Since the method of a single subject is difficult to meet the complex system solution and analysis requirements brought about by the access of massive power distribution equipment, energy equipment, sensors, etc., it is urgent to explore a distributed optimization method for edge-cloud collaboration
[0004] At present, some research has been carried out on the collaborative optimization strategy of multi-energy micro-grid groups. Renewable energy is coordinated, and a large number of computing and scheduling tasks are concentrated on the cloud service layer, which has caused huge computing pressure on the cloud; such as patent 202111135606. Method” proposes a two-layer optimization model to solve the coordinated optimal dispatch between microgrid groups and distribution networks, but does not consider the energy mutual aid between adjacent microgrids

The invention discloses a multi-energy micro-grid group optimization method, system and device based on edge cloud collaboration and a medium. The method comprises the steps of obtaining an optimization evaluation result and cloud layer data fed back by an edge service layer; a cloud objective function is established according to the optimization evaluation result and cloud layer data, cloud operation constraints are considered, the maximum operation income is taken as a target, collaborative optimization of the microgrid group system in the region is carried out, the optimal energy transaction amount and the optimal energy scheduling amount are obtained, and then the optimal distribution scheme of multiple kinds of energy is calculated; and issuing the optimal distribution scheme to an edge service layer for the edge service layer to coordinate internal energy redistribution until all micro-grids are operated optimally. According to the method, the micro-grid group optimization calculation speed and the distribution network operation benefit are effectively improved.
Description
technical field [0001] The invention relates to the technical field of optimized operation of micro-grid groups, in particular to a multi-energy micro-grid group optimization method, system, equipment and medium based on edge-cloud collaboration. Background technique [0002] With concerns over the security of fossil energy supply in recent years and concerns over climate and environmental issues. Distributed generation (DG), represented by photovoltaic power generation system (PV) and wind power plant (WPP), has become more and more popular in recent years due to its advantages of economy, environmental protection and flexibility. wider application. However, the output of DG is intermittent and random. Large-scale DG infiltration will cause adverse effects on the safe and stable operation of the power system, such as power quality problems, and bring unprecedented challenges to the stable operation and safety control of the power system. As an effective unit for integrati...
