Adaptive Interfacing Control Strategy for Electricity Generations from Wind Power to Distribution Grids

Recently electricity generation from wind power has been increasingly popular worldwide as one of the most promising renewable energy sources. This paper proposes an adaptive control strategy for interfacing distributed generations (DGs) from wind power to utility distribution grids. This paper presents the voltage control requirements and protection requirements for wind-powered DGs according to IEEE-1547 standards. This paper defines adaptive interfacing controller for three common types of wind-powered DGs: doubly fed induction generator, permanent-magnet synchronous generator, and squirrel-cage induction generator. The design of the adaptive controller using state-of-the-art digital signal processing technology is presented. The key functions of the hardware components in the adaptive controller are provided.
