Abstract

The invention relates to a cooperative control method and system for a multi-energy supply network of distributed energy stations. Cooperative controllers located at the distributed energy stations collect data of the distributed energy stations, convert the data into universal data information models based on preset rules, and send the universal data information models to cooperative control modules; the cooperative control modules send the universal data information models to energy management subsystems, receive control instructions issued by the energy management subsystems, and send the control instructions to the cooperative controllers of the distributed energy stations; and the cooperative controllers of the distributed energy stations control energy supply scheduling of the distributed energy stations according to the issued control instructions. According to the cooperative control method and system, information flow, control flow and a coordination work mechanism among the modules are established, and equipment and technical support can be provided for realizing multi-spatial-scale energy interconnection and mutual supply of the distributed low-carbon energy stations.

Description

technical field [0001] The invention relates to the fields of automation and power electronics, in particular to a collaborative control method and system for multi-energy supply networks of distributed energy stations. Background technique [0002] The development of various energy conversion equipment (such as combined heat and power, heat pump, electric heating, electric hydrogen production, etc.) provides a means for the coordination and complementarity of multiple types of energy. The distributed low-carbon energy station integrates high-tech and equipment. It is a new type of energy system, which can realize cascade utilization of energy and improve the energy utilization rate of the system. At present, domestic and foreign research on the interconnection and mutual aid operation and control of energy stations is still in its infancy, and there is no equipment and system that can connect various distributed energy stations. Contents of the invention [0003] In orde...
