I am trying to figure out the efficiency of a reversible hydraulic generator/pump station that will generate electricity when the price is high, and pump water up into the reservouar with power from the grid when electricity is cheap.
I have calculated the following information for the pump and turbine:
Ppump= 10 MW
Qpump= 7.5 m^3/s
Pturbine= 96 MW
Qturbine= 72.5 m^3/s
How can I figure out what percentage of the bought energy can be delivered back to the net?
I am having trouble figuring out how to set up an equation I can use to solve this problem, No matter what I go I get really high effeciency like 99% which must be wrong.
Thanks in advance.
