Abstract
This project addresses the critical challenge of maintaining power grid stability under the
pressures of intermittent renewable energy integration and dynamic load demands. The primary
objective is to design, simulate, and implement a single-phase grid-tied inverter capable of
controlling active and reactive power to mitigate overvoltage issues. The system features a full-
bridge topology controlled by an STM32 microcontroller, employing Sinusoidal Pulse Width
Modulation (SPWM) and a closed-loop current control strategy.
A real-world case study using CYME software identified critical overvoltage nodes, validating
the necessity of smart inverter functions such as Q(V) control. The control logic was verified
through LTspice simulations, confirming unity power factor operation and low harmonic
distortion. Practically, a hardware prototype was assembled, featuring isolated sensing and gate
drive circuits. Experimental results verified the microcontroller's ability to generate precise,
synchronized control signals, laying the foundation for a robust smart inverter capable of
enhancing grid resilience.
