Abstract: Abstract: - In the deregulated environment, transmission congestion is one major problem that needs to be handled in power system operation. This paper aims to alleviate congestion using the multi-objective load curtailment (MOLC) approach. The proposed MOLC approach optimizes the two objectives simultaneous, namely the security margin and load curtailment cost. The security margin is measured by a presented voltage instability indictor (VSI). A fitting coefficient is adopted to combine the two conflicted objectives. The primal dual interior point method (PDIPM) is adopted to solve the proposed MOLC model. The effectiveness of both the improved PDIPM and the MOLC approach has been tested and proven on the modified IEEE 30-bus system and IEEE 118-bus system. The results obtained show that the proposed technique is able to improve system security while yielding lower cost of load curtailment.
Keywords: Key-Words: - Multi-objective load curtailment, voltage instability indicator, security margin, cost of load curtailment, fitting coefficient, primal dual interior point method
