Collaborative energy management system control method based on source load storage

The invention discloses a collaborative energy management system control method based on source load storage. The method is characterized in that firstly, a current main power type of a system is determined, the control strategy used is different when the main power type is different, real-time economic optimization control is performed through only relying on the current output power of each photovoltaic system, an energy storage system, a load system and a diesel engine system in a microgrid system, no long-term optimization algorithms such as prediction and optimization scheduling are needed, and thereby long-term scale energy management system software investment cost is saved. The control method is advantaged in that under the premise of ensuring stability of the system, the photovoltaic system is utilized to maximize power generation and reduce use of the diesel engine system, not only can stability of the system be guaranteed, but also the system has certain economic benefits. 本发明公开了一种基于源荷储的协同能源管理系统控制方
