摘　　要：为了解决鲁棒控制问题,提出了一种概率鲁棒随机控制设计方法。将概率鲁棒控制算法成功运用到电力系统控制中,解决电力系统控制的鲁棒问题,能很好地兼顾系统的动静态性能。该方法充分考虑了电力系统中存在的不确定参数及干扰,使发电机组具有较好的鲁棒性能。控制方法的求解过程计算量较小,其解不再是NP-hard的问题。最后,在单机电力系统仿真中,对基于概率鲁棒随机控制方法所得出的鲁棒控制律进行仿真分析与讨论,验证其有效性及优越性。In order to solve the problem of robust control,a probabilistic robust stochastic control design method is proposed.The probabilistic robust control algorithm is successfully applied to power system control to solve the robust problem of power system control which the dynamic and static performance of the system can be taken into account.This method fully considers the uncertain parameters and interference in the power system,so that the generator set has better robust performance.The solution process of the control method is that the amount of calculation is small,and the solution is no longer an NP-hard problem.In the single-machine power system simulation,the robust control law derived from the probabilistic robust stochastic control method is simulated,analyzed and discussed to verify its effectiveness and superiority.
