Title: Homeostatic utility controls applied to TVA: Final project report

Technical Report ·
OSTI ID:6147109

This project concerns a way for a utility to interact with its customers to achieve a better load profile. The customers are those who have some degrees of freedom as far as their load schedules are concerned. Such a customer, a Small Power Producing Facility (SPPF), may shift its demand during the day or may be selling energy back to the utility during parts of the day. The utility must provide incentives for the customer that ''help'' the utility load curve; these incentives are the energy rates. The fundamental question is how a particular SPPF will react to a set of selling and buying prices when it carries out an optimization of its own operation. Another problem is that of sizing, during the plant design stages, of some of the on-site SPPF facilities, such as the on-site energy storage capacity. This can be done once the energy selling and buying rates are set. These design oriented problems are of importance when a utility advises its customers as to what type and size of on-site installations are financially feasible. However, the only true ''control'' that the utility has over the SPPF is through the selling and buying of energy rates. It is of key importance to be able to determine a set of selling and buying energy rates which, while still within reasonable limits, ''induce'' the proper behavior by the SPPF to satisfy the utility desired constraints. The global impact of all SPPF's on the utility system has also been evaluated in this project. 46 refs., 19 figs., 48 tabs.
