Since this project focuses on the implementation of EVCS in existing QU parking areas, the outcome should compute the percentage of used parking by EVCS from the overall parking. Based on the collected data, there are about 5000 parking slots distributed around the QU campus. However, there is one restriction that makes this study not to cover all parking areas in QU, and concentrate on parking slots inside buildings or nearby buildings with sufficient and accurate information (without missing data) on their substations. Accordingly, the parking areas selected for this preliminary study are the Multi-floor Car parking, male student housing, female student housing, pharmacy college, medical college, and office building due to the availability of their substation’s information provided by the QU-FGSD.
Regardless, of the limitations imposed by the substations’ spare capacity, additional PV power generation is the key to expands the number of EVCS in the parking area. The purpose of having a PV system in the design is to diminish the reliance on the grid power and keep the spare power for any future additional load of QU. It is also a contribution toward making QU campus a greener transitioning toward zero-carbon campus. Therefore, these buildings were chosen to integrate the EVCS and are used to calculate the active area of the parking shading and their roof where PV modules can be installed. The calculation of areas of the parking shading and building roof helps to find the number of PV modules need in that area and the power generated from them. The number of PV modules to be installed with a fixed tilt angle, are obtained with the PVSYST software [1]. The location of each building is a requirement in PVSYST software to find the optimum tilt degree of solar panels.
Additionally, this study investigates the effect of the integration of EVCS in the QU network. Hence, the study should operate though three different scenarios, which are the K1, K2, and K3, as explained in Table 1.
