This paper presents a preliminary study using adaptive control theory to damp inter-area oscillations in power systems through controlling wind farm that is injecting power into the system. The power system is modeled as a distributed parameter system using a first order hyperbolic wave equation, which represents the dynamics of an aggregate rotor model for a system of coupled swing equations. A direct...
This work investigates inter-area oscillation in large-scale wind-integrated power grids when wind power is injected from multiple wind farms located at different locations. Previous results in the literature have shown that the location of wind power injection is detrimental to the frequency response of interconnected generators. In this work, we seek to find an optimal wind-power injection location...
The purpose of this paper is to analyze the small signal stability of the Uruguayan power system on a short to medium term according to the scenarios for the years 2013–2017, in which the transmission network will undergo major changes: first, the inclusion of large quantities of wind power and secondly, the implementation of major infrastructure projects including the construction of the 500kV line...
An improved control approach for DFIG (doubly-fed induction generator) is proposed, in order to enhance the damping of power systems integrated with wind farms through long distance. Firstly, the impact of wind power on the power system oscillations is investigated. Secondly, a supplementary damping control system (SDCS) is proposed and is added to the conventional DFIG control loop to improve the...
