Hybrid Renewable Energy Systems (HRESs) are noteworthy devices for enhancement of reliability and performance compared to standalone systems, which are in a combination of more than one energy conversion system in a single unit. The recent developments in materials and technologies of HRESs are cost-effective and are more suitable power options for isolated rural areas. Many researchers have reported to have enhanced the performance of HRESs across India. Hence, this paper presents a comprehensive review of various HRESs that have been reported for their performance evaluation with respect to economic distance limit, techno-economic sensitivity, and optimum analysis. Also, different hybrid combinations are compared based on the factor of Net Present Cost (NPC), Cost of Energy (COE), renewable fraction, maximum renewable penetration, operational cost, and/or emission. Some case studies on various combinations of HRES for telecommunication application, rural electrification and water distillation are discussed and compared. It is concluded from the comprehensive review that there is scope for further studies on hybrid system across the country with adoption of different and newer combinations, materials and thermodynamic approaches. This paper will be helpful to researchers and scientists in understanding the state-of-the-art technologies in the hybrid system.

Nigeria has great renewable energy resource potential comprising solar, wind, biomass and hydro and much work has been done on estimation of this potential. Variability of a single resource type, high cost of energy from renewable sources and impracticability of grid extension to distant rural areas from the national grid has led to the development of hybrid renewable energy systems (HRES). Although Nigeria is rich in these renewable resources, a hybrid application approach seems more feasible to ensure a reliable and cost-effective power supply from these sources. This study was conducted to assess Nigeria’s technological readiness for adopting HRES, its environmental impact and its viability over a 20-year period. A review of past literature was carried out to ascertain the country’s readiness for HRES and its environmental impact, while the discounted cash flow (DCF) analysis, along with other economic indicators of net present value (NPV), internal rate of return (IRR) and payout period (PO) were adopted to estimate the economic viability of the system. The outcome of this paper shows that HRES for power generation in Nigeria is economically viable.

In this study, a techno-economic feasibility analysis of hybrid renewable energy systems for four household categories in rural areas of Chad was studied based on the multi-criteria assessment technique. The problem of this study is to know the best optimal solution in the technical and economic feasibility study of the decentralized mini-grids for the rural electrification of isolated villages in Chad. The main objective of the work is to assess technically, economically and environmentally the feasibility of six scenarios of hybrid systems in five isolated sites in Chad. The performance analysis involved six scenarios of possible hybrid solutions while achieving a supply-demand balance for sustainable electrification of the remote villages, using the HOMER software. The results have shown that the optimum combination of the hybrid system was the photovoltaic/battery system with a Net Present Cost (NPC) of US $ 328,146 and it was found at Etena village. The photovoltaic/Wind/Diesel/Battery hybrid configuration was the least optimum system and it has appeared in Mandelia village. In terms of energy cost, the lowest Levelized Cost of Energy (LCOE) was estimated at US $ 0.236/kWh in a photovoltaic/Wind/Battery configuration at Koundoul site and the highest costs US $ 0.363/kWh in the photovoltaic/Battery configuration at the Linia site. It is established that hybrid solutions can be developed to make electricity available and accessible to the population of the remote rural areas in Chad. However, it is imperative that the local government must subsidize the diesel price to promote the adaptation of the abundant renewable solutions.
