Abstract

In this Reactive power optimization is a nonlinear, multi - variable, multi - constrained programming problem, which makes the optimization process multifaceted. In this paper, based on the characteristics of reactive power opti mization, a mathematical model of reactive power optimization, including comprehensive concern of the practical constraints and reactive power regulation means for optimization, is established. Reactive Power reduces power system losses by adjusting the re active power control variables such as transformer tap - settings, generator voltages and other sources of reactive power such as capacitor banks. Reactive Power provides better system voltage control resulting in improved voltage profiles, system security, power transfer capability and overall system operation. Also Differential Evolution (DE) Algorithm has been studied, and the technique based on improved DE Algorithm for reactive power is going to be taken in this paper Optimization for the IEEE 14 - bus and IEEE 57 bus system proves that the improved DE algorithm used for reactive power optimization is valuable. The algorithm is simple, convergent and of high quality for optimization, and thus appropriate for solving reactive power optimization problems , with some application view
