Abstract

Abstract In this paper, a cloud-edge-end collaboration-based control architecture is established for frequency regulation in interconnected power systems (IPS). A model predictive control (MPC)-based load frequency control strategy for the IPS with photovoltaic aggregation and energy storage systems under model uncertainty and communication delay is proposed. This can effectively overcome the issues of model uncertainty, random load perturbation and communication delay. First, a state space model for the IPS is constructed. To coordinate the frequency and contact line power fluctuation of the IPS, a robust controller based on the theory of MPC is then designed. Then, considering the communication delay of frequency response commands during transmission, a predictive compensation mechanism is introduced to eliminate the effect of delay while considering model uncertainty. Finally, simulation results verify the effectiveness and robustness of the proposed control strategy.
模型不确定性和通信延迟下PVA和ESS互联电力系统基于mpc的LFC
本文提出了一种基于云边缘协同的互联电力系统频率调节控制体系结构。提出了一种基于模型预测控制(MPC)的具有光伏聚合和储能系统的IPS在模型不确定性和通信延迟下的负荷频率控制策略。这可以有效地克服模型不确定性、随机负载摄动和通信延迟等问题。首先,建立了入侵防御系统的状态空间模型。基于MPC理论,设计了一种鲁棒控制器,以协调IPS的频率波动和接触线功率波动。然后,考虑到频响命令在传输过程中的通信延迟,在考虑模型不确定性的情况下,引入了一种预测补偿机制来消除延迟的影响。最后,仿真结果验证了所提控制策略的有效性和鲁棒性。

期刊介绍: Protection and Control of Modern Power Systems (PCMP) is the first international modern power system protection and control journal originated in China. The journal is dedicated to presenting top-level academic achievements in this field and aims to provide a platform for international researchers and engineers, with a special focus on authors from China, to maximize the papers' impact worldwide and contribute to the development of the power industry. PCMP is sponsored by Xuchang Ketop Electrical Research Institute and is edited and published by Power System Protection and Control Press. PCMP focuses on advanced views, techniques, methodologies, and experience in the field of protection and control of modern power systems to showcase the latest technological achievements. However, it is important to note that the journal will cease to be published by SpringerOpen as of 31 December 2023. Nonetheless, it will continue in cooperation with a new publisher.
