Optimization of Reactive Power with Both Voltage Profile and Voltage Stability Using Jaya Method

Abstract

The problem of reactive power flow is a complex and difficult because it causes many problems, most notably loss of power, voltage deviation and voltage instability. Therefore, the reduction of these elements was one of the important studies in electrical power systems. The choice of the Jaya Algorithm (JA) was good for this goal because it is a fast, efficient and stable method that gives a global optimization solution in most cases. Thus, it is a method based on only one simple equation. This method is applied to typical electrical grid 30-node of IEEE in order to reduce the total real losses as well as with voltage deviation and the coefficient of voltage stability. Additionally, the reduction of losses and voltage deviation with the coefficient of voltage stability is treated because the decrease in the voltage deviation leads to an increase in its stability index and vice versa, which makes it a multi-objective optimization problem.
