Abstract
: This paper presents a vigorous control design and a robust controller for a Multifunctional grid interconnected inverter [MFGII] beneath disturbed load conditions. This MFGII controller algorithm uses DQ theory to assess the unacceptable parts of grid current such as harmonics, and required load reactive current. This decoupled method of control design makes normal Grid interconnected inverter to MFGII and also helps in reducing the computational burden which further makes the system more robust. Furthermore, Adaptive Fuzzy sliding mode control (AFSMC) algorithm prepares the system sturdy and effective in improving the dynamic performance during uncertainties. Henceforward, settling time and overshoot are reduced with fast dynamic response. The MFGII infuses the RES to grid at PCC which in addition to Real power injection also provides reactive power compensation, balance the load and mitigate harmonics. The results obtained from FOSMC are compared with AFSMC under the variation of solar irradiation and load.
