NE-IF: Super-4-Micro-Grid - Sustainable power supply regarding climatic change The future shortage of fossil resources, caused by increasing demand of industrialized countries and industrialization of developing countries will affect the security of supply and accelerate the climate change. In future the renewable energy supply tends into two directions with centralized and decentralized technologies. Centralized technologies are represented by hydraulic power stations of the type of run-of-river, pumped storage and large wind parks, which are directly connected to the transmission systems. Decentralized technologies form micro grids with the integration of photo voltaic, solar thermal, geo thermal, small-scale hydro, wind power and biomass cogeneration. By the climate change it can be presumed, that extreme weather conditions can influence unfavourable the predominant renewable energy supply. By supra regional interconnection of decentralized and centralized technologies a balance between regions can be established. Centralized pumped storage plants can provide balancing energy and respectively store surplus energy. The expected influences on climate change are gained from analyses of records of historical weather data and extreme weather conditions. Effects on hydraulic energy conversion are derived from run-off probabilities for variable averaging-cycles. For wind and solar energy, historic time series are taken. Out of historic weather analysis and extrapolation of climate change, it is also possible to gain information about coupled risks on restrictions of energy generation by different types of regenerative sources. So, strategies for mixed energy generation with diminishing risks can be gained. Expected results: Which regenerative generation mix is necessary for a low in risk supply? Which seasonal coverage with regenerative energy is possible at which increase of energy efficiency? What are the possibilities to minimise the risks by using various generation mixes and energy storages? How can the risks be minimised by a supra-regional interconnection of wind power? Is it possible to realise a fully regenerative power system by the use of pumped storage plants? Which effects can be achieved, when using vehicle batteries for storing surplus energy as well as using them as energetic recovery systems?
