Area Information: OPF
The OPF Tab contains information regarding the Optimal Power Flow (OPF) solution data for an area. It houses the following information:
Average LMP for Area
The computed average locational marginal price of all buses contained in the area.
LMP Standard Deviation
The standard deviation of the locational marginal price for all buses contained in the area.
Min/Max LMP
The minimum and maximum locational marginal price of all the buses in the area.
Total Generator Production Cost (Scaled)
The scaled cost includes the Cost Shift and Cost Multiplier. These two values can be defined for each generator, and allow the user a way to assess changes to the LMP results when a generators cost or "bid" is modified, without actually changing the original generator cost or bid curve. The scaled cost function for each generator is equal to:
(original cost function + cost shift) * cost multiplier
Total Generator Unscaled Production Cost
The total unscaled generator production cost, based on the original generator cost or bid curves.
Total Generator LMP Profit
The profit of the generators in the area based on the Locational Marginal Prices (LMPs) determined by the OPF solution. The profit is determined as:
LMP Price * MW Output – Unscaled Cost Function
Cost of Energy, Loss, and Congestion Reference
Specify a reference for determining the cost of energy, loss and congestion. The choices are Existing loss sensitivities directly, Area’s Bus’ Loads, Injection Group, or a specific bus.
Reserve Requirement Curves
These options are only available with the OPF Reserves add-on. More information about these options can be found in the Area and Zone OPF Reserve Requirement Curves topic.
