Large-Scale Renewable Energy Penetration Impact on System Stability

Renewable energy sources integration has expanded dramatically in many countries in recent years. Existing synchronous generation fleets would most likely be displaced as a result of this significant capacity penetration. As a result, the system may experience significant instability issue, thereby lowering network service quality. This study analyses the adversely impact on the power system in the context of significant wind penetration to better understand these challenges, i.e., voltage and angular stability. The network used in this research is a rough representation of a real power system. Some traditional techniques such as renewable energy curtailment and system reinforcement to improve the system stability are also studied
