Dynamic Synthesis Load Modeling Approach Based on Load Survey and Load Curves Analysis

摘要

A novel approach to build load model utilizing load curve analysis technique is presented in this paper. Load model has been widely used in power system simulation currently, and its precision directly decides the reliability of simulation result. Through developing load survey and load curves analysis,dynamic synthesis load model can be created and the problem of tlme-varying characters of load can be overcome in certain extent. Besides, three types of data are brought forward to verify the validity of created load model. This approach overcomes the deficiencies of component-based modeling approach cannot be performed frequently and the shortage of measurement-based modeling approach in which created load model cannot be generalized. With the development of computer and communication technology, this approach could create real-time load model in the near future and provide accurate load model for online or offline stability computations.
