Analysis of Interval Flow Calculation Algorithm of Multi-Loop Complex Power Network Based on Knowledge Mapping

The continuous integration of high proportion of new energy into the power grid has exacerbated the complexity of the uncertainty of the power system, making the traditional single-point deterministic power flow calculation increasingly difficult to meet the needs of power system planning and dispatching. Interval power flow is an uncertain power flow calculation method based on interval algorithm, which is characterized by only paying attention to the boundary information of the uncertainty, and is especially suitable for the uncertain power flow calculation of high proportion and high permeability new energy connected to the grid. This paper analyzes the shortcomings of the existing mainstream knowledge representation forms for the expression ability of artificial empirical knowledge of power flow adjustment, fully considers the characteristics of the combination of qualitative knowledge and quantitative knowledge in the artificial empirical knowledge required in the process of power flow adjustment, and the combination of related knowledge and rational knowledge, and constructs a knowledge map in the field of power flow adjustment.
