| Abstract: | As multi-infeed HVDC greatly influences the safe and stable operation of hybrid AC/DC system, a method is proposed to quantitatively calculate the system voltage interaction factor and average voltage interaction factor between HVDC systems in hybrid AC/DC system. Furthermore, a reactive-power planning method considering the voltage interaction among HVDC systems is proposed, which takes the minimum voltage interaction as the objective of its upper layer while the minimum power-loss and minimum investment as the objectives of its lower layer. Simulation and analysis for IEEE 39-bus extended system show that the proposed reactive-power planning method improves the voltage stability of hybrid AC/DC system. |
