Two new preliminary component types were developed for the transient simulation program TRNSYS with IISiBat that models three different types of sensible thermal storages for analysis with use in a solar electric generating system (SEGS) simulation. One component containing a fully mixed, a stratified and a plug flow tank model options has been developed such that the input and parameter specifications are similar so that all three models could be easily placed into one component type. A single, cylindrical direct storage tank with one inlet and one outlet that evaluates fluid properties as a function of temperature is representative for all three models. The second component is a storage controller that passes along pertinent charging, dwell or discharging information to the storage and integrates the storage into a given SEGS model. Results were generated for each storage tank integrated into a SEGS VI simulation model for temperature distribution and power generation.
