“…The wind farm module has a permanent magnet synchronous generator (PMSG) which is an independent power generation machine. Even the wind farm uses boost converter but with a diode bridge rectifier between PMSG and the converter for AC-DC conversion [9], [10]. The battery module comprises of a bidirectional DC-DC converter which has the capability to store and extract power from battery during excess and deficit conditions respectively.…”

A multi renewable source micro-grid system has many power quality issues when it is operated in grid islanding condition. During grid connected mode the voltage and frequency of the system will remain stable for small disturbances like load changes or environmental changes. During these sudden variations in the system, the grid supports the load maintaining the system stable. In this paper a droop control is introduced for the renewable source module 3-ph inverter during standalone mode supporting the load. For detection of grid islanding, an active islanding detection control is adopted which makes the 3-ph inverter to shift from synchronous reference frame (SRF) control to droop control. The performance of the droop control is improvised with fuzzy interference structure (FIS) module replacing the conventional proportional integral and derivative (PID) control. A comparative analysis is done in this paper with different controllers in droop control scheme using matrix laboratory (MATLAB) Simulink software. Stability analysis is carried out on the system determining the voltage and frequency fluctuations during grid disturbances. There is an improvement in load compensation, voltage ripple, voltage magnitude, frequency ripple and settling time with the introduced fuzzy droop controller.

“…Thus, the PV cannot correctly supply the load [12]. Therefore, using a DC converter connected to a DC Microgrid produces a ripple-free output voltage and outputs current [13,14]. The voltage generated by the PV is used to charge the battery.…”
