This article presents a decentralized optimal controller design technique for the frequency and power control of a coupled wind turbine and diesel generator. The decentralized controller consists of two proportional-integral (PI)-lead controllers which are designed and optimized simultaneously using a quasi-Newton based optimization technique, namely, Davidon–Fletcher–Powell algorithm. The optimal PI-lead controllers are designed in such a way that there are no communication links between them. Simulation results show the superior performance of the proposed controller with a lower order structure compared to the benchmark decentralized linear-quadratic Gaussian integral controllers of orders 4 and 11. It is also shown that the proposed controller demonstrates an effective performance in damping the disturbances from load and wind power, as well as a robust performance against the parameter changes of the power system.

本文介绍了一种用于耦合风力涡轮机和柴油发电机的频率和功率控制的分散式优化控制器设计技术。分散控制器由两个比例积分 (PI) 引导控制器组成，它们使用基于准牛顿的优化技术（即 Davidon-Fletcher-Powell 算法）同时设计和优化。最佳 PI 超前控制器的设计方式使得它们之间没有通信链路。仿真结果表明，与 4 阶和 11 阶的基准分散线性二次高斯积分控制器相比，所提出的控制器具有较低阶结构的优越性能。还表明，所提出的控制器在抑制负载扰动方面表现出有效的性能和风力发电，
