This paper presents a modal analysis of a two machine power system that includes a doubly-fed induction generator (DFIG). The DFIG's model considers rotor flux linkages as dynamic states and stator flux linkages as algebraic variables. Active- and reactive-power controllers are also modeled. Active power is tracked for optimal power extraction from the wind. Using the power system set of differential-algebraic...
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...
Renewable energy sources have the ability to provide electric power in rural areas whenever available. Although it is cheap, clean and abundant, the variation of output power with the variation of wind speed can cause significant power quality issues, especially in the case of a standalone generation system. This paper studies a network presenting a rural load, such as a small village, fed from a...
