Distribution System Modeling with GridLAB-D

Overview

Gridworks is partnering with Stanford National Accelerator Laboratory (SLAC), Hitachi, National Grid, and the Pacific Northwest National Lab (PNNL) leading three CEC EPIC projects to develop distribution system modeling tools to evaluate distributed energy resources.

Modeling software for power systems is undergoing significant development to address an increasingly complex electric grid. This initiative looks to address some of these most pressing needs by enhancing GridLAB-D, an open source distribution simulation and analysis modeling software developed by the U.S. Department of Energy. GridLAB-D is capable of dynamic analysis, estimation of the grid benefits and impacts of DERs, and support of decision making and planning processes on the distribution system.

This initiative looks to enhance GridLAB-D through three discrete projects, developing:

  1. An open source modeling framework and translation tool;
  2. High-performance computing in open source grid modeling; and
  3. An open source user interface for GridLAB-D.

 

Open Framework for Integrated Data Operations (OpenFIDO) is a data interchange, synthesis and analysis framework allowing interoperability between different power systems tools. This capability allows for a more reliable and efficient data exchange.

High-Performance Agent-Based Simulation using GridLAB-D (HiPAS GridLAB-D) is an open-source upgrade to GridLAB-D that speeds up the analysis performance and computational efficiency of the tool, using intelligent, adaptive multi-threading to deploy highly granular parallelization in agent-based simulations.

GridLAB-D Open Workspace (GLOW) looks to develop a high-end user interface for GridLAB-D that is more intuitive and user-friendly for all stakeholders, including non-expert users, to increase access to simulation and modeling results.

Workshop 2–OpenFIDO: Open Framework for Integrated Data Operations

An open-source tool to support distribution-level data exchange on the electric grid 

SLAC National Accelerator Laboratory

 

Meeting objective:  Information sharing and introduction to OpenFIDO

Meeting Agenda:


1:00 – 1:40   Open FIDO Presentation by SLAC, explaining the following tools. 

    • CYME Data extraction 
    • Integration Capacity Analysis (ICA) for California 
    • GridLAB-D output conversion Analysis 
    • Grid Integration

    1:40 – 2:00   Q&A session 

    Description: 

    OpenFIDO is a data interchange, synthesis and analysis framework that provides information exchange between different power systems tools such as CYME, GridLAB-D, OpenDSS, Opal-RT and RTDS. The tool is used to transfer models and telemetry data between various tools that are part of the suite of tools widely used by utilities, distributed energy resource (DER) engineers, and regulators in California. The tool is designed for utility planners and grid researchers that need a tool and integration framework to quickly move data from one application to another as part of their engineering, planning, and review activities. The tool also supports emerging user groups such as DER system integrators and aggregators that use multiple tools to limit the grid impacts of DERs, as well as governments and agencies that use these models in both their oversight role and identifying opportunities for clean energy deployments.

    Friday

    The next GridLAB-D Technical Advisory Committee meeting has been scheduled for September 11, 2020, from 9:00, am - 12:00 pm.

    This meeting will provide an update on the development of the CEC’s GridLAB-D program, a distribution system modeling tool to evaluate distributed energy resources, including a live demonstration of the graphical user interface (GLOW).

    This will be a virtual event.

    Meeting Objectives:

    • Presentation of the prototype user interface GLOW and added capabilities of using GridLAB-D to analyze distributed energy resources  
    • Update the committee in the newer GridLAB-D capabilities. Machine learning power flow, development integration and electrification, tariff design and/or resilience use-cases.
    • Technical Advisory Committee feedback
