Set binding constraints¶

To add additional constraints on your study that are not already implemented in Antares, you can specify some binding constraints. It is a linear combination of generation on clusters or on transmission in links that are bounded with a constant such as for each step \(t\):

\[ \sum_i w_i a_{t-o_i} \text{ bounded by } c_t \]

where:

\(w_i\) is a scalar weight
\(\text{bounded by}\) corresponds to the operators \(=\), \(<\), \(>\) or \(\neq\)
\(o_i\) is an offset in the time step
\(t\) corresponds to the considered time step which can be hourly, daily or weekly
\(c_t\) is the right hand side of the constraint a scalar
\(a_{t - o_i}\) corresponds to the cluster or link term

Left hand side¶

First, you need to create a new binding constraint in the Modeling > Binding constraints tab by clicking on the Add button in the left panel.

Then, give it a name, a type (whether this constraint is on hourly, daily or weekly time step) and a bound.

You will then have a similar view:

You have to create your linear combination corresponding to the left hand side of the constraint. Set the weights, term (link or cluster), time offset.

By choosing a link term, you want to constraint the transmission of the link between two areas (directional link). By choosing a cluster term, you want to contraint the generation of a cluster inside an area.

Right hand side¶

The right hand side of the constraint consisting of a column of values \((c_t)\). You can add these in the Time series tab.

Note

The length of this column depends on the time step of the binding constraints.
