previous research comparing the results of capacity expansion models used simplified inputs that were not designed to represent a real-world scenario to isolate the parametric differences between each model. We have built translation layers so each model can use the same underlying data and designed a national 26-zone system to test a series of policy questions. Building translation layers from PowerGenome to different models will allow users to align model inputs and better assess the robustness of scenario results to differences in model structure. These translation layers will also serve as a starting point for anyone who wants to import data from PowerGenome for their own model.

A physics-informed data reconciliation framework for electricity and emissions tracking
presenter: Jacques de Chalendar (Stanford)
description: Using real-world data from the electricity system is challenging for quantitative applications requiring high quality and physically consistent data. Ad-hoc, manual data cleaning strategies are typically needed to prepare the data. As a complement and alternative to existing techniques, we provide a physics-informed framework to greatly accelerate and automate data processing. A key component of this framework is an optimization program to minimize the data adjustments required to satisfy energy conservation equations. This method is demonstrated by applying it to the continental United States electricity network. We generate internally consistent electric system consumption, production, import, and export data and use them to generate the visualization at energy.stanford.edu/gridemissions. We hope these methods can also be useful to energy system modelers with similar data quality requirements for different applications.

Pathways to Carbon Neutrality in California
presenter: Josh Neutel (Stanford)
description: California has ambitious plans for net-zero emissions by 2045, however, the road to carbon neutrality is not quite clear. The goal of this work is to evaluate various decarbonization technologies/policies, illuminating the most effective, economical, and feasible pathways to net-zero. To do so, an economy-wide model DECAL (DECarbonize CALifornia) was built using the Low Emissions Analysis Platform (LEAP). We ran hundreds of scenarios in DECAL to learn about California’s path to net-zero, in this talk we share some of the most critical insights.
A combined gas-electric optimization scenario for California with focus on end‑use appliances as a decarbonization strategy
presenter: Mo Sodwatana (Stanford)

Powered by distributed (parallel) computing and high-performance numerical solvers, GridPACK offers several applications (power flow, dynamics simulation, contingency analysis, and dynamics security assessment) for fast simulation of electrical transmission systems. Recently, we have expanded GridPACK library with inverter based resource models, including WECC generic models and grid-forming inverters. In addition, GridPACK is also a framework to simplify the development of new applications on HPC platforms. To ease the development, GridPACK offers several building blocks such as setting up and distributing (partitioning) power grid networks, support for custom components on buses and branches, converting the network models to the corresponding algebraic equations, parallel routines for manipulating and solving large algebraic systems, and input and output modules. An overview of the GridPACK library and its capabilities will be discussed briefly.

Scalable Solutions to Massive Grid Planning Problems
presenter: Anthony Degleris (Stanford University)
description: Modern electricity grid planners consider a variety of objectives and stakeholders when studying how new generation, transmission, and storage investments will affect the grid in the presence of an uncontrolled, competitive electricity market. Multi-value expansion planning (MEP) studies like these can be used, for example, to identify grid investments that minimize emissions in a market without a carbon tax, or to maximize the profit of a portfolio of renewable investments and long-term energy contracts. Unfortunately, MEP problems are usually non-convex and extremely difficult to solve exactly for large real-world systems. Therefore, we introduce a class of fast stochastic implicit gradient-based methods that scale well to large networks and many scenarios. Our method is inspired by similar techniques in machine learning and can solve generic MEP problems for networks with thousands of nodes and hundreds of scenarios.

Offshore Wind and Wave Energy Can Reduce Total Installed Capacity Required in Zero Emissions Grids.
presenter: Natalia Gonzalez (UC San Diego)
description: As countries around the world race to decarbonize their power systems in an effort to mitigate climate change, the body of research analyzing paths to zero emissions electricity grids has substantially grown. Although many commercially available technologies are typically included in these studies, only a few of them have considered offshore wind and wave energy as contenders in future zero emissions grids. We model, for the first time, offshore wind and wave energy as independent technologies with the possibility of collocation in a power system capacity expansion model of the Western Interconnection with zero emissions by 2050 and a high geographical and temporal resolution. Our key contributions are to identify cost targets for offshore wind and wave energy to become cost effective, to observe a 17% of reduction in total installed capacity by 2050 when offshore wind and wave energy are fully deployed, and to show how total curtailment decreases as offshore wind increases its deployment.

Bridging Data Gaps: Early Challenges and Improved Representation of The Canadian Open Energy Model’s (CANOE) Transportation Sector
presenter: Felipe Rashid Zetter Salcedo (University of Toronto)
project leads: I. Daniel Posen, Heather MacLean
description: As the need for novel long-term decarbonization strategies grows, so does the ESM community. The US’s investment in publicly released energy and GHG models has allowed the modelling community to innovate and support decision-making. However, Canada’s circumstances are different. Currently, some of the data required to develop ESMs is unavailable or inaccessible, presenting challenges for its modelling community to thrive.
This lighting focuses on the early development challenges of the CANOE model, specifically in the transportation sector, based on the Temoa framework. As access to disaggregated cost and performance data at the spatial and technological level is insufficient, many Canadian researchers must rely on US data, presenting yet another representation challenge to model future transportation system scenarios that are reliable. We explore different modelling decisions made to address these issues at the early stages, how other models have tackled similar challenges, and which new methods could improve system representation, potentially mitigating the uncertainty introduced by non-Canadian data.

Open Software, More Voices, Better Plans: Unlocking the Potential of Stakeholder-Driven Modeling
description: Open software and data have the potential to create new opportunities for “stakeholder-driven modeling” in which a range of stakeholders directly contribute to and influence grid modeling outcomes. But to unlock the potential of stakeholder-driven modeling, we need alignment and awareness from the open modeling community of the needs of utility and non-utility stakeholders. Participants will learn the fundamentals of the “integrated resource planning” processes common throughout the United States and learn about the value of stakeholder-driven modeling through a recent RMI case study. Participants will identify current barriers facing the widespread adoption of stakeholder-driven modeling, and brainstorm how the open modeling community can make its own tools and data more used and useful to a diverse group of stakeholders.

Energy Modeling intersections with Earth Systems: Needs for Integration
description: There is an increasing focus on using a combination of energy system models paired with earth system models, chemical transport models, reduced form models, and other geophysical models. However, it is important that as we develop these side by side, we understand and communicate what data is available, and what outputs are necessary for us to best use data from one for the other. The hope is that this will be a discussion of model input/output needs on both sides.

Modeling Large Scale Transmission Systems AC and DC technology modeling
description: Transmission modeling in energy systems is a critical feature that spans applications in capacity expansion, congestion modeling and price forecasting. The inclusion of transmission constraints in production cost models can result in very large optimization problems that can be challenging to solve in practice and/or take significant memory footprints increasing the cost of compute. This session focuses on the modeling and compute challenges of including transmission and transmission constraints in production cost/market simulation tools and simple techniques to handle those challenges.
