Abstract In order to solve instability the interaction among the various DC-modulation and between DC-modulation and PSS in AC/DC 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 between the HVDC modulations and PSS is investigated in this paper. Parameters tuning problem of the HVDC modulations and PSS is converted to an optimization problem which is solved by a chaotic optimization algorithm based on Lozi map, Thus under global coordination the damping of the whole system to the electromechanical oscillations in the AC system is enhanced. Taking the planned power network in the South Power Grid for example, the effectiveness, robustness and superiority of the presented method are verified.

Key words： Chaotic optimization Lozi map HVDC modulation PSS nonlinear optimization power oscillation power system stability
