DSR design fundamentals: Power flow control

The electrical power sector is facing a crucial issue which is the need to analyse and determine the adequacy of the transmission capacity, and the need for new techniques to increase the capability of transmission systems. Distributed Series Reactance (DSR) control is a new smart grid technology that is primarily being applied to control flows in the transmission system. This paper investigates the use of DSRs to make best use of the additional capacity already existing in long transmission lines. An experiment using 230 kV, 345 kV and 500 kV three parallel transmission lines is performed to determine the fundamentals of DSR design. Several case studies were adopted, in which the three long transmission lines are variously modeled to investigate different line models, and impedance models impact. Observations are highlighted and design considerations are suggested.
