The Linearized DC Model Revisited Again

Pascal Van Hentenryck

The linearized DC model has become a ubiquitous tool in electrical power systems, especially in planning and operational settings. In recent years, it has been used in an increasing number of applications, including line switching, power restoration, and vulnerability analysis. However, there is a lack of understanding regarding the accuracy and feasibilty of its solutions in these contexts. This talk presents a systematic analysis of the linearized DC model and proposes a number of techniques to overcome its limitations. In particular, the talk shows how to use smart load and generation scheduling to compensate for its inaccuracies in power restoration applications. It also shows how to approximate line losses and apparent power in cold- and hot-start models. Experimental results on standard IEEE benchmarks and on power restoration benchmarks using the infrastructure of the United States demonstrate the benefits and practicability of the proposed enhancements.
