With the recent increase in renewable penetration, the electrical network system has changed greatly in structure, function, and operating characteristics. Recently, inverter-based microgrids working in grid-connected and islanded mode are the prominent sources of power to harness renewable energy. This paper presents a model of a microgrid containing parallel inverters, supported by a millimeter wave-based communication system to provide power to critical loads in an islanded scenario. The communication system is mainly utilized for assisting the power sharing of the inverters. To evaluate the performance of the proposed scheme, a six-bus modified IEEE test system is considered having six inverters and is tested on inductive and capacitive loads for different line impedances. Moreover, the control center of the microgrid has plug and play options to switch on and off inverters during operating and emergency conditions. Furthermore, the performance of the communication network has been thoroughly analyzed in terms of communication latency and bandwidth. Results show that the proposed microgrid model along with modified proportional integral derivative (MPID) allows accurate power sharing among the inverters with minimal fluctuations under different testing conditions for both resistive and reactive line impedances. The smooth transition from grid-connected mode to islanded mode shows that the designed system can ensure power availability during emergency conditions.
