Wärmeversorgung in flexiblen Energieversorgungsystemen mit hohen Anteilen an erneuerbaren Energien

Abstract

Today the discussion about the transformation of the energy system is mainly focused on the increasing renewable share of energy generation by wind and solar power. To achieve the ambitious overall climate policy objectives, the sectors heat generation and traffic must be addressed as well. In this paper the focus is set on the integration of electric heat systems (PtH - Power-to-Heat). By those technologies the future power demand will increase, but on the other hand flexibility of the power system is increased to integrate the fluctuating feed-in of wind and solar power. To balance these effects, a mix of highly efficient systems as heat pumps and very flexible hybrid systems should be integrated in the sys-tem. Even today PtH-technologies are a valuable flexibility option to provide ancillary services, to improve adaptability of CHP-plants and integrate fluctuating renewable energy feed-in. Although the technologies are already available, the regulatory framework and the unequal cost burden of electricity and fossil fuels impedes unlocking these potentials. The presented results were generated within the ETG Task Force “Strom im Wärmemarkt”. The detailed study will be released in April 2015
