An independent power supply system reliability microgrid load reduction method

The present invention provides an independent power supply system reliability microcell load reduction method. The system is divided into individual micro mesh regions different feeders; master access centralized power, connected with the different regions via the transformer feeder; independent piconet system further comprises a generator of renewable energy or energy storage device and, provided the transformer the bus connected to the high pressure side or disposed in the interior region of the feeder; piconet is determined independently of the power supply system can interrupt load, and the sum or from small to large to be constructed from a lightweight heavyweight order of importance according to the load cut sheet active load . In the case of renewable energy is random, intermittent characteristics, independent piconet system design can make full use of renewable energy sources, while ensuring the reliability of the system power supply.
