This paper introduces a Multi-Objective Energy Management System (MOEMS) designed for micro-grids and energy communities, emphasizing resilience and sustainability. Unlike conventional Energy Management Systems (EMS), which mainly focus on cost and efficiency, MOEMS takes a user-centered approach. It incorporates a democratic decision-making process that involves all stakeholders, enabling personalized energy management tailored to user preferences and environmental considerations. MOEMS is used to address grid challenges like power congestion and voltage issues while balancing diverse stakeholder goals. The optimization problem is formulated as a mixed-integer non-linear program and adopted to be solved using a free and open-source solver. The proposed framework leverages the results of a multi-objective optimization model, allowing users to define their preferences. By specifying an acceptable solution space, the central controller in the micro-grid can optimize operations while ensuring that the selected solutions align with user expectations. The system is validated through simulations and a real-world micro-grid case study, demonstrating its adaptability to different setups. To evaluate its effectiveness, MOEMS is compared with traditional EMS approaches, including profile steering and methods that prioritize economic and environmental factors. A real-time implementation in the Kezo micro-grid further demonstrates its capability to dynamically manage energy flows, meet user energy demands, and adapt to real-time fluctuations in supply and demand. Significantly, MOEMS achieved up to 22% higher annual electricity cost savings and a 37% reduction in CO2 emissions compared to traditional EMS methods.</div></div>","PeriodicalId":11798,"journal":{"name":"Energy Reports","volume":"14 ","pages":"Pages 185-204"},"PeriodicalIF":4.7,"publicationDate":"2025-06-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144280229","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Most research in energy communities delves into strategies for enhancing sustainability, economic viability, and fairness. However, these strategies’ effectiveness largely depends on each energy community’s specific characteristics, including members types and available assets. This study focuses on understanding the impact of input parameters across different energy community typologies. It examines community size, the percentage of prosumers, and the diversity of members’ power profiles, analyzing 24,000 distinct configurations derived from an initial dataset of 92 load profiles. The study evaluates multiple setups for individual choices of solar photovoltaic systems and energy storage assets. The assessment applies a collective optimal management strategy to compare self-consumption and potential energy bill savings against a baseline where end-users operate individually. The same management strategy is applied consistently across various energy community typologies to demonstrate that the outcomes are primarily determined by the diversity of inputs (i.e., the energy community’s specific characteristics) rather than the energy management approach itself. The results indicate that energy communities with more than 20 members do not experience significant performance enhancements, regardless of operational choices. Additionally, the findings highlight that diversifying member types is more beneficial than oversizing the generation and storage asset capacity. Ultimately, the results exhibit that energy communities with a percentage of only consumers yield favorable outcomes for all members. Optimal configurations are identified when the composition comprises 75% of prosumers with heterogeneous load profiles.</div></div>","PeriodicalId":11798,"journal":{"name":"Energy Reports","volume":"14 ","pages":"Pages 173-184"},"PeriodicalIF":4.7,"publicationDate":"2025-06-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144272626","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Careful renovation, maintenance and management practices are needed to ensure that heritage values in historic buildings are not lost. However, there is little empirical evidence of the life cycle processes from renovation practices and the greenhouse gas emissions (GHGe) associated with them. This study presents a life cycle-based assessment of 56 historical buildings in Denmark. Results show GHGe in the range of 3–178 kg CO<sub>2</sub>eq/m<sup>2</sup> and a median of 66 kg CO<sub>2</sub>eq/m<sup>2</sup>. These numbers represent the production, construction waste treatment and final end-of-life modules of the building life cycle. Maintenance logs from the 56 case study buildings over a period from 2015 to 2023 provide unique insights into real maintenance-repair-replacement activities. These numbers show, in general, negligible GHGe to the overall result, although a few of the replacement activities show to be significant. Future logging and improved granularity in modelling between maintenance, repair and replacements could provide valuable insights for research and practice. Post-renovation median energy use for heating and hot water is found at 123 kWh/m<sup>2</sup>/year for residential- and 119 kWh/m<sup>2</sup>/year for non-residential buildings. The heating technology in place shows to be the most important determinant for the life cycle GHGe from the renovated buildings, pointing to the importance of effective energy management and energy use practices.

This study shares findings from a hydrogen survey conducted within the Interreg Alpine Space AMETHyST project, which included questionnaires and roundtable discussions across Alpine territories. The survey explored hydrogen’s role in decarbonizing the Alps, gathering insights from local stakeholders about their knowledge, expertise, needs, and targets for hydrogen solutions. It also mapped existing hydrogen initiatives. Results revealed strong interest in hydrogen implementation, with many territories eager to launch projects. However, high investment and operational costs, along with associated risks, are key barriers. The absence of clear local hydrogen strategies and of a comprehensive regulatory framework also poses significant challenges. Incentivization schemes could facilitate initiatives and foster local hydrogen economies. The most promising application areas for hydrogen in the Alps are private and public mobility sectors. The residential sector, particularly in tourist accommodations, also presents potential.

Specifically, we employ Variational Autoencoders (VAEs) and Generative Adversarial Networks (GANs) trained on real-world PMU datasets to learn the underlying empirical data distributions without assuming predefined statistical models. The proposed deep generative models are evaluated against traditional statistical techniques based on Gaussian Copulas using a suite of distributional similarity metrics, including Kullback–Leibler (KL) divergence, Hellinger distance, Maximum Deviation Nearest Neighbor (MDNN), and the Kolmogorov–Smirnov (KS) test. The GAN model achieved the best distributional fidelity, with KL divergence as low as 0.0106 and Hellinger distance of 0.0435 for voltage signals. In a synthetic data reconstruction task with 0.5% missing values, the GAN reduced the percentage root mean squared error (PRMSE) to 0.52% for voltage and 2.19% for current—significantly outperforming baseline methods. Moreover, the GAN was able to augment the dataset from 1489 to 5000 samples while preserving key statistical properties, as validated by empirical distribution tests.
