Abstract

The invention discloses a source network load storage coordination level evaluation method based on a risk thought. The source network load storage coordination level evaluation method is characterized in that a source-grid-load-storage coordination level evaluation model is provided under the background that the source-grid-load-storage coordination optimization mode becomes the development trendof the power system; the source-grid-load-storage coordination level evaluation model firstly analyzes internal and external uncertain factors affecting the coordination ability of the system based on the idea of risk identification, and then establishes an evaluation index system considering multi-agent interaction and layering; and secondly, the source-grid-load-storage coordination level evaluation model proposes a quantitative calculation method of quantitative indexes and a processing mode of qualitative indexes, establishes a source-network-load-storage coordination level evaluation model, and determines the weight of each level of indexes by using an analytic hierarchy process and a Delphi method in combination with an empowerment method. According to the constructed evaluation model, the source-grid-load-storage coordination level of the power system is scientifically and systematically evaluated for planning schemes of three areas of a certain province, and a decision reference is provided for planning and operation scheme optimization of the power department, and the intrinsic safety level of the system can be improved.

Description

technical field [0001] The invention belongs to the technical field of electric power systems, in particular to a method for evaluating the coordination level of source-network-load-storage coordination based on risk thinking. Background technique [0002] With the deployment and promotion of the "three types and two networks" development strategy of the State Grid Corporation of China, the construction of a strong smart grid is becoming more and more perfect. Close interaction and collaborative optimization have become an inevitable trend of development. A series of uncertain risk factors have a profound impact on the coordination and interaction capabilities of source, grid, load and storage, and pose a threat to the intrinsic security of the power system. In the current research, the theory and method of comprehensive evaluation of smart grid have become mature, but the evaluation research on the coordinated optimization mode of source-grid-load-storage still lacks a uni...
