Static centralized and dynamic distributed coordination control system for reactive power/voltage of distribution network

The invention relates to a static centralized and dynamic distributed coordination control system for the reactive power/voltage of a distribution network. The system comprises a static reactive power centralized optimization control subsystem and dynamic voltage distributed control subsystems. On a centralized dispatching side, the static reactive power centralized optimization control subsystem determines a switching strategy for capacitor banks according to requirements on limitation on the switching times of the capacitor banks and changes in a load, controls the capacitor banks, simultaneously detects whether dynamic voltage distributed control succeeds or not, and starts a dynamic voltage centralized control strategy if the dynamic voltage distributed control fails; and the dynamic voltage distributed control subsystems automatically regulate dynamic reactive power compensation devices and transformer tapping joints according to local measured data and the fluctuations of the load and the voltage, and simultaneously detect whether static reactive power centralized optimization control succeeds or not to start a static reactive power distributed control strategy. Compared with the prior art, the system has the advantage that the advantages of centralized and distributed control are fully utilized.
