Smart Power Flow

Project period 01.08.2013 - 31.07.2016

Relieve the distribution network

In this project for the first time of a large scale stationary redox-flow battery (CellCube FB200-400 DC) of the company Gildemeister energy solutions will be integrated into a distribution grid in order to reinforce an electrical network with a high share of renewable energies. The main aim is to quantify which and in what amount network expansion measures can be avoided through the usage of battery storage systems.

Analysis and optimization

The main objectives of the project are the technical and economic analysis and optimization of network expansions and usage of local energy storage systems. As part of the project a redox-flow storage of the company Gildemeister energy solutions will be integrated into the distribution network and adapted to a new demand profile, due to the rapid increase in the use of renewal energies. The most important intermediate steps are: Identification of network characteristics for achieving an effective optimization of network expansion versus the implementation of decentralized energy storage systems; Development of battery inverters for 200 kW DC / 500kVA redox-flow batteries; Demonstration and confirmation of the analytically identified network optimization measures.

In the SmartPowerFlow project a simulation will be developed to determine the optimal placement of big stationary batteries within distribution grids with high shares of reneable energies. The aim of the model is to facilitate a wide scale mentation of stationary batteries into the German electrical grid.

Realization in three steps

Phase 1: Optimization of the location of a redox flow battery in the grid of the DSO LVN (LEW Verteilnetz GmbH) by using simulation tools; development of a battery inverter (first year)

Phase 2: Integration of the battery into the grid of LVN and validation of the simulation modells using measured data (second year)

Phase 3: Development of a concept for the integration of large battery storage systems into distribution grids; technical and economical evaluation of grid extension versus integration of battery systems into the distribution grid (third year).
