Currently, pumped storage plant s (PSPs) are the only mature large scale option to store energy and react flexible on system demand. The remaining optimization lever is cost of a PSP – beside other positions the machine Considering all revenue streams – wholesale market, ancillary services and portfolio effect
Why do pump-hydro energy storage plants have a short time horizon?
For short time horizons, the MPC attempts to maximize the revenue for that time interval by considering that it does not continue from the end of that horizon. For this reason, in the case of pump-hydro energy storage plants, the intervals of generating or consuming electricity are shorter than for larger horizons.
Why does a pumping water trough de turbine generate less electricity?
When the plant is pumping water, the necessary electrical power from the grid is greater than the power that actually moves the mass of water. Otherwise, when the plant is generating moving water trough de turbine, the electricity generated is less than ideal due to the same reason. 5. Revenue and Design of the Plant 5.1.
How does a PSH plant cost model work?
