In this paper, the impacts of uncertainties in a multi‐machine power system with high penetration of wind farms are studied. The uncertainties associated with generation units, transmission system and demands are considered as the most important sources of uncertainty. So, an innovative optimized type II fuzzy power system stabilizer (PSS) is proposed to decrease uncertainties and increase the power system dynamic stability margin. Membership of the proposed stabilizer is optimized by multi objective particle swarm optimization algorithm using integral of square error until settling and figure of demerit as objective functions. The simulation results verified the performance of the proposed PSS in all operation conditions.

考虑不确定性的风电系统II型模糊电力系统稳定器多目标设计

本文研究了风电场高渗透率的多机电力系统中不确定性的影响。与发电机组，输电系统和需求相关的不确定性被认为是最重要的不确定性来源。因此，提出了一种创新的优化的II型模糊电力系统稳定器（PSS），以减少不确定性并增加电力系统的动态稳定性裕度。通过多目标粒子群优化算法，使用平方误差积分直至沉降和除法系数作为目标函数，对提出的稳定剂的成员进行优化。仿真结果验证了所提出的PSS在所有操作条件下的性能。
