Impact of hybrid solar and wind distributed generators on transient stability of captive power systems

Year: 2026

Type: article

Abstract: This paper investigates the impact of solar and wind distributed generators on the transient stability of a 39-bus industrial power system. The system is analyzed under different configurations, including wind-only, solar-only, and hybrid DG integration. Critical Clearing Time (CCT), active power, and reactive power are used as performance metrics. The results show that DG integration improves system stability compared to the baseline case. Specifically, the CCT increases from 0.018 s (without DG) to 0.0248 s with wind DG, and up to 0.3168 s with solar DG. The hybrid configuration results in a CCT of 0.0297 s. These results indicate that solar DG provides the highest improvement in transient stability due to better voltage support characteristics. The study highlights the importance of DG type and placement in improving stability and provides insights for industrial power system design.
