Modeling, simulation, and performance analysis of an isolated hybrid power system (IHPS) consisting of solar thermal power plant, diesel engine generator (DEG), and wind turbine generator (WTG) are done in this paper. Performance of the studied IHPS model has been studied under two different input conditions, viz. (a) step change in load disturbance and wind perturbation and (b) random change in load disturbance and solar and wind perturbation. For better frequency stabilization of the system, proportional–integral–derivative (PID), integral–tilt–derivative (I-TD), and tilt–integral–derivative (TID) controllers are used (one at a time) for controlling governor of the DEG and pitch of the WTG. To obtain better performance for the studied IHPS model, the controller gains are tuned by using quasi-oppositional-based whale optimization algorithm. A comparative dynamic response of frequency deviation profile has been carried out under individual presence of PID, I-TD, and TID controllers. The transient responses of the system pertaining to step and random changes in the load disturbance and solar and wind perturbation are plotted and analyzed. It is revealed from this work that the performance of the proposed TID controller is better than the other controllers for this specific application.

一种新型准对立鲸鱼优化算法对孤立混合电力系统的频率稳定

本文完成了由太阳能热电厂、柴油发动机发电机 (DEG) 和风力涡轮发电机 (WTG) 组成的孤立混合动力系统 (IHPS) 的建模、仿真和性能分析。研究的 IHPS 模型的性能已经在两种不同的输入条件下进行了研究，即。(a) 负载扰动和风扰动的阶跃变化和 (b) 负载扰动和太阳能和风扰动的随机变化。为了更好地稳定系统的频率，使用比例-积分-微分 (PID)、积分-倾斜-微分 (I-TD) 和倾斜-积分-微分 (TID) 控制器（一次一个）来控制调速器风电机组的 DEG 和螺距。为了使所研究的 IHPS 模型获得更好的性能，通过使用基于准对立的鲸鱼优化算法来调整控制器增益。在单独存在 PID、I-TD 和 TID 控制器的情况下进行了频偏曲线的比较动态响应。绘制和分析了与负载扰动以及太阳能和风扰动的阶跃和随机变化有关的系统瞬态响应。从这项工作中可以看出，针对该特定应用，所提出的 TID 控制器的性能优于其他控制器。
