FICO Software Used in Power Scheduling Research

William Opalka

windpower_nrelResearchers at the California-based Lawrence Livermore National Laboratory (LLNL) are working  to determine the lowest-cost scheduling of electric power grids. They will include FICO’s Xpress Optimization Suite in their work. This is part of the Lab’s work on large-scale renewable energy integration, which is a subject of interest throughout the national research system.

LLNL is researching ways to determine which power generators to operate and how much power to produce at each generator to meet demand for a region at the lowest cost

The program is being used to solve problems at many time-scales, from long-term planning to day-ahead operations planning. The work involves solving the “stochastic unit commitment problem,” which attempts to capture the uncertainty in the system, including such weather components as temperature, wind speed, and cloud cover. This problem can be cast as a large-scale mixed integer linear program, to be solved on thousands of CPU cores in parallel.

The Catholic University of Louvain, Belgium is collaborating with laboratory on the energy problem. According to the university, FICO is used due to the integrated offering of a math programming language, Mosel, that can handle processor communication for parallel algorithms.

FICO’s Xpress Optimization Suite software is a platform for building optimization solutions that drive business process improvements. The company said the optimization suite provides ways to create, deploy and utilize business optimization solutions based on scalable high-performance algorithms, a flexible modeling environment, and rapid application and reporting capabilities for on premise and cloud installations.

  1. Dear Sir
    I am writing to amend your information on the applications of the XPRESS software for the commitment and dispatch in power systems. The first time this software was used in Poland in the balancing market in year 2000. The software was designed by prof. W. Mielczarski on the order of National Power Control Centre. It performs the commitment and dispatch of 110 power units for 24 hours what leads to mix integer programming of 2500 binary variables and over 70 000 real variables. The computer program operates under Linear Programing Dispatch (LPD) name collaborating with GMOS which is the system for network constraints representation. The software is in operation for over 13 years and the rules applied became a part of the Network Code. The system is described in http://www.mielczarski.neostrada.pl/Papers/Modern%20Commitment.pdf
    Currently, a research team from Lodz Technical University, prof. W. Mielczarski, dr B. Olek, dr M. Wierzbowski and W. Lyzwa (PhD student) his working with the eMix program based on XPRESS. It was constructed on the order of Ministry of Economy, Poland. The program eMix is dedicated for simulations of mix energy in a long term horizon taking into account energy and climate policies and various structures of electric energy and power generating capacity markets.
    Yours
