The positive-feedback-based anti-islanding schemes invented by the authors are highly effective in preventing islanding without causing any degradation in power quality. This paper presents the basic principles of these schemes and their design guidelines. Moreover, their performance is investigated for inverter-based distributed generators (DGs). The parametric study reveals the factors significantly...
In this paper, control of inter-area oscillation in power systems with high wind power penetration is achieved via doubly fed induction generator (DFIG). The DFIG is modeled in Matlabreg/Simulink. A two-area system is investigated with a wind farm connected in the area that exports power. Control schemes for active power and reactive power regulation are designed firstly. The paper finds that without...
With the penetration of wind power being higher and higher in power systems, the impact of wind turbine generation on inter-area oscillations should be fully investigated. This paper discusses the impact of a doubly fed wind turbine induction generator on the inter-area oscillation in a two-area four-machine system. Models of an induction generator and converter/inverter control loops developed by...
