A SOFC based autonomous microgrid performance analysis using adaptive PI and PI controller

A methodology based on MCFC (Microgrid connected Fuel Cell) is emphasized in this paper, In order to maintain the DC link capacitor voltage constant a DC-DC Boost Converter has been used which is then given as VSC's input. This paper work communicates a Voltage Control strategy of VSC for the autonomous operation of Microgrid. An adaptive control setup is designed to procure maximal control of parameters. In This type of adaptive controller a PD type Fuzzy Controller is used which helps in auto tuning the Kp & Ki parameters continuously. Disregarding the variation of load and its unpredictability the proposed controller is used to monopolize the parameters of the islanded network. An additional Hysteresis Band Current Control (HBCC) is used which conduces towards the accuracy. The demonstration of the controller is legitimated through simulation studies, which offsets that the proposed controller provides a desired control of system parameters.
