Information framework of optimal reactive power dispatch (ORPD) and the essential characteristics of coordinated reactive power optimization (RPO) in multi-area large-scale power systems are introduced in this paper. We consider that the change of optimal solutions (control settings) cannot be captured by simply using an equality constraint of the boundary values as which the voltages at boundary...
An adaptive particle swarm optimization(APSO) algorithm is presented to solve the problem that the standard particle swarm optimization(PSO) algorithm is easy to fall into a locally optimized point, where inertia weight is nonlinearly adjusted by using population diversity information. Velocity mutation factor and position interchange factor are both introduced. The APSO algorithm thus improves its...
This paper take predictor-corrector interior point method and branch-bound method applied in reactive power optimization. Prediction-corrector interior point method for global optimization, and branch-bound method to deal with discrete variables (transformer tap and capacitor, reactor switching group number). To the reality, this paper take minimizing loss of network as objective, through the IEEE14-bus...
