SCOPF Bus Marginal Price Details
This display (from the SCOPF Results page) shows information about the components of the marginal
cost at each bus. The display is relevant to see how the bus marginal cost depends on the cost of
enforcing system constraints such as branch limits and area equality constraints. This display is useful
for indicating which constraints are contributing towards the determination of the marginal price at
each bus.
As any case info display in Simulator this display can be customized and the information copied,
printed, and saved by accessing the local menu option with the mouse right click.
One key feature of this display is the breakdown in the bus MW marginal cost into three components:
the cost of energy, the cost of congestion, and the cost of losses. Also, while the bus MW marginal
cost does not change based on the reference, the costs of energy, congestion, and losses are
reference dependent. This reference is set on a per-area (or per-super area) basis in the Area
information dialog OPF tab (or the Super Area information dialog OPF tab).
