Abstract

Received Sep 9, 2020 Revised Oct 31, 2020 Accepted Nov 9, 2020 This paper proposes the calculation of the simple levelized cost of electricity of PV and battery energy storage system for supporting the investment decision of the EV hybrid charging station. The paper introduces the problems of EV charging against the grid power system. Thus, the hybrid charging for EV is suggested. The study provides an architecture of the hybrid EV charging station along with the factor impacting the EV infrastructure for acknowledgment. The cost elements of the station are presented to address the benefits of the investment. Besides, the profit is mainly from the margin of the electricity price, therefore, this study compares the electricity cost of PV and PV equipped with a battery with the commercial on-peak electricity tariff. The results show that the charging cost contributed by PV alone has the lowest amount throughout the study period year 2020 – 2030. In contrast, the hybrid charging cost contributed by PV and battery has a higher value than the on-peak tariff during 2020 – 2025 but it is lower afterward. The result supports the feasibility of charging an EV by solar power and the hybrid power system in the future.

采用光伏和电池储能系统的电动汽车充电的简单平均电力成本:泰国案例研究

本文提出了光伏和电池储能系统的简单平准化电力成本计算，以支持电动汽车混合动力充电站的投资决策。介绍了电动汽车对电网充电的问题。因此，建议电动汽车采用混合充电。本文给出了混合动力电动汽车充电站的体系结构，并对影响电动汽车基础设施的因素进行了分析。提出了车站的成本因素，以解决投资的效益。此外，利润主要来自于电价的利润，因此，本研究将光伏发电和带电池光伏发电的电力成本与商业上网电价进行比较。结果表明，在2020 - 2030年的研究期内，仅光伏发电所贡献的充电成本最低。相比之下，2020 - 2025年期间，光伏和电池的混合充电成本值高于峰值电价值，但之后低于峰值电价值。该结果支持了未来太阳能和混合动力系统为电动汽车充电的可行性。
