The invention provides a virtual power plant source network cooperated energy management system for photovoltaic multi-stage access. The virtual power plant source network cooperated energy managementsystem comprises a process layer, a terminal layer and a main station layer, wherein the process layer comprises a primary device which is arranged in a distributed energy power station and used forcompleting analog quantity sampling, on-off quantity input and output and execution of operation control commands, the terminal layer comprises all measurement and control terminals provided with process layer interfaces and completing collection of operating information of the process layer and issuing of control commands, and the main station layer completing various advanced applications and anoverall scheduling algorithm on the basis that collection of the operating information of the terminal layer is completed, issuing global optimization control commands to the terminal layer and finally completing control functions of a virtual power plant. The virtual power plant source network cooperated energy management system adopts an energy management technology, controllable resource and power grid cooperated source network integrated control and scheduling under different operating main bodies are achieved by adopting a comprehensive technical and commercial integrated virtual power plant regulation technology under the local consumption conditions of high-permeability batch-type new energy resources.
