The Renewable Energy Sources (RES) have marked a new trend in the Indian energy market and sustainable energy development. In countries like India, the consumers are more welcomed to be prosumers by utilizing the primary renewable energy sources such as solar, wind, biogas, geothermal etc. The renewable energy generation is highly dynamic and thus, Hybrid Energy Systems (HES) strengthens its scope in self-dependent energy generation of the consumers. This paper proposes techno-economic analysis of a Hybrid Energy System (HES) design that has been set up at Kamaraj College of Engineering and Technology (KCET), Virudhunagar, Madurai, Tamil Nadu, India. The paper investigates the on-grid and off-grid operation of the proposed HES. The system is designed and optimized by using HOMER (Hybrid Optimization Model for Electric Renewables) software. The feasibility of the HES system is studied under different dispatch strategies such as Cycle Charging (CC) and Load Following (LF) for both on-grid and off-grid operation. Further, the sensitivity analysis is carried out for the proposed HES system with the fuel price and scaled annual solar radiation as sensitivity variables. The Net Present Cost (NPC) and Cost of Energy (COE) of the system under different architectures are determined and it is found that, the on-grid HES with LF dispatch is the optimal system design for the selected location. The performance of the system is studied in both technical and economic perspectives to optimally design the HES components and a minimum NPC of $ 7.66 M has been obtained.

可再生能源（RES）标志着印度能源市场和可持续能源发展的新趋势。在印度等国家，利用太阳能，风能，沼气，地热能等主要可再生能源，使消费者更容易成为生产者。可再生能源的产生是高度动态的，因此，混合能源系统（HES）扩大了其范围在消费者自力更生的能源中。本文提出了一种混合能源系统（HES）设计的技术经济分析，该设计已在印度泰米尔纳德邦马杜赖的维鲁德纳加尔的卡马拉吉工程技术学院（KCET）建立。本文研究了拟议的HES的并网和离网操作。该系统是通过使用HOMER（电力可再生能源的混合优化模型）软件进行设计和优化的。在不同的调度策略下（例如循环充电（CC）和负荷跟踪（LF）），对HES系统的可行性进行了研究，以用于并网和离网运行。此外，针对拟议的HES系统，以燃油价格和按比例换算的年度太阳辐射作为灵敏度变量，进行了灵敏度分析。确定了不同架构下系统的净现值（NPC）和能源成本（COE），发现采用LF调度的并网HES是所选位置的最佳系统设计。从技术和经济角度对系统的性能进行了研究，以优化设计HES组件，并获得了最低NPC 766万美元。
