摘要

本文讨论了凯安赫尔电力系统(KPS) 9种不同规模的光伏(PV)和锂离子电池储能系统(BESS)组合在负荷需求峰值变化情况下的能量和成本比较。利用已有的90kW柴油发电机(DG)对9个光伏与BESS组合进行建模，并对DG运行、光伏弃风和蓄电池流能值进行仿真。然后使用安装成本(IC)、柴油燃料成本和能源收费成本对这三种能源进行了成本比较分析。在此之后，研究扩展到20年的时间周期，以获得更完整的系统生命周期成本估算。模拟的能量损失和系统成本在PV和BESS规模增加和负荷需求峰值转移时显示出最有利的值。模拟结果还确定了增加尺寸和转移负载需求峰值的组合几乎没有区别。

PV and Battery Sizing and Cost Study for Small Remote Islands Considering Load Demand Peak Shift

This paper discusses energy and cost comparison for 9 different combinations of Photovoltaic (PV) and Lithium-Ion Battery Energy Storage System (BESS) sizes with load demand peak changes for the Kayangel Power System (KPS). 9 PV and BESS combinations were modeled with the existing 90kW Diesel Generator (DG) and simulated while analyzing the kWh energy values of DG operation, PV curtailment and battery power flow energy values. A comparative cost analysis was then conducted on these 3 energies using Installation Costs (IC), diesel fuel costs and energy charge costs. Following this, the study was expanded to a 20-year time period for more complete system lifetime cost estimations. Simulated energy losses and system costs showed mostly favorable values during increased PV and BESS sizes and shifted load demand peak. Simulation results also identified combinations where increased sizing and shifted load demand peak made little difference.
