The Clean Energy package recognizes and offers a favorable regulatory framework for citizens energy communities with renewable sources. However, various countries’ national regulations will be highly important the successful development of in existing cities surrounding areas. represent way which local authorities can invest clean sources efficiency, several benefits addition to financial ones, like strengthening concept community individual contributions reductions overall carbon footprint. In this paper, an overview recent developments incentives communities, their organization, typologies, as well shared among participants, is performed. reveals potential contributing economic, energetic, social towards sustainable smart cities.

Ignore variability, overestimate hydrogen production – Quantifying the effects of electrolyzer efficiency curves on hydrogen production from renewable energy sources

International Journal of Hydrogen Energy, Год журнала: 2024, Номер 72, С. 49 - 59

Опубликована: Май 27, 2024

This study investigates the impact of including (or neglecting) variable efficiency hydrogen electrolyzers as a function operating power in modelling green produced from renewable energy sources. Results show that neglecting electrolyzer efficiency, is commonly done studies hydrogen, leads to significant overestimation production range 5–24%. The effects time resolution used models are also investigated, well option for switch stand-by mode instead powering down and ramp rate constraints. indicate these have minor effect on overall production, with use hour data leading 0.2–2%, relative using 5-min data. three solar farms wind Australia, which it observed 55% more than farms. results this highlight critical importance production. As industry scales, continuing neglect would lead by tens megatonnes.

Sustainable Water Resources Management and Energy Production in Small Mediterranean Islands

Environmental Processes, Год журнала: 2025, Номер 12(2)

Опубликована: Апрель 2, 2025

Abstract The study aims to address the challenges of water scarcity and energy instability faced by small Mediterranean islands, exacerbated tourism population fluctuations. A Hybrid Renewable Energy System (HRES) is proposed provide sustainable solutions integrating wind turbines, pumped hydro storage, hydrogen desalination. methodology involves simulating system’s operation in two islands using historical data, calculations, storage dimensioning. Three scenarios are evaluated: a combination both, with focus on covering demand, while minimizing costs. Results indicate that combined scenario achieves 87% electrical demand satisfaction, surpassing single scenarios. Desalination ensures 99.99% coverage across all scenarios, marginal costs for potable calculated at 3 €/m³ 0.016–0.131 €/kWh, respectively. method proves more efficient, adds flexibility system. findings highlight adaptability HRES globally, offering replicable model addressing water-energy nexus. provides practical insights into renewable energy, innovative solutions, desalination development isolated regions.

Optimizing Power Flow in Photovoltaic‐Hybrid Energy Storage Systems: A PSO and DPSO Approach for PI Controller Tuning

International Transactions on Electrical Energy Systems, Год журнала: 2025, Номер 2025(1)

Опубликована: Янв. 1, 2025

This paper focuses on developing power management strategies for hybrid energy storage systems (HESSs) combining batteries and supercapacitors (SCs) with photovoltaic (PV) systems. The proposed control scheme is based proportional‐integral (PI) controllers optimized particle swarm optimization (PSO) duplicate (DPSO) algorithms. aim to reduce peak current the system’s response time while enhancing stability during charging discharging of HSS under various operating conditions. A comparative study other tuning methods presented demonstrate effectiveness DPSO algorithm in duplication, population diversity, convergence speed toward global optimum, overall performance. results feasibility robustness PI − providing quick accurate responses even variable load, solar irradiations, temperature, thus dynamic SC reducing battery stress, resulting a longer lifespan HESS.
