Coupling hydro-power to the grid

Note

A hydro power module in the market model can also have been left out of the EFI-PROD-1 and EFI-PROD-2 files, either by mistake or because there is no hydropower plant at this module. Any production at these modules is subtracted from the area firm load.

In case of a module being a pump, the power used for pumping is subtracted from the power injection at that busbar.

In the case of a share equal to 0 for all defined busbars it is assumed an equal share.

For each step, all busbar weights are accumulated and relative shares for each busbar are computed. If the same busbar is listed several times, its weights are accumulated.

Selected hydro-power modules are connected to the grid busbars in EFI-PROD-1.DAT. Only hydro-power modules connected to one (1!) busbars are specified her. If a hydro-power modules is connected to more than one busbar use EFI-PROD-2.DAT. Note that a busbar can be connected to several hydropower modules.

One hydro-power module number connected to multiple busbars

Header hydropower module

Record format:

<Hydropower module number>, <Number of busbars>,

Example:

The hydropower module 7001 is connected to two busbars

7001,   2,    # Hydropower module number, Number of busbar connections

Connected busbars

Record format:

<Busbar number>, <Weight or share of power production>,

Example:
