Abstract

The integration of conventional and renewable energy sources offers a viable solution for electrifying remote and underserved regions of India, where reliable grid connectivity remains a challenge. This paper presents a comprehensive techno-economic analysis of a Solar Photovoltaic (SPV)-based System for Integrated Electricity Generation (SIEG) tailored for a remote area in West Bengal, Eastern India. The system’s performance is rigorously evaluated using a suite of performance indices, alongside a detailed feasibility study that incorporates both economic and environmental metrics. The SPV system exhibits a performance ratio of 77.50 % and an average annual capacity factor of 16.78 %, attributable to the local climatic conditions. The system design and optimization are carried out using the Hybrid Optimization Model for Electric Renewables (HOMER) software, which facilitates the integration of solar energy with conventional generation resources and storage solutions. The optimal configuration, designed to meet a 30.39 kWh/d load, consists of a 12.4 kW SPV array, a 6 kW diesel generator set (DGS), a 19 kWh battery storage unit, and a 4.83 kW converter. This hybrid setup delivers the lowest cost of electricity (COE) at $0.248/kWh, with a total present cost (TPC) of $35,627.85. The system achieves a high renewable fraction (RF) of 96.66 %, substantially reducing carbon emissions by 97.5 % compared to a standalone DGS configuration. Furthermore, the hybrid system’s TPC and COE are 76.4 % lower than those of a conventional DGS-only setup. To evaluate the robustness and adaptability of the proposed system, a multi-dimensional sensitivity analysis is performed. This analysis examines the impact of variations in critical parameters, including energy resource availability, fuel costs, and load profiles, on the COE and system performance. The findings underscore the feasibility and economic viability of the hybrid SIEG system as a sustainable and resilient energy solution for rural electrification in Eastern India.

评估spv驱动的自动发电系统在印度偏远地区电气化的可行性和技术经济可行性

传统能源和可再生能源的整合为印度偏远和服务不足的地区提供了一个可行的解决方案，在这些地区，可靠的电网连接仍然是一个挑战。本文介绍了为印度东部西孟加拉邦偏远地区量身定制的基于太阳能光伏（SPV）的综合发电系统（SIEG）的综合技术经济分析。该系统的性能使用一套性能指标进行严格评估，同时进行了详细的可行性研究，包括经济和环境指标。由于当地的气候条件，SPV系统的性能比为77.50%，年平均容量系数为16.78%。利用可再生电力混合优化模型（HOMER）软件进行系统设计和优化，促进太阳能与传统发电资源和存储解决方案的整合。最佳配置由12.4 kW的SPV阵列、6 kW的柴油发电机组（DGS）、19 kWh的电池存储单元和4.83 kW的变流器组成，可满足30.39 kWh/d的负载。这种混合动力装置提供最低的电力成本（COE），为0.248美元/千瓦时，总当前成本（TPC）为35,627.85美元。该系统实现了96.66%的高可再生部分（RF），与独立的DGS配置相比，大大减少了97.5%的碳排放。此外，混合系统的TPC和COE比传统的仅dgs设置低76.4%。为了评估系统的鲁棒性和适应性，进行了多维灵敏度分析。该分析检查了关键参数（包括能源资源可用性、燃料成本和负载概况）变化对COE和系统性能的影响。研究结果强调了混合SIEG系统作为印度东部农村电气化的可持续和弹性能源解决方案的可行性和经济可行性。
