Control of Ice Storage model with Heat Exchanger

edit

I've been struggling with my ice storage model for a long time, and I've referred to previous posts, but I can't get it to work as expected, so I'd like to ask you how to solve the problems.

Below is a schematic diagram of plant loop and condenser loop of my model. The IDF file is here. Its version is v8.9.0. BrineChiller + IceTank is the main plant system, and BackupChiller is only for assisting when the IceTank is completely discharged and there is still cooling load.

There are two major fatal problems with my current model.

• Problem 1: ThermalStorage:Ice:Detailed doesn't charge nor discharge at all.
• Problem 2: Operation Status of HeatExchanger:FluidToFluid is always 0 (off).

About Problem 1, as some previous posts suggest, it seems that we have to use EMS to make the ice storage model work properly. None of ExampleFiles for ice storage model work properly. The charts below are part of the results of the ExampleFiles (they are not the results of my model).

I referred to one thesis “Strategic control and cost optimization of thermal energy storage in buildings using EnergyPlus” and tried to control charge/discharge of Ice Storage in my model based on Ice Thermal Storage End Fraction, but so far it's not working. I'm new to EMS and I think there's something wrong with it. Below is my input to EMS. Now I'm using only On/Off Supervisory. This control type doesn't have the function to force equipment to run. It can only run equipment normally based on other controls. I don't know how to force the Ice Storage to charge/discharge.
