The new real-time control system of reactive power optimization

This paper uses non-linear programming optimal power flow algorithm with slack constraint to analyze reactive power real-time optimization problems in actual grid. And considering the effect of control action sequence on the optimal control effect, the control strategies of the reactive power real-time optimization control system are improved. The control action sequences in normal and failure circumstance are separately determined based on the control variables' active power loss control sensibility and voltage control sensibility, effectively avoiding the system oscillation caused by control variables changing at the same time. The application on IEEE-30 bus system verifies effectiveness and practicality of the algorithm and control strategy in this paper.
