Linear Economic Value
NoneNo evaluation is made.
Calculate Linear Economic ValueThis method applies a time dependent linear value to power generated. This method is also known as POSE or System Lambda. The order of power source evaluation doesn’t matter, only which power sources are being evaluated, because of the linear valuation. In general, the calculation is a simplified version of the existing block calculation. The value of hydropower is in the Linear Hydro Costs series slot.
The power sources to use in the evaluation are selected in the Linear Power Sources Used table slot. The possible power sources are conventional hydropower, pumped storage, and allocated power. The calculated value of each type of power is output to a corresponding series slot.
Allocated power is constrained by minimal and maximal power generation for each time period combined with periodic total energy requirements. The power is allocated for maximal economic gain in coordination with other power sources.
After calculating the individual economic components for each time period, the totals for all time periods are placed in the Linear Total Values table slot.

Allocated Total Energy
Type: Agg Series Slot
Units: Energy
Description: Total energy to be allocated from a project over some time period.
Information: One column for each project to be allocated. Totals should be entered with some consistent period. For example, values entered only once a day will be allocated across that day assuming the model has a timestep smaller than one day.
