Optimized Technique of Fractional Order- Integral Sliding Mode for Hybrid Renewable Energy Sources Integrated to Micro-Grid System

This paper presents an optimized method using Fractional Order and Integral Sliding Mode Control (FO-ISMC) to improve power quality in micro-grid-connected PV and wind systems. The DC side integrates PV and wind sources, while the AC side features a three-phase VSI connected to the grid via an RLC filter, supplying linear loads. FO-ISMC manages the DC link voltage and ISMC controls current loops to reduce harmonics and optimize power delivery. MPPT with Incremental Conductance maximizes power under varying weather. MATLAB/ Simulink validation shows the proposed method outperforms conventional PI regulator in terms of performances, robustness, and efficiency.
