Vertical facade PV installation to optimize microgrid system on high rise EV parking lot with AC and DC charging station

As Electric vehicle (EV) emerges as a trending transportation mode in developed countries, EV charging stations facility has been installed widespread in many places from urban to suburban area. Installed charging station can be in the form of individual parking slot in the owner residence or massive parking lot in a community area. Commonly, parking lot has been built on the ground and consumes a large area. A parking lot can be transform into high rise parking lot for having higher parking capacity with less ground area needed. This paper will discuss about high rise parking lot which have additional surface for better solar radiance capture rather than on-the-ground parking lot. The building was designed to be able to support electric vehicle (EV) both in alternating current (AC) and direct current (DC) type depends on EVs' energy storage systems. Microgrid architecture was implemented to facilitate the charging process and also to incorporate local power resource i.e. solar power. Designated photovoltaic installments are proposed to optimize the microgrid in the vertical surface of the building. This facade installment should be controlled in one building energy management system (BEMS) and improved the performance of the microgrid. The PV will help the building in decreasing its dependency to the utility grid and increase its profit with no longer spend expenditure on high cost electricity.
