“…While exploring the techno-economic implications of the expansion of district heating in the urban environment, Dominkovic D., concluded that thermal energy storage integration as well as the interconnection of adjacent district systems, can rapidly increase their socioeconomic feasibility [49]. One of the most important works in the field, that of Sebastyen T. et al, made the literature connection between prosumers (in a small village/LEC) and district heating systems.…”

Thermal/Cooling Energy on Local Energy Communities: A Critical Review

2022

View full text Add to dashboard Cite

One of the most crucial factors for energy transition and the incorporation of renewable energy sources into the existing energy map is citizen engagement. Local energy communities (LECs), which are cooperative-based coalitions aimed at reducing the carbon footprint of the residential building sector, have received increasing attention in the past decade. This is because residential buildings account for almost half of the total energy consumed worldwide. A resounding 75% of it is used for thermal energy consumption, heating and cooling, cooking and bathing. However, the main focus of the literature worldwide is explicitly on electrical LECs, despite the fact that the significant increase in natural gas and oil prices, creates instability in the heating and cooling prices. The scope of this study is to provide an overview of the research field regarding Thermal LECs, using both a thorough literature review as well as bibliometric analysis (VOSviewer software), in order to validate the findings of the review. The results indicate a collective scarcity of literature in the field of thermal/cooling energy communities, despite their proven value to the energy transition. A significant lack of directives, research background and state initiatives in the context of LECs incorporating thermal/cooling energy production, storage and distribution systems, was also observed. Case studies and the applications of such systems are scarce in the available literature, while published studies need further feasibility assessments.

“…The total daily space heating (SH) demand for each geographical zone was calculated based on the proportion of day-specific heating, in degree days [20]. Some studies also have been conducted to evaluate heat losses in DH systems by efficient transmission loads along a distribution network [21,22] as well as determining the location of thermal energy demands [23,24]. Discovering the location of huge thermal demands (large building size and high demand) in terms of DH network energy efficiency is crucial.…”

Heat Mapping, a Method for Enhancing the Sustainability of the Smart District Heat Networks

District heating (DH) has a major potential to increase the efficiency, security, and sustainability of energy management at the community scale. However, there is a huge challenge for decision makers due to the lack of knowledge about thermal energy demand during a year. Thermal energy demand is strongly dependent on the outdoor temperature, building area, and activities. In this context, this paper presents an innovative monthly thermal energy mapping method to calculate and visualize heat demand accurately for various types of buildings. The method includes three consecutive phases: (i) calculating energy loss, (ii) completing a dataset that includes energy and building information, and (iii) generating the monthly heat demand maps for the community. Determining the amount of demand and the best location for energy generators from the perspective of energy efficiency in a DH system in an urban context is one of the important applications of heat maps. Exploring heat demand characteristics and visualizing them on maps is the foundation of smart DHs.

“…A unified steady-state energy flow analysis considering electrical, natural gas and heating networks with gas-driven CHP facilities as the coupling points was presented in [24]. Excluding the electrical sector, heating and cooling sector alone accounts for a large portion of the energy consumption portfolio (with 50% of European Union's annual energy consumption in 2019) [25]. Further, in the European Union, the largest energy source for heating and cooling is natural gas with 46% share [25].…”

The increasing urban population imposes a substantial and growing burden on the supporting infrastructure, such as electricity, water, heating, natural gas, road transportation, etc. This paper presents a Hetero-functional graph theory (HFGT) based modeling framework for these integrated infrastructures followed by an analysis of network robustness. The supporting infrastructures along with the infrastructure repair facilities are considered. In contrast to conventional graph representations, a weighted HFGT model is used to capture the system processes and mutual dependencies among resources. To assess robustness of the inter-dependent networks, impacts of complete/partial and random/targeted attacks are quantified. Specifically, various contingency scenarios are simulated and the vulnerability of the network is evaluated. Additionally, several robustness metrics are proposed to provide a comprehensive evaluation of system robustness. The proposed weighted HFGT modeling and robustness assessment approach is tested using a synthetic interdependent network, comprising of an electrical power system, a water network, a district heating network, a natural gas system and a road transportation network. Results demonstrate that system robustness can be enhanced via securing system information and mitigating attack strength.
