Techno-Economic Evaluation of In-City EV Charging Station Empowered by PV-based Microgrid in Various Solar Irradiation Levels

The transition energy to ultra-low and zero vehicle emissions brings over a challenging situation to develop public electric vehicle charging stations (SPKLU) infrastructure. A plug-in electric charging infrastructure solar panel supported microgrid might offer a potential solution. An integrated microgrid with PV sources, battery charging, and EVs has been designed using a simulation that can be mobilized through order to meet the needs and expansion load. This research will be focused on the technical evaluation and financing scheme comparation to define the best solution for in-city EV charging station. Using techno-economic approach, the project implementation criteria at PLN can be met by the financial indicators resulting in IDR 17 billion NPV higher than 0, with 11.2 years payback period less than 15 years, and 13.64% IRR on equity higher than current cost capital (7.1%). Finally, the result indicate that the solar irradiation value and price of photovoltaics have a significant impact with effectiveness and design of EV charging station empowered by PV-based microgrid in three different Indonesia urban areas (Jakarta, Bandung, and Denpasar) with level of radiation in each areas.
