ENERGY STORAGE TECHNOLOGIES FOR GRIDS WITH HIGH PENETRATION OF RENEWABLE ENERGIES AND FOR GRID CONNECTED PV SYSTEMS

摘要

Fluctuating power generation from renewable energies such as wind and photovoltaic are a technical challenge for the grid stability. Storage systems are an option to stabilise the grid and to maximise the utilisation factors of renewable power generators. This paper analyses the state of the art of storage technologies including a detailed life cycle cost comparison. Beside this, benefits of using storage systems in electric vehicles or private-owned PV systems are analysed and quantified. A comprehensive overview on storage technologies as well as possible applications and business cases for storage systems is presented.
