低频振荡是限制电力系统间输电的主要障碍之一。虽然电力系统稳定器（PSS）已被证明是有效的阻尼内部区域振荡，区域间振荡仍然是当今电力系统的一个关键挑战。由于两个相连的电力系统之间的低频振荡是有功功率振荡，通过能量存储设备（ESD）的功率调制可以是一个有效的和有效的方式来维持这种电力系统的稳定性。在本文中，我们研究了一个新的目标表示启发式动态规划（GrHDP）算法的集成自适应控制ESD阻尼区域间振荡。一个粒子群优化（PSO）为基础的功率振荡阻尼器（POD）也被提出用于比较。基于残差的POD控制器的设计，建议的PSO优化控制器的设计，和基于GrHDP的控制器设计在一个四机两区域的基准电力系统与能量存储设备进行了各种仿真研究。仿真结果表明，在广泛的系统运行条件下，基于GrHDP的区域间振荡阻尼方法的效率和有效性。
Low-frequency oscillation is one of the main barriers limiting power transmission between two connected power systems. Although power system stabilizers (PSSs) have been proved to be effective in damping inner-area oscillation, inter-area oscillation still remains a critical challenge in today's power systems. Since the low-frequency oscillation between two connected power systems is active power oscillation, power modulation through energy storage devices (ESDs) can be an efficient and effective way to maintain such power system stability. In this paper, we investigate the integration of a new goal representation heuristic dynamic programming (GrHDP) algorithm to adaptively control ESD to damp inter-area oscillation. A particle swarm optimization (PSO)-based power oscillation damper (POD) has also been proposed for comparison. Various simulation studies with residue-based POD controller design, the proposed PSO optimized controller design, and the GrHDP-based controller design over a four-machine-two-area benchmark power system with energy storage device have been conducted. Simulation results have demonstrated the efficiency and effectiveness of the GrHDP-based approach for inter-area oscillation damping in a wide range of system operating conditions.
