Distributed photovoltaic power generation energy dispatching system and method

The invention discloses a distributed photovoltaic power generation energy dispatching system and method. The system comprises a distributed photovoltaic battery array, a distributed inverting control system, a sensing network, an electric control system, an energy storage unit, a control center system and a cloud platform energy dispatching center. The cloud computing is introduced into the energy dispatching strategy of the distributed photovoltaic power generating system, firstly, the energy storage unit is used for storing the electricity generated by a distributed photovoltaic power generating system, then, the cloud platform energy dispatching center is used for sending commands to the control center system, and in addition, whether the energy of the energy storage unit is merged into a large electric network or is directly provided for a user load is determined according to the electricity consumption of the user load. Therefore the self organization characteristics of the electric network are favorably enhanced, and in addition, the power transmission and power distribution loss is reduced.
