Abstract
Microgrids rely on power electronic con- verters to integrate renewable energy sources in a controlled and reliable way. This project focuses on the design and evaluation of grid-following inverters for a microgrid comprising wind power, pho- tovoltaic generation, and battery energy storage. An energy-based model of the microgrid is developed to describe the interaction between generation units, storage, and the load. Based on this model, grid- following control structures for the wind and solar inverters are implemented in MATLAB/Simulink and assessed through simulation. The evaluation focuses on active power reference tracking, current control behavior, and power quality, with particular emphasis on current reference tracking and harmonic distortion. The results show that the inverters can track their power references with sta- ble dynamics and low steady-state error. The injected currents remain balanced and close to sinusoidal, with total harmonic distortion within commonly accepted lim- its. A limited set of HIL tests is included to provide initial insight into practical im- plementation aspects.
