Voltage Stability Improvement and Loss Minimization by Optimal Placement of STATCOM using Teaching- Learning Based Optimization Technique

Abstract

In the modern power system voltage instability is the most prevalent issue which occurs continually and mandates the system operator to find the remedy in order to have the efficient and reliable operation of equipment con-nected to the system. This literature emphasizes on the voltage instability issue of power systems and also an approach which can overcome the problem when-ever the system is subjected to an aforementioned problem which is usually ac-complished by deploying compensation device of suitable size. In this paper, teaching learning-based optimization technique is used to find the appropriate size of the compensatory device, whenever the voltage violation occurs due to the increased demand for active power as well as reactive power in the system. dv/dq index is preferred to find the location of compensatory device allocation. In this literature, STATCOM is used as a compensatory device and this ap-proach is validated for IEEE 30 bus system on the MATLAB platform.
