description: The OrPHEuS project elaborates hybrid energy network control strategies for smart cities implementing novel
cooperative approach for the optimal interactions between multiple energy grids. The OrPHEuS project aims at
optimising the synergies between multiple energy grids by enabling simultaneous optimization for individual
response requirements, energy efficiencies and energy savings as well as coupled operational, economic and
social impacts.
The project will investigate the implementation of the control strategies on specific use cases scenario in two
demonstration sites located in the City of Skellefteå in Sweden and in the City of Ulm in Germany. The
operational focus of the project is the cross-domain coupling of energy infrastructures in order to increase
energy efficiency through energy transformation and grid coupling. In particular, the project researches
scenarios for transition between energy resources and flexible infrastructures e.g. along Power-to-Heat
processes. It investigates the balancing of fluctuating renewable energy generation against the flexibility in
supply, demand and storage capacities within the power grid and via process coupling across energy networks.
The project will look on technical as well as socio-economical aspects considered as multi-dimensional
strategy framework.
With respect to the hybrid energy characteristics, both demonstration sites are quite distinct. At the
demonstration site in Sweden, the reduction of vertical production (driven unsustainable with fossil fuel) is in
the centre of the targeted control strategies. Looking on the specifics of the Ulm testing site, the major issue is
the balancing of the high penetration of solar generation under today’s operation with a pre-dominant
operational challenge for PV control. The key focus is to define control strategies to increase the intake of the
energy supply from PV on the roof generation into the grid while maximizing the benefits for the low voltage
power grid.
The 29th European Photovoltaic Solar Energy Conference and Exhibition (EU PVSEC) in Amsterdam
represented a unique opportunity to present information on the methodology adopted by the OrPHEuS
Consortium to optimise the synergies between multiple energy grids. On the occasion of the EU PVSEC the
OrPHEuS Consortium focused the project presentation on how to optimise the PV electricity production with
the implementation of Information and Communication (ICT) devices at the Ulm demonstration site, the Test
area in Einsingen, which presents an over production of the PV electricity of 230 MWh annually. The average
annual electrical consumption is around 1000 MWh.
