Microgrids (MG) are distribution systems that contain Dispersed Generations (DGs), Energy Storage Systems (ESS) and loads. Voltage source inverters arecommonly used to connect the generation units to the MG. The demand active and reactive power of the MG is dispatched through these inverters. Without using anycontroller, an increment in active and reactive power leads to frequency and voltage drop respectively. Therefore, droopcontrollers are essential in MGs. In this paper, a microgrid has been modeled and its voltage and frequency behavior in presence of an induction motor and RL load has been analyzed.
