A New Approach for Locating and Adjustment of Phase Shifters

Abstract

Phase Shifting Transformers (PSTs) are powerful tools for controlling power flow in HV and EHV networks. The locating of PSTs in these networks can be considered as an optimization problem with a special objective function. This paper aims at locating of PSTs. The objective function is the transmission losses and PST must be used to minimize this function. To solve this optimization problem, different types of solutions have been presented, which are based on direct or indirect searching methods. This paper presents a new, simple and practical solution, which is a combination of both searching methods.
