Transmission congestion management

Under deregulated environment transmission congestion is managed in many different ways. Most utilities create; update their own rules of how the congestion is managed. The common output in most cases is temporary congestion relief and higher costs of energy to the end user. Transmission congestion problem is studied from different aspects, i.e. congestion relief, energy price reduction, congestion costs and cost recovery or payback period. The proposed method is tested on an 11 bus 380 kV real system. An analysis is carried out in order to evaluate the payback period for permanent congestion removal.
