ETAP Based Analysis of 13-Bus Microgrid

This study proposes a method for islanding a microgrid using a passive islanding system using ETAP software. This method involves detecting anomalous frequency or voltage in the system and improving its stability. Simulations presented in tis study show that the loss of voltage and frequency of a microgrid can lead to a potentially catastrophic effect. It is important that the two components are restored to maintain the stability and reliability of the system. Underfrequency load shedding is proposed to be utilized when the frequency of a microgrid drops below its rated value. It is achieved by reducing the load by taking advantage of the lower frequency of the microgrid. The simulations show how islanding a microgrid can affect its operation in the event of a fault. The study also shows how this effect can influence the stability of the microgrid.
