Abstract: Residential microgrids integrating renewable energy sources and electric vehicle backup play a pivotal role in a step towards sustainable energy for homes. Effective energy management and seamless power flow control are essential for ensuring stability and reliability in both standalone and grid-connected modes. However, the nonlinear dynamics of power converters necessitates advanced control strategies. Sliding Mode Control (SMC) offers robustness but suffers from excessive chattering, while super-twisting SMC (STSMC) reduces chattering but has limitations such as wind-up and restricted dynamic range. To address these challenges, we propose a condition-based integral terminal super-twisting sliding mode controller (CBITSTSMC). The controller gains are optimized using an improved Grey Wolf Optimization algorithm, with global asymptotic stability verified via Lyapunov analysis. MATLAB/Simulink simulations demonstrate that the proposed CBITSTSMC outperforms conventional SMC and STSMC based on key performance metrics. Real-time validation using a controller-in-the-loop setup with the C2000 Delfino MCU F28379D further confirms its effectiveness for practical deployment.
