Optimised regional energy balancing in electric power grids using intelligent energy storage concepts

Research funding project
Present situation: The increasing energy demand requires a massive extension of electric power generation capacities. This process leads to energy systems which are more and more de-centrally organised and utilise more renewable energy sources. The demand struc-ture is dynamically changing its pattern and is extremely difficult to forecast. In Austria, espe-cially solar energy, biomass, wind and mini-hydro will play an important role in the future. Assuming positive framing conditions, there will be 20% of domestic power production cov-ered by solar energy according to the recently published ¿Photovoltaik Roadmap ¿ until 2050. The partly fluctuating feed-in and the even more dynamic development with respect to the varying loads are key challenges for the distribution sector. Besides the sophisticated inte-gration of power generators the adequate storage of energy is the key task to be mastered. Storage management is possible in the following ways: ¿ Storage of primary energy carriers (water, biomass) ¿ Storage of secondary energy carriers (electric energy, indirect storage via pumped storage plants, biogas) ¿ Load management as a load balance tool (Demand Side Management and load management such as load shifting or shedding) The primary objective of OREANIS is to compensate the natural generation fluctua-tions of renewable energy technologies by intelligent storage, control and optimisa-tion of the energy demand and generation. Thus, an efficient load balancing mecha-nism in the regional grid can be achieved. Within the project basic issues and the premises for industrial research will be evaluated. Thus the basis for solutions for the challenges of network operation will be created In order to do so the potentials of the three mentioned strategies will be evaluated and a concept for their optimal integration will be elaborated. Subject of Research: OREANIS investigates how; despite of the fluctuating generation caused by renewable generation, a regionally balanced energy and power provision can be managed. The energy balance considers the traditional generation units, the possibilities of energy storage and the options of demand side management.
