Title: Factored Customer Model
Author: Prashant Reddy Contact: [email protected]
Description: This plugin contains a "Factored Behaviors" statistical model of customer populations with consumption and/or production capacities. Behaviors such as tariff-utility, tariff-switching-inertia and elasticity-of-capacity can be specified directly using probability distributions, or alternately, they can be computed by the model using specified factors which underlie those behaviors (not fully implemented yet).
