This paper proposes an interconnection and damping assignment passivity-based control (IDA-PBC) for multimachine power systems including hydro-turbine governing systems (HTGS) with surge tank. The main objective is to stabilize the rotor speed and regulate the terminal voltage of each synchronous machine in a power system. The proposed control is decentralized, thus avoiding challenges of communication between generators. Passivity theory is used since the open-loop of the HTGS presents a port-Hamiltonian structure. IDA-PBC allows a control law that maintains the passive structure in closed-loop, guaranteeing its asymptotic stability using Lyapunov's theory. The dynamics of each HTGS are described by an eleventh-order model, which can be reduced to a tenth-order. The proposed control is tested in a 12-bus test system and compared to a standard control, which considers a voltage regulator and exciter based on the IEEE type ST1A excitation system model and power system stabilizer IEEE-PSS1A. The governing system based on a PID control with static and transient droop is also employed. Additionally, the proposed controller is compared to a sliding mode controller. Time-domain simulations demonstrate the robustness and appropriate performance of the proposed decentralized control under different large disturbances.

考虑带稳压罐的水轮机的电力系统无源控制

本文提出了一种基于互连和阻尼分配无源控制 (IDA-PBC) 的多机电力系统，包括带稳压罐的水轮机调节系统 (HTGS)。主要目的是稳定转子转速和调节电力系统中每台同步电机的端电压。所提出的控制是分散的，从而避免了发电机之间的通信挑战。由于 HTGS 的开环呈现端口-汉密尔顿结构，因此使用了无源理论。IDA-PBC 允许控制律在闭环中保持被动结构，使用李雅普诺夫理论保证其渐近稳定性。每个 HTGS 的动力学由一个 11 阶模型描述，该模型可以减少到 10 阶。所提出的控制在 12 总线测试系统中进行了测试，并与标准控制进行了比较，标准控制考虑了基于 IEEE 类型 ST1A 励磁系统模型和电力系统稳定器 IEEE-PSS1A 的电压调节器和励磁器。还采用了基于具有静态和瞬态下垂的 PID 控制的调节系统。此外，所提出的控制器与滑模控制器进行了比较。时域仿真证明了所提出的分散控制在不同大扰动下的鲁棒性和适当的性能。将所提出的控制器与滑模控制器进行比较。时域仿真证明了所提出的分散控制在不同大扰动下的鲁棒性和适当的性能。将所提出的控制器与滑模控制器进行比较。时域仿真证明了所提出的分散控制在不同大扰动下的鲁棒性和适当的性能。
