This paper presents a novel approach to modeling the gradual reduction in heat demand and evolving expansion of district heating (DH) grids for assessing DH potential EU member states (MS). It introduces new methodological elements impact connection rates below 100% on distribution costs both dense sparse areas. The projected 2050 is derived from decarbonization scenario published by EU, which would lead 3128 TWh 2020 1709 2050. proposed yields information economic areas, potential, average...
District heating can play a decisive role in the transformation to climate-neutral building sector, replacing fossil fuels. Renewable and excess heat potentials for district are often spatially limited consistent EU-wide analysis of is not yet available. In this paper, we quantify renewable that could supply future areas entire EU. We combine different data sets with high spatial resolution conduct matching. Subsequently, cluster results individual derive representative types. The show...
The planning of heating and cooling supply demand is key to reaching climate sustainability targets. At the same time, data for are scarce many places in Europe. In this study, we developed an open source dataset gross floor area energy space hot water residential tertiary buildings at hectare level EU28 + Norway, Iceland, Switzerland. This methodology based on a top-down approach, starting from consistent country (NUTS 0), breaking down NUTS 3 further by means series regional indicators. We...
This paper presents an overview of policy frameworks for district heating (DH) in Europe. We develop a classification aspects addressing DH, comprising regulation ownership, prices, metering, consumer grid connection, third party access as well support schemes and carbon taxes. builds on existing literature expert assessments collected online survey interviews. The relevance the lies giving comprehensive picture DH 23 European countries. For overview, countries are clustered along assigned...
In this paper, we use a heat density map (HDM) and plot ratio to propose GIS-based method for determining potential DH areas with specific focus on district heating (DH) grid costs. The are determined via performing sensitivity analyses the HDM under consideration of predefined upper bound average distribution approach additionally allows estimation length diameter transmission lines their associated outputs GIS layers that illustrate economically viable construction as well cost-minimal...
The optimal placement of Distributed Generation (DG) has attracted many researchers' attention recently due to its ability obviate defects caused by improper installation DG units, such as rise in system losses, decline power quality, voltage increase at the end feeders and etc. This paper presents a new advanced method for allocation distribution systems. In this study, optimum location units is specified introducing losses profile variables into objective function. Particle Swarm...
Since the introduction of effective width concept for estimation linear heat density, it has been frequently used by researchers to calculate district heating distribution grid costs in pre-feasibility phases. Some however, still prefer using a detailed modelling approach get reliable results. This paper aims at highlighting advantages, disadvantages and challenges calculation comparison detailed, optimisation-based such as DHMIN. The outcomes this reveal that although there are differences...
This paper focuses on the requirement of Energy Efficiency Directive for assessing potential efficient heating and cooling. The describes method calculating economic district (DH) in Austria under different scenarios, assuming full decarbonisation sector by 2050. A spatially explicit approach is used to derive heat demand density maps, distribution costs DH areas. obtained areas are clustered, depending their spreads, up four supply portfolios installed generation capacities assessed each...
Reducing the heat demand in buildings is a key pillar for reaching 100% renewable energy systems. To identify meaningful future heating systems, it important to understand effects of different renovation scenarios on costs savings and location demands. In this work we present method develop potential useful density maps by identifying least-cost combinations pre-defined city-wide saving targets. First, set up consistent databases cities merging data from city administrations Invert database....
