Power grid load frequency control based on reinforcement learning strategies
为实现新型电力系统中负荷频率的精准控制,有效应对大规模可再生能源接入带来的非线性、随机性和不确定性挑战,采用基于径向基函数(RBF)网络的 Actor-Critic 深度强化学习算法,构建自适应比例-积分-微分(PID)控制的负荷频率控制(LFC)策略.首先对电力系统稳定控制结构与 LFC 面临的困境进行分析,阐述智能控制策略优势并完成建模,进而设计自适应优化系统.通过 Matlab 仿真,将该控制器与基于粒子群优化(PSO)调谐的控制器进行对比分析.仿真结果表明,所提出的控制器显著降低了两个区域的区域控制误差(ACE)4 个误差参数,在最小化 ACE 和减小偏差方面展现出更强性能,有效提升了 LFC 的适应性和鲁棒性,为新型电力系统的构建提供了兼具理论与工程价值的新方法.
To achieve precise control of load frequency in new power systems and effectively address the challenges of nonlinearity,randomness,and uncertainty caused by the integration of large-scale renewable energy,an Actor-Critic deep reinforcement learning algorithm based on radial basis function(RBF)network is adopted to construct an load frequency control(LFC)strategy with adaptive proportional-integral-derivative(PID)control.First,the stable control structure of the power system and the dilemmas faced by LFC are analyzed.The advantages of intelligent control strategies are expounded,and modeling is completed,followed by the design of an adaptive optimization system.Through Matlab simulation,the controller is compared and analyzed with the particle swarm optimization(PSO)-tuned controller.The results show that the proposed controller significantly reduces the four error parameters of area control error(ACE)in the two areas,demonstrates stronger performance in minimizing ACE and reducing deviations,effectively improves the adaptability and robustness of LFC,and provides a new method with both theoretical and engineering values for the construction of new power systems.
