This paper aims to analyze Variable Speed Wind Turbine impact on transient behavior of a power system using time domain simulation. To this purpose, suitable mathematical models for Doubly Fed Induction Generators and Permanent Magnet Synchronous Generators with their control devices are considered. Simulations allow to assess the influence of VSWT on conventional synchronous generator dynamics after...
Compared to vertically integrated markets, there are a number of practical tools at the disposal of the system operator to correctly manage the power system in deregulated markets. As a consequence, the system operator is inclined to operate the system with ample security margins on network loadability, which limit active power exchanges, and heavily affect the market. In this paper a technique for...
The paper describes the development of a decomposition method which exploits the structure of large power systems. As large power systems are almost invariably composed of weakly connected subsystems, each consisting of strongly interacting machines, the proposed decomposition technique provides, by analysing and quantifying the dynamic interactions among the generating units on the basis of a linearised...
