摘要

In this chapter, the algorithm is used to locate the weak link of the power system, and then the strategy of voltage and reactive power optimization in the low-voltage area is put forward. Under this strategy, the compensation degree can be located quickly, and the voltage can be optimized so that the coordination of reactive power compensation capacity and compensation position can be considered. Through the simulation analysis of the actual power grid, the control strategy proposed in this chapter has a good control effect on the regional voltage stability, and provides a guiding basis for the economic dispatching of the power grid.
