High-Performance Computing Energizes Future Grid Efforts

October 2014

PNNL released version 2.0 of GridPACK™, a software framework designed to simplify the development of programs for simulating the power grid that can harness the capabilities of high-performance computing. GridPACK, or Grid Parallel Advanced Computational Kernels, is one of several software tools being developed at PNNL under the DOE Office of Electricity Delivery and Energy Reliability (DOE-OE) Advanced Grid Modeling program. GridPACK was started as part of PNNL’s transformative Future Power Grid Initiative (FPGI) before being fully funded by DOE.

Since GridPACK's initial release in November 2013, DOE-OE funding has enabled new features that include:

  • an interface that accommodates the popular Fortran programming language, broadening the base of potential users
  • two additional applications that demonstrate how GridPACK can be used to create parallel power grid simulations. These include a massive contingency analysis code that can assess the effect of different failures in the system, and a state estimation program, which informs operational decisions by assessing how the grid is operating at any point in time
  • modules and performance enhancements that support new types of calculations.

Continued investment by DOE in GridPACK over the next three years will support collaboration among other national laboratories to make additional high-performance libraries and algorithms available to the broader power grid community.

GridPACK is one of the components in FPGI's Grid Operation and Planning Technology Integrated Capabilities Suite (GridOPTICS™). GridOPTICS tools are designed to securely collect and manage grid data in real time, use data to drive modeling and simulation, and convert large volumes of data to actionable information – in support of grid operational and policy decision-making.
