The Building and Revising Strategy of Load Model Parameter Database

It has been well recognized that the load model has great effects on the power system analysis and control. For the convenience in practicality, it is necessary to build the load model parameter database for the large grid. However, there are large differences between the build of load model database and other power system components because of its special characteristics. In this paper, the building and revising strategy of the load parameter database is proposed based on the researches of field data selection, load classification, model synthesis and load model extension which also provides the guides for the application of the measurement-based load model in large grid.
