To determine how to represent a system state / system states, one should consider the following questions regarding the operation rules:
Subject |
Questions about real-world operating rule |
Questions about Talsim-NG river basin model |
Implementation in Talsim-NG |
|---|---|---|---|
Measured variable |
Which measured variables are the operating rules based on? Which variables are measured? |
Which is the equivalent simulated variable, or which simulated variable could be used for reference / derivation? All simulated variables i.e. the system element's input, output, and state variables are generally accessible (e.g. discharge, storage volume, ...). |
Choose a system element and a simulated variable. → Implement a system state. |
Spatial reference |
Which location is the measurement made at? |
Which specific system element (key) represents the measurement (with which simulated variable for the system state)? |
|
Temporal reference |
What is the temporal reference of the measurement? Is the instantaneous value used, a balance, or a previous day's value? |
Which of the available options in Talsim-NG represents the temporal reference best? |
Define the objective of the system state and adjust the options for value changes respectively. |
Transformation |
Is the measured value changed subsequently before its inclusion in the operating rule (e.g. unit conversion, weighting function, ...)? |
Which function in Talsim-NG represents the transformation? |
Select and implement the transformation function of the system state. |
