| Descripción: | Congestion management is one of the most important issues for secure and reliable system operations in deregulated electricity market. In most cases, Independent System Operator tries to remove congestion by rescheduling output power of the generators. In this paper, transmission congestion distribution factors based on sensitivity of line real power have been proposed to identify the congestion clusters. The system operator can identify the generators from the most sensitive congestion clusters to reschedule their generation optimally to manage transmission congestion based on generator sensitivity efficiently. The role of thyristor controlled phase angle regulator and Thyristor controlled series Capacitor have been investigated for reducing the transmission congestion cost after locating it optimally in the system based on improved performance index. The effectiveness of the proposed method has been carried out on an IEEE 118 bus system and 62 bus Indian Utility System. Keywords: Congestion zones, Congestion Management, Transmission congestion distribution factors, Thyristor controlled phase angle regulator, Thyristor controlled series Capacitor, Rescheduling, Performance Index, and Sensitivity Index. |
