Shifting trend of power system from non-renewable resources to renewable have caught a great interest in establishing more microgrids to meet all the global concerns of fuel exhaustion, clean energy, and climate change. Easy integration with existing traditional power plants with a specialized control system has make microgrids a hot topic in modern power system research.
Microgrids (MG) have been widely accepted as a viable solution to improve grid reliability and resiliency, ensuring continuous power supply to loads. However, to ensure the effective operation of the Distributed Energy Resources (DER), Microgrids must have Energy Management and Control Systems (EMCS).
A droop control has been identified as a potential solution of the requirement of Plug and Play feature of microgrid operation. This control scheme provides a without communication control over power transfer, high flexibility, and high reliability for different-capacity microgrid structures. However,
The reference frequency is provided by the grid during grid-connected operation. However, this should be generated by the microgrid control system (e.g., by using the droop control strategy) during off-grid operation. This control strategy uses two methods for DG resources using power electronic inverters.

This paper describes and evaluates the feasibility of control strategies to be adopted for the operation of a microgrid when it becomes isolated. Normally, the microgrid operates in interconnected mode with the medium voltage network; however, scheduled or forced isolation can take place. In such conditions, the microgrid must have the ability to operate
