Increasing Wind Energy Penetration Level by Using Pumped Hydro Storage in Island Micro-Grid System

Wind powered pumped hydro storage systems, a means of increasing the penetration of renewable energy in the Canary Islands

A significant number of islands have found themselves obliged to place restrictions on the penetration of renewable sourced energy in their conventional electrical grid systems. In general, this has been due to certain energy related characteristics often connected to their very nature as islands. These limitations attempt to prevent the appearance of problems that might affect the stability an...

Feasibility Study of Pumped Hydro Energy Storage for Ramea Wind-Diesel Hybrid Power System

INTRODUCTION OF BATTERY ENERGY STORAGE IN A SMALL ISLAND GRID TO INCREASE WIND ENERGY PENETRATION LEVELS K.Papastamoulos,

In small autonomous island systems, such as those in the Aegean Sea, Greece, the load is covered by diesel engines. Technical constraints of the conventional generating units keep RES penetration in these islands at low levels. To overcome such limitations, in the case of small island systems (peak power less than 1 MW) battery energy storage appears today as an attractive solution from a techn...

Pumped Storage in Systems with Very High Wind Penetration

This paper examines the operation of the Irish power system with very high levels of wind energy, with and without pumped storage. A unit commitment model which accounts for the uncertainty in wind power is used. It is shown that as wind penetration increases, the optimal operation of storage depends on wind output as well as load. The main benefit from storage is shown to be a decrease in wind...

The contribution of wind-hydro pumped storage systems in meeting Turkey’s electric energy demand

Renewable energy resources have played an important role to meet increasing energy demand in the world. Among the renewable energy resources, especially, wind energy is of interest due to some advantages, such as being clean, environmental friendly etc. However, the intermittent nature of wind creates several problems to the power system operation and new approaches based on the combined use of...
