It is expected that increasing amounts of new generation technologies will be connected to electrical power systems in the near future. Most of these technologies are of considerably smaller scale than conventional synchronous generators and are therefore connected to distribution grids, as the DFIG-based wind farm. When connected in small amounts, the impact of wind farm on power system transient...
For a large-scale power grid, how to obtain load model for the substation without load characteristics recorder is the problem facing measurement-based load modeling. The feasibility that the measurement-based load model of a substation is applied to every substation was studied in this paper. The simulation results indicate that it is not feasible. Consequently, two methods were adopted to solve...
The researches on measurement-based load modeling have been continued for more than twenty years in China. However, since lacking of system measured data of major disturbance, it is doubtful for load model generalization capability, and more attentions are also caused for the issue that whether dynamic simulations adopting the measurement-based load model accord with the real system. The measurement-based...
Simulation assessment of error and veracity is the precondition in power system dynamic simulation validation that is directly related to power system stability. Own to the applications of wide area measurement system (WAMS) that could provide synchronous measured information of power grid, it is possible to assess dynamic simulation. Based on the principles of similarity theory and analytical hierarchy...
