Due to the interaction between AC and DC systems, the multi-DC feeding receiving-end power grid is prone to have safety and stability problems. Reactive power equipment can improve the transmission capacity of power grid at the same time avoid voltage drop which is gradually applied in receiving-end power grid. In this paper, a polytype dynamic reactive power equipment coordination optimization model based on static and transient voltage stability is proposed, which can be used for dynamic reactive power planning of receiving end power grid to satisfy the safety and stability standards and the minimum investment scheme limited by installation conditions. The guiding significance of the model for dynamic reactive power planning is illustrated by an example of the reactive power planning for the south Suzhou power grid in East China.
