The principle of the general coordination controller to realize the real-time complementarity of the AC power supply and the new energy power supply is as follows:

(1) Working in the mode of maximizing the utilization of new energy, judge the voltage and current collected at the outlet of the DC/DC module: if the voltage is lower than 90% Un and the PWM duty cycle of the DC/DC module is greater than 98%, If the power of the new energy power supply is insufficient, the AC/DC module will be turned on, and the AC power supply will be rectified in time to ensure the continuous power supply of the DC load; if the voltage is higher than 110% Un and the PWM duty cycle of the DC/DC module is lower than 50%, Indicates that the DC load is small, and the new energy power supply is not fully utilized, then the DC/AC module is turned on, and the excess DC power is inverted and used in grid connection; other situations are normal working conditions, the AC power supply supplies power for the AC load, and the new energy power supply is DC load power supply, AC/DC module and DC/AC module are not working.

(2) Work in the UPS mode, that is, the uninterruptible power supply mode, and judge the voltage and current collected at the outlet of the DC/AC module. If the voltage suddenly drops to 0, it means that the AC power supply is disconnected, and the DC/AC module is turned on. After inverting DC power, it supplies power to important AC loads to ensure uninterrupted work of important equipment.

The working process of the application system of the present invention is:

1. First access the transmission medium provided by the network provider. The communication router implements functions such as dialing up to access the Internet, automatically assigning IP addresses, and generating wireless networks, and provides network services for the user's communication terminals and the general coordination controller.

2. The general coordinating controller accesses the remote server through the Internet network, and the remote user terminal accesses the remote server through the Internet network, so as to achieve the remote interaction between the remote user terminal and the general coordinating controller, that is, the user can remotely monitor the working status of the home trustworthy router in real time .

If it is not connected to the Internet network, the user can only monitor the Nengxin router locally through the touch screen. The human-computer interaction is completed by the touch screen, which displays the working status of the Nengxin router and completes the control commands for the user to turn on and off all DC loads and AC loads.

3. The user sets the Nengxin router to work in the mode of maximizing the utilization of new energy through the remote user terminal connected to the Internet or by touching the display screen. The working process is as follows:

When there is no access to new energy sources or the power of new energy sources is insufficient, part of the power frequency AC power connected to the grid is directly supplied to the local AC load, and part of it is rectified by AC/DC to provide reliable power supply for the DC load.

After the new energy power supply with unstable voltage and current is connected, it will be converted into a stable DC power supply by the DC/DC module to supply power for the DC load; and when the DC power is redundant, that is, it cannot be consumed by the DC load in a short time, try not to discard it In the case of electricity wasting energy, the DC is inverted through DC/AC to provide part of the power for the power frequency AC load.

4. The user can set the Nengxin router to work in UPS mode through the remote user terminal connected to the Internet or by touching the display screen. This mode is suitable for remote areas or places with important electrical equipment. The working process is as follows: Judging the working status of the AC power supply, it can be divided into two types: normal supply and disconnection. When the AC power supply is disconnected, the new energy power supply is connected and an alarm is issued to continue to supply power to important electrical equipment for a period of time, to protect important electrical equipment from instantaneous power loss, and to save important data in time for users.

In the above 3 and 4, after the user selects the working mode, the real-time complementation of the new energy and the AC power supply and the UPS working process are automatically judged and completed by the general coordination controller without user intervention.

5. This system monitors the smart socket connected to the wireless local area network generated by the router through wireless connection, collects and forwards the electrical energy usage information uploaded by the smart socket, and forwards the control command from the remote user terminal to the smart socket.
