Coordination and Optimization Of HVDC Modulations Using Chaotic Optimization Algorithm in DC/AC Power System

A Chaotic Optimization Algorithm (COA) is applied to integrated AC/DC hybrid power system in which the multi-infeed DC power transmission system is included, and the research on coordination controls among the HVDC modulations has been investigated in this paper. Chaotic Optimization Algorithms, which have the features of easy implementation, short execution time and robust mechanisms of escaping from local minima, is a promising tool for engineering applications, parameters tuning problem of the HVDC modulations is converted to an optimization problem which is solved by a chaotic optimization algorithm based on Lozi map. Taking the planned power network in the South Power Grid for example, the effectiveness and the robustness of the presented method are verified.
