基于耗散理论的电力微分代数系统干扰抑制

Disturbance attenuation for electric power differential algebraic system based on dissipation theory

为了进一步研究电力微分代数系统的干扰抑制问题,针对一类电力微分代数系统,拓展耗散理论的概念,并利用M-导数方法对有不确定干扰的电力微分代数系统进行控制设计,给出了干扰抑制控制器.仿真结果表明,该方法对此类电力微分代数系统的干扰抑制、提高系统运行的稳定性效果明显.由于模型具有一般性,又考虑了干扰的影响,因此方法的适用范围更广泛,更具有一般性.

In order to study the disturbance attenuation for electric power differential algebraic systems, the conception of dissipation theory was generalized for a class of electric power differential algebraic system. By means of M-derivative method, the feedback control of the electric power differential algebraic system with uncertain disturbance was designed, and the controller with disturbance attenuation was given. The simulation results show that the proposed method is more effective for disturbance attenuation and can significantly improve the stability of the system. Because the model has the universality and the disturbance effect is considered, the applicability of the present method is wider and more general.
