Short discription of the subject

Wind power and photovoltaics represent an essential part of the future energy supply which is based on regenerative energy sources. The fluctuating energy derived from sun and wind does not ensure a reliable and perfect source of energy. Hence, the remaining share of energy, a so-called „residual“ share must be covered by further sources of energy.

On the one side, the potential of pumped storage hydro power stations is limited. On the other side electrical energy storage technologies cannot be applied as soon as needed because of technical as well as economical reasons. Therefore, the use of flexible power plants based on fossil fuels is still very important. The more of its waste heat is used for heating matters the more efficient the power plants can be operated. Moreover, the storage of the thermal energy can bridge a lowered demand in thermal energy meanwhile the required electricity can be provided.

In this dissertation the energy supply- and demand-structures are analysed within buildings and in urban districts. Storage management rules are established and implemented in various energy supply scenarios fulfilling the future requirements in energy economics. Based on an existing residential area certain storage concepts are developed and its potential is derived to meet the needs for an efficient energy management.
