Abstract
A general, standard device model with a battery equivalent interface applicable to commercial refrigeration system was developed in this study. The main characteristics of this proposed device model include: 1. it is simple and generic to use with only a single, simple dispatch algorithm for each grid service, rather than a custom algorithm, 2. it can be used for the tools used to plan and design new and modernized grid infrastructure, and to operate transmission- and distribution-level grid management/control systems and markets, so they can properly represent the roles and functions of DERs in the future grid, 3. it is a unified modeling approach for evaluating the performance of grid services. Along with the commercial refrigeration system standard device model development, the commercial refrigeration system characterization protocols are developed and tested to measure the parameters defined by the commercial refrigeration system models and provide evidence of the adequacy and accuracy of the commercial refrigeration system models and battery equivalent interface.
