The GROW-DERS project (Grid Reliability and Operability with Distributed Generation using Flexible Storage), funded by the European Commission, aims to solve the technical challenges associated with distributed energy resources by using transportable and flexible storage systems. This paper discusses how recent developments in Li-ion batteries, flywheels and power electronics can be applied to use electricity storage systems in such a way that they manage the energy grid. These technologies are used in a number of demonstration test sites across Europe. In the demonstration test sites the technical feasibility is proven. The project also examines a technical-economic software assessment tool that is being developed to optimise the location, type and size of storage systems for distribution grid applications.
