Impact of STATCOM in Stabilizing Disturbed Microgrids Powered by Wind Energy

Abstract

Electricity distribution systems face significant challenges, including energy losses, voltage instability, and the intermittency of renewable energy sources like wind and solar power. To enhance power quality and stability, advanced compensation devices such as Static Synchronous Compensator (STATCOM) are integrated into power networks. This paper investigates the impact of STATCOM on voltage regulation and wind energy integration within a 30 kV medium-voltage network at an interconnection point comprising a load, a renewable energy source, and an AC grid. A STATCOM-based control strategy is implemented to dynamically adjust voltage by injecting or absorbing reactive power, ensuring a stable power supply under various scenarios, including wind variations, load fluctuations, and short-circuit faults. Simulation results confirm that STATCOM effectively maintains voltage amplitude at its reference value, stabilizes the system during disturbances, and ensures continuous energy availability. By mitigating voltage variations and supporting renewable energy integration, STATCOM enhances overall power system reliability and quality.
