This paper focuses on the techno-economic feasibility and sustainability of a PV/wind/diesel hybrid system designed for decentralized power supply. Several designs have been studied for the hybrid system by varying the PV slope and wind turbine hub height under different dispatch strategies to supply the load. For each design, the power system has been optimized to determine the maximum electrical output at a low cost. Sensitivity analyses have been performed to evaluate operational risk in the actual operation as well as the cost-effectiveness of the proposed system. As a final remark, the sustainability of the proposed hybrid energy system has been analyzed based on some key indicators to understand the implications of a design choice on electrical production, CO₂ emission and cost of energy. Our results show that for a projected period of 25 years, the selected hybrid power system for electrification of a housing estate will cost 10.2 million USD for a daily load of 4876.5 kWh, and the cost for every kWh of electricity generated is $0.4574. Results also show that the hybridization of the standard diesel generating system increased the reliability and cost-effectiveness of the power system, saving $0.316 for every kWh of electricity generated, with about 1,521,310 kg of CO₂ emission avoided annually.

本文关注于专为分散式电源设计的PV /风/柴油混合系统的技术经济可行性和可持续性。通过在不同的调度策略下改变PV斜率和风力涡轮机轮毂高度来为负载提供负载，已经研究了混合动力系统的几种设计。对于每种设计，电源系统都经过优化，可以低成本确定最大的电输出。已经进行了敏感性分析，以评估实际操作中的操作风险以及所提出系统的成本效益。最后，基于一些关键指标对拟议的混合能源系统的可持续性进行了分析，以了解设计选择对电力生产CO _{2的影响。}排放和能源成本。我们的结果表明，在25年的预计周期内，为住宅小区电气化选择的混合动力系统每天的负荷为4876.5 kWh，将花费1,020万美元，每千瓦时的发电成本为0.4574美元。结果还显示，标准柴油发电系统的混合动力提高了电力系统的可靠性和成本效益，每发电1千瓦时可节省0.316美元，每年可避免约1,521,310千克CO ₂排放。
