Abstract

This paper presents a novel approach for
economic power flow in multi-terminal AC-DC systems. Unlike the similar AC-DC
power flow studies, real equivalent circuit for the under load tap changer
transformers (ULTCs) of the DC converters are considered in the AC-DC power flow
algorithm. So the study provides real accurate results for practical AC-DC
applications. Economic power flow solution for minimum generation cost is
provided by Genetic Algorithm (GA). The proposed approach is tested on the
modified IEEE 14-bus AC-DC test system. The results show that the proposed
approach is efficient to reach the global optimum point of minimum generation
cost without getting stuck to local minima while satisfying system constraints.

Keywords
