Scene modeling method suitable for planning operation of integrated energy system

Abstract

The invention discloses a scene modeling method suitable for planning operation of an integrated energy system, and the method comprises the steps: firstly collecting photovoltaic output data, wind power output data, electric load data, gas load data, cold load data and thermal load data of a researched region, carrying out the per-unit processing of the obtained data, arranging the data according to time, and generating a scene data set; then, adopting an improved LHS method to carry out sampling and correlation control processing on the scene data set, and obtaining a sample matrix; and finally, clustering the sample matrix by adopting an improved K-means method to form a specific probability scene which retains the characteristics of the original scene. The method overcomes the defects that in the prior art, scene description is inaccurate, and it is difficult to completely adapt to future planning and operation, lays a foundation for subsequent system planning design, operation scheduling and the like, avoids the problem that reliable operation of the system is affected by installation mismatching caused by inaccurate traditional scene prediction methods, and effectively improves the design and operation economy of the comprehensive energy system.
