Nueburg an der Donau, Germany
The main objective of the planned project is to identify and demonstrate the
possibilities of optimizing the operation of district heating grids as part of a
hybrid energy system in the course of the necessary transformation of the
district heating supply. The focus of the investigations is on the development of
a generation-oriented or grid-oriented operation of two existing physically
separated energy systems in the sectors “electricity” (electrical energy systems)
and “heat” (thermal energy systems). To achieve this goal, approaches for
optimized and integrated operation by combining electrical distribution grids
and district heating grids are being developed, tested, evaluated, and
implemented, considering technical, economic, and regulatory framework
conditions. First, the simulation-supported development of operating strategies
for hybrid grid structures will be carried out, taking into account the grid-serving
coupling of the “electricity” and “heat” sectors. The aim is to show how
a comprehensive flexibilization of existing district heating systems must be
designed in the context of hybrid network structures to meet future demands
on the district heating system as a result of its transformation. The developed
operating strategies will be tested on a test site for power and heat grids to
identify synergy potentials for increasing the efficiency and flexibility of hybrid
grids. Finally, the developed operating strategy will be implemented in a sample
neighborhood of the city of Neuburg a. d. Donau, Germany.
