In transmission line, the series compensation is used to improve stability and increases the power transmission capacity. It generates sub synchronous resonance (SSR) at turbine-generator shaft due to the interaction between the series compensation and wind turbine system. To solve this, several methods have been presented. However, these provide less performance during contingency period. Therefore, to mitigate the SSR and also to improve the dynamic performance of hybrid wind and PV system connected with series compensated wind farms, the adaptive technique of the Black Widow Optimization algorithm based Fuzzy Logic Controller (BWO-FLC) with UPFC is proposed in this paper. Here, the objective function is solved optimally using BWO technique. Based on this, the Fuzzy Logic Controller is designed. The results proved that the proposed controller performs the mitigation of SSR. The damping ratios of proposed controller to mitigation of SSR are 0.0098, 0.0139, and 0.0195 for wind speed of 6, 8 and 10 m/s respectively.

在传输线中，串联补偿用于提高稳定性并增加输电能力。由于串联补偿和风力涡轮机系统之间的相互作用，它会在涡轮发电机轴处产生次同步共振（SSR）。为了解决这个问题，已经提出了几种方法。但是，这些在应急期间的性能较差。因此，为减轻SSR并提高串联补偿风电场连接的混合风力和光伏系统的动态性能，提出了基于UPFC的基于Black Widow优化算法的模糊逻辑控制器（BWO-FLC）的自适应技术。纸。在此，使用BWO技术对目标函数进行了最优求解。基于此，设计了模糊逻辑控制器。结果证明，所提出的控制器能够减轻SSR。对于风速为6、8和10 m / s的情况，建议的控制器与SSR缓解的阻尼比分别为0.0098、0.0139和0.0195。
