[TRNSYS-users] type94

[Diego A. Arias]

Hi,

You can think of Type48 as a controller for the simulation with a pv 
module and battery storage. The easiest way to simulate a system with a 
PV module and a battery is to use Type48b (Regulator and inverter/system 
with battery storage/maximum point tracking/ state of charge (SOC) 
monitoring) and Type47c (Batteries/Power as input/Shepherd modified 
Hyman Equation), as they only exchange information regarding power.

 From PV panel to Type48:
- If you are using a maximum power tracker, connect the maximum power 
from the PV panel Type 48's input 1. If you are using a different load 
curve, connect the power output from the PV instead.

 From Loads to Type48:
- If you used Type14 to define your hourly loads, connect it to Type 
48's input 2.

Type48 to Type 47:
- Output 2 (power to or from battery) --> Input 1 (Power to or from battery)

Type47 to Type48:
- Output 2 (fractional state of charge) --> Input 3 (Battery fractional 
state of charge)

These two connections between Type47 and Type48 will make TRNSYS to 
iterate until it reaches a solution.  You may find that you need a short 
time step to reach a converged solutions at each time step. I used 0.25h 
and it seemed to work fine.

I will be glad to hear other solutions. Please let me know if you have 
more questions.
Best regards,

Diego
