Strategies for operating refrigerated warehouses under real-time pricing.

Author(s) : STOECKLE R., REINDL D. T., MITCHELL J. W.

Summary

The availability of an energy storage medium allows the refrigeration system operation to be decoupled from the refrigeration loads. In cold storage warehouses, the stored products themselves have the potential for use as an energy storage medium. In the paper, the authors present a simple method that forecasts whether or not demand shifting the refrigeration system operation on a daily basis results in operating cost savings. The method includes predicting the maximum allowable floating duration based on the outside air temperatures for the next day and establishing the floating period that yields the greatest operating cost savings. A simple price ratio criterion was found to be a good indicator of energy cost savings by demand shifting.
