Interval Reporting

Interface Flow, in reporting by interval, is the net flow on the interface, or:

\begin{matrix} Interface Flow = & \sum Lines (Flow Coefficient \times Line Flow + Flow Forward Coefficient \times max (0, Line Flow) + Flow Back Coefficient \times Line Flow Back) + \sum Tranformers Flow Coefficient \times Transformer Flow \end{matrix}

$\begin{align} \text{Interface Flow } =& \sum_{\text{Lines}} \Big( \text{Flow Coefficient} \times \text{Line Flow} + \text{Flow Forward Coefficient} \times \max(0,\text{Line Flow}) \\ &+ \text{Flow Back Coefficient} \times \text{Line Flow Back} \Big) + \sum_{\text{Tranformers}} \text{Flow Coefficient} \times \text{Transformer Flow} \end{align}$

This sum shows both net and directed Line Flow terms. In practice, the interface would use just one set of Line flow coefficients.

Summary Reporting

In reporting summary values (day, week, etc), Flow is defined as the sum of flows in the reference direction and Flow Back is the total flow in the counter-reference direction,
