Design and Analysis of a PMSG-Based Wind Energy Conversion System for Grid Integration with Enhanced ReliabilitY

This paper presents the design and analysis of a Permanent Magnet Synchronous Generator (PMSG)-based Wind Energy Conversion System (WECS) with emphasis on grid integration and reliability enhancement. The proposed system consists of a wind turbine, PMSG, back-to-back converters, maximum power point tracking (MPPT), phase-locked loop (PLL) synchronization, and an LCL filter for power quality improvement. A Perturb and Observe (P&O) algorithm is employed to maximize power extraction under variable wind conditions, while the Grid-Side Converter (GSC) is controlled through dq-axis decoupled current regulation to maintain DC-link voltage and ensure grid code compliance. Simulation results in MATLAB/Simulink demonstrate stable operation with high efficiency, low harmonic distortion within IEEE 519 standards, and improved fault ride-through (FRT) performance. The system maintains reliable synchronization, provides reactive power support during disturbances, and ensures consistent active power delivery to the grid. These results confirm the suitability of PMSG-based WECS for modern grid integration with improved efficiency and resilience.
