Abstract

This study analyses the feasibility of the Sea floating PV (SFPV) system utilization in conjunction with Diesel generator (DG) to supply the resorts at Small Kei Island, Southeast Moluccas, Indonesia. The SFPV system uses off-grid scheme with a specific scenario that is by dividing the battery into three equal parts which are used interchangeably in order to reduce the fluctuation of the output power generated by DG at once to meet the daily load requirement for 24 hours. The impact is the battery charge cycle changed to twice in three days, thus the battery life will increase to 1.5 times longer. In this study, the economic analysis is done with the loan interest of 10% and the operating time for 25 years. With electricity tariff of 1 USD/kWh obtained the most feasible and profitable combination of capacity of DG and SFPV systems is 130 kW and 20 kW respectively. The combination yields the duration of PBP for 9 years 0 months and 9 days, NPV of 36,545 USD, IRR is 11.65%, and PI ratio is 1.016.

印尼偏远地区居民用电海上浮动光伏/柴油混合动力电厂电池布置方案的技术经济分析(以摩鹿加群岛东南部小基岛为例)

本研究分析了海上浮动光伏(SFPV)系统结合柴油发电机(DG)为印尼摩鹿加群岛东南部小基岛度假村供电的可行性。SFPV系统采用离网方案，其具体方案是将蓄电池分成等量的三部分交替使用，以减少DG一次输出功率的波动，满足24小时的日负荷需求。影响是电池的充电周期改为三天两次，因此电池寿命将增加到1.5倍。在本研究中，以贷款利率为10%，经营时间为25年进行经济分析。在电价为1美元/千瓦时的情况下，DG和SFPV系统最可行和最有利可图的容量组合分别为130千瓦和20千瓦。组合后的PBP期限为9年0个月零9天，净现值为36,545美元，内部收益率为11.65%，PI为1.016。
