IMPROVING VOLTAGE PROFILE AND ENERGY EFFICIENCY IN RDS USING GAMS-BASED CAPACITOR LOCATION AND SIZING

Abstract

The need for reducing active power loss in radial distribution systems (RDS) has become paramount
as global power consumption continues to rise. This paper presents a new approach using the Generalized
Algebraic Modeling Systems (GAMS) software to find the optimal location and sizing of capacitors in RDS.
The approach converts the problem into a mixed integer nonlinear program (MINLP) and solves it using
MINLP-SBB Solver. The effectiveness of the approach is demonstrated by testing it on an IEEE 10 bus RDS
and comparing the results with other optimization techniques. The approach is found to be both efficient and
accurate, providing better results in less execution time. The proposed method significantly reduces power
loss, enhances the voltage profile, improves power factor, and ultimately enhances system stability, making it
safer to operate. The paper provides a detailed explanation of the problem formulation and necessary
mathematical models required to describe the system. The approach has broad applications in the power sector,
and its use will result in significant energy savings, making it an essential tool for power system engineers and
researchers.
