Abstract

Diesel generator Photovoltaic Emission reduction Hybrid power system Techno-economic sizing A B S T R A C T Present study investigates the viability of a photovoltaic-diesel-battery hybrid system for electricity generation in Nigeria. It aims to determine the economic, technical and environmental benefits of running a solar photovoltaic (PV) system in Nigeria climatic conditions. The solar irradiation for Abuja (latitude 9.08 °N and longitude 7.53 °E) and residential energy profile are used. The optimum size of the hybrid system is determined by making energy-balance calculations based on Hybrid Optimization Model for Electric Renewable (HOMER) software. The impact of interest rate and cost of PV system on the optimum configuration is investigated. Sensitivity analysis is performed by varying the annual average solar irradiation based on solar radiation map of Nigeria and diesel price to determine the viability for other locations. Results showed that the use of PV-diesel-battery system in Nigeria can bring benefits of cost saving and emission reduction without compromising the reliability. However, the range of economic benefits depends on the site meteorology, which varies from 21 to 61%.

尼日利亚光伏-柴油-电池混合动力系统的可行性

柴油发电机光伏减排混合电力系统技术经济规模本研究调查了尼日利亚光伏-柴油电池混合发电系统的可行性。它旨在确定在尼日利亚气候条件下运行太阳能光伏(PV)系统的经济、技术和环境效益。使用阿布贾(纬度9.08°N和经度7.53°E)的太阳辐照和住宅能源剖面。基于可再生电力混合优化模型(HOMER)软件进行能量平衡计算，确定了混合系统的最优规模。研究了利率和光伏系统成本对最优配置的影响。根据尼日利亚太阳辐射图和柴油价格，通过改变年平均太阳辐照度进行敏感性分析，以确定其他地点的可行性。结果表明，在不影响可靠性的情况下，在尼日利亚使用光伏-柴油电池系统可以带来节约成本和减少排放的好处。然而，经济效益的范围取决于现场气象，从21%到61%不等。
