Intel­li­gent pow­er grids: Ber­gisch Uni­ver­si­ty involved in the devel­op­ment of a trad­ing platform

In the course of the ener­gy tran­si­tion, medi­um and low-volt­age grids are fac­ing new chal­lenges due to the con­stant­ly grow­ing num­ber of decen­tral­ized feed­ers, such as pri­vate pho­to­volta­ic sys­tems on rooftops, and the increas­ing num­ber of pow­er-inten­sive con­sumers, such as e‑mobility. As an alter­na­tive to cost-inten­sive net­work expan­sion, net­work automa­tion solu­tions are grad­u­al­ly becom­ing estab­lished that pro­vide an equiv­a­lent, but in some cas­es con­sid­er­ably less expen­sive, response to the chal­lenges out­lined above. The chair of Prof. Zdrallek has been work­ing in this field for a long time on the research and opti­miza­tion of agent-based con­cepts, which are ide­al for the inter­ac­tion of a high num­ber of dif­fer­ent devices and sys­tems in the sup­ply net­work. The stan­dard­iza­tion of such tech­nolo­gies and sys­tems is of great impor­tance for the progress of the ener­gy transition.

With PEAK, which fol­lows on from the pre­vi­ous project Agent.HyGrid, the Wup­per­tal sci­en­tists and their part­ners are striv­ing to devel­op an inte­grat­ed trad­ing plat­form for ener­gy sup­pli­ers and cus­tomers for the effi­cient con­trol of the elec­tric­i­ty grid and the inte­gra­tion of increas­ing shares of renew­able ener­gies. For a cost-opti­mized solu­tion, they are rely­ing on the use of new elec­tric­i­ty meters, so-called smart meters, and the use of “blockchain” tech­nol­o­gy for reli­able trade set­tle­ment between the con­trac­tu­al part­ners. “The plat­form net­works all par­tic­i­pants in the sup­ply net­work and allows new play­ers to join with­out com­pro­mis­ing sup­ply secu­ri­ty or pre­vent­ing exist­ing net­work capac­i­ties from being opti­mal­ly uti­lized. The focus is on pre­ven­tive grid sta­tus mon­i­tor­ing, which in the best case sce­nario pre­vents grid bot­tle­necks from occur­ring in the first place,” explains Prof. Zdrallek, Chair of Elec­tri­cal Pow­er Sup­ply Technology.

His team con­tributes its expe­ri­ence in the field of net­work mon­i­tor­ing and con­trol. Dur­ing the course of the project, a field test is planned with­in the Smart Grid Lab­o­ra­to­ry at the Freuden­berg Cam­pus of the Ber­gis­che Uni­ver­sität. In addi­tion, fur­ther sce­nar­ios are to be inves­ti­gat­ed with­in the frame­work of a “vir­tu­al pilot”. The focus here is on the growth of decen­tralised feed-in, the expan­sion of e‑mobility and larg­er grid areas.

Research part­ners in the project are the Forschungsstelle für Energiewirtschaft e.V., PSI Ener­gy Mar­kets GmbH, the Uni­ver­si­ty of Duis­burg-Essen, the Ham­burg Uni­ver­si­ty of Applied Sci­ences, Hel­mut Schmidt Uni­ver­si­ty — Uni­ver­si­ty of the Fed­er­al Armed Forces Ham­burg and PSI Grid­Con­nect GmbH.
