Abstract This research discusses the solar and wind sourcesintegration in aremote location using hybrid power optimization approaches a multi energy storage system with batteries supercapacitors. The controllers PV turbine systems are used to efficiently operate maximum point tracking (MPPT) algorithms, optimizing overall performance while minimizing stress on components. More specifically, generator, provided method integrating Perturb & Observe (P&O) Fuzzy Logic Control (FLC) methods.

Re-thinking energy justice to achieve a fair distribution of shared electricity from rooftop photovoltaics in a typical multi-apartment building in Germany: an interdisciplinary approach

Energy Research & Social Science, Год журнала: 2024, Номер 112, С. 103531 - 103531

An important development in decarbonising energy consumption is the installation of shared rooftop photovoltaics on multiapartment buildings. It widely agreed that distribution this relatively cheap electricity should be "fair" to all users, and simultaneously maximise local use, reduce global CO2 emissions grid load. Most technical studies model or investigate patterns basis, but without critical reflection justice issues arise sharing a common source. This study brings together two distinct disciplines move discussion forward: distributing photovoltaic output; philosophical justice. sets within Bhaskar's philosophy interdisciplinary science which shows why narrow, highly specialist are necessary their findings must brought inform us about actual world we live in. On side, models an apparently fair pattern for system case building Germany. then interrogates outcome terms four different strands philosophy: Rawlsian, Wittgensteinian, pragmatic, "theological" (stemming from environmental movement). finds Rawlsian concepts provide basis just with serious anomalies, while theological avenues these anomalies mitigated. comprehensive cluster approaches therefore very useful alongside expertise, ongoing

Over the past decade, different economic incentives have been created to increase investments in solar photovoltaics (PV). Although research outlines that investors renewable electricity technologies (RET) are heterogeneous, policies not taken this into account when designing subsidy programs. This paper aims analyse relationship between policy and willingness invest PV systems for investor groups, including households, companies, associations, public organizations. Using data from all applications capital program Sweden 2009 2021, we impact of level on over time. Our analysis shows has had a positively significant households private companies as groups. However, also found other variables significantly positive or negative effect stresses need going "one size fits all" better adapted characteristics. To meet urgent accelerate diffusion RETs, our results show heterogeneity responsiveness provide avenues design targeted policies.

Fifth-generation district heating and cooling (5GDHC) systems have the potential to provide simultaneous cooling, allowing for energy exchange between users with different needs. However, their viability in mild climates a higher share of demand remains unclear. In this paper, we propose framework assessing engineering, economic environmental performance 5GDHC system compared state-of-the-art business-as-usual solution demonstrate it through practical case study university campus Melbourne, Australia.

ABSTRACT The pursuit of sustainable development in China necessitates a comprehensive evaluation renewable energy access and environmental justice. As experiences rapid economic growth shifts towards cleaner sources, it is crucial to examine the fairness distribution equitable allocation benefits burdens. This study explores complexities involved balancing energy, social equity, factors. A twofold methodological approach was employed such as fuzzy analytic hierarchy process (AHP) first used systematically assess equity distribution, identifying six key factors 24 sub‐factors that influence results from AHP show burdens socio‐economic are most critical shaping To further refine strategic insights, complex proportional assessment (COPRAS) method applied, ranking approaches for advancing top‐ranked strategy expanding infrastructure underserved regions which emerged impactful, emphasising importance addressing geographic disparities. Following closely were strategies aimed at strengthening financial mechanisms low‐income households promoting community‐led projects, support local empowerment achieving

The results indicate that, SC1, assigns weights 14.35% A1 16.22% A2, while FAHP demonstrates greater dispersion, highlighting A6 with 35.22%. In SC2, prioritizes 14.16%, whereas increases weight criterion 21.18%. SC3, remains preferred option methodologies, close 34.00% for 32.98% FAHP. SC4, methods show similar trends, standing out at 11.12% A4 34.87%. Finally, SC5, allocates 8.52% A1, it 10.73%. findings suggest that allows sensitivity variations sub‐criteria, enabling a more precise evaluation aligned sustainability objectives. significance social criteria underscores necessity incorporating sustainable into decision‐making processes.

Building-integrated photovoltaic systems (BIPVs) is a strategy to achieve energy self-sufficiency in buildings. However, (PV) production presents challenges due its intermittent nature, characterized by variations and uncertainties associated with solar radiation interference from the building’s surroundings. Therefore, building information modeling (BIM) enables simulations performance analyses during design phase of In this context, paper aims identify key strategies for integrating BIM how these approaches support development sustainable projects. A systematic literature review was conducted, combined bibliometric analysis, content coding 63 articles. Results indicate an annual research growth rate 19.62%, contributions 268 authors international co-authorship 22.22%. Core trends BIM-PV context were identified through thematic maps, highlighting four dimensions—BIPV applications, parametric tools simulation, challenges, potential benefits—divided into 32 codes. The findings are synthesized theoretical propositions structured integrative framework. Additionally, five applications integration mapped, along their addressed problems limitations establishing managerial contributions.
