DABESI project: EDF Renewables and other industry players bundle know-how to optimise energy storage systems for industrial companies


Ber­lin, 05.05.2021 The pro­ject part­ners Ernst Knoll Fein­mech­anik GmbH, Fraunhofer ISE, Solan­deo GmbH, the BVES Bundes­verb­and Ener­giespeich­er Systeme e.V. (Fed­er­al Asso­ci­ation of Energy Stor­age Sys­tems) and EDF Dis­trib­uted Solu­tions GmbH are work­ing on solu­tions to improve the integ­ra­tion of energy stor­age sys­tems in industry in the BMWi-fun­ded DABESI” pro­ject. To this pur­pose, the dimen­sion­ing and oper­a­tion of dif­fer­ent stor­age tech­no­lo­gies are to be invest­ig­ated for rel­ev­ant applic­a­tions and the optim­ised use of these stor­age sys­tems in medi­um-sized indus­tri­al com­pan­ies, tak­ing into account com­pany-spe­cif­ic load profiles.

Stor­age solu­tions act­ively con­trib­ute to the energy transition

Energy stor­age sys­tems offer a vari­ety of options for improv­ing the integ­ra­tion of renew­able power gen­er­a­tion into the energy sys­tem and energy effi­ciency, thus enabling a stable and at the same time green power sup­ply. How­ever, only a few stor­age sys­tems have been installed so far, espe­cially in medi­um-sized indus­tri­al enter­prises, the cent­ral pil­lar of the Ger­man eco­nomy. Yet a cost-effect­ive power sup­ply and effi­cient use of resources are essen­tial for these com­pan­ies in order to sus­tain­ably sur­vive in inter­na­tion­al com­pet­i­tion. One chal­lenge in identi­fy­ing and real­ising optim­isa­tion poten­tial in this seg­ment, how­ever, is com­plex and very indi­vidu­al pro­duc­tion pro­cesses, a wide vari­ety of entre­pren­eur­i­al frame­work con­di­tions and numer­ous reg­u­lat­ory require­ments, which often require extens­ive analysis.

Prac­tic­al invest­ig­a­tion of meas­ure­ment data and stor­age models

In five suc­cess­ive pro­ject phases, meth­ods of meas­ure­ment data ana­lys­is, mod­els for stor­age dimen­sion­ing, self-learn­ing con­trol algorithms (keyword AI) for stor­age oper­a­tion and scal­able stor­age sys­tem archi­tec­tures are invest­ig­ated or developed and then installed and tested in selec­ted indus­tri­al plants.

Based on a com­bined oper­a­tion of the elec­tric­al stor­age sys­tem for peak load cap­ping and the pro­vi­sion of primary con­trol power, the pro­ject devel­op­ments are inten­ded to optim­ise the siz­ing and oper­a­tion­al man­age­ment of the stor­age sys­tem and integ­rate fur­ther use cases — such as unin­ter­rupt­ible power sup­ply, self-con­sump­tion increase, price-dynam­ic load shift­ing or sta­bil­isa­tion of the loc­al grid.

In par­al­lel, the pro­to­type of a flex­ibly deploy­able, mod­u­lar hybrid energy stor­age sys­tem is being developed, which will com­bine the respect­ive advant­ages of lith­i­um and redox flow stor­age tech­no­logy. Finally, both the pro­to­type and the con­trol algorithms will be extens­ively tested in the Digit­al Grid Lab at Fraunhofer ISE and in a field test.

Fur­ther inform­a­tion is avail­able on the DABESI web­site at https://​dabesi​.de/.

Fun­ded by the Fed­er­al Min­istry for Eco­nom­ic Affairs and Energy on the basis of a res­ol­u­tion of the Ger­man Bundestag
