Frequency regulation strategy of DFIG in micro-grid system based on subsection control
摘要
Abstract
In order to fully utilize the potential of frequency regulation capability of DFIGs in micro-grid, this paper presents a frequency control strategy to coordinate inertia control , over-speed control and pitch control .Depending on the operation characteristics of DFIGs and wind speed , DFIGs keep out of frequency regulation during low wind speed.Over-speed control is combined with pitch control during medium wind speed .Pitch control is employed for high wind speed .The control strategy takes the units operation features and the characteristics of frequency regulation as the subsection basis , as well as balances effectiveness and economic efficiency .The simulation results verify the ef-fectiveness of the mentioned control strategy of the frequency regulation .关键词
