Micro-grid'source-load-storage 'cooperative interaction control system and micro-grid'source-load-storage' cooperative interaction control method

The invention provides a micro-grid'source-load-storage 'collaborative interaction control system and method. The system comprises a master controller, a grid side monitoring unit, a micro-grid side monitoring unit and an energy storage unit, the power grid side monitoring unit is used for measuring a power grid three-phase current signal and a power grid three-phase voltage signal and transmitting the signals to the master controller; the master controller sends out a switching-off command or a switching-on command according to a detected current signal and a detected voltage signal of the power grid, so that the micro-grid enters a grid-connected operation mode or an off-grid operation mode; the micro-grid side monitoring unit is used for measuring a micro-grid current signal and a voltage signal and transmitting the signals to the master controller; and the master controller stores redundant electric energy generated by the new energy power generation device to the energy storage unit according to the dete
