Ghana is endowed with lot of potentials in the renewable energy sector which are yet to be fully exploited. This research evaluated the techno-economic potentials of PV-Wind-DG-Battery and Wind-DG- Battery hybrid power plants in the southern part of Ghana in a town call Mankwadze to ascertain the bankability of the two systems for large-scale commercial electricity generation. The levelized cost of energy (LCOE) and net present cost (NPC) metrics were used in the economic analysis of the modelled power plants. The LCOE and NPC of the two systems were estimated at 0.382 $/kWh and $8,649,054 for the PV-Wind-DG-Battery system, respectively, whiles the Wind-DG-Battery system also recorded 0.396 $/kWh and $8,966,700 for the LCOE and NPC, respectively. The base case (generator) recorded an LCOE of 0.412 $/kWh and an OC of $345,998 with an initial cost of $454,256. The obtained results are all relatively higher than the current cost of energy for household consumers in Ghana, but a sensitivity analysis showed that the LCOEs can be reduced when certain parameters such as cost of fuel, discount and inflation rates are varied. This suggests that such projects can be done when the necessary investment climate is created by those in authority.

加纳南部独立混合能源系统的可行性研究和经济分析

加纳在可再生能源领域拥有许多潜力,尚待充分开发。这项研究评估了加纳南部一个叫Mankwadze的城镇中的PV-Wind-DG-Battery和Wind-DG-Battery混合电站的技术经济潜力,以确定两种大型商业用电系统的可融资性代。在建模电厂的经济分析中使用了平均能源成本(LCOE)和净现值(NPC)指标。PV-Wind-DG-Battery系统的两个系统的LCOE和NPC分别估计为0.382美元/千瓦时和8,649,054美元,而Wind-DG-Battery系统的LCOE和LCOE和NPC分别记录为0.396美元/千瓦时和8,966,700美元。 NPC分别。基本案例(发电机)记录的LCOE为0.412美元/千瓦时,OC值为345美元,998,初始成本为454,256美元。获得的结果都相对高于加纳家庭消费者当前的能源成本,但是敏感性分析表明,当某些参数(例如燃料成本,折扣和通货膨胀率)发生变化时,可以降低LCOE。这表明,当当权者创造了必要的投资环境时,便可以进行此类项目。
