The invention discloses a layered and distributed network voltage regulator control system based on an active mechanism. The layered and distributed network voltage regulator control system based on the active mechanism comprises a reactive voltage controller which faces a single branch, a coordination voltage controller which faces a local area and an initiative power distribution network voltage management subsystem which faces a whole power distribution network. The initiative power distribution network voltage control subsystem determines a voltage control indicator according to a distribution condition of power distribution network active power. When a voltage is beyond a certain limit, the reactive voltage controller locally regulates the voltage which is beyond the certain limit. When the regulation fails, the coordination voltage controller is regulated on the basis of overall considering voltage fluctuations and a batch-type energy source grid connecting and grid separating plan, and voltage beyond limit recover based on the active mechanism is achieved through the coordination of the reactive voltage controller and the coordination voltage controller. Meanwhile, the invention further provides a regulating method which corresponds to the layered and distributed network voltage regulator control system based on the active mechanism. The layered and distributed network voltage regulator control system based on the active mechanism and the regulating method which corresponds to the layered and distributed network voltage regulator control system based on the active mechanism achieve active control of the beyond limit voltage of the power distribution network on the premise of meeting power distribution network constraint conditions.

The present invention belongs to the technical field of community management, and is specifically a smart access control system for an Internet of Things community, including a behavior detection module, an information module, a breeding module, a service module, a daily monitoring module and a connection module; the behavior detection module includes a number plate Unit, face information input unit, contact information input unit, distribution unit, environment detection unit, face recognition unit and comparison unit; the number plate unit is used to formulate a special number plate for pets, and send the formulated signal to people Face information entry unit; the face information entry unit is used to record the face data of the pet owner, and enters the face data into the number plate unit, and sends the entry completion signal to the contact entry unit; the present invention mainly uses Because the existing community access control system cannot manage pets in a unified way, it cannot realize the pets' self-entry and exit, and at the same time, it cannot process the calls of pets in the community.

The present invention provides a power sales deviation management system and its method, which uses a dynamic deviation rate threshold to adjust the power sales deviation, which can avoid the existing problem of unsuccessful transfer, and can be used as an effective alternative to load forecasting for power consumption regulation , reducing the adjustment difficulty, the method of this application is also applicable to users with irregular electricity consumption, thus improving the management range of electricity sales deviation; combined with the existing load forecasting means, the accuracy of deviation control is improved.
