Changing Testing and Simulations Needs for Grid Modernization

Kevin Tomsovic

Abstract

Power system analysis has long relied on large scale computer simulations for operation and planning of the grid. These simulations rely on a set of well-understood physical models and generally agreed upon simplifications, such as, the separation of transmission and distribution, ZIP models for aggregate loads, and so on. Recent trends in the grid requires a rethinking of the models and these underlying assumptions.  Grid changes include: (a) the increasing number of power electronic interfaced devices both for renewable resources and for new loads; (b) the emerging importance of the analysis of the communication network for understanding operations; (c) a more actively controlled distribution system; and (d)  new performance requirements for both reliability and resilience.  Their are competing approaches to this need ranging from fully integrated models to independent simulators that share minimal information. This talk will review our approach in the research center CURENT using both software and hardware environments.
