Control of converter fed microgrid using fuzzy controller

This paper presents fuzzy controller for voltage-frequency control scheme for microgrid in islanding operation. The proposed scheme of fuzzy based voltage-power/frequencyre-active power (VP/FQ) sets the real power output to regulate the microgrid voltage and the reactive power output to regulate the frequency. This supervisory control scheme allows the voltage source converter(VSC) with standard inductor interface and dq-frame current control in islanding mode in the instantaneous synchronization operation. The results demonstrate that the proposed approach perfume well and has a significance for the control of inverters in microgrid.
