EasyChair Preprint 11164

Abstract

With the increasing proportion of wind power, the transient behavior of power system has changed, and new instability phenomenon with unknown mechanism has occurred in some high proportion areas. In order to deeply understand the dynamic characteristics of double-fed fans and the mechanism of their interaction with the power grid, and then analyze the influence of large-scale double-fed wind power access on the stability of the power system, this paper adopts TRI co-simulation technology to conduct electromagnetic transient simulation of double-fed wind units in the RTDS system, and obtains detailed transient process data. shapelet algorithm based on mutual information method is used to select the key time series data in stable samples, and the interaction mechanism between fan and power grid is revealed by analyzing these data. This research method is of great significance to explore the transient characteristics of fan - synchronizer interconnected power systems.

Keyphrases: Fan - synchronizer interconnection system, TRI co-simulation, shapelet algorithm
