PROJECT TITLE :
Analysis and Mitigation of Undesirable Impacts of Implementing Frequency Support Controllers in Wind Power Generation
Wind power generation is increasing, rapidly forming a important half of the power systems of the near future. Thus, incorporating wind power into frequency regulation seems necessary. Droop and virtual inertia are 2 key strategies for involving the wind power in frequency regulation. But, when these strategies are applied, undesirable effects can be induced. But, the mitigation of such impacts has not however been analyzed. The rate of amendment of power (ROCOP) of a wind generator may be a serious issue limiting the effective implementation of frequency regulation methods. Whereas high ROCOP results in wear and will increase the upkeep price, simply limiting the ROCOP of the generator by a ramp-limit control perform will neutralize the desired impact of frequency regulation. In this paper, little-signal analysis is used to check the impact of frequency regulation strategies on the ROCOP of wind turbines considering the 2-mass mechanical dynamics. Each doubly fed induction generator- and permanent-magnet synchronous generator-based mostly turbines are thought-about. An effective solution, based mostly on utilizing the converter dc-link capacitor, is proposed, analyzed, and compared to the conventional ramp-rate limit method in several aspects. Time-domain simulation is used to validate the analytical results.
