Description

technical field

[0001] The present invention relates to the field of dispatching control of power systems, in particular to an AC / DC hybrid power grid considering the characteristics of a voltage source converter (Vehicle Stability Control, VSC) and the reactive power support of a double-fed induction motor (Double Fed Induction Generator, DFIG) Dynamic reactive power optimization method and system. Background technique

[0002] Vigorously developing new energy is the only way for all countries to ensure energy supply security, respond to climate change, control smog, and achieve sustainable development in the future. Due to the reverse distribution of new energy resources and consumption centers, UHV DC projects must be used for long-distance power transmission to realize the allocation and consumption of new energy across the country. With the commissioning of a series of UHV DC projects, the characteristics of "strong direct and weak alternating current" of the cross-reg...
