#### 5.5.3 Analysis of Hybrid-Microgrid-Based EV Charging Infrastructure  
An analysis of AC- and DC-microgrid-based EV charging infrastructure can aid in comprehending the potential benefits and drawbacks associated with each type of infrastructure. DC charging offers faster charging speeds and a higher power output, enabling vehicles to be charged more quickly. On the other hand, AC charging requires a longer duration to fully charge a vehicle. DC charging offers faster and more efficient charging for vehicles due to its ability to deliver higher power levels and shorter charging durations. AC charging is frequently preferred due to its simpler wiring requirements and seamless integration into the existing electric grid infrastructure, making installation a straightforward process. However, due to the higher power requirements, AC charging also entails the need for additional infrastructure. In addition, it is worth noting that AC charging may not provide the same level of power as DC charging, which can result in reduced charging speed and effectiveness for vehicles. In contrast, the establishment of connections and infrastructure for DC charging is more intricate, although it provides expedited charging and enhanced power capabilities. The charging speed and efficiency of vehicles may be enhanced. However, the implementation of DC charging requires a significant investment in infrastructure, resulting in potential high costs. Additionally, compatibility issues may arise with existing equipment within the electric grid. In the EV sector, the integration of AC- and DC-microgrid-based EV charging facilities can provide significant advantages. When selecting the infrastructure type, it is important to consider the specific requirements of the application. DC charging is the optimal option when there is a requirement for the rapid and efficient charging of a vehicle. Alternatively, AC charging may be the optimal solution when the application necessitates a less intricate cabling system and seamless integration into the existing electrical grid infrastructure. Table 17 displays the overall benefits and drawbacks of EV charging infrastructure powered by a hybrid microgrid. \begin{table}
