GA for enhancement of system performance by DG incorporated with D-STATCOM in distribution power networks

Abstract

This paper presents the enhancement of voltage profile using distributed generation (DG) incorporated with distribution static synchronous compensator (D-STATCOM) with different load models (DLMs) such as constant power, constant current, constant impedance, composite and reference load models in distribution power networks by using genetic algorithm (GA) from minimization of total real power loss of the system. In this paper, considered the different size of D-STATCOM such as −50 to +50MVAR, −75 to +75MVAR, −100 to +100MVAR, −125 to +125MVAR and −150 to +150MVAR are taken for evaluation of voltage profile of the system buses. The proposed methodology illustrated for IEEE-75 bus test system. This work is very useful for researchers and scientific persons in conjunction with enhancement of voltage profile using distributed generation (DG) incorporated with distribution static synchronous compensator (D-STATCOM) with different load models in distribution power networks.
