A multi-objective approach to transient and voltage stability control constrained OPF YJLPQ
In this paper, a novel multi-objective framework is proposed for constrained optimal power flow problem to improve voltage and transient stability and minimize the active power loss of the system during pre-contingency and post-contingency intervals. The proposed approach uses corrected transient energy margin (CTEM) and voltage collapse proximity index (VCPI) simultaneously to improve system stability. Also active power loss is incorporated in the model. The developed multi-objective programming is solved by ε-constraint method to demonstrate effectiveness of the proposed model.
