| Abstract |
In this paper, a global measurement-based voltage and reactive power control algorithm using a linear equation is proposed. For linear optimization, the voltage control characteristics of the voltage controllers of the distribution system are expressed in a linear form. It was divided according to the characteristics of each control device and expressed in a linear expression, and the final voltage was expressed as the sum of each control device from the principle of superposition. The voltage equation expressed as a linear expression was formulated as a quadratic programming method (QP). The optimal solution was derived using the mixed integer quadratic programming (MIQP, Mixed-Integer Quadratic Programming), which is a mixed integer nonlinear programming (MINLP), for the objective function expressed by the quadratic programming method. The proposed algorithm was verified through simulation |
