Control- and Optimization-System for Energy-Efficient Operation of District-Heating Networks with Biomass-Plants

Forschungsförderungsprojekt
The operation of small and medium-sized decentralised biomass power plants (heating plant and cogeneration) is characterised by a low degree of automation, high losses in the furnace and an inefficient operation of the district heating networks. This is mainly due to tenders that do not sufficiently consider plant efficiency, allowable fuel quality bandwith and efficiencies of subprocesses. Small and medium-sized energy-supply plants are mostly equipped with very limited control concepts, which are usually delivered by the plant suppliers themselves. This reduces initial investment costs and comissioning costs, however at the expense of increased operational costs. Plant operators are often lacking the know-how for an integrated economic and eco-logical controller optimization for the powerplant and the distribution network. BioNetControl-System constitutes a set of fully integrable tools for the optimization of the energy efficiency, the controller performance as well as the intelligent behavior of decentra-lised district heating networks in combination with biomass power plants. From the process data collected from two pilot plants of an Austrian energy provider a universally applicable toolkit for dynamic modeling , control and optimization of biomass power plants in connec-tion with district heating networks will be developed. An important goal is a broad applicability of the developed tools. This will be achieved through a modular design and a highly struc-tured configuration of the dynamic models and the associated control concepts. In this way one can both backfit existing plants or support the design of new plants as early as in their planning phase. The general validity of the system will be proved through testing and validation at two pilot plants with different scales, in different regions and with differing energy consumption schemes. The practical relevance of the project findings is ensured by an interdisciplinary composition of the project consortium. It includes know-how in the fields of process engineering, system integration and theoretical system analysis as well as advanced process control. The system integration of control- and optimization algorithms into the automation concepts of the plant will lead to a significant enhancement of the efficiency of district heating networks in conjunction with biomass power plants subject to varying load profiles. The know-how transfer from TU-Vienna to an innovative Austrian small company with excel-lent international customer relations to numerous operators of biomass power plants as well as to the biggest industrial energy consumers from the paper and wood processing industries ensures many chances for implementation. This in turn entails massive effects on the effi-ciency of systems for energy production and distribution.
