Abstract |
Increasing renewable energy resources can lead to critical stability problems in power systems. Specially in Korean power system, since the power generation complex is concentrated on the coast, there are constraints on transmitting to the load. If a connection of renewable energy resources near generator buses continues to grow, specially in the east cost, transient stability problems may arise due to shortage of transmission lines. Therefore, it is necessary to evaluate how much renewable energy access at each site can affect the power system by some stability index such as critical clearing time. This paper shows how to assess or calculate the margin of dynamic stability and verify the methodology through assessment of a practical power system. Based on the methodology, this paper analyzes the practical system and draws conclusions. |
