Abstract

Decentralization of generation and increasing utilization of information communication systems bring challenges to present power system modeling approaches. This work applies functional modeling for monitoring and modeling of distributed energy resources, with wind turbine generator (WTG) application as a case study.
First, we established a functional model of a generic WTG through the multilevel flow modeling approach. The model acts as basis of a state estimator (SE) for monitoring the WTG. Afterwards, the application of the SE is extended for wind power plant monitoring and control. The case study results show that the SE can efficiently limit the impact of information errors from different data integrity attacks during active power curtailment.
