Research on the VB-Matlab interface method in load forecasting software of power system

Aiming at the VB-Matlab interface issue in load forecasting software of power system, five kinds of common methods for calling Matlab in VB are presented. Taking the actually built load forecasting software as an example,this paper focuses on the use of ActiveX automation technology to connect VB with Matlab, s o that the powerful function of Matlab in image processing and numerical computation and the advantages of VB in the interface design can be integrated. The practical application demonstrates that the method is simple and reliable,and has feasibility and practicality.
