Derivation of Robust Storage Targets for Large-Scale Pumped Hydro Energy Storage using PLEXOS28 February 2013 by Energy Exemplar
This paper examines the modelling of large scale pumped hydro energy storage in future power systems where variable generation, primarily in the form of wind generation is the dominant source of power generation.
It is shown that current deterministic modelling techniques do not give a correct valuation to pumped hydro storage and can in cases overvalue the resource.
A methodology is proposed, using stochastic optimisation where historic wind data in conjunction with weekly wind energy forecasts are used to derive weekly and daily targets for storage reservoirs that are adequately robust to manage wind variability and uncertainty.
This is ongoing work and as such brief preliminary results are presented in this paper.
