This thermal energy storage system (tess) class describes a system of one or more [thermal energy storage units]ThermalEnergyStorage-Class) (tes).

Input Variables

tesIDS: A list of integers for identification of the tes that make up this tess.

tesT: A list of initial temperatures in Kelvin of the tes units.

tesStates: An integer list of the initial operating states, 0 - off, 1 - starting, 2 - online.

timeStep: The length of the simulation steps in seconds.

tesDescriptors: A list of thermal energy storage descriptor XML files for the respective tes units listed in tesIDS, this should be a string with a path and file name relative to the project folder, e.g., /InputData/Components/tes1Descriptor.xml.

tesDispatchFile: The path to the class that dispatches the thermal energy storage units in the grid. Options included in the software package are listed in tesDispatch. A user can also write their own class. It needs to follow the instructions listed in tesDispatch.

tesDispatchInputsFile: The path to the xml file that provides the inputs to the tesDispatch. A copy of this file is saved in the projectName/Setup/UserInput/ folder. If tesDispatch0 is used, the file name will change to projectNameTesDispatch0Inputs.py, for example, where projectName is the name of the project. If the user writes their own tesDispatch class, then they will need to create their own projectTesDispatchInput xml file as well.

Methods

runTesDispatch(self, newP): This runs the thermal energy storage Dispatch and then checks the operating conditions of each tes unit.

checkOperatingConditions(self): This checks if the tes is operating outside of its rated bounds.
