10 Smart Cities Research and Implementation topics Energy Planning Performance characteristics of city areas Morphology, end use mixes, building energy performance characteristics etc. Methods and tools for simulations (scientific level, city management level) Smart Grids New methods for energy networks planning and operation Smart electric grids (including energy management) Smart thermal grids (heating-, low temperature heating, cooling) Use of potential for shift between thermal and electric load Load management for optimized power station performance E-Mobility grid integration

11 Smart Cities Research and Implementation topics Active Buildings (i.e. housing, industry) Energy efficient, passive houses Energy generation (on site-renewables) Active demand side management, supply & demand profiles optimization (building to grid) Supply technologies On-site renewables (i.e. solarthermal, PV, heat pumps, small wind) Integration in District Heating and Cooling Networks Cascade use of resources Transport Public Transport Modal Split, E Mobility, new fuels

12 Smart District Heating Networks Research project within the Smart Grids Modellregion Salzburg National funding, consortium: AIT, Salzburg AG, (municipal DH supplier) Aim: analysing and evaluating the potential of Smart Grid concepts for district heating systems in the model region of Salzburg Method: Dynamic network simulation and model calculations are applied to investigate intelligent operation strategies and control mechanisms for the reduction of peak loads. 1. Modelling and simulation of the current network state 2. Evaluation of selected smart grid measures in the DH network Power in kw Time in min Temperature [ C] Q normalised [-] Supply temp nostorage Supply temp withstorage 0 Return temp nostorage Return 10 temp withstorage consumption Time [h]

14 Possible smart grid measures in thermal networks II Operational parameters and network controlling Utilising heat pumps for temperature lifting / production of cold joined control of decentralized producers (virtual heating plant) Modification of the pressure- and temperature level (low temperature networks), integration of passive buildings in the return line 80 C e.g. biomass CHP, industrial waste heat 25 C 50 C passive building solar thermal energy e.g. building stoke, warm water preparation Advantages of low temperature DH networks: lowering invest- and operational costs Potential to exploit renewable resources like low temperature waste heat But: warm water preparation difficult! (temp. above 65 C necessary for warm water storage), solutions: additional heating or direct heating w/o storage
