Abstract: A novel control strategy is developed for High Voltage DC (HVDC) links to improve oscillatory stability of interconnected power systems. An 'area' principle is proposed for controller design to damp AC tie power oscillations by increasing the oscillatory 'deceleration area'. Exploiting fast control capability of HVDC link, a fuzzy-rule is adopted to smooth the power transition for reducing power 'shock' to power system. The strategy also incorporates adaptive control techniques to prevent tie-link power 'chattering'. Simulation results using the proposed control scheme on two typical power systems are presented. The results demonstrate that significant improvements in both oscillatory and transient stability are obtained.
