The new method assigns the adjustment command of PV monitoring main substation to different intelligent with an allocation algorithm by adopting hierarchical control regulation way, then all intelligent regulating units adjust at the same time to achieve the power regulation of the entire PV station and send the power to the master station. This system can reduce the burden of master station and improve the regulative speed and precision effectively, which has good practical value for distributed PV station. Key words: distributed PV station; intelligent regulating system
