Abstract

An agent-based modeling approach is used to model changes in contracts at the retail level, in the context of a distribution grid model. The distribution grid model is based on the IEEE 13-bus test case and contract choice is modeled using a modified Roth-Erev algorithm. The model focuses on residential contracts, the least price-responsive sector of the distribution system, but how this approach can be extended to commercial and industrial sector customers is discussed. The modeling results indicate what parameters are important in the decision to change contracts, and these parameters can adjusted to calibrate the model to empirical data. The results show that with these contract changes, the system is more responsive to peak prices
