TLDR
In this article, the authors discussed how a sustainable energy supply based on off-shore wind power and pumped storage, called a "wind and water"-model, might look, and it turns out that such an energy scheme, while feasible in principle, would require an immense storage capacity which would be impossible to realize.Abstract:
Sustainability of the future energy supply based on renewable resources is a long-term strategic objective in view of limited fossil resources and avoidance of emissions and toxic waste. Of the various resources, available now or in future, wind is presently considered in Europe to hold most promise in the next few decades for contributing a sizable part of the electrical energy; generating electricity from wind is state of the art and feeding large amounts of wind power to the electrical grid is believed by many to be unproblematic. With recent data from one of the four control areas in Germany it is discussed how a sustainable energy supply based on off-shore wind power and pumped storage, called a "wind and water"-model, might look. It turns out that such an energy scheme, while feasible in principle, would require an immense storage capacity which would be impossible to realize. Thermal generation continues to be needed, based on various energy carriers, among them biomass according to availabilityread more

Stochastic Joint Optimization of Wind Generation and Pumped-Storage Units in an Electricity Market
TL;DR: In this article, the authors investigated the combined optimization of a wind farm and a pumped-storage facility from the point of view of a generation company in a market environment, and formulated the optimization model as a two-stage stochastic programming problem with two random parameters: market prices and wind generation.

Optimal Allocation of ESS in Distribution Systems With a High Penetration of Wind Energy
Y.M. Atwa,Ehab F. El-Saadany +1 more
TL;DR: In this paper, the authors proposed a methodology for allocating an ESS in a distribution system with a high penetration of wind energy, aiming to maximize the benefits for both the DG owner and the utility by sizing the ESS to accommodate all amounts of spilled wind energy and by then allocating it within the system in order to minimize the annual cost of the electricity.

Comparing Hedging Methods for Wind Power: Using Pumped Storage Hydro Units vs. Options Purchasing
Kory W. Hedman,Gerald B. Sheblé +1 more
TL;DR: In this article, the authors analyze the option of using a pumped storage hydro plant to negate this uncertainty from a financial viewpoint and compare it to the case where the wind farm can purchase call/put options to protect against the uncertainty of the wind.

Auswirkungen des fluktuierenden Energieangebotes auf den Systembetrieb
TL;DR: The problem of fluctuating wind generation must not be considered as a task all by itself, because the liberalized energy market is still evolving while wind energy capacities are being expanded as mentioned in this paper.
