In this work, an Hybrid Renewable Energy System (HRES) based on microgrid power is proposed and optimized to meet the electric demand of a sustainable multi-family buildings with possible generation of clean hydrogen. Hourly building simulation is carried out based on meteorological data to predict the year-round electrical consumption of the designed buildings. The proposed hybrid system includes a Solar Dish Stirling (SDS) technology combined with a Wind Turbine (WT) for power generation, an electrolyzer, a hydrogen storage tank, as well as a battery bank. The novelty of the study resides in the replacement of conventional hybrid systems, such as a photovoltaic PV/WT assembly, with an SDS/WT system that has the potential to reach higher efficiencies and economic competitiveness. An optimization process is investigated to evidence the optimum HRES design based on the lowest Net Present Cost (NPC). Sensitivity studies are performed to illustrate the effect of main functioning parameters and how they impact the overall project viability. Moreover, the performance of the model is evaluated in two selected sites in Morocco, namely Ouarzazate and Dakhla, and a comprehensive techno-economic study of the integrated system is investigated. The findings indicate that the HRES design and configuration are site-dependent due to discrepancies in wind and solar energy potential of the examined sites. The optimum architecture of the assessed HRES in Dakhla greatly promote the implementation of WT technology with a NPC/ LCOE of about 3.053 M€/0.0697 €/kWh, respectively. In Ouarzazate, it was found that the optimum design configuration relies exclusively on the SDS technology and correspond to NPC/ LCOE of 3.391 M€/ 0.126 €/kWh, respectively. LCOH values obtained by the optimum HRES configuration were determined 21.4 €/kg and 23.6 €/kg for Dakhla and Ouarzazate, respectively. This study demonstrates the viability of SDS implementation in future HRESs and open the perspectives for its role in carbon–neutral buildings.

在这项工作中，提出并优化了一种基于微电网的混合可再生能源系统（HRES），以满足可持续多户建筑的电力需求，并可能产生清洁氢。根据气象数据进行每小时建筑模拟，以预测设计建筑的全年用电量。拟议的混合系统包括太阳能碟式斯特林 (SDS) 技术与风力涡轮机 (WT) 相结合用于发电、电解槽、储氢罐以及电池组。该研究的新颖之处在于用可能达到更高效率和经济竞争力的 SDS/WT 系统替代传统的混合系统，例如光伏 PV/WT 组件。研究了一个优化过程，以证明基于最低净当前成本 (NPC) 的最佳 HRES 设计。进行敏感性研究以说明主要功能参数的影响以及它们如何影响整个项目的可行性。此外，在摩洛哥的两个选定地点，即瓦尔扎扎特和达赫拉，对模型的性能进行了评估，并对集成系统的综合技术经济研究进行了调查。研究结果表明，由于所检查地点的风能和太阳能潜力存在差异，HRES 的设计和配置取决于地点。达赫拉评估的 HRES 的最佳架构极大地促进了 WT 技术的实施，NPC/LCOE 分别约为 305.3 万欧元/0.0697 欧元/千瓦时。在瓦尔扎扎特，结果发现，最佳设计配置完全依赖于 SDS 技术，分别对应 339.1 万欧元/0.126 欧元/千瓦时的 NPC/LCOE。通过最佳 HRES 配置获得的 LCOH 值分别确定为 Dakhla 和 Ouarzazate 的 21.4 欧元/千克和 23.6 欧元/千克。本研究证明了 SDS 在未来 HRES 中实施的可行性，并为其在碳中和建筑中的作用开辟了前景。
