Optimal Placement of DSTATCOM in Electrical Distribution System

Abstract

Currently the electrical energy demand is rising faster way in developing countries like India. As a result, more distribution losses and low voltage profiles in the large and complex electrical distribution systems (EDS). Studies observed that nearly 10-15% of the total generated electrical power is fed on as I2R losses at the stage of distribution level. The consumers voltages have reduced when moved away from the substation and such consumers contribution in distribution losses is more based on associated connected load of consumers. In addition to that voltage stability decreases and maximum loadability margin also reduced in the distribution lines. Subsequently, it will be imperative to improve the capacity of power transmission in EDS. The planning and optimization of compensating device and Distributed Generation (DG) are estimated to improve the reduction of energy losses and beautify the consumer voltage profile in the EDS. The recommended approaches introduce with planning and optimization using simple and fast load flow solution for optimal placements and optimal sizes of the Distribution Static Synchronous Compensator (DSTATCOM) with different optimization methods.
